How To Measure Correct Bra Size ?

How to Measure Yourself

We recommend finding an expert to measure you instead of measuring yourself, but this is a great place to start if you don’t have the time or proximity to the lingerie section of a department store or if you’re wondering how to measure bra size at home. Shopping for bras online can be really tricky, so make sure you understand the return policy before you purchase! To figure out how to measure bra size for plus size women, you’ll need:

  • Soft measuring tape (if you’re wondering how to measure bra size without a measuring tape, you can use string)
  • Mirror or friend
  • Your best-fitting non-padded bra with underwire
  • Basic arithmetic (or a calculator)
Step 1: Determine Your Band Size

Using a soft measuring tape, measure the circumference of your band which is directly under your bust. Essentially, this is the circumference of your rib cage. When measuring, make sure the tape is parallel to the ground so that it is level. Round to the nearest whole number. If that number is odd, round up to the next even number.
Step 2: Measure Your Bust Size

Wearing a non-padded bra like the Elomi Matilda Plunge Bra, measure the circumference of your body around the fullest part of your bust. Using a mirror or a friend, make sure that the tape is level while you are measuring. Your arms should not be included in this measurement. Round to the nearest whole number. Remember your bust measurement, because here is where things can get tricky!

Step 3: Calculate Your Cup Size

Using both your band and bust measurements, you can decipher your cup size. Take your bust measurement and subtract your band measurement to find the difference between the two. Once you determine the difference between bust and band, use the chart below to determine your cup size. For each inch, the cup size goes up by a letter.

Ex: If your band measurement is a 42 and your bust measurement is 45 inches, there’s a difference of 3 inches. That 3-inch difference determines your cup size is a C.
