Why should I know my own bust measurement?

Knowing your bust size will help you determine your cup size. Together with your band size, this will tell you what your bra size is.

Your bra size consists of two measurements
  • knowing your own bust size will give you a better insight into the bra size or sizes that are best for you
  • only a slight change in measurement can change the outcome of your bra size
  • it’s good to realize bra sizes can be very close together
  • it can well be that you would fit more than one bra size

How to measure my bust bra size?

Your bust size should be measured around the fullest part of your breasts.

Don’t pull the measuring tape too tight. You can wear a non-padded bra when you measure. My advice is to measure a couple of times and write down the outcomes.

When you feel you have the outcome correct you then go check my calculator to find your bra size.

The other measurement you would have to know is your band size.

These two measurements will decide which bra size is best for you.


Can I measure my bra size at home?

I’m a strong believer in taking bra measurements yourself. I

f you’re happy with your bra that’s great. You won’t need to do this.

But if you’re not that happy with the way your bra feels and looks, it sure is time to take action.

Advantages of measuring yourself

If you prefer a bra fitting in a lingerie store that’s absolutely fine. But measuring yourself at home, with the help of a friend if you like, has some advantages:

  • you can start measuring anytime
  • there’s no need to wait until your trip to the store
  • the size of a woman’s body and breasts can change easily, maybe that’s why your bra is hurting you
  • by looking up your best bra size you will discover what other bra sizes might fit you too
  • we all have bra sister sizes, meaning bras in different numbers fit the same women
  • depending on the model and brand you’ll know which sizes you can try
  • using my calculator you’ll see what a slight change in measurement will do. Experiment with this.

I own differently-sized bras and they all fit me just fine.

Depending on the brand and model of a bra I may sometimes go for another bra size. If a brand runs a bit small I might take a larger band. To keep the same cup volume I usually go down a cup size to keep the same cup volume.
