How Many Liters Is a Large Suitcase?
How many liters is a large suitcase for checked baggage and airline luggage?
When people ask how many liters a large suitcase is, they usually want a quick number they can trust before booking a flight or starting to pack. In our range, the “large suitcase” question is best answered by looking at the exact suitcase size and intended luggage type because our collection includes a 36-liter cabin bag and a larger checked luggage option. So, if you are searching how many liters a large suitcase is, the most useful approach is to match liters to the dimensions we actually sell, not a vague category label. If you are also trying to confirm cabin dimensions, this guide on what size is a cabin suitcase helps you align suitcase size with typical airline rules.
Suitcase size guide: our cabin suitcase vs. checked luggage
If you want a reliable luggage size guide, start with the two adult sizes we offer and treat them as your baseline. The cabin bag suitcase is 55 × 35 × 25 cm and is designed for cabin luggage and hand luggage restrictions while still being a tough, hard-sided carry-on. The medium option is 67 × 43 × 25 cm and is intended as checked baggage for longer trips where you need more clothing, shoes, or bulky items. Both are polycarbonate hard-shell suitcases with 360° spinner wheels and an integrated TSA lock, so the main difference is suitcase size and how much you can pack.
Because you are asking about liters, note that we state the cabin bag capacity clearly: 36 liters. For the larger checked luggage suitcase, airlines focus more on size and weight restrictions than an exact liter number, so you should use the dimensions as your main reference. This is also why a suitcase size guide is more useful than guessing “large suitcase liters" from generic charts. If you are planning around weight, you may also find what size suitcase for 23kg helpful as a practical packing reference.
Choose a large suitcase: airline baggage allowance, size limits, and maximum size
Answer first: To choose a large suitcase for a flight, match your suitcase size to your airline luggage allowances and your baggage allowance, then consider how long you are traveling. Many travellers call any checked bag “large,” but a specific airline may set different size limits and weight rules, so it is smart to check with your airline before you fly. Your allowance can also change by route, ticket type, or status, which is why airline luggage rules matter more than a single liter figure. Keep in mind that airlines typically measure the outer suitcase dimensions, including the shell and wheels, when applying luggage size restrictions.
With our range, the cabin suitcase is built to fit common cabin size expectations at 55 × 35 × 25 cm, and it is widely accepted as carry-on by almost all carriers. For checked baggage, our 67 × 43 × 25 cm suitcase gives you a roomy option that still stays practical to handle at the airport. If you need to make the right suitcase size decision, think about trip length, footwear, and whether you will bring gifts home. If you are ever unsure about maximum size limits for checked baggage, use your airline’s published chart and compare it directly to the suitcase measurements you plan to take.
Hard-shell polycarbonate luggage with TSA: what it means for security and durability
Both adult suitcases in this collection are hard-shell suitcases made from polycarbonate, which is known for being lightweight and resilient. A hard-shell design helps protect your belongings when your checked baggage is handled, stacked, or moved across different airport surfaces. Each suitcase includes a TSA-approved lock, which is useful when traveling internationally and reduces the risk of damage during inspections. The result is hard-sided luggage that feels sturdy without being awkward to roll or lift.
Security is not only about the lock but also about how the suitcase closes and holds up over time. Our suitcases use a secure zip closure, and the shell construction is designed for repeated travel. If you ever need help after setting your code, this guide on how to reset a suitcase lock walks you through the steps. That way, your luggage stays both secure and easy to use, trip after trip.
Spacious, roomy packing: main compartment and packing cubes
Answer first: The most “spacious” suitcase is the one that matches your trip and opens in a way that keeps everything organized, and our designs are built with that in mind. A well-planned main compartment makes it easier to separate outfits, toiletries, and shoes without everything shifting. Using packing cubes can make a cabin bag feel surprisingly roomy, and it also helps you stay organized when you arrive and repack quickly. This matters whether you are using carry-on for a short break or checked luggage for a longer holiday.
For the 36-liter cabin bag, smart folding and cubes help you maximize space while staying within hand luggage restrictions. For the larger checked baggage suitcase, you have more flexibility for extra layers, sportswear, or souvenirs, and the hard-shell structure helps keep the suitcase's shape consistent. If you like to keep smaller items accessible, note that soft-shell suitcases and soft-sided luggage often rely on external pockets, while our adult range focuses on a clean hard-shell build. For a step-by-step method, see how to pack a suitcase and adapt it to the suitcase size you are traveling with.
Which suitcase for which trip?
Our collection is designed so you can choose a suitcase based on who is traveling and how. Adults often start with the cabin bag suitcase at 55 × 35 × 25 cm and 36 liters for short trips or tight airline luggage rules, then move up to the medium suitcase option at 67 × 43 × 25 cm for longer travel and checked baggage needs. For families, our kids' luggage range adds child-friendly sizes and materials so children can manage their own suitcases more easily. This makes packing and moving through the airport simpler, especially when everyone has their own luggage.
We offer multiple kids' suitcase options: a small kids' suitcase of 31 × 19 × 48 cm and a hand-luggage kids' suitcase of 55 × 35 × 25 cm in polycarbonate, plus a 46 × 31 × 19 cm kids' case made from transparent PVC and polyester. The kids' suitcase includes two wheels with lights for visibility and fun, plus an adjustable pull handle and an extra carry handle. This is a practical choice when you want a lightweight suitcase that children can pull themselves. If you are unsure about items like chargers or grooming tools, do electrical items go in hand luggage or a suitcase can help you decide what goes where.

Our cabin suitcase holds 36 liters and measures 55 × 35 × 25 cm. It is designed to meet common airline carry-on expectations, but always compare it with your airline’s rules.
Our checked baggage suitcase is not described as expandable, and it uses a secure zip closure with a hard-shell build. If you need extra capacity, choosing the larger suitcase size is usually a better solution than relying on expansion.
Hard-shell suitcases can offer stronger protection for items during handling, especially in checked baggage. Soft-sided luggage can be useful for external pockets, but our focus is on hard-sided durability and security.
There is no single 23kg suitcase size because airlines apply different size and weight restrictions. Use your airline’s allowance and compare it to the suitcase dimensions you plan to check in.
