Methods to Measure Your Breast Weight

Method 1Measuring the cup and band size
Method 2Measuring using the displaced method
Method 3Measuring the cup size only

Measuring the Cup and Band Size

The easiest method between the three is by getting the measurement of your bra cup, which is a combination of your band size and cup size.. This method is simple, because you probably already know your cup size, but this measurement is not always accurate, as breasts can be uneven.

Measuring Using the Displaced Liquid

A more accurate way to get your breasts’ weight is through Archimedes’ principle of liquid displacement. This method takes more effort and may feel awkward but gives the most accurate measurement.

Here are the things that you should prepare:

  • kitchen or bathroom scale
  • large bowl
  • towel
  • tray with a sizable lip
  • pen and paper or calculator

Here are the steps that you should do:

  1. Measure the weight of the tray and write the measurement on your paper.
  2. Put the large bowl inside of the tray. Fill the bowl with water up to the brim. 
  3. Place one of your breasts in the bowl until your chest touches the lip of the bowl lightly.
  4. Take out the bowl. Carry the tray with the displaced water and measure it on the scale.
  5. Subtract the weight of the tray from the tray that contains water.
  6. Multiply your answer by 0.9 because your breast tissues are mostly made of fats. Therefore, it has a different density and weight by volume measurement compared to water.
  7. Repeat steps 2 to 6 for the other breast. You have to measure them separately because they may differ in size, shape, and weight.

Measuring the Cup Size Only

The least accurate method of all, you can just go with a generalization based on your cup size.

On average, here is the weight of your breasts based on cup sizes:

When to Seek a Doctor

Seek a doctor’s advice whenever you feel that there is something wrong with your breasts, whether they are too heavy or too light for their size or if there is any pain or tenderness.

If your breasts become too uncomfortable because of their size and weight, talk to your doctor. Your doctor may recommend breast reduction surgery.
