Cabin bag size checker: will your bag fit?
Type your bag's size, in centimetres or inches. We check it against 33 airlines and trains in the UK, Europe, the US, Canada and Australia: free under the seat, cabin bag included in your fare, paid extra, or refused. Limits read on each airline's official site on 1 October 2026.
Your bag
Measure it packed, including wheels, handles and pockets: that is what the sizer at the gate measures. The order of the sides does not matter.

US and Canada: carry-on sizes

Three things that cost people a gate fee
- The "free" bag is not the same size everywhere. A 20 cm-deep backpack is a free under-seat bag at Ryanair and easyJet, but too deep for British Airways, Air France or KLM's 15 cm personal item.
- Weight is often shared. Transavia and Volotea cap both items at 10 kg together; Air France and KLM at 12 kg; Jetstar and Qantas international Economy at 7 kg.
- "Cabin bag" does not mean "included". Ryanair, Frontier and Wizz Air sell the overhead bag as an extra on their basic fares; United Basic Economy and WestJet UltraBasic leave it out on most routes.
