How this checker compares your bag
Type your bag's length, width and height in any order — the checker sorts your bag's three sides and each airline's three limit sides from longest to shortest and compares them side by side. That way it doesn't matter which side you call "length" versus "height".
Most airlines measure the bag as it will be carried onto the plane, including any handles and wheels — a bag that only fits the limit with the handle pushed down or the wheels removed will usually still be flagged as too big at the gate.
When this data was collected
Figures were checked against each airline's own baggage page in August 2026. Airlines change carry-on rules often, including by route, fare class, and elite status — always confirm on the airline's own site before you fly.
What this checker does not cover
It only checks the one carry-on bag you can bring into the cabin. Most airlines also allow one smaller personal item (a purse, laptop bag, etc.) under a separate, smaller limit that this tool does not check. It also does not cover checked baggage or route-specific exceptions.
How do I check if my bag is carry-on size?
Measure your bag's three sides and its weight exactly as you'll carry it onto the plane, handles and wheels included. Compare your longest side to the airline's longest allowed side, your middle side to their middle side, and your shortest to their shortest — if all three fit and your weight is under any stated limit, your bag is within that airline's carry-on allowance.
Steps to check your bag against an airline's limit
- Measure length, width and height in centimeters (or inches), including handles, wheels, and any external pockets.
- Weigh the bag as you'll actually carry it, packed.
- Sort your bag's three measurements from longest to shortest.
- Sort the airline's three limit measurements from longest to shortest the same way.
- Compare the two sorted lists side by side, and check your weight against the airline's stated weight limit, if any.
The size comparison, in one line
Fits = (longest side <= airline's longest limit) AND (middle side <= middle limit) AND (shortest side <= shortest limit)
- sides are compared by rank (longest-to-longest, shortest-to-shortest), not by a fixed length/width/height label, since bags can be turned to align with the sizing frame
- weight is compared separately — a bag can pass on size and still fail on weight, or vice versa
Example: does a 54 x 36 x 22 cm, 9 kg bag fit?
| Airline | Limit (L x W x H) | Weight limit | Result |
|---|
| Southwest Airlines | 61 x 41 x 25 cm | no stated limit | Fits |
| Air Canada | 55 x 40 x 23 cm | no stated limit | Fits |
| ANA | 55 x 40 x 25 cm | 10 kg | Fits |
| Delta Air Lines | 56 x 35 x 23 cm | no stated limit | Too big (+1 cm on size) |
| Emirates | 55 x 38 x 22 cm | 7 kg | Too big (+2 kg on weight) |
| Wizz Air (free bag) | 40 x 30 x 20 cm | 10 kg | Too big (+14 cm on size) |
Frequently asked questions
Do carry-on size limits include the handle and wheels?
For almost every airline in this checker, yes. The published dimensions are the outer size of the bag as it's carried onto the plane, wheels, handles, and side pockets included, not the size of the empty shell without hardware.
Does it matter which side I call "length" versus "height"?
No. This checker sorts your three measurements and each airline's three limit measurements from longest to shortest and compares them in that order, so the labels you use don't change the result — only the three numbers do.
Is the personal item the same as the carry-on bag?
No. Almost every airline treats them as two separate items with two separate, smaller limits for the personal item (like a handbag or laptop bag). This tool only checks the larger carry-on bag.
Why does one airline show "no stated weight limit"?
Some airlines, including several full-service US carriers, only publish size limits for carry-on bags and rely on the bag fitting the overhead bin sizer instead of a hard weight cap — though staff can still ask you to check a bag that seems too heavy to lift.
Why do budget airlines have such small free-bag limits?
Many low-cost carriers only include a small, personal-item-sized bag for free and charge extra for a larger cabin bag with a bigger size allowance. Check the airline's website for its paid options if the free size is too small.
This checker compares your entered dimensions and weight to each airline's published general economy carry-on policy; it does not know your specific fare class, route, elite status, or aircraft type, all of which can change the real limit. Gate staff make the final call, and a bag that is technically within the published limit can still be asked to be checked if the overhead bins are full. Airlines change these policies often — always confirm on the airline's own site close to your travel date.
