Many airlines are very helpful in their suitcase size restrictions. They offer dimensions and weight limits that can be checked before you arrive at the airport to help you ensure your luggage meets the requirements for travel.

However, sometimes you’ll be faced with less than helpful measurements. For example, you might be told that you can take a “small” or “medium” sized case, but what exactly does this mean?

A medium-sized suitcase could mean something different to everyone, but there is a generally accepted size range that would be considered “medium”. It’s typically a large cabin bag size, which is around H56cm x W45cm x D25cm. There might be some variation in this size.

For example, Samsonite considers a medium-sized suitcase to be between 60 to 69 cm tall and with a capacity of 50-120L. This is a huge variation, so you would be right to be confused.

How big is a medium-sized suitcase?

A medium-sized suitcase is still a compact size, but you might struggle to lift it if you pack particularly heavy items. It would typically be suitable for a one-week trip.

Many airlines will distinguish between a medium-sized check-in suitcase and a medium-sized carry-on suitcase. If you plan to take the suitcase on the plane, check the airline for more specific guidelines on the permitted size of your suitcase.

If you are checking in your suitcase, the size is less important than the weight. Your suitcase may be medium-sized, but it could easily exceed the weight limit. Always check with your airline before you travel to avoid any overweight penalties.

What is a medium-sized suitcase suitable for?

A medium-sized suitcase is a versatile case that can work for a wide range of trips. It would give ample room for a long weekend but could also extend to a week-long trip if you are selective about what you bring. A couple could share a medium-sized suitcase for a weekend trip.

If you choose a medium-sized suitcase with wheels, you’ll find it easier to get around. However, be wary about any times you might need to lift the case. For example, if you are travelling by plane, you might need to lift it into the overhead lockers. And if you are travelling by bus or train, you might need to navigate steps and stairs with your suitcase.

How can I find out size limits before travelling?

The best thing to do if you are unsure about the size requirements for your trip is to contact your travel provider. This could be an airline, bus service or train operator. Always confirm before you travel that your suitcase will be accepted on your trip.

This will allow you to make adjustments to the case if needed and bring a smaller case. It might also reveal that you can bring a much larger case than anticipated, which can make life easier when packing. 

However, remember the overall weight of the case will have a big impact on your enjoyment once you are travelling, particularly if you have to carry it up stairs or navigate city streets with it.
