NURSING BRA SIZE

To find your proper nursing bra size, take three measurements. This will give you the most accurate fit. You should buy a nursing bra if you are pregnant and still wearing an under wire or any time your current bra is too small. The best time to buy a nursing bra to fit after the baby is born is within the last 3-4 weeks of pregnancy. If you do not have a tape measure, you can use this printable tape measure.

Step 1. First, measure around your body under your armpits (A). Make sure you put your elbows at your side and relax your shoulders. Round up to the next even number. This is your band size; ie. 36, 38, etc. (A= Band Size on chart below)

Step 2. Measure the fullness of your bust (B). Make sure sure you are not wearing a padded bra. If you are sagging, adjust the straps before you measure to get the most accurate results.

Step 3. Finally, measure around your rib cage just under your bust (C). Now subtract the rib measurement (C) from the fullness of the bust (B). The difference is your cup size. Fullest Part of the Bust(B) - Rib Size(C) = Cup Size as determined by the chart below. Call us at 800-216-8151 with any questions!

Nursing Bra Size Equivalents:

You've taken your measurements, but the size just doesn't seem to add up? Some women carry more of their size in their back or other areas which may make your cup size somewhat skewed. For your convenience, we have given you some examples to help you determine other sizes that may fit you better in the band, but which are the equivalent cup size.

38C 36D 40B
40DD(E) 38DDD(F) 42D
42F 40G 44DD(E)

As you can see from the examples above, when you go smaller in the band, you need to go up in the cup size. If you go larger in the band, you need to go down in the cup size. You should only do this if the calculated size does not fit. If you change to a larger band and don't need to, the back will ride up because it is too loose. Do not buy a D just because the manufacturer does not make a larger cup. Look for nursing bra manufacturers that have a wider range of cup sizes as necessary. Nursing bra manufacturers that make an F cup are Bravado and Amamante and Fancee Free and Elila manufacture bras in sizes up to J K and L cup.
