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.
Under-Bust Measurement
Wearing your best fitting bra, wrap a soft tape measure around your ribcage, right under your bust. Keep the tape measure snug and level with the floor. Breathe naturally and relax your shoulders when noting the measurement in centimetres (cm) or inches (in) below.
Full Bust Measurement
Now measure the fullest part of your bust while wearing your bra. This is generally at the line of your nipples if properly supported. Relax your arms and shoulders as much as possible and keep the tape measure level with the floor ensuring that you don’t pull too tight. Note the measurement in centimetres (cm) or inches (in) below.
Your Estimated Size is:
As some bras come in double cup sizes you will need to adjust your estimated cup size depending on the lingerie brand as highlighted in the table below. Please remember that this is an estimate of your size only. We encourage you to refer to fitter feedback on each bra for additional advice or better still, come and visit us for a fitting.
