Bra Measurement Guide

Want a simple way to work out your bra size? You’ll need a tape measure in centimetres.

1

Measure Your Band Size

Wrap the tape measure snugly (but not too tightly) around your ribcage, just below your breasts. This measurement in centimeters will determine your band size.

Calculate Your Cup Size

Wrap the tape measure around the fullest part of your bust, without pulling it tight.

Subtract your band size (step 1) from this measurement. The difference in centimeters will determine your cup size.

Combine the Two

Join them together to get your bra size. For example:
Band size
(80cm) = 14
Cup size
(80cm - 75cm = 5cm difference) = B
Bra size = 14B
If you’re between band sizes, size up to stay comfy and supported.
