Bra Size Guide

Now find your cup size by measuring around the fullest part of your bust.

PRO TIP: If there is someone who can help you measure, you’ll probably get slightly more accurate measurements.

Now that we have the measuring part is done! We can determine how to find the perfect fit.

Sizing Charts

The charts below will help you determine your exact bra size. We’ve used the metric system since that’s the most common worldwide, but we know that some countries use different standards, so we’ve also included some conversion charts.

Troubleshooting and Tips 

  • The back of the bra is supposed to be parallel to the ground. If the back is going up, the clasps might be in the wrong location. The middle position is usually the best, and when you can fit two fingers between the fabric and your back, that’s ideal.
  • We’re all shaped differently, so adjust your straps to fit you to maximize comfort and balance. Can you place a finger between your shoulder and the strap after adjusting it? If you can, you have a proper fit. Consider a bra with wider straps if your bust is large.
  • If, after adjusting your bra, it still doesn’t feel right, the model might not be best for your shape and you might want a different model or cut.
  • When the band goes up at the back, lengthen the straps as needed to stop that. If that doesn’t do the trick, select a smaller band size and keep the same cup size.
  • Loose cups, insufficient support, and the top of the cup not touching your skin mean your bra is too large and you need a smaller cup size and probably a smaller band size as well.
  • The underwire needs to perfectly encase your breasts if it is to do its job properly. Feeling squashed is a flashing sign that you need a larger bra.

Don’t settle for discomfort. Be patient and make sure you get the right fit; your comfort and your health are counting on it!
