Does your carry-on fit?
Type the outside of the bag, wheels and handles included. The checker tells you which published carry-on and personal-item limits those numbers meet. It is not a promise from the gate agent.

19 airlines. US limits are compared in inches. Airlines that lead with centimeters are compared in centimeters, because their inch conversions are rounded. A miss of 0.2 inch or less is marked borderline.
How the checker decides
Each airline limit is a box, a linear sum, or both. Your three measurements are sorted largest to smallest and compared with the airline's three sides sorted the same way, so a bag entered as depth first still matches a bag entered height first. A side that misses by 0.2 inch or less is marked borderline, because wheels, tags, and rounded centimeter conversions live in that gap. Anything more is over.
Weight is optional. If an airline publishes no carry-on weight, the weight field says so instead of inventing a cap. Air France and KLM publish a combined cap for the cabin bag and the small bag. Frontier publishes 35 pounds. Emirates, Qatar, and Singapore publish 7 kg on the cabin bag. Leave weight blank and the size result still runs.
Personal items are a second column. Delta, Southwest, and Alaska did not publish length × width × height on the pages we used, so those rows refuse to pass or fail a personal item. Emirates and Qatar Economy publish one bag, not a second personal item.

What this does not know
- Regional jets can force a valet or a gate check even when the bag fits.
- A soft bag grows when it is full. The number you type should be the packed bag if that is how you travel.
- An expanded zipper is a larger bag. Measure it expanded if you plan to expand it.
- We did not put these suitcases in a sizer. Presets use the Amazon listing's published overall size.

Questions people ask next
Does this use the airline sizer or the marketing size?
You type the outside of the bag, including wheels and handles. The tool compares those three sides, in any order, with the box each airline publishes. It does not know if your bag is overstuffed.
Why can a bag fit the carry-on box and still cost a fee?
United Basic Economy, Spirit Value, Frontier, Allegiant, Ryanair, easyJet's large bag, and several European light fares do not include a full carry-on. The fare note is separate from the size result.
What if the airline prints both inches and centimeters?
US airlines are scored in inches, because the sizer is in inches and the centimeter line is often rounded. Airlines that lead with centimeters are scored in centimeters.
How current are the limits?
Each row links to the airline page we read. The set was last checked on November 10, 2026. Airlines change fares more often than they change the box.
