How do I calculate my bra size?

 

When it comes to working out what bra size you are, you’ll need to get two bra measurements: your band size and your cup size.

You can work out these measurements by following the steps below:

  1. Remove your bra and stand up straight.
  2. To get your band size, measure around your body - you can ask a friend to help - just under the bust. You should hold the measuring tape quite tightly, but it should still be comfortable and allow you to breathe normally.
  3. Read the number from the tape measure and round up or down to the nearest multiple of two for your UK band size e.g. 34, 36, 38 etc. (the measurement should be in inches).
  4. Next, measure the widest part of your bust, keeping the tape fairly loose to avoid compressing your chest and influencing the measurement. Aim to keep the tape the same height across your bust and back.
  5. Use this measurement to work out your cup size.
  6. Take both bra measurements and add them to our bra size calculator to find your ideal bra size.

Alternatively, you can visit your nearest Triumph store for a professional in-person bra fitting to determine your band and cup size.
