really easy to measure your bust yourself at home with a measuring tape, just be
careful to be accurate with the measurements. Once you know your right size, you

When measuring yourself at home, wear a normal, comfortable bra with no padding
or push up properties. Then, you simply need to take 2 measurements and work out
the size from the chart below, which is in centimetres.

Underband Size
Firstly, you need to measure your underband size. Using a tape measure, wrap it
around the ribcage, and measure just underneath the bust line. Use the chart below
to work out the first part of your bra size:

Measurement (cm) Underband Bra Size

63-67                            30
68-72                            32
73-77                           34
78-82                           36
83-87                           38

Cup Size
The next step is to work out your cup size. To do this, measure your bust at its fullest
part, being sure not to twist the tape measure and double checking it is even across
the front and back. Check the chart below to work out your cup measurement
against your underband size – remember all measurements are in centimetres.

Bra Size Cup AA Cup   A Cup    B Cup     C Cup        D Cup         DD
30                      75-77   77-79    79-81    81-83        83-85       85-87
32                     80-82     82-84      84-86    86-88       88-90       90-92
34                     85-87     87-89      89-91     91-93      93-95        95-97
36                     90-92     92-94      94-96     96-98       98-100    100-102
38                     95-97     97-99      99-101   101-103  103-105  105-107

If your underband measured 67cm, and your bust 78cm, your bra size is 30A.
If your bust measured 92cm, and your underband your underband 75cm, your bra
size is 34C.
For larger sizes it is recommended to get a professional bra fitting to ensure an
accurate sizing.
