Differentiating Between a DDD, E, and F Bra Cup Size (Revelations)

Differentiating Between a DDD, E, and F Bra Cup Size (Revelations)

Bra sizes can be a pain! Above all, finding the perfect fit can be a challenge, too. If you’re having difficulty finding your perfect bra size, consider this article a personal guide, especially if you have a large frame. 

All bra sizes are organized by what they name “cups.” And there are many different types and sizes available in cups. These cups are marked with letters. The higher the letter, the bigger the breast size it is for.

Bra size DDD, E, and F are for extra-large breast sizes. They have a small difference. But it’s a little more complicated, so let’s get right to it!

What is a Bra?

A “bra” is short for the word “brassiere.” It’s a woman’s undergarment for covering and supporting the breasts.

If you’re a woman, you might think its only use is to cover your nipples. However, the whole point of a bra is to redistribute some or all of the weight of your bust onto the shoulders and waist areas. When the bra is fitted correctly, the band and the shoulders hold approximately 80% of the weight.

Several different types of bras serve multiple other purposes. These can be divided into four main categories based on their type. Some bras can be padded, non-padded, wired, or non-wired.

In addition, there are more types depending on the bra’s coverage of your breast. These can be categorized into demi-cups and bras with full range.

Why Do Women Wear a Bra?

Women wear bras for various purposes and benefits. These may include general breast support or enhancing and diminishing the appearance of breast size.

Isn’t it amazing how you can make your breasts appear smaller or larger just by wearing a different type of bra? To do that, you could use a push-up bra for enhancing and a minimizer for downsizing.

Also, breasts consist of fats and glands that suspend over time. Even though they have ligaments for their support, eventually, they will begin to sag.

Therefore, to avoid this, it’s essential to wear a bra. It provides a lift to the breasts and prevents sagging.

Problems With Not Wearing a Bra?

Not wearing a bra can put you at risk of many problems. These may include pain and discomfort being the major ones.

Every woman feels fantastic when she unhooks the bra and throws it across the room after a long day. While it is bliss to go braless, it may surprise you that not wearing one has many disadvantages.

As I’ve mentioned, it would help prevent drooping. Dr. Sherry Ross agrees that if there’s a lack of proper support, the breast tissues will stretch, making the breasts sag- regardless of size.

A bra can also uplift the breasts and reduces the chances of stretch marks by providing additional support to the ligaments trying to keep your breasts high. Therefore, it’s known to offer immense support.

Moreover, this helps prevent neck and back problems, for it could keep your breasts in one place and evenly distributed. They can also help you improve your posture.

However, while a loose bra can lack support, a tight one could cause problems. It’s a given that it might cause you pain, and it can also wear out quickly, which could limit your movement.

How to Wear a Bra?

Are you wearing it the right way? You need to know how to wear your bra for comfort and look.

The correct way to wear a bra is by getting all the hooks clasped. Firstly, lean forward to slip into your bra. Next, adjust the displaced breasts and place them in your bra cup the way you need it.

Then it would help if you ensured that all the hooks are closed and the band on the back isn’t riding up but parallel to the ground. You can make your bra more comfortable by adjusting the slider’s straps. This way, there won’t be any digging marks or leave marks.

Wearing your bra is very important. Even the right size bra can make you uncomfortable and won’t provide adequate support if worn incorrectly.

Which Cup Size is Bigger, A or D?

Cup A is smaller than Cup D. If you’re unaware, there’s a cup size AA- also known as double A, the smallest bra cup size.

After D, you can go up to DD- double D or E equivalent to full-figure bras. Each cup size is 2 or 2.54 centimeters, depending on which brand you shop from. Therefore, an AA is one inch smaller than A, and a DD is one inch bigger than cup size D.

It’s important to note that cup size doesn’t represent volume. Instead, it means how bigger your breasts are than your rib cage.

What’s the Difference Between Bra Cups? (DDD, E, and F)

DDD and E are the exact sizes; the E cup is an inch smaller. You can get your cup size by measuring the difference between your chest and bust line measurements. It means that the cup size indicates well the size of a woman’s breasts about her body size.

All these cup sizes differ in inches. For example, A cup is 1 inch, B cup is 2 inches, and C cup is 3 inches, and it goes on. If you’re still confused, here’s a video to help you:

This video also explains the part you must measure for your cup size.

Difference Between DDD and F Cup (Are They The Same?)

They’re not the same. After DD (Double D) or E, DDD (Triple D) is the next cup size and is equivalent to the size F. Once you hit F or triple D, you continue to go up letters the same way before. 

The thing with DDD and F size is that sometimes they’re the same but only labeled differently depending on the brand. Because they have only a slight difference, it’s okay to wear a DDD one day and try the size DD for the next day. It is because of the difference in brands that make bra cups according to their standard size charts.

When you try other brands and find out that your size has changed, it’s not that you’ve shrunk or gotten more prominent. But it’s just the different sizes that each brand makes.

Is F Cup Bigger Than E Cup?

Yes. An F cup is bigger than an E cup because E is equivalent to DD in some brands, and F is equal to DDD.

While there aren’t any E or F cups in the standard US sizes, a few European brands have E and F cups, and there is some size variation among different brands.

A breast measurement 5 inches bigger than the band size is double D (DD), and 6 inches bigger is the triple D (DDD) size.

Is Bra Size F Bigger than E?


While the bra sizes aren’t the same as how long the straps are, the dimensions of their cups are the same. You can always adjust the band, so you should get a bra that only fits your breasts.

The farther the letter is in the alphabet, the bigger the size. Additionally, the UK system has no DDD cup but only a DD, E, and F cupThe variation is roughly an inch in overbust measurement for each cup change.

Is DDD The Same as E or F?

No. A Bra size DDD is more of an F rather than an E.

Of course, they might be labeled differently based on the brand. If you’re a size E and can’t see any sizes in the store, you can choose size DD instead.

How to Measure Your Bra Size?

It’s quite simple to measure your bra size! 

Firstly, stand upright without wearing a bra and then use a measuring tape to measure around your torso exactly under your bust where a bra band would sit. Make sure it’s an even and steady line. This value would be your bra band size. 

Next, wear your most comfortable bra for the bra cup size and measure around the fullest part of your breasts. 

Then, subtract your band size measurement from the bust size to get your cup size. The difference between the two will be your cup size.

Take a look at this table of different values associated with varying sizes of cups to get a better understanding:

Helpful tip: Always measure in inches!

Which Type of Bra is Best?

The best bra for daily wear is one that is breathable and made out of organic fabric. This fabric may include organic cotton and bamboo, both good choices.

It is suggested to always look out for latex straps or nickel closures, as they could irritate those sensitive to certain materials. When attending special occasions, a push-up bra might be your best friend as it offers a lift that every woman desires. It supports the breasts and makes them look close together.

In addition, a cotton push-up bra is much more comfortable when working. However, it depends on what you find the most suitable.
