Why we built a six-measurement bra size calculator
Many retail calculators fit shoppers into a narrow stock range or use the older add-four method. This project makes the six-measurement method easy to use on mobile and desktop, keeps every value in the browser and explains why the result is only a starting point.
Relationship to r/ABraThatFits and abrathatfits.org

What this bra fit project does not do
The site does not sell bras, rank bodies, diagnose health conditions or guarantee fit. It provides arithmetic, conversions and educational fit checks so users can approach try-on with a more useful first size.
