Everything You Need to Know About Bra Fitting


STEP 1: Measure for band size:


Keeping the measuring tape parallel with the ground, measure around your bra directly under your bust after expelling all air from your lungs - you want this measurement to be as small as possible. Round all fractional measurements to the nearest whole number.

Measure using the instructions above, then find your band size here
If Your Measurement is:

After a 38 band size, the band size should be the closet higher even number to your actual measurement So, 41.5" is a 42 band. A 41" measurement is a 42 band.
 

STEP 2: Measure for cup size:


Standing straight, with your arms at your side, measure at the fullest part of your bust (while wearing a non-padded bra) making sure the measuring tape is parallel with the ground and not binding.
Round all fractional measurements to the nearest whole number.

STEP 3: *Calculate your bra size:


Subtract your band measurement (step 1) from your cup measurement (step 2). Generally, for each inch in difference, the cup goes up by one size. See the cup size conversion chart below.

Example:
Step 1: 34" under measurement = 36" band
Step 2: 38" over measurement
Step 3: 38" - 36" = 2" or Cup "B"
Your size would be 36B

The cup size calculation starts falling apart at 4 inches larger than your band size, and if you have droopy or pendulous breasts, your measurement will not be accurate.

If The Differtence Is: Your Standard Cup Size Is: Your *Universal Cup Size™ Is:
0" to 1/2" (1.3cm) AA
1/2"- 1" (2.6 cm) A
2" (5.1 cm) B

3" (7.6 cm) C
4" (10.2 cm) D D1
5" (12.7 cm) DD * or E * D2
6" (15.2 cm) DDD * or F * D3
7" (17.8 cm) G * D4
8" (20.3 cm) H * D5
9" (22.9 cm) I * D6
10" (25.4 cm) J * D7
 


Universal Cup Sizing™* Cup sizes larger than a D are called different letters by different brands (a DDD cup size in one brand can be called an E or F in other brands). So know your Universal Cup Size and you can find your correct size in any brand at HerRoom. Learn how to find your Universal Cup Size™


*Please Note: This bra measuring method becomes very unreliable at bra sizes 38D and larger.

*Important Note: this measuring system tends to become less accurate as the cup sizes go above a D. Additionally, some manufacturers name larger cup sizes differently. See "The Proper Bra Measuring Techniques for Plus-Size Women".
