Start with the most restrictive dimensions
A rigid suitcase does not compress in the template. If you use multiple companies, compare its external dimensions to each excess instead of relying on a format presented as universal.
The announced dimensions must include wheels and handles. Always check the official rule associated with your ticket before departure.
Empty weight directly reduces your payload
Subtract the empty weight from the limit applicable to your ticket to estimate the remaining margin. The result must include other bags if the carrier applies a cumulative weight.
However, lightness should not mask the quality of the wheels, telescopic handle and hull.
Hard shell, soft shell or zip-free closure
Each building brings a different compromise.
- A rigid shell better protects from pressure but retains its exact dimensions.
- A soft suitcase is more easily compressed and often offers an outdoor pocket.
- A dot closure avoids the main zip, at the price of a weight sometimes higher.
- An expansion adds capacity but may make the suitcase incompatible with the airline's size limit.
Pay only the benefits you will use
For any extra cost, look for a useful and documented benefit: reduced weight, warranty conditions, available parts or repair service.
A luxurious finish or a prestigious brand may please, but it is not enough to create a better value for money.

Frequently asked questions
Which cabin suitcase size should you choose?
The one that respects the dimensions of the baggage allowance of your ticket, with wheels and handles. No commercial format guarantees acceptance on all flights.
What weight should you aim for?
Compare the available margin after deducting the unladen weight, then examine portage, wheels and repair. The relevant threshold depends on your excess and content.
Does an expandable suitcase still meet the limit?
Not necessarily. Check the dimensions once the extension is open: a few extra centimetres may exceed the template.
