Bra Size Calculator — Find Your Fit at Home
We hate the idea of you having to guess your bra size! Every bra fits a little differently, and if you haven’t had a fitting in a while — or if your body has changed with time, weight, or shape — it’s always best to visit us in-store. Our expert team will give you all the support you need to feel fabulous.
But we understand life is busy, and sometimes you just need to go it alone with your trusty tape measure. That’s why we’ve created a simple Bra Size Calculator to help you get started at home.
How It Works
- Measure your band size (around your ribcage, just under your bust).
- Measure your bust size (around the fullest part of your bust).
- Enter both measurements into the calculator below.
- Click submit to get your suggested size.
Note: This is a suggested size only. Every brand and style can fit differently, so be sure to check the fitter feedback for each product and brand-specific size charts for additional information that will help you find your perfect fit.
Measure for Band Size
Wrap a soft tape measure around your ribcage, right under your bust. Keep the tape snug and level with the floor. Breathe naturally and note the number in inches — that’s your band measurement.
Measure for Cup Size
Now measure around the fullest part of your bust. Arms relaxed by your side, keep the tape straight and gently fitted — no pulling tight. Enter the number in inches for your bust measurement.
