Brasy was born from one simple frustration: most women are wearing the wrong bra size — and the calculators that are supposed to help are stuck in the 1950s.
We believe every woman deserves bras that feel good, look beautiful, and support her body — without guesswork, shame, or outdated math.
That’s why we built a free, modern, multilingual bra size calculator that respects real bodies, real measurements, and real lingerie shopping in 2025+.
No more mandatory +4 or +5 inches. We offer four respected methods (Standard, Snug, Loose, Pro Fitter) so you get the fit that works for your body and modern stretch fabrics.
US, UK, EU, FR/ES, IT, AU/NZ — all in one click. Shop anywhere in the world without conversion headaches.
From 28AA to 50N — every size is welcome. No “standard” body assumed. Just accurate help for the body you have today.
We don’t just give you one number. You get sister sizes, fit notes, expert tips, and honest explanations so you can shop smarter.
No upsells, no email gates, no premium nonsense. Just good tools because bra fit shouldn’t be behind a paywall.
We listen to fitters, bra communities, and real users. When better methods or new sizing standards emerge — we’ll update.
