Carry-on & personal item size checker

Yes. Measure the outside of your fully packed bag at its widest points, including wheels, handles, feet and pockets. A manufacturer's shell dimensions may leave these out.

This checker compares the three sides from longest to shortest, which tests rectangular rotation. It does not assume you can compress an overfilled bag. Where the airline publishes individual sides, each side must fit. A published total-size cap must also be met. For airlines publishing only a total-size cap, meeting that total still requires confirming the bag can be stowed.

An exact match fits the published dimensions with zero spare room. A small measuring error or bulging pocket can change that result. Displayed margins are rounded to three decimals, but the calculation uses unrounded values with no physical tolerance.

No. Overhead bags can require a paid option. Choose the entitlement actually shown on each booking. The checker reports fare entitlement separately from size and weight, including when a bag fits but the selected option does not include it.

Add every operating airline, including the return flight, up to eight flights. You see a result for each leg and the strictest set of dimensions. The checker does not apply one carrier's allowance to a partner or assume that checked-baggage through-ticket rules apply to cabin bags.

A blank packed weight leaves weight unassessed. Where bags share a weight cap, enter the weight of all other cabin items too (0 if none). A missing numeric cap or missing other-item weight is never counted as a pass. Confirm flight-specific rules with your airline.

Your result includes a repacking plan: which sides to reduce, by how much, which flights set those limits, and how much weight to remove. It summarizes published side and total-size limits, and flags any missing measurements that need airline confirmation. A rigid bag needs to be replaced if its shell is too large; the checker never assumes compression.

After checking your bag, compare the same measurements across all supported airlines, with weight checks and the required baggage options shown separately. Overhead results also check whether the same bag fits the personal-item limits on your selected flights. You can switch to a full personal-item check without re-entering measurements.

Some airlines publish only an underseat-fit requirement, without measurements. Wizz Air also has a handle/wheel exception that cannot be decided from outside dimensions alone. These cases are marked for confirmation instead of inventing dimensions or giving a false pass.
