Finding the right bra size is an often asked question. Welcome to the HerRoom Bra Size Calculator. An easy, quick way to make the calculations necessary to find your true Bra size. First, we need to tell you up front, that any bra sizing system where a tape measure is involved will not be totally accurate. The reason? A lot of factors can affect your measurements – the bra you’re wearing, the firmness of your breasts, the broadness of your back, the narrowness of your shoulders. These factors and more can give you a false bra size once you’ve measured yourself.
For women who wear a bra size 38D and larger, using this measuring system as a bra size calculator is frankly a mistake. Instead you should be bra sizing starting with your base bra size and tweaking this size based on what you don’t like about your current bra size (check out our Poor-fitting Bra Examples.)
