Suitcase Size, Weight & Capacity

Suitcase Size, Weight & Capacity Guide

Picking a suitcase size mostly comes down to two things: how long you're going for, and how much of a packer you are. (We won't judge.) Here's how our sizes compare.

You'll find the exact measurements for every case on its product page.

Taking a cabin case?

Every airline has its own idea of what counts as cabin size, so it's worth checking yours before you fly. To make it easier, our cabin luggage by airline guide shows which of our cases fit each airline's limits.

How we measure

We measure the outside of each case at its widest point, wheels, handles and all. That's how airlines measure too, so there are no surprises at the gate. All measurements are approximate.

We don't list internal dimensions. Capacity, shown in litres, is the easiest way to compare how much each case holds.

Need a bit more room?

Our expandable suitcases unzip for extra space, which is handy for the trip home. Just bear in mind that an expanded case may be too big for airline limits.

What size suitcase do I need for a 20kg or 23kg allowance?

Your airline’s allowance is the total weight of your suitcase and everything packed inside it. Litres tell you how much space a case had, rather than how much it will weigh when full. Choose a size that suits your trip, then make sure to weigh your packed case before you travel.

Easy to store

When you're back home, cases from the same collection tuck inside each other like Russian dolls. A Holiday Cabin fits inside a Holiday Medium, which fits inside a Holiday Large.
