How to Measure Your Bra Size Correctly

Finding the right bra size is essential for comfort and support. Follow these two simple steps to use our Bra Size Calculator effectively:

Step 1: Measure Your Band (Underbust)

Wrap the measuring tape snugly around your ribcage, directly under your bust. Make sure the tape is parallel to the ground and expell air from your lungs slightly. Round to the nearest whole number.

Step 2: Measure Your Cup (Bust)

Measure around the fullest part of your bust. Keep the tape straight but loose enough not to compress your breasts. This difference between your band and bust determines your cup size.

International Bra Size Chart Conversion

Sizes vary by country. Our tool automatically converts between US, UK, EU, and French sizing systems. For example, a US 34DDD is equivalent to a UK 34E and an EU 75F. Always check the brand's specific chart as fits may vary.
