How Much Do Your Breasts Weigh?

Jan 29 2018 0 Comments Tags: bra fit, cup sizes

When the back pain is too much even when not carrying a backpack, the curious turn to the question “how much do my breasts actually weigh?” It might be awkward to just throw them on a scale (and inaccurate besides). Fortunately, there are a few other methods, though they may seem no less awkward.

But backing up first, why does it even matter? Well for some, suddenly gaining breast weight or losing it rapidly might mean a rise or fall in your estrogen and progesterone levels. If you’re pregnant or nursing, that’s to be expected, but it might be telling for your health in other ways. For example, if you’re not menopausal or losing weight but your breasts seem to be shrinking, you might want to be tested for polycystic ovary syndrome (thought to be caused by higher levels of testosterone). If you suspect that you’ve gained or lost breast weight, the actual numbers are good to know.

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 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

The water displacement method is a bit more awkward, but perhaps the most accurate way to weigh your breasts. You’ll need a kitchen scale, a tray with a sizeable lip, a large bowl (big enough to fit at least one of your breasts), and water. Make sure you weigh the empty tray first and set that number aside. You’ll have to subtract it from the total later. You must fill the bowl to the brim with water to get the most accurate measurement. The awkward part is submerging your breast entirely in the water where it will spill out onto the tray. You’ll have to very nearly press your rib cage against the rim of your bowl to get your entire breast. Then just weigh the water and subtract the weight of the tray.

Now since breast tissue has a different density than water, there’s a bit more math involved. Multiply your total ounces by 0.9 to get the correct amount. For example, if the displaced water weighs 28oz, multiply it by 0.9 and the weight of your breast is 25.2oz.

Remember to weigh both breasts, as breasts are rarely exactly the same weight. And that’s okay! However, if the heaviness of your breasts causes unusual pain or concern, whether back pain or abnormal sensitivity, talk with  your doctor to discuss what is healthy. You should also make sure that you’re wearing a cup size that supports you fully. At Hourglass Lingerie, we want hourglass women to be healthy and comfortable, no matter what the size of their breasts. Check out our sizing guide or come by our store for a consultation.
