Measuring For A Bra

Below is an example of how to measure to get a good fit.  Although some formulas say to add 4″ to the measurement you get underneath your bra band – I think you should start with adding 2″, and then determine how tight or loose you want your bra to be.  Remember, as you go up in band size, the cup will get a bit bigger.  Sometimes to compensate for that, an extender will be the perfect solution.  

 

How to measure and fit a bra:

Step 1, Measure for Band Size:

measuring bra band sizeKeeping 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.

If the measurement is even, add 4″
if the measurement is odd, add 5″

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.

Example:
Step 1: 34″ under measurement +4″ = 38″ band
Step 2: 40″ over measurement
Step 3: 40″ – 38″ = 2″ or Cup “B”
Your size would be 38B

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. 

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
