The most intuitive method is just guessing by cup size. It won’t always be the most accurate method, because of course breasts are each made differently. Shape, size, and even two women with the same cup size may have breasts which weigh differently. The measurements below (breast weight by cup size) were calculated using the average underwire size and the cup diameter of the more common US sized bra brands.
- Bra sizes 32A, 30B, 28C = about 0.5 pound per breast
- Bra sizes 34A, 32B, 30C, 28D = about 0.6 pound per breast
- Bra sizes 36A, 34B, 32C, 30D, 28E = about 0.7 pound per breast
- Bra sizes 38A, 36B, 34C, 32D, 30E, 28F = about 0.9 pound per breast
- Bra sizes 40A, 38B, 36C, 34D, 32E, 30F, 28G = about 1.2 pounds per breast
- Bra sizes 42A, 40B, 38C, 36D, 34E, 32F, 30G, 28H = about 1.5 pounds per breast
- Bra sizes 44A, 42B, 40C, 38D, 36E, 34F, 32G, 30H, 28I = about 1.7 pounds per breast
- Bra sizes 44B, 42C, 40D, 38E, 36F, 34G, 32H, 30I, 28J = about 2 pounds per breast
