ABOUT THIS SITE.

Airline size charts are a mess. Every carrier lists slightly different numbers, half of them ignore wheels and handles, and you only find out your bag doesn't fit when a gate agent is waving a $65 fee in your face. willmybagfuckingfit.com fixes that.

Type in your bag's dimensions and we tell you — instantly, for free — exactly which airlines it flies on as a carry-on or personal item. No guessing, no surprises at the gate.

How we check

We keep an up-to-date list of each airline's published carry-on and personal-item limits — currently 16+ airlines, from the US majors to the budget carriers and the big international names. When you enter your bag's outer dimensions (wheels and handles included — the way an airline sizer measures), we compare every dimension against each airline's limit and give you a straight verdict: fits, borderline, or no.

Every airline entry links to that carrier's official policy so you can double-check the source yourself. Sizes are guidance — airlines change rules and gate agents vary — so when it's close, we tell you it's close.

The bag & gear recommendations

When we recommend a bag, it's because we've measured it against those same airline limits — not because someone paid for placement. The whole point of the site is that the numbers decide.

How we keep the lights on

The tool is free and always will be. Some of our links are affiliate links — if you buy through one, we may earn a small commission at no extra cost to you. It never changes the price you pay or which bags we recommend. Full details are in our privacy policy.
