Guide to Suitcase & Luggage Sizes | You Could Travel (2024)

With so many suitcase sizes out there, it can be a daunting task to understand which is the best cabin luggage, lightweight suitcase or best travel backpack for your needs. Do you need a large suitcase or a small suitcase? What is the best size and why? How many clothes can I fit in which suitcase? Do you need to purchase hard shell luggage or lightweight carry-on luggage only?

In this article, we will explain the suitcase sizes and help you understand what type of luggage you need and for what purpose. The perfect suitcase size depends on where you are travelling, for how long and which airline you are travelling with. Each trip might require a different suitcase. Hence, there are so many different luggage sizes.

We know how much we struggled to find the best suitcase size for our long-haul flights and road trips across Europe. Let's dig in and find the most suitable suitcase size for you.

Standard Suitcase Sizes

I have put together a list of the most common suitcases sizes for you. When looking for suitcases online or in the shop, have this chart with you.

Remember to check the exact sizes of the suitcase to ensure they fit the airline allowance as well as the internal capacity (volume).

It's important to remember that a hard shell luggage will usually be smaller in capacity than a soft-sided suitcase, even if their volume is the same. This is because when you pack a soft shell suitcase, it can expand a little, accommodating more of your clothes.

A four-wheel spinner also has a little smaller capacity than a two-wheel suitcase, but its overall size is often a bit bigger. That's because the size of the suitcase is measured from the ground and includes the wheels. On two-wheel suitcases, the wheels are typically recessed, while the four-wheel spinners have their wheels fully out.

And finally, please remember when you buy suitcases online to check the weight of the suitcase. Ideally, you want a lightweight suitcase, especially if you are buying a large or extra-large one. These will be difficult to carry when full, so best to look for the lightest ones.

Small cabin suitcase (hand luggage)

A small cabin suitcase, also called the hand luggage, usually measures 48 cm or 18 inches in height. The capacity of the hand luggage is maximum 40 litres.
You can use a small cabin bag on pretty much all airlines. This is your luggage, which you are allowed to take with you onboard during your flight, at no extra cost.

The standard size of a hand luggage is 45x32x18cm (18x13x7inch).

Why buy a hand luggage? The smallest of the suitcase sizes, the small cabin bag - no wheels (or one with wheels) is perfect for business travellers who only need their laptop and a few essentials with them. Because of the high luggage fees, carry-ons got popular. Now companies are making carry-ons designed to be as space efficient and easy to use, so you can get more of your things on board. Carry-ons are also great for travellers who have a large checked-in luggage and don't want to carry anything else but their papers, electronics, and valuables on board.

Why not buy? Cabin suitcases are not recommended on their own for long trips due to their small size and lack of space.

Large Cabin Suitcase

The large cabin suitcase usually measures 55 cm or 20 inches in height and has a capacity of up to 45 litres. Large cabin bags are perfect for short-haul flights, trips which last only a few days.

If you are looking for standard-sized cabin luggage, this is your best option.

They are also ideal for budget travellers, travelling on low-cost flights, who purchased checked-in luggage or priority boarding. Most airlines accept 55 cm (20 inches) cabin suitcases. (See tables below for individual airlines carry-on allowances.)

The size of a standard cabin luggage is 50x36x23cm (20x14.4x9.2inch).

Why buy this? Large cabin suitcases are perfect for business travellers staying a few days at their destination. The large cabin suitcase with four wheels is also perfect for short-haul flights. If packed well, you can fit enough items to keep you going for up to 5 days abroad.

Why not buy? Large cabin suitcases are pretty good. I can't think of anything negative about them. You might want to consider buying a smaller one if you travel short-haul for only 2-3 days. You will likely need a Medium Suitcase for holidays longer than 1 week.

Extra-large Cabin Suitcase

The size of an extra-large cabin suitcase is around 56 cm or 22 inches in height, with a capacity of up to 50 litres. This is more spacious than the standard large cabin suitcase, adding an extra 5 litres in capacity. We often take an extra-large cabin suitcase with us even if it isn't full, so we have extra free space for souvenirs and other things we buy during our trip.

However, most airlines accept suitcases which have maximum dimensions of 55 cm (20 inches), so you might find yourself in a situation where you actually have to pay to check in this type of luggage. The best thing to do is to check with the airline when you book the ticket.

The extra large cabin suitcase size is 56x38x24cm (22x15x9.5inch).

Because of the above size restrictions, a 24-inch luggage can't be classed as a carry on? A 24-inch bag is too large to bring on board of most airlines.

Why buy this? If you are a frequent flyer with a specific airline carrier who allows you to take on board a cabin bag with these dimensions. This size is also a great option to check in for long-haul flights, alongside your carry-on bag.

Why not buy? You might have issues with the size and weight of these suitcases. Consider the distance from the airport to your accommodation. If you have to walk or take public transport a lot, maybe get a smaller suitcase or consider purchasing a spinner suitcase set.

Medium Suitcase Size

A medium suitcase measures 68 cm or 24 inches in height and has a capacity of up to 75 litres. This is a fantastic option to check in on short-haul flights alongside your carry-on.

The standard medium suitcase size is 60x43x26cm (24x17x10.5 inches).

Medium Size Suitcases are also great for short multi-city stops as it's relatively lightweight and small enough to be practical to carry around with you. It usually fits comfortably into a taxi and it's not too much hassle to carry it on public transport.

Why buy this? If you want to check in your luggage, but need a small enough luggage for you to freely move around during your travels. Take a look at the four-wheel, spinner suitcases for additional convenience. These are easy to roll around and won't fall over all the time.

Why not buy? We can't find any fault with this size. Consider how much stuff you need and if you think it will fit, go for it. Medium Size Suitcases are usually large enough to fit clothes for about 7 days.

Large Suitcase Size

Out of all the suitcase sizes out there, large suitcases are perhaps the most popular for travellers wishing to check in their luggage.

The large suitcase measures 74 cm or 27 inches in height and has a capacity of up to 117 litres. These suitcases are versatile, spacious and allow you to have a series of outfits with you. The large size gives you the freedom to pack whatever you need for your travels which last longer than 1 week.

The standard large suitcase size is 69x47x35.5cm (27x18.5x14inch).

Why buy this? The large suitcase is ideal for long trips, especially if you need to pack for more than one traveller. We recommend you to buy the large, four-wheel spinner version (28 inch) as they will be easier to roll around.

Why not buy? This size can be too big for some. Check the amount of stuff you want to take with you and based on the length of your stay ask yourself. Do I really need this size?

Pro Tip: Always check the checked baggage weight allowance for your flight. These suitcases are easy to fill up, as they are so big, and they might become too heavy. A good rule of thumb: Aim for no more than 20 kg (44 lb) weight.

Extra-large Suitcase Size

This suitcase measures 85 cm or 32 inches in height and has a capacity of up to 130 litres. This is ideal for long stays or expats moving abroad.

We usually travel with 2 extra-large suitcases when we do long-term travel, longer than 2 weeks, that is. We also used these suitcases when we moved abroad, travelled to Japan and New Zealand. Probably one of the best investments to date.

Remember, if you fill up this suitcase to the rim, it might be too heavy for you to carry. As always, we recommend buying the four-wheel version, which is much easier to roll around. Also, consider booking a taxi between the airport and your hotel, so you don't have to carry this suitcase on public transport.

Why buy this? Perfect if you stay long-term in one destination as you can carry all your belongings in it. This is an excellent choice for families travelling with children as well.

Why not buy? This is a huge suitcase, and it can get inconvenient to carry around. Important to note: many airlines have weight limits, usually maximum 35 kg for each luggage, for checked-in bags. Always check with your airline to ensure your luggage is not overweight.

How to measure suitcase sizes

I find that the best to get this out of the way first. You only measure suitcases one way - the way the airline will measure it.

How to measure the external suitcase size:

• Find a measuring tape.
• Place the suitcase on the floor.
• Measure the height of the suitcase from the ground to the top of the carry handle.
• The length of the luggage measured at its largest points, including wheels, pockets.
• The width is measured at the widest part of the suitcase, include wheels and pockets.
• Don't include the pull-out handle when you measure your suitcase.

Remember, the measurements which come with the suitcase are always the external dimensions. Manufacturers won't always give you the internal measurements of the suitcase.

How to measure the internal suitcase size (volume):

• Find a measuring tape.
• Place the suitcase on the floor, fully open.
• Measure the height of the suitcase from edge to edge.
• The width is measured at the widest part, edge to edge.
• The depth of the luggage is measured from the rim to the cover.
• Measure both sides, as the top is usually smaller.

Now, to get the volume of the suitcase (internal capacity) multiply the values you measured for the sides of the suitcase and add up the results. The result is the volume of the suitcase.

Height x Length x Depth = Volume (top)

Height x Length x Depth = Volume (base)

Volume (top) + Volume (base) = Suitcase Volume

What is the difference between volume and capacity?

These are the same and interchangeable. We often say volume when we talk about how much space you have in the suitcase, and capacity when we talk about how much stuff you can really fit. I am sure I am not the only one who tried to fit an extra jumper in, even when my suitcase was already full.

Capacity > Volume

Which suitcase suits your style of travel?

I have created a useful list of traveller types and what suitcases I recommend for them and why.

With so many suitcase sizes available on the market, it is important to first check the airline's luggage policy and baggage weight allowance. Check your ticket, it usually shows what bags you can take on board, check-in and what are the weight limits.

Carry-ons for Business Travellers

If you are a business traveller going on very short trips, then a small or medium-sized cabin suitcase with a tech compartment will be perfect for you.

You should also consider an elegant travel backpack which will fit your electronics, especially if you don't need to carry clothes with you.

If you have to have clothes with you, check if packing cubes might be a good fit for you. They allow you to organize your clothes and, when packed well, prevent unwanted creases.

Suitcases for Digital Nomads

Depending on how often you change locations, a medium, or large checked luggage and a smaller carry-on suitcase or backpack should be enough.

Make sure to put your laptop, electronics, and batteries into your carry-on. It is never recommended to put valuables into checked-in luggage. Did you take out travel insurance?

As a digital nomad, you should travel light. If you move a lot, you will soon become an expert in packing and unpacking. Packing cubes can help you keep your stuff well-organized and easy to access.

If you are on a budget, consider buying a medium/large backpack. It is super convenient and easier to get around with it.

Luggage for Professional Travellers & Travel Bloggers

Depending on the length of your trip, I recommend you to purchase a medium or large checked bag and take a smaller carry-on with you for your papers and electronics.

Remember, never put valuables into checked-in luggage and always have insurance for your gear before travelling.

For short trips, we always take a small spinner suitcase and our Thule bag with us. The spinner can usually fit into the overhead lockers alongside the electronics bag. However, if we can only carry one bag on board, we simply check in the spinner. No worries.

Budget Travellers

If you are a budget traveller who doesn't want to pay for checked-in luggage, a large cabin suitcase will be perfect for you. Make sure you check with the airline that your suitcase size fits the allowed carry-on sizes and weight allowance.

Remember, that nowadays some airlines ask you to check in your luggage if you didn't purchase priority boarding.

It's always a good idea to keep a small handbag or a carry-on backpack with you which fits under the seat, so you can quickly remove valuables from your larger luggage.

For City Breaks & Couple Travellers

If you are going away for a quick city break or doing a multi-city hop for a few days (we are jealous) a medium suitcase should be enough. You can check it in or (in most cases) carry it on board.

A medium suitcase will usually fit clothes and accessories for two people for 2-4 days.

Need more space for gadgets and clothes? Pick a size larger suitcase and relax. You should always go for the four-wheel versions, as they are much easier to roll around.

Pro Tip: See if packing cubes can be a good fit for you. They are great to organize your clothes, inexpensive and will make your life much easier.

Holidaymakers

Travelling for 1-2 weeks? I would recommend one medium-sized suitcase per person (unless you are going to the beach or to a very hot destination, which case you really don't need much space).

If this is your first time purchasing suitcases, consider buying a suitcase set so you get better value for your money.

For your convenience, check-in all your luggage and keep just a small bag with you for your papers and valuables. This small bag should fit under the seat in front of you.

Long-term Travels & Couples

The medium or large suitcase is for long-term travellers or couples who want to minimize the checked-in costs. When you travel with someone, both of you have a carry-on bag to take on board and a checked bag each, so you have a lot of space to play with.

It's always better to travel light, but we understand that you need a lot of stuff when you travel long term. Remember to always check the size and weight allowances with your airline before you travel.

The extra-large suitcases are perfect for long-term travellers who spend a lot of time in one destination, or for expats moving countries. Airlines normally allow you to purchase additional checked bags if needed.

Families Travelling with children

We recommend the medium or large suitcase sizes for families with children. Purchase the four-wheel version so you can carry your suitcases around much easier.

Consider investing in a suitcase set, so you get better value for your money.

Don't forget to plan ahead. Make sure to pack everything you need onboard into a separate carry-on. Are you travelling long-haul? Consider taking food, water, medicine, toys for the kids, personal hygiene items with you.

Check with the airline to ensure, your carry-on is within the allowed size and weight limits.

It is a good idea to organize an airport shuttle to and from your hotel. This way, you will have to worry less about your luggage and enjoy more of your stay. Did you take out travel insurance?

Compare Carry-on Suitcase Sizes & Volumes

Ever wondered how much stuff you can actually fit in one of these carry-ons?

In this handy table, I have collected the measurements and volume of each airline-approved carry-on suitcase. Use the "Size Type" Column to find the airline list below.

Carry-on Suitcase Sizes for Various Airlines

Airline companies around the world have different requirements in terms of size and weight of your carry on luggage.

In the tables below, we have collected most major airlines and grouped them by their maximum allowed carry on size. For each airline, we added the allowed carry-on weight in kilogram and pounds.

Size A - Carry-on suitcase

Airlines listed below allow carry-ons no larger than 55x35x25 cm (21.6x13.8x9.8 inches) on board.

Size B - Hand luggage

Airlines listed below allow carry-ons no larger than 55x40x20 cm (21.6x15.7x7.9 inches) on board.

Size F - Various other sizes

Each airline listed below has a different carry-on policy. If you can't find your airline, please let us know in the comments section below which airline you are after, and we will add it.

Compare Checked-in Suitcase Sizes

Most airlines allow a checked-in suitcase to weigh between 20kg (44 pounds) to 25kg (55 pounds), but the checked-in baggage allowance varies so much that it is almost impossible to collect them all.

The absolute maximum weight of any check-in bag is 35kg for health & safety reasons. Any bag weighing more than 35 kg will be refused by the airline.

Your baggage allowance will depend on the airline, the length of your flight (short or long-haul), and occasionally the policy of the airport where you depart from.

Always check with the airline before you travel and allow yourself enough time to pack your bags before you leave.

In the below table, we have collected the different sizes, capacity and recommended travel times for each checked suitcase size.

The below image shows the sizes of different suitcases.

How much does extra baggage cost?

If you are taking extra carry-on luggage with you onboard or check an extra suitcase on the plane, you might have to pay an 'excess baggage fee'.

The excess baggage charge can significantly vary between airlines. Excess carry on fees are normally lower than excess checked-in luggage. Also, keep an eye on potential extra fees. For example, if your extra luggage is also oversized (it's larger than the permitted checked-in luggage size) you might need to pay additional charges on top of the excess baggage fee.

It's best to check with the airline prior to your travel.

Tips & Trick we learnt during our travels

Always go for the four-wheel suitcases

Suitcases are normally inconvenient to carry around. Always purchase the four-wheel version of larger suitcases. These are easier to roll, and you don't have to lift them up.

Keep an eye on the quality. If the suitcase is of bad quality, you risk the wheels being broken by the time you arrive at your destination. Check the reviews and try to go for the suitcase with the most indented wheels.

Less is more

We found that it's sometimes better to carry one large suitcase with us instead of two or three smaller ones. However, always make sure not to overfill your suitcase and check the weight before you travel.

Make sure you are comfortable pulling and lifting the suitcase yourself.

Carry your valuables with you at all times

Unfortunately, it can happen that things disappear from your checked baggage. We recommend that you never put valuables into the bags you check-in. Keep a small bag with you and put all your papers, electronics, and valuables in there.

Hardshell vs soft case

We found that during long-haul we prefer a good, sturdy, hardshell suitcase. The hard shell will protect your items in the suitcase and won't tear or damage during handling.

Soft cases are lighter normally and easier to carry when you go for a short trip. Wrap fragile items in t-shirts and jumpers, so they survive the trip.

Travelling with batteries & drones

Regulations on bringing batteries on board (in a carry-on or checked baggage) varies from country to country and from airport to airport. Find the European regulations here, USA regulations here.

Most airlines and airports require you to carry the batteries with you on board in your carry-on. The batteries will be checked during security.

Some airports (we are looking at you Budapest Airport) might not allow you to carry drones on board in your carry-on. You will have to take any batteries out of the drone and place them in your carry-on separately.

Always check the regulations before you leave for both your origin and destination countries. If you transfer to a new flight, make sure to check the policy of the transfer airport & country too.

Your drone and batteries can be confiscated if you don't comply with regulations.
