Measure the bag’s full outside height, width, and depth—including wheels, handles, pockets, and other protrusions—then compare each dimension with the operating airline’s carry-on rules. If the airline also sets a combined linear-inch limit, add the three measurements; when available, check the bag in the airport sizer, especially if it is close to the limit.
How to measure a carry-on bag
-
Empty the bag and stand it upright on a flat floor. Close the expansion zipper for a baseline measurement, but leave fixed pockets, wheel housings, handles, and trim in place. A useful measurement guide recommends checking the bag in the configuration you expect to take to the gate: carry-on measurement method.
-
Measure height from the floor to the bag’s highest fixed point. Include wheels and the handle housing; also count a handle that does not retract or fold flat. Delta, JetBlue, and American explicitly include wheels and handles in their published dimensions (Delta; JetBlue; American Airlines).

-
Measure depth from front to back at the thickest point, including wheel housings and front pockets. If you plan to travel with the expansion zipper open, measure the expanded bag too.
-
Record the result as height × width × depth, keeping the axis labels. Airlines may list dimensions in different orders: Air Canada, for example, uses depth × width × height. A rigid tape measure can be easier to hold against a curved shell than a soft tailor’s tape, according to the measurement guide (measurement tool guidance).

Check the airline’s actual limit
Look up the carry-on allowance for the airline operating your flight and fare, not just the airline whose name appears on your booking. Compare height, width, and depth separately. A combined linear-inch maximum does not override a separate limit on any one side.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsThe Federal Aviation Administration explains that 45 linear inches means height + width + depth and says most airlines use that maximum; it also directs passengers to check their airline’s requirements. The FAA does not establish one universal carry-on size. Its Carry-On Baggage Tips page advises: “Check with your airline before packing to determine its carry-on guidelines regarding the number of items you may carry on and the maximum size of those items. Some airline rules are stricter than posted regulations.”

Carry-on rules are not the same as personal-item rules for under-seat storage. Check the correct category for your bag. For flights involving partner airlines, Air Canada says another carrier’s policy may apply when it operates the flight. A secondary comparison dated September 27, 2026, found differences among seven U.S. airlines in size, fare allowances, and weight rules; verify details directly with the carrier (Flightfare’s airline comparison).

Use a sizer if the bag is close
Compare your measurements with the published limits, then use an airport bag sizer where available. American requires the carry-on to fit its airport sizer, and Air Canada describes automated baggage sizers. A close measurement can be affected by bulging fabric, how the bag is packed, or measurement uncertainty; test the bag in the shape you will present at the gate.

The FAA directs travelers to airline rules, and American notes that additional restrictions may apply at some airports and on some planes.
