Enter your bag's 3 measurements in inches or centimeters, including wheels and handles. We check them against the carry-on and personal item size at 110 airlines and show where your bag fits. Every result links to that airline's full baggage page, with the date we last checked it.
3 measurements are all the checker needs. It sorts your numbers by size and compares each one with the airline's limit, so it does not matter which side you call length. Your bag fits only when all 3 are at or under the limit. Singapore Airlines and Asiana publish a 115 cm total instead of length, width and height, so those carry-on rows say No size published.
1 tape measure and a packed bag give you the numbers airlines use. Stand the bag upright and measure from the floor to the top of the folded handle for the length. Measure the width across the widest point, including side pockets, and the depth from the back of the wheels to the front pocket. For a soft bag or backpack, measure it full.
22 x 14 x 9 in (56 x 36 x 23 cm), the usual US carry-on size, is 1 cm too long for the 55 cm limit at Lufthansa, Aer Lingus, Air France and most European airlines. A bag bought for US flights can fail a European sizer, and a bag bought in Europe can be too wide for Delta, United and American. Asian and Gulf airlines often add a 7 kg (15 lb) weight limit as well.
1 cm over the limit gives a Too big result, because the checker uses the exact size each airline publishes. Fits means every measurement is at or under that airline's published limit. No size published means the airline gives no dimensions for that bag, so it only has to fit under the seat or in the bin. Click any airline to see its full carry-on rules and fees.
55 x 40 x 20 cm (21.5 x 15.5 x 8 in) is the size many cabin suitcases are sold in, and it fits as a carry-on at most European and Asian airlines. The table shows popular bag sizes and some of the airlines that accept them. Enter your own bag above for the full list.

2 cabin bags are allowed on most full-service fares: a carry-on for the overhead bin and a personal item for under the seat. The checker tests your bag against both limits. If it fits only as a personal item, you can fly with it on the cheapest fares at Ryanair, Wizz Air, easyJet and Frontier, where the overhead bag costs extra.
No. 22 x 14 x 9 in (56 x 36 x 23 cm) fits at Delta, United, American and most US airlines, but it is 1 cm too long for the 55 cm limit at Lufthansa, Air France and most European airlines.
50 x 35 x 20 cm (19.7 x 13.8 x 7.9 in) fits the overhead limit at every airline we track. Keep the bag under 7 kg (15 lb) for many Asian and Gulf airlines, and under 5 kg for Air China economy.
Yes, at Ryanair and Wizz Air, which both allow 40 x 30 x 20 cm under the seat. It is 5 cm too deep for the 40 x 30 x 15 cm limit at Lufthansa, British Airways, Air France and KLM.
Yes, on easyJet, where 45 x 36 x 20 cm is the free under-seat bag on every fare. It is too big for Ryanair's free 40 x 30 x 20 cm bag, so there it counts as a paid cabin bag.
Yes. Delta, American, United, Southwest, British Airways and easyJet all include wheels and handles in their size limits. Enter the outside size of the packed bag into the checker.
110 airline limits feed the checker, each taken from the airline's own website and shown with the date we last checked it. Gate staff make the final call, so measure carefully and check the airline page before you fly.
