Allowances are the published economy-class figures for a standard fare and are reviewed by hand, but airlines change them often and low-cost carriers tie the bigger cabin bag to a priority or bundled fare. Always confirm on your airline's own baggage page before you fly.
How it works
Enter the length, width and depth of your suitcase — measured at the widest points, including wheels, handles and side pockets, because that is what an airport bag sizer measures — and the checker compares it with the cabin baggage allowance of 52 airlines. A bag fits a sizer only if it can be slid in flat, so the check sorts your three measurements from largest to smallest, sorts the airline's three limits the same way and requires every pair to pass. That means orientation does not matter: a 55 × 40 × 20 cm bag is treated as identical to a 20 × 55 × 40 cm one, exactly as an airport gauge would. Add a weight and airlines with a kilo limit are checked too, so you can tell "too big" apart from "too heavy".
Switch to Personal item / underseat to test the small free bag instead, and use the region filter or search box to narrow the list. The tool also adds your three measurements together: the total linear size is what nearly every airline uses for hold luggage, where 158 cm (62 in) is the near-universal ceiling before oversize fees start. Metric and imperial inputs are interchangeable — everything is converted for you. All of it runs as plain JavaScript in your browser with the airline data embedded in the page: no uploads, no sign-up, no ads and no network requests.
Frequently asked questions
What is the maximum carry-on size?
There is no single global rule, but 55 x 40 x 20 cm (about 22 x 16 x 8 in) clears most airlines, and the widely quoted IATA guideline is 56 x 45 x 25 cm. Weight is the bigger trap: European and Asian carriers usually cap the cabin bag at 7-10 kg, while most US airlines set no weight limit at all. Enter your measurements above and the checker shows which of the 52 listed airlines accept the bag and which reject it for size or weight.
Do I have to include the wheels and handles when measuring?
Yes. Airport bag sizers are rigid boxes, so everything that sticks out counts: wheels, telescopic handle housings, side pockets and bulging straps. Measure the widest point in each direction with the bag packed, not empty, because a soft-sided case grows once it is full. The checker sorts your three measurements and the airline's three limits from largest to smallest and compares them pairwise, which is exactly what a sizer enforces — orientation does not matter, but every dimension has to pass.
What size bag can I check into the hold without an oversize fee?
Nearly every airline uses total linear size for hold luggage: length plus width plus depth. The near-universal ceiling is 158 cm (62 in), and a typical large 75-80 cm suitcase lands just under it. The tool shows your bag's linear total and how much room is left before the oversize surcharge, which is usually charged on top of any excess-weight fee.
