What is the bra size 40DDD? What exactly is the bra size 40DDD? First, it's a combination of a band size and a cup size. The "40" refers to the band and the triple Ds (or "DDD") refers to the cup size.Read more...
The cup size DDD can also be called an F cup size in European brands and an E cup size in UK brands. So, a 40DDD in U.S. sizing would be a 40F in European brands like Chantelle and Prima Donna bras, and a 40E in UK brands like Elomi and Fantasie. Or, put another way the DDD cup size can be the same size as the cup size E and cup size F. This can be very confusing for women when trying to find their 40DDD cup size in European and UK brands. But, problem solved! HerRoom has the solution with our exclusive Universal Cup sizing™ (UCS®). Cup sizes DDD, E and F combined are equal to a UCS® D3 cup size. So, all you need to do is search 40D3 at HerRoom and you'll find all the bras, swimwear, shapewear and more that come in all your sizes.
Every bra size has a set of sister sizes. These are bra sizes where either the band, cup or both are just one size up or down from 40DDD. For examples a 40DDD bra size has sister sizes of 38G (D4) and 42DD. So, these three bra sizes – 38G (D4), 40DDD and 42DD all represent bras with the same cup size (when you go up a band size, you need to go down a cup size to maintain your cup volume) but different band sizes. A 38G (D4) has a smaller band than a 40DDD, and a 42DD has a larger band than a 40DDD bra size. IF a 40DDD and UK 40E and 40F EU bra sizes fit you, this generally means your under bust measurement is 35 to 37 inches, and your over bust measurement is around 46 inches.
Bra size 40DDD is 90F in Europe and Japan, 105F in France, and 18F in Australia.
