How to Measure Your Bra Size Correctly

Finding your true bra size shouldn’t feel complicated. Many traditional fitting methods add extra inches to the underbust measurement, often resulting in bands that are too loose and cups that don’t offer proper support. Learning how to measure yourself correctly at home can help you find a bra that feels comfortable, supportive, and beautifully fitted.

Step 1: Measure Your Underbust

Using a soft measuring tape, measure snugly around your ribcage directly beneath the bust. This measurement determines your band size. The tape should sit firm against the body without feeling tight or restrictive.
If your measurement lands between numbers, round up to the nearest whole number for the most comfortable fit.  

Step 2: Measure Your Bust

Measure around the fullest part of your bust while wearing a lightly cami or no bra at all. Keep the tape level around your body. This measurement should be snug but not restrictive.If your measurement lands between numbers, round up to the nearest whole number for the most comfortable fit. Example 97.6CM round up to 98CM. This works with inches as well 

Step 3: Calculate Your Size

Once you have both measurements, you can use our sizing chart to determine your bra size.

Start by locating your underbust measurement on the chart. This measurement will fall within a small range that corresponds to your band size.

Next, find your bust measurement on the chart. Where your bust measurement aligns with your band size will indicate your cup size.

Our sizing chart is designed to make this process simple and easy to navigate just follow the row for your band size and the column for your bust measurement to find the size that best matches your body.

Example:
If your underbust measurement falls within the 73–77 cm range, your band size would be 34. If your bust measurement aligns with the C cup column, your bra size would be 34C.
