D cup boobs are one of the most desired breast sizes. They’re on the larger side, but they’re not huge. Given this, most women that are wearing a D cup size can consider themselves lucky.
In this article, we’ll discuss what exactly it means to be a D cup size, what D cup boobs actually look like, how different they are from other cup sizes such as the B or C cup size, and everything else that may interest you about the D cup bra size.
Let us begin!
What Does a D Cup Size Mean?
Being a D 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 4 inches (10 cm).
Although this may seem confusing, we’ll explain in detail what it actually means and how to measure your cup size.
The thing that you probably know is that bra sizes have a number and a letter. The “number” measures your band size (measured right below your breasts), while the “letter” stands for the difference between your bust size and the band size.
To get to the correct bra size, you need to get both the “number” and the “letter” part correctly. Fortunately, this is simpler than it sounds.
So, the first thing you need to measure is your band size. With a tape measure, you should measure all the way around your rib cage, right below the breasts. Stand straight when doing so to get the most accurate result.
If you get an odd number (for example, 31), increase it by one (in this example, to 32). This is because bra sizes are represented with even numbers.
DO NOT ADD 4 INCHES to your band measurement. There’s an outdated method that says that once you measure your band you should add 4-5 inches to it. While this was true many years ago, it’s irrelevant now. Yet, I still hear this advice circling around on the internet. If you stumble upon it, ignore it completely.
Once you have the band size, you must get the bust size too. You can find out this number by measuring all the way around your breasts. Instead of measuring under them, you measure right across the center of your breasts, where they’re the largest.
To recap, you need to measure the size of your band, which is your chest size measured right under your breasts (this is your band size or the “number” component in the bra size). Then, you need to measure the size of your bust, which is your size at the point where your breasts are the largest.
Once you have these two measurements, the cup size is easy to find out. You just need to take the difference between your band size and your bust size. If the difference is 1 inch (2.5 cm), you’re an A cup size, if it’s 2 inches (5 cm) you’re a B cup size, and so on as shown in the table below.
Following this, a D cup size is when the difference between the two is 4 inches (10 cm).
Let’s look at an example of this. If your band measurement is 32 inches, and your bust measurement is 36 inches, your bra size is 32D (36 inches minus 32 inches = 4 inches = D cup size). And if your bust measurement was 33 inches instead, you would be 32A (33 inches minus 32 inches = 1 inch = A cup size).
If your band measurement is 36 inches, and your bust measurement is 40 inches, your bra size is 36D.
Note that the “number” part of the bra size is always equal to the band measurement. The only thing we calculate in these examples is the “letter” part (cup size).
Benefits of the D Cup Size
The D cup size is a cup size that’s on the larger side. According to a survey of 2,000 Americans and Europeans, it’s one of the most desired cup sizes with around 15% of women and 20% of men considering the D cup size as ideal.
Although they are the coveted cup size, women with D cup boobs may run into issues such as back pain. This is due to their breasts being much heavier compared to A or B cup boobs.
Apart from being large enough, another benefit of being a D cup size is that most manufacturers produce bras for your size. This isn’t necessarily the case for larger cup sizes, for which it may be more difficult to find a bra that fits.
What Do D Cup Boobs Look Like (D Cup Breasts Examples)
Now that you know how to measure if you’re a D cup size and what are the benefits of this size, let’s look at examples of how D cup boobs actually look like.
Note that many of the celebrities shown here are generally thought of as having perfect breasts. That’s simply because D cup boobs are considered visually very attractive.
Another thing to note is that the appearance of their breasts differs a lot, even though they’re the same cup size. That’s because although they have the same cup size, they may still have completely different band measurements.
Remember that a woman with a band measurement of 32 and a bust measurement of 36, and a woman with a band measurement of 38 and a bust measurement of 42 will both be a D cup size, and yet they’ll look very different.
And even women who have the completely same bra size may be perceived differently. For example, it may seem that slimmer women have larger breasts than they actually do.
A prominent celebrity with a D cup size is American singer Katy Perry, who is reportedly a 32D cup size. This would mean that her band size is 32 inches, while her bust size is 36 inches.
Another celebrity who is a D cup size is American tennis player Serena Williams, who is a 36D bra size. According to her cup size, her band is 36 inches, and her bust is 40 inches.
D Cup vs C Cup
The C cup is one cup size smaller compared to the D cup. This means that for women with the same band measurement, the bust of a woman with C cup boobs will be 1 inch (2.5 cm) smaller compared to a woman with D cup boobs.
These two cup sizes are both some of the most coveted bra sizes. The C cup size is considered as the ideal cup size, while a D cup is an above average cup size in most of the world.
D Cup vs DD Cup
The DD cup (E cup) is one cup size larger compared to the D cup. This means that for women with the same band measurement, the bust of a woman with DD cup (E cup) boobs will be 1 inch (2.5 cm) larger compared to the woman with D cup boobs.
D Cup vs B Cup
The B cup is two cup sizes smaller compared to the D cup. This means that for women with the same band measurement, the bust of a woman with B cup boobs will be 2 inches (5 cm) larger compared to a woman with D cup boobs.
D Cup Size in Inches
Measured in inches, a D cup size means that your bust measurement is 4 inches larger than your band measurement. This means that if your band measurement is 32 inches (or 31 inches, since we round up to the largest even number), your bust measurement is 36 inches. And if your band measurement is 36 inches, your bust measurement is 40 inches.
D Cup Size in Cm
Measured in centimeters, a D cup size means that your bust measurement is a whole 10 cm larger than your band measurement. This means that if your band measurement is 70 cm, your bust measurement is 80 cm. And if your band measurement is 85 cm, your bust measurement is 95 cm.

D Cup Size (UK)
Cup size measurements differ in the UK from those in the US. But, the difference between the US and UK sizes begins at even larger cup sizes than the D cup bra size.
When it comes to D cup size in the UK, it’s pretty much the same as in the US. For example, a D cup in the UK also means that the difference between the bust and the band measurement is 4 inches (10 cm).
So, just like in the US, a 34D in the UK would mean that the person has a band measurement of 34 inches and a bust measurement of 38 inches.

How Big Is a D Cup?
A D cup size is defined by the 4-inch difference between the bust size and the band size. This means that you can’t simply answer how big is a D cup without knowing the band size. Cup size 32D is different from 36D, and even more different than 40D.
Is D the Smallest Cup Size?
D is definitely not the smallest cup size. In fact, it’s a cup size that’s considered large, but not huge. The cup size that’s often regarded as the smallest is the A cup size, although there are even smaller cup sizes (such as the AA cup size).
If you have D cup boobs you can consider yourself lucky, since this is a cup size that many women desire. Here, we discussed what it means to be a D cup size, what D cup boobs really look like, how bigger they are from other cup sizes, and other aspects related to this cup size.
