Common questions
About the advanced calculator
Why use six measurements?
Three underbust measurements and three bust measurements provide more context about tape tension and posture. The result is a starting point; comfort and the fit of the actual bra still matter.
What will my results include?
You’ll get a starting size in your chosen sizing system, sister sizes, and fit guidance to help you decide what to try.
Is this the official ABraThatFits calculator?
No. This is an independent six-measurement calculator. It is not affiliated with or endorsed by ABraThatFits.
