When you think of big breast sizes, the DD cup is one of the sizes that comes to mind. Less than 1% of women worldwide are a D cup or larger, though the DD cup size is the most common cup size in America. In our article below, we take a look at how big the DD bra size really is.

How Big Is DD?

A DD cup has a 5 inch difference between the bust and band measurements, which makes a DD an inch bigger than a D cup. If you have a DD cup bra size, your breasts can weigh up to 2.15 pounds (975g) each.

A DD cup is also the same as an E cup, depending on what bra brand you buy.

When to Wear a DD Cup

If you notice any breast tissue spillage or experience discomfort while wearing a D cup bra, you may need to size up to a DD cup. When bra shopping, always focus on the fit instead of the size on the tag.

Bra sizing is more of a guide than a set rule. You may find your perfect fit in a bra size you would never have tried. It all depends on the style of the bra.

If you have larger breasts, like a DD cup, you need everyday support. Our favorite? The Elomi Banded Underwire Stretch Lace Bra. It has really supportive bands and a nice, three section cup.

Are There Bigger Cup Sizes Than DD?

There are definitely bigger breast sizes beyond the DD cup size available on the market. Some American brands have DDD/F, G, H and so on after the DD cup size.

The larger your cup size gets, the harder it is to find well fitting bras.

What Bras Should You Wear as a DD Cup?

Finding larger bra sizes can be a challenge since bigger breasts require more support than smaller breasts. If you are a DD cup, there are several bra styles that work well for your body including:

  • Full coverage bras: A full coverage bra offers your breasts complete support, plus also covers and contains all of your bust. 
  • Minimizer bras: If you want your chest to appear smaller, choose a minimizer bra. This style of bra compresses your bust and holds everything in place.
  • Strapless bras: This style of bra can be tougher to find for larger breasts, but you need a strapless option for those dresses that don’t have straps.

The Difference Between the D and DD Cup Sizes

There is a minor difference between D and DD cup sizes. DD breasts are one inch larger in the bust measurement than the D breast size.

The construction of both the D and DD bras is a little different. The full bust bra sizing begins at DD. DD breasts require more support, even with the smaller band sizes.

This is why DD bras have certain features like:

  • Wide padded shoulder straps
  • Wide side panels with boning
  • Seamed cups
  • Wide bra bands
