Women with large breasts understand the challenges and hardships that come with a big bust size. Since bigger cup sizes are also not very common, you may be struggling to find the correct information about them.

Usually, it is also a hassle to find a quality bra, in a bigger variety, which fits you seamlessly. 

Therefore, the following article is curated to help you understand one of the biggest cup sizes, H, and find the perfect bra that is supportive, comfortable, and durable.  

What Do H Cup Breasts Look Like?

Breasts with an H cup size are considered above average and amongst the largest cup sizes. The cup size is also not very common, so you may have encountered some issues when shopping for a bra that fits. 

Know how different bra sizes compare to H cups

In addition, a lot of women with an H cup size end up wearing bras with D or DD because they do not realize that size H exists. The reason is that a lot of departmental stores do not stock bra sizes bigger than DD. As a result, around 70% of the women end up wearing an ill-fitting bra their entire life.     

While I have established that H cup breasts are big, how big they look depends on your overall body shape and height. For a woman with a wider frame, H cup size might look proportional to the hips and limbs. The same size would be far more noticeable on a woman with a petite silhouette.

What About Women With Bigger Breasts?

For women with really large breasts, like an H cup, you’ll need an everyday minimizer bra. My vote is the Wacoal Visual Effects Minimizer Bra. I love the seamless underwiring, making this bra actually decently comfortable.

H bra sizes simply follow the same sizing sequence of A, B, C, D, DD and DDD. Note that the DD in the A, B, C, D, DD series is the same as E. To give you some perspective of this cup size, a bust with an H cup will protrude about 8 inches from your body. 

How to Determine Whether You Have H-Size Breasts

A bra that is too tight or too loose can cause discomfort, irritation, and even health issues such as back pain. On the other hand, a well-fitting bra provides support without digging into your skin or causing bulges. 

Even if you are certain that your breasts fall under the H bra sizes, there are still H bra styles you need to know. It’s therefore advisable to use the following tips to determine the exact band size for your H-size cups.  

Prepare to Take the Measurements

Generally, you need a measuring tape to take the measurements, a mirror to ensure you are taking measurements in the right places, and, of course, a pen and paper to write down the measurements. Get a tape that is soft and flexible. This allows it to wrap around your body without digging into your skin.

The tape should have clear markings in inches since the band and cup size are usually in inches. If you don’t have a soft measuring tape, you can use a piece of string and then measure it against a ruler. Ensure that the string is not stretchy. 

Use a mirror to ensure that the measuring tape is positioned correctly and lies flat against your body. If possible, use a full-length mirror so you can see your entire torso while taking measurements. This helps you check the alignment of the tape and ensure it’s parallel to the ground.

Determine the Band Size

Band size is the measurement of the circumference of your ribcage just under your bust. Usually, this is the size represented by a numerical value, such as 32, 34, or 36. 

The band size determines the width of the bra band that wraps around your torso and provides the primary support for your breasts. You can use the following steps to ensure you take the most accurate bra size measurements.

  1. Wear a non-padded bra or no bra at all to minimize the sizing error resulting from the thickness of the bra fabric 
  2. Wrap a soft measuring tape around your ribcage, just under your bust
  3. Make sure the tape is parallel to the ground and snug but not tight, just as you would like the bra cup to be
  4. Take the band measurement in inches and write it down on paper
  5. Round the band measurement to the nearest whole number to determine your band measurement. 

Note that if you are planning to wear a bra with limited elasticity, you need to add four inches to your band measurement if it’s an even number or five inches if it’s an odd number. For instance, if your underbust measurement is 29 inches, adding 5 inches gives you a band measurement of 34. 

On the other hand, if your underbust measurement is 30 inches, adding four inches gives you a band measurement of 34. Adding a few inches also ensures the bra remains fitting even after weight fluctuations, such as weight gain after birth. 

Measure the Cup Size

The cup size is the volume of the space that accommodates the breast tissue. It is represented by letters such as A, B, C, and D in bra sizes. The bust measurements are usually combined with the band size to create the complete bra size, such as 34B or 36H.

As a result, the cup size is the difference between your bust size taken at the fullest part of your breasts and your band size taken just under your bust. The greater the band and bust measurement difference, the larger the cup size. Each inch of difference corresponds to a specific cup size.

Three women wearing bra

For instance, a 1-inch difference is an A cup size, a 2-inch difference is a B cup size, a 3-inch difference is a C cup size, and a 4-inch difference is a D cup bra. You can determine your cup size using the following steps.

  1. Wrap the measuring tape around your chest at the fullest part of your breasts, typically over the nipples. 
  2. Take the bust measurements and round off to the nearest whole number.
  3. Subtract your band size from your bust measurement. 
  4. The result will determine your cup size. For example, if your band size is 32 inches and your bust measurement is 40 inches, the difference is 8 inches, making your bra cup size 32H. On the other hand, a difference of 3 means you have C cup breasts.

Once you know your band size, you will be one step closer to finding a bra that fits you well, without squeezing your boobs or digging into your sides. 

According to research, middle-aged women with bigger cup sizes, such as H, are least likely to be satisfied with their bra size and fit. These women are also more likely to experience upper back pain and dissatisfaction with the size of their boobs.

H Cup Bra Examples

To help you gain a better understanding of how H cup size can look on women with varying band sizes, check out the images below:

The woman in the pic wears a soft, wireless bra that covers her breasts perfectly. Despite the absence of wires, the bra is lined with nylon cups and an inner slang to support the H cup size. Even though there is no hint of cleavage, you can see that the boobs appear big against her slim torso.

Next, I have a girl wearing a 32H mesh bra, with underwires that lift the boobs. Consequently, the boobs appear perkier with a hint of cleavage compared to the previous model.


Woman wearing a deep fuchsia dress

This lady wears the same bra as the one above, only in a bigger band size. Her breasts do not appear too big, in comparison to her underbust size and the previous models. Along with supportive wires, the bra also has wider straps to hold the bra in place.


Woman wearing a printed blue top and black skirt

Finally, the woman wearing a 40H bra seems to have the most proportional breasts, compared to her overall body shape. Her boobs also appear smaller than the other girls featured here, despite having the same cup size.

You will also notice that bras with H cup size also have wider bands to provide maximum support.

Thus, not all women with the same cup size appear to have similar boobs. The general look of the bust size is perceived relative to the body frame. 

Sister Size of H Cup Bra Sizes

Sister sizes in bras refer to sizes with the same cup volume but different band sizes. Adjusting both band and cup size helps find a more comfortable fit. If you go up one band size, you should go down one cup size to maintain the same cup volume. 

For example, from 34B to 36A. If you go down one band sizing, you should go up one cup size to keep the same cup volume. For example, from 38C to 36D. For example, if your usual size is 32C, your sister sizing is 30D (down a band, up a cup) and 34B (up a band, down a cup). 

For a 36D, sister sizing ise 34DD (down a band, up a cup) and 38C (up a band, down a cup). The following table breaks down the sister sizing for the H size. 

Current Bra Size Bra Sister Size Up Bra Sister Size Down

Famous Celebrities With H Cups

Most celebrities, TV personalities, and models have smaller cup sizes, such as B cups, C cups and D cups, which are considered a more attractive breast shape. However, women come in all shapes and sizes, which are unique and beautiful. 

That means you can look great with bigger breasts, while other women might look great in a C cup or D cup. In case you thought all celebrities wear a C cup or D cup bra, check out the gorgeous celebrities rocking the H cups proudly.

Kelly Brook is a model and an actress, appearing in a number of movies and sitcoms. Her curves have always set her apart, as she looks extremely comfortable in her skin.

Top Bras for H Cups

Even though the H bra size is not very common, there are still thousands of women who have the said cup size. It doesn’t necessarily mean you are big bodied. It can be due to hormonal changes or gaining weight. 

For instance, many women might move from DD size to the H size when they are breastfeeding. Once you notice the DD size is becoming tighter, it’s advisable to move to H size to avoid health issues. Unfortunately, the majority of women have trouble finding a H cup bra in large retail stores.

However, there are a few brands that understand that each woman is unique with distinguished bra size. I have compiled a list of bras for bigger busts that will feel like a second skin and support your boobs well enough to relieve some pressure from your back.

Everyday Bra

There are two kinds of bras. One is the fancy kind that you reserve for special occasions or when you want the stylish bra to peek through your clothing. The other is an everyday bra that does the job without being uncomfortable.

Different kinds of bras on a bed

The everyday bra for big breasts has wide straps that are soft and comfortable and a wide, stretchable band that stays in place for a while even when you take off the straps. The cups are large enough to hold your boobs without any spillage and often come with an underwire.

Consequently, an everyday bra designed for women with heavy breasts focuses on fitting seamlessly to the contours of the bust. It does not dig into the sides or the back. Moreover, the fabric used in these bras is usually breathable and soft, so you can wear them for a longer duration without any chafing or redness. 

Racerback Bra

Racerback bras are another great option for big-chested women, especially the ones with an H cup size. They are incredibly supportive, provide you with a perky shape, and keep the straps out of sight. They are often armed with a front closure, which makes putting on and fastening the bras very convenient.

Another huge advantage of the front closure is that the bra cups join against the sternum, so you can enjoy a snug and supportive fit. However, as racerback bras lack the adjustability that comes with multiple back closures, make sure to buy one that fits you perfectly. 

Finally, the closing-fitting property of the racerback bra also allows you to engage in sports and other physical activities without experiencing too much movement around the chest area. Anyone with a massive bust size will appreciate this ability of the bra since it can be quite painful if the boobs bounce too much.

Bandeau Bra

Strapless bras rarely work for women with large cup sizes, since they do not provide ample support, tend to slip down, and are unable to offer an attractive lift. So, if you sport an H cup size and want to don a strapless dress or top, what do you do?

Bandeau bras for large busts can overcome all the challenges and drawbacks of the strapless bra, so you can feel comfortable stepping out in all kinds of strapless, halterneck, or one-shoulder outfits. 

Bandeau bras for bigger chests are available with and without padding. If you are looking for extra coverage, in addition to adequate support, go for the padded variety for a smooth silhouette. 

These bras also have a thicker, more secure band and multiple hooks and eye closures to keep everything in place without constricting your boobs. Finally, quality bandeau bras have a sturdy elastic silicone lining along the cups’ edges to add another layer of security against slipping.

Sports Bra

A sports bra is a bra designed to hold your breasts in place and offer you maximum comfort during physical activities. Although they are not designed for breast size, they are generally supportive bras that can work for these cup sizes. 

Generally, you can find a sports bra for both smaller cup sizes and larger cup sizes. Like other bras, a sports bra can have different bra styles, such a wired bra or a wire-free bra. Some might even offer compression to your larger breasts, and make the breast size appear like D cups or C cups.

Sports bra also comes with additional features such as moisture-wicking design. Since most women with large breasts tend to sweat underneath the breasts, a sports bra might be the right bra for them. In case of weight fluctuations, a sports bra is also elastic, and can remain a perfect fit after weight gain.

Fashion Tips for H Size Breasts

Considering that these breasts are generally larger, they tend to draw people’s attention towards your bust. Usually, this can make you feel uncomfortable, especially when wearing a strapless bra with minimal support. 

The best way to prevent this is to wear an outfit that diverts people’s attention from the bust area or gives you an overall balanced look. Depending on the occasion and weather, the following are some of the best fashion tips for H-size breasts.

  • Go for tops with a V-neckline: V-necklines elongate the neck, complementing the larger cup size. They also draw attention to the center of your chest rather than the size of the boobs.
  • Opt for tops and dresses with structure: Tops and dresses with structure, such as tailored blouses, button-down shirts, or wrap dresses, provide support and can help define your waist. This creates an hourglass silhouette.
  • Consider layering with jackets or cardigans: I find this to be the best solution for these cup sizes. Jackets or cardigans help to add structure and draw attention away from the bust while creating a stylish and polished look.
  • Accessorize strategically: Use accessories like statement necklaces or scarves to draw attention to your face and balance the overall look.
  • Go for outfits with prints and patterns: Patterns that have details and designs away from the bust area can divert attention and create a more balanced appearance. Opt for smaller prints or patterns rather than large, bold prints, as they can be more flattering. Avoid horizontal stripes, as they may give the illusion of added width.
  • Consider lined garments: Bigger busts tend to sweat more. Lined garments can provide additional comfort, particularly if the lining is made from a soft material. This can reduce irritation and enhance the overall feel of the clothing.

Frequently Asked Questions

How Many Inches Is an H Cup?

If you wear a bra with an H cup size, this means that your breasts extend out around eight inches from your chest wall. It is important to note that if you are experiencing sagging, the boobs may appear flatter than eight inches.

How Much Does an H Cup Weigh?

An H cup entails that each breast weighs around 3.35 pounds on average. This is a lot of weight to carry around day in and day out. Thus, wearing a high-quality, supportive bra is crucial to diminish the chances of back pain and fatigue.

How Often Should I Measure for a New Bra Size?

It’s advisable to measure your bra size whenever you notice changes in weight, pregnancy, or if your current bras no longer provide the right support. Factors like age and hormonal changes also impact breast size. 

Changes in physical activity, such as starting a new exercise routine, can also affect your body shape, including your bust. Evaluate your bra sizing if there are significant lifestyle changes.

Final Thoughts

The purpose of the guide is to help you understand the rare H cup size. The remarkable thing about cup sizes is that they look different on women with different types of frame and body mass. 

Consequently, a woman with a 34H bra size appears to have a more curvaceous figure, while 40H bra size provides an almost linear silhouette. 

Finally, since H cup size lies towards the largest end of the bra size spectrum, it requires the maximum amount of support from a bra designed specifically for bigger busts
