Finding the right bra can be hard,
but we’re here to help make it easier.

Women know that one size never fits all. In fact, finding the perfect style, shape, and size for your girls may look like an ever-revolving door of bras until you find the right one.

Bra Size Calculator

If you’ve ever wondered how to measure bra size, then we’ve got you covered. Here are some simple tips, plus a handy DIY bra size calculator.

Also, if you don’t happen to have a measuring tape, don’t worry. We have a few ideas on alternative tools you can use.

Step 1

First off, you need your measurements. If you can’t get your hands on a measuring tape, find a piece of string, a scarf, or even just an article of clothing that is long enough to wrap around your chest.

Bra Size Conversion?

Bra sizes and measurements vary from country to country. For instance, US and UK bra band sizes are equivalent, but cup sizes vary. When you start to get into EU, Australian, French, and Czechian sizes, though, things start to really get confusing.

For example, a size 36DDD in the US is a size 36E in the UK and a size 80E in the EU. Rather than trying to re-take your measurements for each country, it’s best to use a bra size converter to determine which size you should buy depending on which country you’re sourcing your bras from.
