Is DD cup big or small?
A DD is a cup size smaller than an E (assuming you kept the same band size i.e and 32DD is smaller than a 32E).
What is a 34B bra size equivalent to?
For reference, any cup with a 34 band size is considered a “true cup” size. This means that a 34AA is in fact a AA cup, just as how a 34B is a true B cup. However, a 34B is also equivalent in cup volume to a 30D, 32C, and a 36A. All three aforementioned sizes are a B cup despite what their cup letter indicates.
Is DDD the same as E?
That is where the confusion comes in so let me make it clear. A DD cup = E for full figure bras, DDD = F, but if you are used to buying a standard bra that comes in cup sizes B-DD and no higher, there will be about a half cup size increase between the DD in a standard style and a DD/E in a full figure style.
Is an E cup bigger than a DD?
They go up to larger, and have a wider variety of Band and Cup Sizes. In the US, the DD cup is the same as the E cup with 5 inches difference. Meanwhile, in the UK, the E cup is bigger than the DD cup. The E cup has 6 inches difference while the DD cup has 5 inches difference.
Is E the same as DDD?
It might seem confusing, but yes a DDD is the same as an F—at times they are labeled differently based on the brand. After size D you can either go up to size DD which is the bra size equivalent to size E, size DDD which is equivalent to size F, and size DDDD which is equivalent to size G.
