To calculate your bra size, you will need a soft measuring tape,
and for best results, either remove your bra or wear the
bra that fits you best. Measure directly underneath your
breasts on the rib cage (line 1 on image), making sure to keep the tape
level all the way around your torso. Pull the two sides
together until they meet and lie flat against your body,
but be careful not to pull too tightly. The tape should
feel snug, but not constricting. Enter this as your
Band Measurement. Next, measure around the fullest
part of your breasts (line 2 in the image) to
find your Bust Measurement. Do not round any of
these measurements as the calculator accepts
decimals. Please note: Our calculator
only offers a starting point size. There is no
substitute for a professional fitting or for trying on
If you do
not see the calculator above, go
here to check to see if you have the latest version
of Java installed. The calculator uses Java
version 7 update 7.
Our calculator was the first to allow centimeter conversion as well as decimal input.
