Bra size caculators~ Why you shouldn’t bother
Any woman who has ever worn a badly fitted bra has probably tried to find their “correct” bra size online through a calculator. She is probably as frustrated as the woman who tries to find her size online so she can order a bra, hoping it fits because she cannot try it on in stores. Well, bra size calculators just do not work!! They can give you an estimate, but each one will vary depending on the manufacturer. To illustrate the differences, I’ve selected some calculators, put the requested measurements in each, and was given a response.
85b Results- US/UK 30F. Umm…. US and UK sizes are totally different, and this size is much too small.
Linda’s Online Results- 30J. No US or UK size. It is actually US sizing which would be a UK 30GG. What is interesting about this calculator is that many ladies with a larger underbust measurement then I have will find it accurate. But the calculator does not have anything for a smaller ribcage. Anything smaller than a 30″ ribcage is a 30 band. My ribcage is 26″ so it does not make sense that I would wear a bra band the same size as a woman who has a ribcage 4″ larger than mine.
Mr. Bra Results- 32H or larger. WTF does that mean? Really or larger? And a 32 bandsize? This calculator does not even acknowledge that bras are available smaller than a 32 band.
Vassarette Results- “Measurement #1 is too small for the measurement you gave for measurement #2.” So I guess my boobs are an impossible size. And this is a common US brand for low-cost bras available at stores like Walmart.
Curves and Corsets Results- 26H. The closest one yet, but still not right. Notice that they do not add any inches to the underbust measurement.
So as you can see, each of these has a very different result. I used the same measurements in every calculator, 26″ ribcage/underbust, 37″ fullest bust, and in the case of the first one, 30″ over the breast. And this is not even looking at some of the more ludicrous sizing systems such as Victorias Secret. So obviously a bra size calculator is not the way to go to find your bra size. So really what is? You could use these as a starting recommendation, but the difference in sizes is so large, you’d never find a correct fit. So my next blogs will be sizing with other methods commonly used, underbust measurement only to find size, sizing by eye, and sizing by instructing the wearer about their bra and how it could and should fit better. And maybe while we are at it we can throw in some sizing mistakes commonly made by women in the US.
