My Numbers

Enter your measurements once, and every airline page on this site quietly compares its figures against yours: a planning aid, in your pocket, that never judges.

Your numbers never leave your phone. They are stored only in this browser, on this device. Nothing is transmitted, there are no accounts, and we run no analytics on what you enter. Clearing them takes one tap, any time. One practical consequence: because nothing syncs anywhere, other devices and private-browsing windows won't have your numbers; enter them again wherever you want them.

Compared with each seat's planning width. Sit on a hard chair and measure across the widest point of your hips and thighs.

Compared with seatbelt lengths where airlines publish them (most don't, and we say so when they don't).

Saved for ride-limit comparisons coming in a future update; not used on airline pages.

Same, for published ride weight limits later. Never used to judge anything, here or anywhere.

How the comparisons read

Where you've entered a number, the verdict card on each airline page adds a quiet note: the seat's planning width next to your measurement, one of three plain phrases (Likely fits, Tight, or Plan ahead), and what travelers in that range typically do. The thresholds are simple and worth knowing: Likely fits means your seated measurement is at least half an inch under the planning width; Tight means it's within about an inch and a half over; Plan ahead means more than that. No pass/fail, no colors, no judgment: it's the same arithmetic you'd do yourself, done quietly, with practical next steps attached.

Where the cutoffs come from

Honestly: they are editorial starting points, not science. The half-inch margin under the planning width reflects that a seat you clear with room to spare rarely surprises you; the inch-and-a-half band above it reflects what travelers consistently describe as "snug but workable" territory: soft hips compress, armrests flex slightly, and the planning width is already the narrowest published figure, so surprises tend to be pleasant ones. We expect to refine these numbers over time as better evidence accumulates, and we'll say so when we do. And one number can never capture how differently bodies are shaped and carried. Two people with the same seated measurement can have very different experiences of the same seat. That's why the comparison is guidance, not a verdict, and why the armrest test remains every airline's official yardstick.
