Did you know that choosing a suitcase (or multiple cases, for that matter) in the right size can save you some money in luggage fees and help you become a more organized traveler?

On one end, unused space in your luggage will result in wrinkled clothes and a messy suitcase. Not to mention the extra weight and possible luggage fees. And on the other – having too little space will limit your packing capacity. That’s why nailing the correct luggage size is very, very important.

In this guide, we’ll tell you everything you need to know about all the different luggage sizes, restrictions, and more, so you can understand what size luggage is better for you. Make sure to check out our FAQ section at the bottom if you still have any questions!

Measuring Luggage

Before we talk about different luggage sizes, you should learn how luggage is measured.

Basically, each airline has different size and weight restrictions for hand and checked luggage. Usually, premium airlines will allow slightly larger bags, and cheaper ones will allow smaller ones with tighter weight limits. Your job as the passenger is to find out the restrictions yourself because they change all the time, and it would be impossible for us to list and update each airline individually.

There are two types of size restrictions that you need to know. The first one is dimensions – height (top to bottom), width (side to side), and depth (front to back). It will usually be applied for personal items and carry-ons and could be stated as follows: 55 x 35 x 25 cm (22 x 14 x 9 inches). Airlines will usually offer measuring boxes inside airports, where you can put in your bags to check if they fit.

The second measurement is linear inches. Linear inches just means the total sum of height, width, and depth, and it’s mainly used for checked luggage, which needs to be under 62 linear inches. So to get linear inches, measure the height, width and depth individually and add them all up.

To measure the dimensions of your suitcase, you can place it next to a wall and measure the height, width, and depth by placing a measuring tape next to the wall. To get a more exact measurement, you can place a book or something flat on the other end of the measuring tape. Make sure to include the wheels, handles, and anything else that’s sticking out! Another thing to keep in mind is that fabric suitcases might become a bit larger once they’re packed to the brim, so before measuring, pack your suitcase full and measure in the widest end.

Hand Luggage

Hand luggage means all the bags that you’re allowed to take with you on the plane without checking them in. Usually, it’s a carry-on, a personal item, and any other items that aren’t counted towards the allowance, such as duty-free items.

Hand luggage has to be stored under each passenger’s front seat or in the overhead compartments, which are located above each seat. You won’t be able to access it during take-off and landing because they have to be tucked away securely in case of an emergency.

When you arrive at the airport, you won’t need to go to the check-in desks if you have just hand luggage, and you’ve already printed your tickets back home. You’ll be able to go straight to security, where TSA (Transport Security Agency) will screen your hand luggage for any prohibited items. After that, you’re free to do duty-free shopping or wait at the designated gate until boarding starts.

Carry-on Luggage vs Personal Items

The main difference between carry-on luggage and personal items (other called “underseat luggage”) is that carry-ons need to be stored in the slightly-larger overhead compartments and personal items under each passenger’s front seat. Usually, most people choose smaller rolling suitcases as their carry-ons and backpacks, duffels, or tote bags as their personal items. That said, you can use any type of bag as a carry-on or a personal item, whether it’s a briefcase, rolling suitcase, duffel bag, backpack, tote, or even a regular shopping bag.

You won’t really be able to access stuff from your carry-on during the first and last 15-30 minutes of the flight, as well as any turbulence, so pack your most necessary items in your personal item, such as your laptop, headphones, e-reader, any medicine, e.t.c.

Personal Item Size and Weight Requirements

Most airlines won’t specifically mention an exact size requirement for personal items, and instead, they’ll just say that it has to fit under the front seat. On average though, it should be 6-9 inches in width, 10-14 inches in height, and 17-18.5 inches in length. They avoid stating the exact measurements because each airline has different types of aircraft in their fleet and each aircraft has a different amount of space under each seat. To get the exact personal item size requirements, you should probably ask the airline directly, or check our list where we compiled personal item restrictions for most popular airlines.

Some airlines also have individual weight restrictions for personal items. But most of them just have some kind of weight limit for the total weight of your personal item and carry-on.

Tip: Looking to purchase a personal item? Check out the Matein Travel laptop backpack, which I’ve used as my personal item on multiple flights without any issues. It always fits under the front seat and it’s surprisingly spacious.

Carry-on Size and Weight Requirements

On average, carry-ons usually have to be 8-10 inches in width, 13-15 inches in height, and 19-23 inches in length. Each airline has different carry-on size requirements, however, the most popular one is 22 x 14 x 9 inches. The restrictions are so different between airlines because the overhead compartments tend to differ in capacity across different aircraft.

In terms of weight, each airline has different weight requirements for carry-on luggage. Most airlines in America don’t have any weight requirements for hand luggage but some do, especially budget airlines. If the airline has a carry-on weight limit, it’s usually between 15-35 lbs (7-16 kg). Some airlines will also have a specific weight limit for the total weight of carry-ons and personal items.

Tip: Looking for a new carry-on? I’ve used the Travelpro Maxlite 5 19-inch fabric carry-on for a while now and I love it. It’s spacious, lightweight, and very durable. Even though it’s slightly over the limit in width, I’ve never had any issues with that on international flights.

Domestic Carry-Ons vs International Carry-Ons

When you’ll be shopping for a new carry-on, you’ll notice that some of them will be marked as “international carry-on” and some as “domestic carry-on.” That’s because carry-on size restrictions are usually stricter for international flights and looser for domestic ones. If you’re flying domestically, you might get away with a 23-inch (longest side) carry-on, but on an international flight, you’ll probably be limited to 19-21 inches.

So essentially, domestic carry-ons will be slightly larger than international ones. If the carry-on is too large, you will be asked to check it in, and you’ll have to pay additional fees. That’s why it’s important to buy a smaller carry-on if you’re planning on flying internationally. Usually, international carry-ons will have to be under 22 x 14 x 9 inches.

Hand Luggage Fees

Almost all airlines will allow bringing one personal item completely for free. When it comes to carry-ons though, most airlines allow bringing one for free, but budget airlines might charge a fixed fee depending on your class, which could be anywhere from 10$ to 50$. For instance, Spirit airlines will charge 31-50$ for carry-on luggage and Ryanair will charge about 6-20 EUR.

Keep in mind that most of these items are usually allowed for free in addition to other hand baggage:

Assistive devices for the disabled
Jackets
Umbrellas
Diapers
Other wearable clothes
Walking canes
Food in disposable containers meant to consume on the airplane
Child restraint seats
Strollers
Duty-free items
Reading materials
Cameras (some airlines consider cameras as personal items, while others don’t.)
Pet carriers (Some airlines consider pet carriers as personal items, while others don’t.)

Hand Luggage Advantages and Disadvantages

Using only hand luggage and avoiding checked luggage altogether is a technique used by many, me included because it offers many benefits:

No need to wait in line at the check-in counter
Most of the time, completely for free
Less likely to be stolen or lost because it’s on you at all times
Easier to carry around, especially if you use a backpack as a personal item together with a carry-on suitcase
The best place for keeping valuables and fragile items
You can access all of your items during the flight
Less likely to break because it isn’t exposed to baggage handling

However, there are some drawbacks to using only hand luggage, such as:

Less packing space
Harder to manage for families because they usually need to bring more items
It needs to be lugged around the airport after security instead of being handed over at the check-in desks
Usually, has much stricter weight limits

Tips for Buying Hand Luggage

If you’re flying on short flights, consider using only an underseat rolling suitcase or backpack. People who fly for business often only need to fly out domestically for a quick meeting, so a lot of them travel with only a personal item. You can easily fit a spare shirt in there as well as some toiletries and a laptop, which is really all you need.
For up to two-week vacations, a carry-on and a personal item offer more than enough space. Personally, I’m a light packer, and I can travel for up to three weeks or even a month using only a carry-on and a personal item. For most people, this offers enough space.
Consider getting a backpack with a back strap as your choice of personal item. That way, you can secure it around the retractable handle on top of your carry-on, which makes it incredibly easy to lug around. Especially in crowded areas, such as public transport and airports.
If you’ll be flying internationally, get a carry-on under 22 x 14 x 9 inches with wheels and handles included. On domestic flights, you’ll probably be able to use something larger, but if you want to avoid paying extra fees down the line, make sure your carry-on is under this limit.
Make sure to get lightweight hand luggage. The weight restrictions are pretty strict as it is already, so make sure to get a lightweight carry-on and personal item. Especially the carry-on, because you’ll have to stow it in the overhead compartments. So instead of going with a hardside carry-on, get a fabric one instead, which will most likely be lighter.

Checked Luggage

Checked luggage is all baggage that’s too large or too heavy to be carried on the flight, and has to be checked in instead. This means that you’ll need to hand it over at the check-in counters at the airport. The baggage will then be transferred over to baggage handling and it will be loaded in the cargo hold of the airplane. When you land, you’ll have to pick up your checked luggage from the luggage conveyor belts in the baggage reclaim area.

You can use other kinds of baggage as well for checked luggage, not just suitcases. You can also use large backpacks, duffel bags, totes, musical instruments in their cases, large trunks, and other oversized items. A lot of times, you’ll have to check in specialty items, such as large musical instruments and all kinds of sporting equipment, such as bicycles, snowboards, golf clubs, e.t.c.

Checked Luggage Size and Weight Restrictions

Most commonly, checked luggage will have a size restriction of 62 linear inches (height + width + length) and a weight limit of 50 or 70 lbs. These are the IATA guidelines that are enforced in the EU and US which are there to keep the baggage handlers from handling too heavy bags. Oversized and overweight baggage will be accepted, but it will be labeled as oversized/overweight and you’ll have to pay a fee for that unless it’s sporting equipment. For instance, American Airlines will accept oversized bags up to 126 linear inches (320 cm) and overweight bags up to 100 lbs (45 kg.)

Small vs Medium vs Large Checked Luggage

Checked luggage comes in different sizes, and usually, the longest dimension is 23-32 inches long. Depending on the longest side, checked luggage is usually divided into three sizes, which are small, medium, and large. Small checked suitcases usually are 23-24 inches on the longest size, medium ones 25-27 inches, and large ones in 28-32 inches. Quite often, suitcases above 30 inches will actually be oversized, because they’re over 62 linear inches with wheels and handles included.

For most people, a medium checked suitcase will be the best option, because it will be just within the checked luggage size limits and offer a large amount of space for all of their items.

Checked Luggage Fees

On most international flights, airlines will allow you to bring one or two checked bags completely for free. On domestic flights, usually, they’ll offer either one free checked bag or none at all. This depends a lot on the airline though. Additional bags will cost on a per-bag basis, starting with cheaper rates and continuing with more expensive ones. For instance, for American Airlines on domestic flights, the first checked bag will cost 30$, the second 40$, and the third one 100$.

If you aren’t flying alone and you’re carrying a lot of checked bags, it’s usually a better idea to split them evenly among all the passengers to save some money on the checked baggage fees. It also isn’t advisable to bring more than two checked bags because the fees start to get pretty costly after that.

The fees for overweight and oversized luggage can get very expensive, upwards of 100-200$ for each bag, so before you arrive at the airport, make sure that each bag is under the weight limit.

Checked Luggage Advantages and Disadvantages

Although there are a lot of disadvantages for flying with checked luggage, there are some advantages as well, such as:

Checked bags offer much more space
Better for families who carry a lot of items
Checked bags don’t need to be carried around the airport after checking them in
No need to worry about size and weight, as the restrictions are pretty hard to reach
You should be able to get away with a slightly oversized checked bag because they’re rarely measured

However, there’s a reason why I don’t travel with checked luggage. In my opinion, it has more disadvantages, such as:

With a personal item, carry-on, and a checked suitcase, it’s much more difficult to use public transport
Checked luggage is mostly a paid service, especially with budget airlines
There’s just too much space if you’re a light packer
Checked bags can get damaged from baggage handling
Items get lost or stolen much more frequently when packed in checked luggage
You won’t be able to access the contents of checked luggage during the whole flight
In case checked baggage gets lost, you’ll be left without a lot of items and your trip might be ruined
You’ll have to wait in the check-in line at the airport

Tips for Buying Checked Luggage

Avoid plastic checked suitcases. Hardside ABS, Polycarbonate, or Polypropylene suitcases can crack pretty easily. When they’re thrown in the baggage area under a pile of other suitcases, this can happen very easily. That’s why you should choose an aluminum checked suitcase or a fabric one, which will be much less likely to break.
Before buying a checked suitcase, double-check that it’s below 62 linear inches. Oversized checked luggage fees can get pretty expensive, usually between 100-200$. To avoid this hefty fee make sure that your suitcase is below 62 linear inches (height + width + depth) with handles and wheels included. A very large amount of large checked suitcases, in fact, about 50-80% of them are oversized, so pay close attention to the dimensions.
A medium checked suitcase (25-27 inches) is more than enough for most people. Usually, medium checked suitcases are 58-61 linear inches in size, which is just below the 62 linear inch size limit, so when you’re looking for a checked suitcase, get one in this size.
Get a bright or patterned checked suitcase. Checked luggage gets lost much more frequently. So when you’re shopping for a new case, make sure to get one that’s colorful and easy to recognize. It will be much easier to spot on the baggage carousel and if it gets lost, the chances of finding it will be much better because you’ll be able to describe it better. If you already own a dark checked suitcase, get a colorful patterned luggage cover.
Avoid checked luggage with spinner wheels. Rolling, inline (2 wheels) suitcases are better options for checked suitcases because they’re much less likely to break while the bag is checked in. Spinner wheels are much more likely to fall off because they’re extended out from the main shape of the suitcase. It’s actually one of the most common things that break on checked bags.
Consider getting a pelican trunk instead of a typical checked suitcase. They’re basically indestructible and they’re one of the most popular choices for climbers, camera crews, and other people who need to bring a lot of expensive checked gear.

What Size Luggage Should You Get?

There are all kinds of different factors that determine what kind of suitcase you should get. Before buying any luggage, you should understand how often and where you’ll be traveling, how many people you’ll be flying with, what are your packing traditions, and so on.

Are You an Over-Packer?

There’s nothing wrong with being an over-packer, but it will affect what kind of luggage you should choose and how much you’ll be paying in fees. Most over-packers like to travel with a checked suitcase and a personal item, such as a small backpack, skipping the carry-on entirely. You’ll be able to pack your valuables and essentials in the personal item and be left with a very large amount of space in your checked suitcase, where you can pack all of your clothing and anything else you’d need. A medium checked suitcase will usually offer about 90-100 l of space while a carry-on only 35-50 l, so the difference is pretty significant.

How Long You’ll Be Traveling?

The length of your trips/vacations also determines what kind of luggage you should get. If you’ll be traveling for months, unless you’re an extreme minimalist, you’ll need to bring some kind of checked luggage. But for two to three-week trips, it’s perfectly fine to bring only a carry-on and a personal item, unless you’re an over-packer or you need to bring other kinds of gear for your job, planned activities, e.t.c.

Where You’re Flying to and What Are Your Planned Activities?

Think about what you’ll be doing and what gear you’ll need. Do you need scuba diving or skiing gear? Are you into photography and need to bring a large tripod? Are you flying to a cold-weather country and you need to bring a lot of extra warm clothing? The kind of travel that you’ll be doing, determines what size luggage you should get.

Think about valuable and fragile gear specifically. Try to keep the most valuable items in your hand luggage. If that isn’t possible, remember to ensure your gear and invest in a durable, large enough, checked suitcase or trunk. A good option for that is the pelican trunk, which is the industry standard for professionals.

Tip: It’s Better to Buy a Smaller Suitcase, Instead of a Larger One

Many people will probably disagree but I personally think that it’s always a smarter choice to buy a smaller suitcase instead of a larger one. This will make you become a lighter packer, which could end up saving you some money in the long run on checked baggage fees.

A lot of times, people are bringing gear that they don’t really need and end up with heavier, oversized suitcases. Remember that you’ll also have to carry your luggage around the town and to the airport. You’re on a vacation to get new experiences, not buy a lot of unneeded stuff, and be exhausted from carrying an oversized suitcase. Of course, if you’re traveling for work, that may not be true, but for general leisure travel, it’s a better idea to get a slightly smaller suitcase than you think you’d need.

What Size Luggage I Use Personally

I usually travel one or two weeks at a time, so a personal item (backpack) and an international carry-on are more than enough to fit in everything that I need. I rarely use checked luggage because I’m a minimalistic packer.

My favorite has become the Matein laptop backpack for a personal item, which fits perfectly under the front seat and has many neat compartments for everything that I need. It’s 18 x 12 x 7.8 inches large, but I never pack it full, so it always fits under the front seat.

And for the carry-on, I use the Travelpro Maxlite 5 International 19-inch carry-on, which is pretty light and small enough for domestic luggage restrictions. It’s 21.75 x 15.75 x 7.75 inches large with wheels and handles included, so sometimes it’s a little bit above international limits, but I’ve never had any issues with it. I’ve tried squeezing it inside the measurement boxes myself, and I managed to fit it in with a tight squeeze.

My laptop backpack has a rear strap that wraps around the carry-on’s retractable handle so my backpack can be secured on top of it. It’s handy because my carry-on has spinner wheels, and it’s super easy to move around. In tight spaces, for instance, in the subway, it’s much easier to store the backpack on top of the carry-on.

If you’re a light packer like me, I’d suggest going with a backpack and a carry-on. It’ll be enough for 1-2 week trips, but if you wash some clothes midway and don’t buy too many souvenirs, you can stretch that to three weeks or even a month. If you’re traveling longer than that or you’re an over-packer, you should get a 25-27-inch medium checked suitcase instead of the carry-on.

Frequently Asked Questions About Luggage Sizes

What’s the largest luggage size for checked-in luggage (62-inch luggage)?

In order to comply with the 62-linear-inch checked luggage size requirement, you shouldn’t get a suitcase larger than 29-30 inches (longest side.) Almost all 31 and 32-inch suitcases will be oversized. Even a lot of 28-30-inch suitcases are oversized, so you have to double-check the product description and find out how large they really are. Count the total sum of the height, width, and depth, with wheels and handles included to get the true linear-inch measurement. The largest suitcases within the 62-linear-inch restriction are about 100-120l in volume.

To maximize the amount of space that you can have inside, choose a fabric suitcase, which will open from the top, instead of the middle, as you see on most hardside cases. This means you’ll have a larger main compartment. Also, make sure to get it with inline rolling wheels, instead of spinner ones, which results in a lot of unused space.

Tip: If you want to maximize the amount of space you get from a 62-linear-inch checked suitcase, get the Pelican 1615 travel case, which is exactly 62 linear inches in size and is virtually indestructible.

What’s the largest size for hand luggage?

When we talk about hand luggage, there are different restrictions for personal items and carry-ons. There are also different restrictions for each airline. In general, personal items should be below 17 x 10 x 7 inches in dimensions and carry-ons under 22 x 14 x 9 inches.

The largest size restriction for personal items that we found was on Southwest airlines, where personal items need to be under 18.5 x 13.5 x 8.5 inches. The largest size restriction for carry-ons was on Alaska Air, which was 24 x 17 x 10 inches. Generally, more expensive airlines will have looser restrictions for hand luggage.

What are the 3 luggage sizes?

If we’re talking about dimensions, the three luggage sizes are height (from top to bottom), width (from side to side), and depth (from front to back).

If, however, we’re talking in terms of luggage types, what people most likely mean with the 3 luggage sizes is personal items, carry-ons, and checked luggage, which have three different size and weight restrictions.

What’s the best luggage size for 20 and 23 kg?

The most common weight restriction for checked luggage on budget airlines is 20 or 23 kg (44 or 50 lbs). The best luggage size for this weight restriction is between 25-29 inches (longest size). That’s because 20 or 23 kg checked luggage has to be under 62 linear inches (157 cm). You can calculate the linear inches by adding up height, width, and depth. Most suitcases above 29 inches will be over this limit, which means you’ll have to pay oversized baggage fees. You should always include the wheels and handles in these measurements.

Can I use backpacks and duffel bags as hand/checked luggage?

Yes, you can use backpacks and duffel bags as checked luggage. Theoretically, you can use any type of bag as checked luggage, as long as it’s durable enough to withstand baggage handling. You could even use a cardboard box, although it may not be a wise idea.

Personally, I’ve only traveled with a large backpack as my checked luggage. That’s because I do a lot of hiking and my hiking backpack is much larger than a carry-on. It’s pretty common for people to travel only with a large backpack (not only hike) and keep their essentials in a plastic bag or a tote bag during the flight. This gives you a lot of freedom because everything you need is packed inside one large backpack.

Do I need to include wheels and handles when measuring luggage?

You always need to include wheels, handles, and other elements that are sticking out when measuring luggage. A lot of people don’t know this and they end up purchasing oversized luggage, only to regret it later. You also need to take into account that if you’re buying an expendable suitcase, it will become a few inches wider when expanded.

What size luggage should I use for a week-long trip?

For a week-long trip, everyone should be able to fit everything they’d need in a carry-on and a personal item. Some people struggle with over-packing and end up using checked luggage for week-long trips, which can be avoided with smarter packing choices. When packing for your trip, always lay everything out and re-evaluate each individual item individually. Ask yourself if you’ll be using these items on your trip. And if the answer is “Maybe” you should leave that specific item at home. Personally, I can fit everything I’d need for 2-4 weeks in a single carry-on and a personal item.

What if my checked luggage is oversized?

IATA, which is the largest worldwide airline regulator, states that checked bags can’t be over 62 linear inches in order to keep the baggage handlers from working with oversized bags. Anything over 62 linear inches will be labeled as “oversized” and will cost you an extra 100-200$, depending on the airline.

Even if you pay the hefty oversized luggage fees, there is a limit to how large checked luggage you can bring. Each airline considers this individually, and, for instance, American Airlines will allow oversized bags up to 126 linear inches (320 cm).

The rules are slightly different for sporting equipment, though. Bicycles, for instance, will almost always be allowed, even if they’re oversized, and their luggage fees won’t be as expensive.

What if my checked luggage is overweight?

Overweight checked luggage is allowed, but will be marked as overweight and will cost an additional 100-200$, depending on the airline. IATA states that checked baggage can’t weigh over 70 lbs (31 kg), to protect the baggage handlers from working with overweight items, so anything over that will be marked as overweight. Each airline has a different limit on overweight checked luggage. For instance, American Airlines will allow checked baggage up to 100 lbs (45 kg).

Do carry-on measurements need to be exact?

Unfortunately, carry-on measurements need to be exact. Most airlines have measurement boxes inside airports, which are in the exact measurements of their restrictions. If your carry-on looks oversized, they’ll ask you to put it inside the measurement box. Carry-on suitcases aren’t really flexible, so you won’t be able to get away with an oversized carry-on. If, on the other hand, you’re using a duffel bag or a backpack as your carry-on, then you might get away with a slightly oversized bag, as you’ll be able to squeeze it inside the measurement box.

Should I get hard or soft luggage?

There are pros and cons for both, but I personally tend to lean towards fabric luggage. It’s lighter, less likely to crack or break, and you can extend it slightly outwards if you’ve over-packed. On the other hand, hardside luggage offers more protection to your items and is better-looking in my opinion. Modern hardside suitcases made from Polycarbonate are also pretty durable and don’t weigh much more than comparable fabric alternatives. So it doesn’t really matter that much whether you choose a hardside or softside bag – it’s more a matter of preference.

The only real instance where I wouldn’t use a hardside plastic suitcase is in checked luggage. They’re put under a lot more pressure from baggage handling and quite often, they get thrown around and placed at the bottom of a pile of checked suitcases. They’re much more likely to each up with cracks or dents, so using a fabric-checked suitcase would make more sense.

Should I get a rolling or spinner suitcase?

There are advantages to both, but generally, it’s better to stick with spinner suitcases for carry-on luggage and rolling ones for checked luggage. That’s because while spinner suitcases are much easier to move around, they’re much easier to break off the suitcase. And in checked luggage, they’re much more likely to break off from luggage handling.

Rolling suitcases will usually be more spacious because the wheels are somewhat integrated within the main frame. On spinner suitcases, they’ll extend outwards of the suitcase, which results in a lot of unused space underneath the suitcase. Remember that the wheels are counted towards the total measurements.

But if you’re having back problems or in general lugging around a suitcase gives you hard time, then a suitcase with spinner wheels might make more sense. Compared to inline rolling suitcases, they’re much, much easier to move around – they practically roll by themselves.

How much luggage can I bring on international flights?

Most airlines will allow one personal item and one carry-on for free on international flights. As for checked luggage, most airlines will allow one or even two checked bags for free for each passenger, and the rest will need to be paid for with additional fees, ranging from 30-100$. In general, the fees increase for each next checked bag and could be as follows: 30$ for the first checked bag, 40$ for the second, and 100$ for each next one.

You’ll be able to bring up to 10 checked suitcases (even though it’ll cost a small fortune!) but on some international destinations, a bit less. Airlines operate within the rules set by airline regulators, and in some countries, each passenger can have only two or three checked bags.

How many pieces and what size should a luggage set be?

Most luggage sets come in three pieces: one carry-on (19-23 inches), one medium checked suitcase (25-27 inches), and one large checked suitcase (28-32 inches). I would advise against getting a 3-piece luggage set like this because quite often, the largest piece in the set is oversized, which means that it’s above the 62 linear inch limit and you’ll have to pay oversized luggage fees.

Instead, it would be much more beneficial to get a 2-piece set containing a carry-on and a medium checked suitcase, or a 3-piece set that also contains a personal item (underseat bag). If you’re getting a 3-piece set with a large checked bag, make sure that it isn’t oversized.

Luggage sets are often cheaper to get than buying each piece individually, so it’s quite often a smarter choice to buy a whole set.

Final Words

Getting the right size luggage is really important because if it’s oversized, you might end up paying extra in fees, or just end up with a lot of unused space. For anyone new to traveling, I’d advise getting a small backpack as a personal item and a carry-on that’s within 22 x 14 x 9 inches. This is more than enough for most trips, and I’m usually able to squeeze in everything needed for 2-4 weeks in there. If you’re an over-packer, you might need to swap that carry-on with a medium checked suitcase, which would be 25-27 inches in size (longest end).
