Bra Size Guide

Up to 80% of women wear the wrong bra size. Measuring at home takes less than 5 minutes — all you need is a soft tape measure.

Step 1 — Band Size (Underbust)

Wrap the tape firmly around your ribcage, directly under your bust. Snug but not tight.

Step 2 — Bust (Fullest Point)

Measure around the fullest part of your bust, tape parallel to the floor. Don’t pull tightly.

Step 3 — Cup Size

Subtract band measurement from bust measurement. The difference is your cup size.

Example: Underbust 78cm = band 16. Bust 91cm − 78cm = 13cm = F cup. Your size is 16F.

How to Check the Fit

• Band: sits horizontal, two fingers fit under. Provides 80% of support.
• Cups: all tissue inside, no spillage or wrinkling.
• Straps: comfortable, not digging in or slipping.
• Centre gore: lies flat against sternum.
