# Bra Sizes: Difference between Cup E and DD (Double D)

Question by Guest | Last update on 2021-04-06 | Created on 2015-11-03

I am a little confused about the cup sizes of bras. I know, that with increasing size there are the cups AA, A, B, C and D. But what is the next size after cup size D?

Up to now, I have already seen both, bras with an E cup as well as D cups, that is double D.

So, what size is there after D? E or DD? And what is the difference between the two cup sizes? Or does "Double D" just mean "very big", because it is often used in this sense?

In the European bra size system, there are no double letters such as Double D. In this system, after the cups A, B, C and D, there are the cup sizes E, F, G and so on. The term Double D is coming from the British and US-American systems.

In the American system, instead of  A, B, C, D, E and F, there are the sizes A, B, C, D, DD, DDD and DDDD. Thus, the American "Double D" corresponds to a European E cup.

In the British system that is slightly different. There, DD is an individual size between D and E. In the British system, you count  AA, A, B, C, D, DD, E, F, FF, G, GG, H, HH, J and so on. The distance between the individual sizes is an inch for each.
