The modern society generally perceives larger breasts as more attractive. And the DDD cup size (sometimes referred to as F cup size or triple D cup size) is among the largest out there.
In this article, we discuss what a DDD cup size is, what DDD cup boobs (F cup boobs) actually look like, how different they are from other larger breasts, and many other aspects of this cup size.
Important: This article is written for US audiences and US cup size standards. It also applies to the European F cup size.
However, if you’re from the UK or Australia and you were looking for the F cup size, check out our guide to the G cup size (the American G cup size is identical to the British and Australian F cup size).
With that out of the way, let us start.
What Does a DDD Cup Size (F Cup Size) Mean?
Being a DDD cup size (same as F cup size) means that the difference between your bust measurement (measured at the center of your breasts where they’re the largest) and your band measurement (measured right under your boobs) is around 6 inches (15 cm).
This may sound confusing, so let’s clear it up.
As you’re probably familiar, bra sizes in the US are measured with a number and a letter. These are determined by the band and the bust size. To find the right bra size, you need to measure both. Fortunately, this is simpler than it may sound.
The first step is to measure your band size. You can do this by wrapping a tape measure snugly around your ribcage just beneath your bust, making sure the tape measure is parallel to the ground.
The tape measure should be snug, but not so tight that it is uncomfortable. Round the measurement to the largest even number (for example, if you measure at 41 inches, round up to 42). This is your band size.
DO NOT ADD 4-5 INCHES to your measurement, as this is outdated advice. This was a method that was once used, but it’s no longer common. The issue is that it’s still sometimes used to measure the band size. If you stumble on an online resource advising you to add 4-5 inches to your band, just ignore it.
The next step is to measure your bust size. To do this, wrap the tape measure around the fullest part of your bust, making sure the tape measure is parallel to the ground. Make sure the tape measure is not too tight or too loose.
Finally, to calculate your cup size, subtract your band size from your bust size. If the difference equals 1 inch, you’re an A cup, if it’s two inches, you’re a B cup, and so on as shown on the table below. Following the table, if the difference is 6 inches (15 cm), you’re a DDD cup size (F cup size).
For example, if your band measurement is 38 inches and your bust measurement is 44 inches, your bra size is 38DDD (equal to 38F). If your band measurement is 44 inches and your bust measurement is 50 inches, your bra size is 44DDD.
In both of these examples the cup size was DDD. This is because the difference in both is 6 inches.
Note that the “number” part of the bra size is always equal to the band measurement. The only thing you need to calculate is the “letter” part (cup size).
More About the DDD Cup Size
The DDD cup size is very large, which is generally perceived as attractive by a lot of people. They can also give you self-confidence and increased self-esteem.
However, there are some cons to having F cup boobs (DDD cup boobs) as well. Mainly, such large breasts can often cause physical difficulties, such as back pain or neck pain.
Another con is that you don’t have such a large choice of bras. This is because the F cup size is not that common. Lastly, DDD breasts can unfortunately lead to objectification.
What Do DDD Cups Look Like (DDD Cup Breasts Examples)
Up until now we only discussed what DDD boobs are. But, to get a better understanding, in this section we look at examples of celebrities with DDD breasts. Due to the size of these breasts they’re not very common, so there aren’t that many examples.
But, even breasts that are the same cup size can differ widely. That’s because their band sizes can differ a lot. In other words, a woman with a band size of 38 inches and a bust size of 44 inches, and a woman with a band size of 42 inches and a bust size of 48 inches will both be a DDD cup bra size.
However, these two women will look quite different. And even breasts that have the exact same bra size can look different. A slim woman may appear to have larger breasts than she actually does, while an overweight woman may seem to have smaller breasts than she does.
One of the most famous examples of a DDD cup size is Colombian actress Sofia Vergara, who is a 32DDD. This means that her band size is 32 inches, and her bust size is 38 inches.
Another famous example of the DDD cup size is Trinidadian rapper Nicki Minaj, who is a 34DDD. This puts her band measurement at 34 inches, and her bust measurement at 40 inches.

DDD Cup Size (F Cup Size) in Inches
If we measure in inches, a DDD cup size (F cup size) means that your bust size is 6 inches larger than your band size. This means that if your band measurement is 38 inches, your bust measurement is 44 inches. And if your band measurement is 42 inches, your bust measurement is 48 inches.
DDD Cup Size (F Cup Size) in Cm
If we measure in centimeters, a DDD cup size (F cup size) means that your bust measurement is roughly 15 cm larger than your band measurement. This means that if your band measurement is 85 cm, your bust measurement is 100 cm. And if your band size is 95 cm, your bust measurement is 110 cm.

DDD Cup Size and F Cup Size in UK Sizes
The common cup sizes in the US and the UK are identical. But, when it comes to larger cup sizes (from DD boobs and larger), cup sizes start to differ. This is something to keep in mind if you’re an American buying a bra from a UK manufacturer, or vice versa.
As stated already, when the difference between the bust and the band is 6 inches (15 cm), that equals DDD cup size or F cup size by US standards. In the UK, this cup size is considered an E cup only.
UK cup sizing also has an F cup size. However, British F cup size equals the American G cup size. You can check out the following table for more information.
