Choosing a cabin suitcase: dimensions, wheels and smart buying decisions

A cabin suitcase may seem easy to choose: pick a compact model, pack your things and set off. But problems often only arise at the airport. The suitcase turns out to be a few centimetres too big, its weight takes up too much of your baggage allowance, or the wheels are less practical than you expected.

As Joybuy Product Recommendation Officer, I start by looking at verifiable specifications. Not big marketing claims, but dimensions, weight, material and how you plan to use the suitcase.

Three common pitfalls when choosing a cabin suitcase

1. “Cabin size” isn’t universal

Airlines have different rules. For example, a cabin suitcase for Ryanair may be subject to different requirements from one for easyJet. Allowances and permitted dimensions can also vary depending on your ticket type.

Always check:

  • the maximum height, width and depth;
  • whether wheels and handles are included in the measurements;
  • the maximum weight;
  • whether the suitcase needs to fit in the overhead locker or under the seat;
  • the latest rules for your flight.

A product listing may say that a model is suitable for certain airlines, but you should still check with the airline.

2. A low weight doesn’t tell you everything

A lightweight cabin suitcase is handy because it leaves more room for clothes and electronics. But consider the balance between weight and construction. A soft suitcase weighing 1,46 to 1,7 kg can be comfortable to carry, while a hard-shell suitcase often offers more structure and protection but is also heavier.

As well as weight, look at:

  • the material, such as polyester, ABS, polycarbonate or ABS+PC;
  • how sturdy the frame is;
  • the quality of the zips and telescopic handle;
  • the maximum load for the wheels and handle.

3. Four spinner wheels aren’t always more practical

A suitcase with spinner wheels can move smoothly in multiple directions. That’s useful in a departure lounge or along a narrow shopping street. Two wheels often roll more efficiently behind you and may take up less space underneath the case.

With either system, check the wheel housing, how the wheels are attached and the surfaces you’re likely to travel on. “Silent” and “smooth” are descriptions used in product information, not a guarantee of performance on every surface.

Which specifications should you compare?

Dimensions: measure the outside

A 20-inch suitcase is often intended for short trips, but the label tells you less than the exact external dimensions. A model measuring 55 × 40 × 20 cm will fit differently from a suitcase measuring 56,5 × 37,5 × 23 cm.

Always compare the full dimensions. Also bear in mind:

  • protruding handles;
  • wheels and protective edges;
  • a front pocket that may affect the depth;
  • any expansion zip.

On some models, the internal dimensions may differ from the external dimensions by around 1 to 2 cm.

Hard or soft cabin suitcase?

A hard-shell cabin suitcase made from ABS, polycarbonate or ABS+PC has a rigid shell. This can be useful if you’re carrying fragile items or your suitcase is often moved around. A hard shell may be less easy to squeeze into a tight luggage compartment, though.

A soft cabin suitcase made from polyester is often more flexible and usually has an exterior pocket. This is handy for a passport, tablet or boarding pass. Its contents are generally less protected from pressure on the outside. Choose based on how you pack, not just on looks.

TSA lock and compartments

A suitcase with a TSA lock can be opened by authorised security staff using a special tool. The lock won’t stop someone from picking up the suitcase, or fully protect its contents. It’s mainly an extra locking feature for journeys where luggage may be inspected.

Also look for:

  • straps to secure your clothes;
  • a mesh pocket for small items;
  • a fully opening front;
  • a laptop compartment for business trips;
  • separate compartments for shoes or damp items.

Frequently asked questions about cabin suitcases

Which cabin suitcase is suitable for Ryanair or easyJet?

It depends on your ticket and the latest baggage rules. Compare the suitcase’s external dimensions with the allowance for your booking. A model described on its product page as suitable for several airlines may still not be permitted with a different fare.

How long does a cabin suitcase last?

Its lifespan depends on how it’s used, the surfaces it’s wheeled over, how heavily it’s packed and how well it’s maintained. Don’t exceed the maximum load for the handle or wheels, and avoid abrasive cleaning products. Wipe it with a soft cloth and check the zips and wheels regularly to spot wear and tear.

How much does it cost to maintain a cabin suitcase?

Routine maintenance costs very little: empty the suitcase after a trip, remove dirt with a soft cloth and check the wheels and zips. Spare parts such as wheels or a handle aren’t available for every model. Check the seller’s warranty and service information before you buy.
