How to measure bra size

You've probably heard that as many as 75% of women wear the wrong bra sizes. Unfortunately, that sad percentage is about right. Finding the right bra size is part science and part art, with a bit of perseverance thrown in.

There's no magic bra size calculator that works on every woman and for every brand, but our recommended bra sizing methods should work for you.

Measuring yourself isn't fun, but it's SO worth it. Wearing the right bra size helps your waist look thinner, your bust look fuller and your body look taller. Your shoulders and back will feel comfortable and your clothes will fit better. Convinced? Let's get to it.

Measure your bra size

Wear your best fitting bra. You may find it helpful to have a second person help you measure. Or you may just want to stand in front of a mirror and measure yourself.

Step 1:

Find your band size

Measure around your chest, just below your underarms, with a tape measure. Measure snugly but not tightly. The number you get is your band size.

Step 2:

Find your bust measurement

Take a loose measurement around the fullest part of your bust.

Step 3:

Find your cup size

Subtract your band measurement from your bust measurement. Then use this simple bra cup size chart to find your cup size.



If your bust measurement is 39 and your band size is 36:
39-36=3, so your cup size is C and your complete bra size is 36C.
