Bra Size Measurement (to find a Perfect Fitting Bra)

To determine your cup and bra size, you will need a tape measure (preferably a paper one).

First, we'll determine your FRAME Size.  The frame size is the diameter around your chest JUST BELOW your breasts. Using the tape measure, measure around your ribcage directly under your breasts. There should be no breast tissue measured while determining this number.

Enter your Frame Size: inches
 

The next measurement goes around the chest, over and including the fullest part of your bust (usually at the level of the nipples). Technically, you should take this measurement while wearing a comfortable bra, though this is not mandatory. This is the diameter of your chest + breasts.

Enter your Chest + Breast Size: inches
  

Why Calculate Bra Size?

We need to know about bra size measurement because it helps in doing a proper breast massage, especially to enhance shape and size as well as ensure relaxation. We have experienced that many women do not know exact bra cup size. There is traditional method vs. proper system.

If you want to get proper cup size breast massage, you should know what the current size is and how would you like to enhance or shape it. Therefore, the above calculator will help to know proper cup and common size. There are bra cup size charts. But, this calculator is easy to use. Also, this would help you to buy proper bra. Change from traditional method to proper system.

Is it only for woman? No, whoever curious to know can utilize it. What do you know to 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.

Bra Size Calculator

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 cup size.


Manual Bra Size Calculation

In case of error on the above bra calculator, you can do manual calculation. As its mentioned above, you have to measure bust and rib sizes. Remember, you do not need to change bust size to even number, but you have to do for rib size since bra comes in even number. Also, you have to round the numbers.

Once you get measurements, subtract rib measurement from bust size. After that, use the following bra size chart, and find the cup size. Eg: If bust size is 37 and rib size is 34, subtract by doing: 37-34, and you will get the result 3. Therefore, cup size is C, and proper bra size is 34C.
