About
Cherry Size finds your true bra size in seconds — and it all happens on your phone. No account, no upload, no tracking.
HOW IT WORKS
Enter two quick tape measurements and get a clear size, your sister sizes, and the equivalent in every system (EU, UK, US, FR, IT and more). Not sure your bra fits right? A quick fit check tells you exactly what to adjust.
THREE WAYS TO MEASURE — no photo needed
• By numbers — the fastest, most reliable way, works offline.
• Shape quiz — four quick questions, the way professional fitters read shape.
• ABTF expert measure — the classic tape method for the most precise result.
YOUR SIZE IN 632 BRANDS
Your size isn't the same at every label. Cherry Size maps your fit across 632 brands and learns each brand's real run as you log the bras you own. Step into the Fitting Room to try a size by cut — push-up, balconette, sports and more each fit a little differently.
MADE FOR REAL LIFE
Track your size over time and add profiles for the people you help. Your recommended size follows your life stage — during pregnancy, nursing or a weight change the app adjusts and gently reminds you to re-measure at the most accurate moment. A first-bra Teen module is available as an add-on.
PRIVATE BY DESIGN
Everything is computed on your device. Your measurements never leave your phone, and we never train on your data. 44 languages, fully on-device.

What's New in Cherry Size
1.7.20
July 23, 2026
What's new: • "Makes my size" — a new filter that shows only the brands that actually carry your size, each with its real size range. • 60-second fit check — after you add a bra, a few quick questions reveal whether the band or cup is off, and which size to try next. • Measuring coach — professional fitter tips while you measure, with a gentle heads-up when a number looks off. • Every result now explains the "why" behind your size, so the cup letter finally makes sense. • A fresher, smoother, more native look — and a calmer, more private feel throughout.
