This bra size calculator has 3 easy steps and great lingerie tips for
finding the right bra size.
Knowing how to
determine bra size
is quite easy once you understand how the measuring system works. You can do it yourself, or have someone (a friend or a professional fitter) measure you, while you're wearing your most comfortable brassiere...cotton bras work really well for this. You'll need a soft measuring tape, a pen and paper, and the bra size calculator below...
Starting from the back, hold the measuring tape taut and take the measurement around your ribcage, directly under your bust...snugly but not too tight.
Here is an important lingerie tip to get the
correct bra size
- keep the measuring tape straight & parallel to the floor.
Next, round this measurement to the nearest inch. So, for example if you measured 33 1/4", round up to 33"...if you measured 32 1/2", round down to 32". Write this down.
Now, to get your band measurement, take the number you wrote down and add 5" to it if it's and odd number...if it's even number then you add 4". Here's an example...
odd number + 5" = band even number + 4" = band

To determine your cup size, start from the middle of your back, hold the measuring tape and measure lightly all the way around the fullest part of your bust.
Again, keep the tape in a straight line parallel to the floor, so you'll get the correct measurement.
Round this number to the nearest inch. So, for example if you measured 33 1/4", round down to 33"...if you measured anything above 32 1/2", round up to 33". Write this number down.
Now, that you have the band size (1st measurement), subtract it from the (2nd) measurement. Write this number down and scroll down the listed chart below to find your cup size.
Keep in mind that this method of determining
bra sizes
is used only as a guideline. Brassiere styles, sizes and fabrics can vary a lot with different intimate apparel manufacturers. So, for example your favorite
Bali bras
may not have the same bra fit as a
Chantelle bra
in the same size. So, it is important to be flexible with the size tag since it can differ.
