If you're a runner, swimmer, or another athlete who wears a sports bra, you know that the right fit is essential. The wrong sports bra can make your workout much more uncomfortable and even lead to injury. However, finding the right sports bra for your body type and activity level can be tricky when shopping online—you may have no idea where to start! We'll help you figure out where to start shopping for bras online (and what size) so that you can find one that works for your specific needs.

How to Choose the Right Sports Bra for You

Choosing the right sports bra for you can be a challenge, but it's important to get it right. You want your sports bra to fit properly and support your body while you work out.

  • Choose a sports bra that fits properly. The first step in choosing the right sports bra is finding one that fits well, so make sure to try on several different sizes of each brand before making any decisions. If possible, try on bras at home or at an athletic store where they can help with sizing; this will help ensure that everything fits how it should!
  • Avoid wearing too small or too large of size: It's important not only because they are uncomfortable but also because they don't provide enough support for activities like running or jumping around which will put a strain on them (and possibly cause injury).

If you're not sure about your size, it's generally a good idea to err on the side of caution. Try going one cup size bigger or smaller than what you think might be right—you'll be surprised at how much difference this can make!

Finding Your Sports Bra Size Online

Finding your sports bra size online is easy. First, measure your chest using a tape measure. Then, find the right size by following these steps:

Find a sports bra that fits well and gives you room to breathe. The best way to do this is by going into a store where you can try on different styles of bras in person before making any purchases or making an online purchase. If possible, try out at least three different brands until one works best for your body type and needs (you may have to pay more than $20 per bra).

Once you’ve found a sports bra that fits well and is comfortable, measure the circumference of your chest at the fullest point. The number you get is your band size. Next, measure around your rib cage just below your breasts. This number is your cup size.

You can also use this formula if you don’t have a tape measure: Subtract your band measurement from your cup measurement. For example, if you get 36 inches for your chest circumference and 34 inches for your rib cage circumference, then 2 inches is your difference between the two.

That means that you are a 34B.

How to Put On a Sports Bra and Make Sure It Fits Properly

If you’re wearing a sports bra, it’s important to know how to put on and make sure it fits properly. The first step is determining what size bra you need. There are several different ways this can be measured: by cup volume (the number of cups), band size (the width of the band around your body), or band/cup ratio (how many inches there are between these two numbers). You should also take into account whether or not you have muscle growth or lose weight over time; some brands may run small while others fit larger sizes better than they did when they were new. Once you find a good fit for those factors, try on other styles until finding one that works best with all three measurements—it will likely mean purchasing multiple bras at once instead!

Here are some helpful guidelines for finding and using sports bras online.

When it comes to sports bras, there are a few things you should know before buying one. First, make sure that the bra fits properly and comfortably around your body. Second, decide on what type of activity you will be doing with your new piece of equipment. If this question doesn't answer itself for you already (like most people), consult the chart below:

  • For general fitness purposes, choose an athletic-style sports bra with moderate support at least 18" long (i.e., no underwire). This could include cross-training or general running/walking workouts as well as lifting weights or circuit training workouts like HIITs and tabata intervals.
  • For more intense activities where heavier weight is involved such as powerlifting or Olympic lifting/clean & jerk movements then we suggest choosing a similar style but with stronger support up to 22".
  • Thirdly we recommend choosing multiple sizes so when trying them on in store first then swapping out sizes until finding one that feels comfortable without being too tight when exercising vigorously.

Finally, once purchased, always keep them stored somewhere safe since they're prone to fading over time due to their high-quality fabric.
