Bra fit measurement how to measure

There are several ways to measure your bra size. And, every body is different. So, one method may work for you while another method may not.

Here we present the three best ways we've found for you to get accurate results. No matter what method you use, take the measurements while wearing a regular everyday bra.

Keep in mind, bra band sizes come in whole even numbers. Bra cup sizes come in letters. And, you may be in between sizes.

Here are some checkpoints for a proper bra fit:

  • Top of the bra cup should completely contain the breast. If bulging exists, the cup is too small. If wrinkling, the cup is too big.
  • Bra brand should fit very snugly around the rib cage.
  • Back of the bra should stay down on the body. If the back rides up the band may be too large.

Traditional Method

Step 1. Band Size
While standing straight and wearing a regular bra, wrap the tape measure around your chest, above the bust. Make sure the tape is straight all the way around you. Pull the tape until it is taut but not restrictive or pinching.

Now, round the measurement to the nearest even number. That's your band size or rib cage measurement.

  • Example
    Band size: 33 ½ = 34 band

Step 2. Cup Size
While still standing and wearing a regular bra, wrap the tape measure around the fullest part of your bust. Again, pull the tape until it is taut but not pinching or digging into your bust.

Make sure the tape is straight and around the fullest part of your bust. If you are in between whole numbers for this measurement, round to the nearest whole number. If you're directly in between two whole numbers, round to the next largest whole number.

  • Example
    38 ½ = 39

Now, subtract your even-numbered band size (step #1) from the whole-numbered measurement in step #2 and convert the difference to your cup size according to the chart below.

  • Example
    Cup Size: 34 - 39 = 5 which results in a DD cup
  • Example
    Final Result: 34 DD

Alternative Method #1

Step 1. Band Size
Measure around your ribcage, right under your chest (where the breastcrease is). Add 5 inches to an odd number and 4 inches to an even number. This is your band size.

  • Example
    Band Size: 33 ½ + 5 = 38 ½ (between a 38 and 40 band size)

Step 2. Cup Size
Now measure one breast from one end to the other (from the front outer edge of one breast to the other's front outer edge (left to right, not around). Do not measure completely around both breasts. This is your cup size.

  • Example
    Cup Size: 9.5" (between a C and a D cup size)

Alternative Method #2

Step 1. Band Size
Measure around your ribcage, right under the bustline. Add 5 inches to an odd number and 4 inches to an even number.

  • Example
    Band Sizes:
    a) Measure is 29"; 29 + 5 = 34; Band = 34
    b) Measure is 34"; 34 + 4 = 38; Band = 38

Step 2. Cup Size
Measure over the fullest part of the bust line.

  • Example
    Cup Sizes:
    a) Measure is 36"; 36-34=2 Cup Size is B
    b) Measure is 41"; 41-38=3 Cup Size is C
