By | November 7, 2013

Welcome to the Push Up Bra Size Calculator. We need to informed you up front, that any bra sizing system used, utilizing a measuring tape will not be totally correct.

A few factors need to be taken into consideration, which will affect your bra sizing measurements:

1). the firmness of your breasts
2). the width of your back
3). the broadness of your shoulders
4). the type of bra you’re wearing when taking the measurement

These are just some of the reasons which can give you a false bra size when you measure yourself.

For a woman who wears a push up bra size 38D and bigger, using the tape measuring system as a bra size calculator is honestly a blunder. Instead you ought to be bra sizing beginning with your current bra size and altering the size primarily based on what you do not like about your existing bra size.

Therefore, here’s the bra size calculation employing a measuring tape. But, bear in mind that it’s not always correct.

3 Easy Steps How to measure and fit a bra

First Step: Measuring the right band size

Hold the tape, measuring parallel to the ground or floor, measure around your bra right beneath your breast. Then expel all the air from your lungs, because you need this measurement to be as little as possible. Roundup all fractional results to the closest whole number, E.g. if the measurement is 32 3/4 then the roundup number would be 33, and if the number is 32 1/4 then the roundup number would be 32.

Second Step: Measuring your cup size

Stand straight, with your hands at your side, measure at the fullest of your breast while wearing your non padded bra. Make certain the tape is parallel with floor and straight.

Roundup all fractional results to the closest whole number, E.g. if the measurement is 32 3/4 then the roundup number would be 33, and if the number is 32 1/4 then the roundup number would be 32.

Third Step: Calculating your bra size:

bra cup size

Minus your band size (See the first step) from your cup measurement (see the second step). Normally, for every difference inches, the cup size goes up by one size.

For example: 
Step 1: 34″ band size = 36″ band size
Step 2: 39″ cup measurement
Step 3: 39″ – 36″ = 3″ or C Cup Size
Your bra Size is most likely a 36C


The cup size measurement starts falling at 4 inches larger than your band size, and if you have droopy or drooping breasts, your size will not be correct.
