With that said, let’s learn how to measure for a sports bra.

What to Look for in a Sports Bra

If you are a 34DD, you may be wondering what size sports bra you should get. There are a few things you should look for in a sports bra. First, you want a sports bra that is comfortable. Second, you want a sports bra that will provide support. Third, you want a sports bra that is breathable. fourth, you want a sports bra that is stylish. Keep these things in mind when you are shopping for a sports bra and you will be sure to find the perfect one for you.


Support is the most important thing to consider when purchasing a sports bra. Sports bras are designed to minimize breast movement, not eliminate it altogether. breasts move in an “ figure 8” pattern when we run and jump, so a good sports bra will keep them supported in all directions.

The amount of support you need depends on the intensity of your activity and the size of your breasts. Large-breasted women or those with very active lifestyles may need maximum support, which can be provided by encapsulation or compression bras. Compression bras flatten the breast against the chest and are ideal for small to medium-sized breasts. Encapsulation bras have cups that support each breast individually and are better for larger breasts.

Most sports bras on the market today combine both encapsulation and compression to provide maximum support and comfort. Underwire is not recommended for sports bras as it can cause chafing, but some styles may have a wire encased in fabric for added support.


A good sports bra should be comfortable enough to wear all day, during any activity. It should fit snugly but not too tightly, and it should support your breasts without squishing them. You should also look for a sports bra that wicks away sweat and breathes well, so you don’t end up feeling hot and sticky during your workout.


To find a sports bra that fits, first, look for bras in your regular clothing size. Second, make sure the band around your rib cage feels snug but not too tight—you should be able to slip two fingers underneath. Third, the cups should encapsulate your breasts and compress them (think: shrink wrap) so they don’t move around when you do. Some sports bras have underwire for extra support. And finally, adjustable straps will help you customize the fit.


When you’re looking for a sports bra, style is important, but it’s not the only thing you should consider. An ill-fitting sports bra can cause pain and even lead to injuries, so it’s important to choose one that fits well and provides the support you need. With that said, let’s take a look at some of the different styles of sports bras that are available.

Encapsulation bras
These bras have cups that surround and support each breast individually. They are often more comfortable for larger breasts and offer more support than compression bras.

Compression bras
These bras flatten the chest by pressing the breasts against the chest wall. They are often less expensive than encapsulation bras and can be a good choice for smaller breasts.

Racerback bras
These bras have straps that come together in the back to form a “racerback” shape. They offer good support and are often comfortable for larger breasts.

Pullover bras
These bras don’t have hooks or clasps, so they pull on over your head like a shirt. They are often less expensive than other types of sports bras, but they can be more difficult to put on and take off.


It’s important to choose a sports bra that fits well, so pay attention to sizing when you’re shopping. Sports bras usually come in small, medium, large, and extra-large sizes, but some brands use different size systems. Check the size chart before you buy to make sure you’re getting a bra that will fit properly.


The amount of support you need from your sports bra depends on the size of your breasts and the type of activity you’ll be doing in it. If you have large breasts or you’ll be doing high-impact activities (like running), you’ll need a bra with more support. Compression Bras and Encapsulation Bras are your best bet for high-impact activities because they minimize breast movement and reduce bouncing

How to Measure Yourself for a Sports Bra

Before you can decide on what size sports bra to get, you will need to take some measurements. This will ensure that you get the best possible fit. You will need to measure your chest, under bust, and around your body. With these measurements, you can then consult a size chart to find the perfect size for you.

Band size

To find your band size, measure around your rib cage, just under your bust. The measuring tape should be level and snug. Round to the nearest whole number. If the number is even, add four inches. If it’s odd, add five. This is your band size.
For example: If you measure 32 inches around, your band size is 36. If you measure 33 inches, your band size is 38.

Cup size

To get your cup size, measure around the fullest point of your bust in inches and subtract your band size. So if your fullest measurement is 37 inches and your band size is 34, 37-34 = 3, which would make your cup size a C. You can also use this easy chart to determine your cup size:
