About the Carry-On Size Checker
Every airline publishes its own carry-on (hand luggage) limits — usually a maximum length, width, and depth in centimetres or inches, and sometimes a weight cap. The frustrating part: those limits are not consistent. A bag that breezes through gate inspection on Delta may be flagged at the boarding gate on Ryanair, Emirates, or Singapore Airlines. This tool checks your bag's dimensions against the published limits of 40+ major airlines worldwide — North American carriers, European flag carriers, Asia-Pacific airlines, Middle Eastern carriers, and low-cost airlines — so you know before you pack whether your bag will fly.
Dimensions are compared against each airline's largest allowed measurement, regardless of how you oriented the bag. If a weight limit applies and you've entered a weight, that's checked too. Wheels and handles count toward the total — measure them in.
How to Use the Carry-On Size Checker
- Measure your bag fully packed. Soft-sided bags expand when full. Measure the outermost points — including wheels, side pockets, handles and any expansion zippers.
- Pick your unit. Toggle between centimetres and inches; the tool converts both ways without losing your numbers.
- Enter length, width, and depth. Order doesn't matter — the checker sorts your bag's three measurements against each airline's three limits so you get a fair comparison either way.
- Add weight (optional). Many Asian, Middle Eastern and European carriers cap carry-on weight at 7–10 kg. If you skip this, weight checks are ignored.
- Filter by region. Flying short-haul in Europe? Just check European and low-cost carriers. Booked with Emirates? Filter to Middle East.
- Read the failure reasons. If a bag fails, the checker tells you exactly which dimension or weight is the problem — so you know what to fix or which airline to avoid.
Frequently Asked Questions
What's the most common carry-on size?
In North America the de facto standard is 22 × 14 × 9 inches (56 × 36 × 23 cm), used by American, Delta, United, JetBlue, Alaska and others. In Europe most flag carriers use 55 × 40 × 23 cm. If you want a bag that flies almost anywhere, stay within roughly 55 × 35 × 20 cm.
Do wheels and handles count toward the size?
Yes. Almost every airline measures the bag with wheels, handles, side pockets and protruding parts included. When a bag is advertised as "22-inch carry-on" but actually measures 23 inches with wheels, that extra inch is what gets it gate-checked.
What about weight limits?
US domestic airlines generally have no enforced carry-on weight limit. European flag carriers usually allow 8–12 kg. Middle Eastern and Asia-Pacific carriers (Emirates, Qatar, Singapore Airlines, Cathay Pacific, Qantas) typically cap at 7 kg, which is significantly tighter — many travellers get caught out here.
Why is my bag flagged as "too big" for Ryanair when other airlines accept it?
Ryanair only includes a 40 × 25 × 20 cm small bag in the base fare — about the size of a backpack. The standard 55 × 40 × 20 cm cabin bag requires Priority Boarding or a paid add-on. The checker shows both options as separate entries.
Can I bring a personal item on top of my carry-on?
Most full-service airlines allow one carry-on plus one small personal item (laptop bag, purse, small backpack) that fits under the seat in front of you — typically around 40 × 30 × 20 cm. This tool checks the main carry-on; personal-item allowances vary too widely to compare reliably.
Are these limits guaranteed accurate?
Airlines update their baggage policies frequently and rules can differ by fare class, route, and aircraft. Always cross-check with your airline before you fly, especially for low-cost carriers where strict gate enforcement is common.
My data is saved — is it private?
Yes. Your dimensions, weight and region filters are stored only in your browser's local storage. Nothing is sent to a server.
