How to Measure Your Bra Size at Home

Wearing a well-fitting bra can help prevent sagging and maintain the shape of your breasts. Knowing how to measure your bra size at home can provide more privacy and comfort than having someone else measure you.

How to Measure Your Bra Size at Home

Bras come in different brands, sizes, and styles, with most celebrity bra sizes ranging from 32C, 32D, 32F, 32DD, 34B, 34E, and 36DD. Usually, these sizes help boost confidence when in public while maintaining the shape of the breasts.

The right bra size can help enhance your appearance in clothing. The following steps can help you determine your bra size depending on your bust and band size.

Find Out Your Bra Band Size

Band size is the measurement of the circumference of your torso, just under your breasts. It is advisable to take the measurements while braless.

Using a tape measure, take the measurements of your torso directly where your bra band normally sits. If the measurements have a decimal point, round them off to the nearest whole number.

If you get an odd number after rounding off, add five; if you get an even number, add four. Since your band size is the sum of your calculations, this means if you measured 31 inches, your band size is 36, and if you measured 34 inches, your band size is 38

Determine Your Bust Size

Wearing a bra that fits properly can provide comfort and support, reducing the chances of getting back pains. The bust size simply refers to the measurement of the fullest part of your breasts, typically taken across the nipples.

Again, loosely run your tape measure around the fullest part of your bust or under your shoulder blades. Note the number of inches you are, which is your bust size.

Calculate to Determine the Cup Size

Cup size is the measurement of the volume of your breasts, which you can calculate by subtracting the band size from the measurement of the fullest part of your breasts. You can then use the difference to determine your cup size.

Cup sizes range from A to K, where A is the smallest and K is the largest. Each letter represents an increment of a one-inch difference between the band size and bust measurement. If the difference between your band and bust measurement is 1 inch, you are an A cup.

If your bust size is 36 inches and the band size is 32 inches, the difference is 4 inches, meaning that your bra size is 34D.

How to Know If a Bra Fits Properly

Typically, women have different breast shapes that require different support. Since bras come in different styles and brands, you can know that the bra is fitting if:

  • The band around the body forms a straight line
  • You can place a finger between the should and the strap without straining
  • The cup encloses the entire breast
  • No double breasts are forming between the cups

Must I Use a Tape Measure to Determine Bra Size?

It’s not a must, as you can use a ribbon or a string as long as it is not stretchy. Measure your band size and then transfer the measurements on a ruler. Do the same with your bust size.

How Do I Know If My Bra Cup Size Is Too Big?

You can determine whether your cup size is too big if there is a gap at the top of the cups when standing or leaning over in front of a mirror.

What Causes My Bra Straps to Keep Falling?

Bra straps can keep falling if the elastic has worn out. The straps can also fall if the bra is oversize.
