Bra Size Calculator

Bra size is determined by a formula involving two measurements:

  1. Band size (i.e. 34, 36, 38)
  2. Cup size (i.e. A, B, C).

To determine your most appropriate bra size, start by wearing your best fitting bra – unpadded, and not a minimizer or sports bra (underwire doesn’t matter).

If your breasts are sagging in this bra, tighten the bra straps until the crest of your breasts is approximately half way between your shoulder and your elbow – this is the proper location for most breasts. If possible, have someone other than yourself take your measurements. Not only is it faster, it also tends to be more accurate.

Measuring Your Band Size

  1. Holding the measuring tape gently but tightly, measure around your bra directly beneath your breasts after blowing all the air from your lungs – it is best if this measurement is as small as possible. Look in a mirror to make sure the measuring tape is parallel to the floor. The position of your tape measure is critical here.

    If the tape measure is too high, your measurement will be larger than it should be; if the tape measure is too low the measurement will be too small.

  2. When you obtain these measurements, round to the closest whole inch, either up or down. For example, if your measurement is 29 3/8″, round to 29″. If your measurement is 29 1/2″ or more, round to 30″.
  3. Bras come in even band sizes. If the rounded measurement you come up with is an even number, add 4 inches. If the rounded measurement you come up with is an odd number, add 5 inches.
  4. The result is your band size. Example: 33″ + 5″ = 38″ band size

Option 2:
Another method to determine your band size is to measure around your body, straight across your back and chest directly above the breasts directly under your arms. Again, blow all the air from your lungs, stand up straight keeping your arms at your sides. High-busted women and women with implants will have trouble keeping the tape measure parallel to the floor; do your best. If this measurement is an odd number, add one inch and the result will be your band size.

Measuring Your Cup Size

  1. Standing straight, with your arms at your side, measure around your body at the fullest part of your bust while keeping the tape measure parallel with the floor. Do not wear a bra that is padded or is a minimizer. And, make sure the apex of your breasts are half-way between your shoulder and your elbow.

    Note to women with D cup sizes or larger: If your best fitting bra is too tight around your bust, you can also take this measurement without a bra, but hold your breasts up with your hands to where you feel they should be. Have someone else then measure around your fullest part.

  2. Wrap the tape measure around you so that it is just touching, but not binding. If one of your breasts is significantly larger, put some type of padding in the cup of the smaller breast to make it even with the larger breast before taking your measurement.
  3. Round up or down to the nearest inch as you did to find your band size.
  4. Now, subtract your band size measurement from this second measurement. The difference is your cup size.?

Example: 38″ – 34″ (band size) = 4″ = D cup size. The chart below shows you how to determine cup size.

 

Difference Standard Cup Size
0″-1/2″ (1.3 cm) AA
1/2″- 1″ (2.6 cm) A
2″ (5.1 cm) B
3″ (7.6 cm) C
4″ (10.2 cm) D
5″ (12.7 cm)  DD or E
6″ (15.2 cm) DDD or F
7″ (17.8 cm) G
8″ (20.3 cm) H
9″ (22.9 cm) I
10″ (25.4 cm) J

I do not create a lot of remarks, however i did some searching and wound up here Bra Size Calculator.
And I actually do have 2 questions for you if you usually do
not mind. Could it be only me or does it seem like some of
these responses appear like written by brain dead individuals?
:-P And, if you are posting on additional sites, I’d like to keep up with anything fresh you have
to post. Would you make a list of all of all your community pages like your Facebook page, twitter feed, or linkedin
profile?
