Does my bag fit? Cabin bag size checker for 28 airlines (2026)
Enter the three sides of your bag and see which airlines accept it free with every fare, which only with some fares or as a paid extra, and where it is too big. The sizes come from each airline's official page, quoted on the airline pages with the date we checked them.
How we compare: sides sorted from longest to shortest on both sides, so a 20 x 40 x 30 cm bag counts as 40 x 30 x 20 cm. An airline may measure in a fixed position (for example height x width x depth, or in its sizer) and may weigh the bag: the airline's official rule decides, not this page. In inches we use the airline's own inch figures where it publishes them, otherwise its centimetre figures (1 in = 2.54 cm). Where an airline publishes inches only, the centimetres shown with “≈” are our conversion.
Airlines change their bag rules and measure bags their own way (usually in a sizer at the airport, with wheels and handles). We quote each airline's official page on the date shown; the official rule and the airline staff decide. Check your booking before you fly.
