Bra Size Chart

I have a bra size calculator you can use to properly size yourself using not more than a measure tape. Once you have the correct measurements, use our US bra size conversion chart to get your breast and band size in inches and centimeters.

In essence, this is a bra size calculator in inches and centimeters:

When you know your bra size, it’s relatively simple to convert that to inches. For example, if you are a 32A, that means your band is 32 inches.

To determine your breast size, you’d add 1 inch to the band, meaning your breasts are 33 inches.

Each letter in a bra size is associated with an “inch” measurement that you can add to the band size to determine your bust size in inches:

• A cup: add 1 inch to band size
• B cup: add 2 inches to band size
