What cup size are you? Bra measurement cheat sheet
May
Because in the land of bras, everything is more confusing than it really needs to be: Your bust size and your cup size aren’t the same. The bust size is the literal number you just read on the tape measure while contorting yourself into the “L” shape. The cup size, however, is the difference between your band size and your bust size.
Here’s a chart of standard size differences and how they equate to cup sizes:
If your bust size is less than 1 inch bigger than your band size, you’re a cup size AA.
1-inch difference = A
2-inch difference = B
3-inch difference = C
4-inch difference = D
5-inch difference = DD
6-inch difference = DDD or F
7-inch difference = DDDD or G
8-inch difference= H
9-inch difference = I
10-inch difference = J
11-inch difference = K
12-inch difference = L
13-inch difference = M
14-inch difference = N
15-inch difference = O
Here’s an example from start to finish:
Let’s say you measure around your torso and get the measurement of 33 inches. Because it’s an odd number, you should round up to 34. When you measure around your full bust, you get 36 inches. That means there’s a 2-inch difference between your full bust size and your band size. The chart above says a 2-inch difference is equivalent to a “B” cup size, so your final bra size is: 34B.
