In a 2022 study, 87% of participating women said they had at least one breast-related issue when getting active. Over 40% of those women were particularly inconvenienced by excessive breast movement due to a lack of proper support.
Wearing a sports bra is essential for women to have the best possible experiences and outcomes while doing their favorite activity. However, many women struggle to find the proper size and style for their breasts.
Learn about sports bra sizing and styles to find your perfect sports bra!
Sports bras typically have more generic sizing than regular bras. When shopping for a sports bra, you’ll typically only find alpha sizes such as XS-XL.
The exact size of the sports bra may differ from one brand or manufacturer to another. You can check the packaging, clothing tag, or manufacturer’s website and bra size chart to determine the exact size.
At ThirdLove, we provide optimal support by offering sports bras in regular cup-band bra sizes. If you struggle with finding a sports bra that fits you well and that provides enough support for your workouts, try exploring our collection of sports bras to find the perfect one.
Wearing the correct sports bra size is crucial in keeping your breasts supported and comfortable during exercise. A well-fitting sports bra will feel comfortable and supportive while allowing flexibility of movement.
To determine your ideal sports bra size, you will need to become familiar with the different types of sports bras and learn how to measure your sports bra size.
There are several different types of sports bra straps and styles, each one best suited for different breast shapes and activities.
Each brand’s sports bra sizing is different, so make sure to check your measurements against their size chart before making a purchase. Sizing charts typically require you to know your cup size and your band size.
To measure your band size, use a soft tape measure to calculate the circumference of your ribcage just beneath your bust.
To measure your bust size, use a soft tape measure to calculate the size of your bust at its widest point. For most people, the fullest point of the breast will be near the nipple. Your cup size will be based on the difference in inches between your band size and your cup size.
No two sports bras are alike, and different styles tend to be better suited for different types of sports. In the athletic world, there are three categories of sports: low impact, medium impact, and high impact.
Low-impact sports are those that require minimal movement or energy to engage in. A lightweight sports bra will likely be enough to support you through these gentler movements. A few examples of low impact activities include:
Medium impact activities require a moderate amount of movement and energy. As such, it’s crucial to wear a more supportive sports bra when engaging in them. Common examples of medium impact sports include the following:
High impact sports require a lot of movement and energy, which means you’ll need to wear a comfortable and highly supportive sports bra. Examples of high impact activities include:
