Truekare Sizing Information

Important note: The actual size of bra cup varies with band size. As an example, the cup in a 34B is smaller than the cup used in a 38B.

How do you measure bra size?

Figure Band Size
Using a measuring tape, measure underneath the bust to determine your band size. If the measurement is an even number, add four inches to calculate the band size. If the measurement is an odd number, add five inches to calculate the band size. That's because bra sizes don't come in odd numbers such as 35, so, for the sake of comfort, go up an inch instead of down an inch. For example, if you measure 29 inches, add five; your band size is 34.
Note: When measuring, try lifting the breast tissue up so the tape measure is snug on the rib cage.  Also, be sure it is not laying across your shoulder blades...  It needs to be around the small of the back, where your band should lay.
If  your 40C is riding up, Truekare would recommend trying a 38D bra...
Be sure and try plenty of styles until you get a good supported fit because all bras fit a a little differently for everyone.

Figure Cup Size
With your bra on, measure around the largest part of your bust line, then subtract the band size from that. For example, if you measure 36 inches and your band size is 34, the difference is two.

Figure It:
Each unit of difference between the band size and bust measurement represents a letter, or cup size. For example, the above difference of two means that cup size is B.

If bust measurement minus the band size is the same, the cup size is AA.
If the difference equals one, then the cup size is A.
If the difference equals two, then the cup size is B.
If the difference equals three, then the cup size is C.
If the difference equals four, then the cup size is D.
If the difference equals five, then the cup size is DD (E).
If the difference equals size, then the cup size is DDD (F).
