Largest suitcase size

If you're looking for the largest suitcase size, you'll usually end up with an extra-large checked luggage suitcase that's about 77 to 87 cm tall and has a capacity of 90 liters or more. Some models even go up to 130 to 144 liters. This size is especially handy for long trips, family vacations, or when you simply want to pack a lot.

However, the largest size isn't necessarily the smartest choice. The external dimensions, the empty weight, and your airline's baggage policies also matter. A large suitcase that's too heavy or too big may result in additional fees when you check it in.

When do you really need an extra-large suitcase?

The largest suitcase is especially practical if you're going away for an extended period or packing for several people. Think of a three-week road trip, a long-distance vacation, a winter destination that requires warm clothing, or a family trip where you'd rather use one spacious suitcase than two smaller ones. In that case, you might also want to consider luggage sets that include a large suitcase.

• For trips lasting about 3 weeks or longer
• For families who want to pack their luggage together
• For bulky items such as coats, shoes, and toiletries
• For those who want extra space without having to bring multiple suitcases

If you're only going away for a few days, the largest suitcase size is often unnecessarily big. You end up taking extra space with you without really using it.

Here's how to quickly compare suitcase sizes

Can't decide between medium, large, and extra-large? With this suitcase size guide, you can immediately see where the largest size fits within the standard suitcase sizes.

How big is the largest suitcase in centimeters and liters?

In practice, the largest suitcase size usually refers to a suitcase measuring 77 to 87 cm. The capacity often starts at around 90 liters and, for extra-spacious models, can exceed 100 liters. This gives you enough space for longer trips or for luggage for several people. Want to know how this compares to 25 kg of luggage? Then read “25 kg suitcase: how many liters?”

Pay close attention to how the dimensions are measured. Online stores and brands usually include wheels, handles, and other protruding parts in the total exterior dimensions. This is important because airlines look at the actual exterior dimensions and total weight, not just the number of liters.

What are the maximum dimensions for a suitcase?

There is no universal maximum size for a suitcase. Each airline determines its own size and weight limits covered by your ticket. For checked baggage, these limits are usually a combination of external dimensions and weight. Therefore, always check your airline’s rules before booking or packing.

Is a 100-liter suitcase considered large?

Yes, 100 liters is definitely a large suitcase. This size is ideal for a longer vacation or a trip where you’ll be packing multiple outfits, shoes, or heavier clothing. Just keep the weight in mind: a 100-liter suitcase fills up quickly, but it also adds up to more weight than you might think.

What size suitcase is suitable for 23 kg?

23 kg refers to the weight limit, not to a specific suitcase size. In practice, 23 kg usually works best with large suitcases (Large) measuring approximately 75 to 87 cm and holding roughly 90 to 120 liters. This gives you plenty of space without having to go straight for the largest size.

Still, 23 kg is a matter of personal choice. Heavy items like shoes, books, and toiletries fill up the weight allowance faster than light summer clothing. So don’t just look at the capacity in liters—also consider the empty weight of the suitcase itself. A lightweight yet sturdy model leaves you with more usable kilograms for your luggage.

How many kilograms does a 79-liter suitcase weigh?

A 79-liter suitcase usually falls into the medium-to-large category. As a rough estimate, you can expect about 15 to 20 kg of usable capacity, depending on what you pack. Lightweight clothing often takes up less space, while heavier items can quickly increase the weight. So while 79 liters can be spacious, it isn’t automatically meant to hold up to 23 kg.

What should you look for when choosing the largest size suitcase?

When it comes to an extra-large suitcase, it’s not just about maximum capacity. It’s these features that make all the difference in terms of comfort and ease of use:

• External dimensions, including wheels and handles
• Empty weight, so you have more of your allowed weight left
• Four smooth-rolling wheels for stable and comfortable maneuvering
• A sturdy exterior for use in the hold
• A well-organized interior with compartments, straps, or dividers
• A TSA lock if you want extra convenience and security when traveling by plane

That way, you're not just choosing the largest size, but—more importantly—a suitcase that's comfortable to travel with and fits your packing style.

Frequently Asked Questions

Is the largest suitcase always the best choice?

No. The largest size is mainly a good choice if you actually need that much space. For short trips, a smaller size is often more convenient, lighter, and easier to carry.

Can the largest suitcase size be carried on as carry-on luggage?

No, an extra-large suitcase is intended for check-in luggage. Carry-on suitcases are subject to much smaller size limits, usually around 55 cm in height, depending on the airline.

When do you have to pay extra for a large suitcase?

This usually happens if your suitcase is heavier or larger than what is allowed under your ticket. The rules vary by airline, route, and the type of baggage you booked.

How do you measure a suitcase correctly?
