Athletes have long known the importance of finding a well-fitting sports bra, but even if you’re not a world-class athlete, it’s still important to find a sports bra that fits well and provides adequate support. Unfortunately, many women don’t know how to find a sports bra that fits properly, and as a result, they either wear a bra that’s too loose or one that’s too tight. In this article, we’ll discuss how to find a sports bra that fits well and provide support during any type of physical activity.

Measuring Your Band Size

To measure your band size, wrap a measuring tape around your chest, just under your arms and directly across your back at the widest part. The tape should be level and snug, but not too tight. 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.

Measuring Your Cup Size

To measure your cup size, you will need:
-a measuring tape
-a pencil
-a piece of paper

1. Wrap the measuring tape around your chest, just under your arms. Make sure the tape is level all the way around and is not too tight or too loose. Write down this number.
2. Wrap the measuring tape around your chest again, this time placing it right over the fullest part of your breasts. Again, make sure the tape is level and not too tight or too loose. Write down this number.
3. Subtract the first number from the second number. This is your cup size. If the result is 0, you are an A cup; 1 inch is a B cup; 2 inches is a C cup; 3 inches is a D cup; and 4 inches is an E or F cup.

Trying On Sports Bras

When trying on a sports bra, there are a few things you should keep in mind. First, make sure you wear the right size top. You don’t want your breasts to spill out of the bra or for the straps to dig into your skin. The band should also be tight enough that it doesn’t ride up when you move around.

Once you have the right size top, put it on and adjust the straps so they’re not too loose or too tight. You should be able to fit two fingers under the straps and the band should be level with the front of your chest. If the band is higher than that, it’s too tight; if it’s lower, it’s too loose.

Now that you have the right fit, it’s time to test it out. Do a few jumping jacks or run in place — anything that will get your heart rate up. Make sure the bra stays in place and your breasts don’t bounce too much. If they do, try a different size or style of sports bra.


After reading this article, you should now have a better understanding of how to choose the right sports bra size. There are a few things to keep in mind, such as your body type, the type of activity you’ll be doing, and the fit of the bra. Following these tips should help you find a sports bra that not only looks great, but also provides the support and comfort you need.
