How do you use it? You should know bust and rib measurements in inches. When you measure, wear a normal bra (not pushup) and get natural sizes. See the below image and find where to measure bust and rib.


When you measure, you should do three things. First is round the number to nearest number. If it 36.5 inch, round it to 37. Second is making it even number. If it 37 inch, make to nearest even number 38. Third is do loose measurement, not tight. Note: Properly measured bust size will give exact bra size.

Manual Bra Size Calculation

In case you are purchasing from a lingerie store, you can do manual calculation, as mentioned here, first you have to measure the bust and rib size (in inches). Remember, you do need to change the bust size to the nearest whole number, ex. if bust size is 36.6, then you should take bust size as 37, also you need to measure your rib size and convert it to the nearest whole and even number ex. if your measured rib size is 33.3, you have to convert it to whole and enen number i.e. either 32 or 34, now you have to consider which number is nearest to 33.3, it's 34 right? so your measured rib size should be 34, you have to do so for rib size since bra size derives from rib size and all bra sizes comes in even number.

Once you get the measurements, subtract rib size from bust size. After that, use the following bra size chart, and find the cup size, and ultimately the right bra size. Eg: If bust size is 37 and rib size is 34, subtract rib size from bust size, i.e. (bust size - rib size) like 37-34 in our example, and you will get the result 3. Therefore, cup size is C, and your proper bra size is 34C.
