What bra cup sizes are the same?

Last Updated on March 23, 2022 by Sarah Keene

Bra sizes that share a row are called sister sizes, meaning they share the same cup volume (though they have different cup letters). For example, the row with bra sizes 36C, 38B, and 40A all have the same cup volume, but have different band sizes.

Furthermore, are all C cups the same size? The answer is yes. As the Bra band size (the numbers) increases so does the cup as it naturally gets wider to sit properly on the band.

Also the question is, is a DDD the same as an F? 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.

Similarly, is B cup bigger than C? 2-inch difference = B. 3-inch difference = C.

Additionally, will a 36 C fit a 34 C? For example, if you’re wearing a 34C and the cups fit, but the band is small, you might think “I’ll just go up a band size and try a 36C.” However, sizing up that way will likely result in cups that are too big because a 36C’s sister size is a 34D.SISTER SIZE UP: One actual size larger than your current Band size AND one letter name smaller than your current Cup. For example, if you wear a 34C, your Sister Size UP would be 36B.
