SIZING A NURSING BRA
- To size your nursing bra, snugly measure high under the arms and above the breasts to determine chest size in inches.

- Round up to the nearest even size bra (your bra size in inches).
- Measure the fullest point of bust.
- The difference between 1 and 3 tells your cup size:
|
0 - 1 1/2" |
A Cup |
|
1 1/2" - 2 1/2" |
B Cup |
|
2 1/2" - 3 1/2" |
C Cup |
|
3 1/2" - 4 1/2" |
D Cup |
|
5" - 6" |
DD/E Cup |
|
6" - 7" |
DDD/F Cup |
|
7" - 8" |
G Cup |
|
8" - 9" |
H Cup |
If your nursing bra is getting too tight for you either in width or in the cup, get one size larger in the cup and one size larger in the width. This will give you room to grow both ways. For example, if you wear a 34B, get a 36C. If you wear a 36D, get a 38DD/E.
