Sports Bra Sizing & Measuring Guide
Finding the best sports bra can be challenging. But that Cinderella moment of throwing on a sports bra that feels just right is worth the effort. To ensure you get the fairytale ending you deserve, start by properly sizing your sports bra.
Keep in mind that your bra size will likely change over time. Weight changes, aging, pregnancy, and other life milestones can impact your breast size. But you don’t need a professional bra fitter every year. All you need is a tape measure!
Get Your Measurements
With a few simple measurements, you can find the best fitting sports bra in a few minutes.
Start with a soft tape measure and ideally take these measurements while not wearing a bra. If this is not an option, wear a non-padded, thin bra that does not alter the shape of your breasts in any way.
Make sure you write down each measurement as you go!
STEP 1:
Get your bust size measurement
Measure all the way around the fullest part of your bust.
Make sure the tape measure is level across your back.
STEP 2:
Get your rib cage measurement
Measure around your rib cage, directly beneath your bust.
Again, ensure the tape measure is level across your back.
STEP 3:
Find your cup size
With a little math and our handy chart, you'll be able to get your cup size.
Subtract your rib cage measurement from your bust size measurement. Take this number and refer to the chart below to get your cup size.
For Example:

Rib Cage
Measurement

39" - 32" = 7"

How To Choose The Best Sports Bra
We realize the number of options and sports bra styles can be a bit overwhelming, but we assure you it will be worth your while to do a little homework. Each sports bra is unique with it's own feature set that serves a specific purpose to help you get the most out of your workout.
We'll try to give you a head start with a few recommendations for making the best sports bra purchase based on activity and support level.
Women's sports bras are usually classified under one of three support levels:
High Impact
Medium Impact
Low Impact
The classification is determined based on how much movement can be absorbed or limited during physical activity. Continue reading for more information and our suggestions on what support level you should look to wear for common fitness activities.
High Impact
High impact sports bras typically feature compression and built-in support in both the straps and bottom band. High-intensity and high-impact exercises like running or kickboxing might require one of these more supportive bras.
Our Pick:
It's high neckline, extra-wide straps and secure bottom band were designed to support your toughest workouts.
Medium Impact
It's the Goldilocks level of support that's not too compressive and not too loose for activities that involve gentle movement like pilates. Also choose a medium impact sports bra for activities like cycling or power walking.
Our Pick:
Kessler Medium Impact Sports Bra
This strappy sports bra is an all time best seller and is one of our go-to medium support options.
Low Impact
A low support sports bra allows for flexibility and longer lasting comfort but doesn't offer much support. A solid option as the top half of yoga clothes and can also be worn when strength training, since your feet are planted.
Our Pick:
You may try not to play favorites but you'll find the soft comfort & great fit from this low impact bra lures you in every time.
Recommended Support Levels by Activity
High or medium impact can work at the gym
For workouts that involve steady movements such as strength training, a medium impact sports bra will work well. But if you're doing HIIT, or any sort of activity characterized by explosive movements, more support is necessary. Depending on your breast size, more intense gym workouts will likely require a workout sports bra offering high support.
Medium impact sports bras are best for cycling
If you're sticking to smooth surfaces on a bike, a medium impact sports bra will limit any bouncing and movement. But if you're planning on taking on dirt trails with a mountain bike, a high support bra may be your best option if you wear a larger bra size.
Go with high impact sports bras for running
When it comes to running clothes for women, a good high impact sports bra is at the top of the list. Jogging is also high impact and will require a running sports bra to match. A high neckline, wide straps and secure bottom band would offer the most support for sprints, jogs, trail runs, and anywhere else your legs can take you.
Wear low impact sports bras for yoga
If you take a gentle yoga class or even hot yoga, the slow movements only necessitate a flexible bra. Pair yoga pants with a sports bra made from stretchy material like PureLuxe or Seamless to help give you a little extra flexibility.
We've got your back...
Now that you know how to choose the best sports bra support level, it's time for the the fun part: shopping! We have a sneaky suspicion we might be able to help you there too as we happen to offer an extensive range of styles in all support levels.
Choose from everyday athleisure styles offering added comfort, to some of that performance-grade material our activewear engineers have been working on in the lab. Perfect for when you need an extra boost crossing the finish line.
You can always count on a pink sports bra to offer a fun, flirty look and red is a popular option if you’re looking to be a little more adventurous.
You might be surprised to learn the most popular option is a simple white sports bra , by quite the landslide too. White is as can’t miss as they come when paired with black leggings for contrast (which just so happen to be the most popular activewear bottoms of all-time).
Comfort and Convenience in the Details
The right ingredients are needed to get optimal support. Instead of oregano or thyme, the perfect recipe for your sports bra includes some of the below features offered by Fabletics.

Sports bras with adjustable straps allow you to fine tune tightness for custom comfort and minimal chafing.
Do you get a workout trying to get your bra off? A zip front sports bra offers an easy way to the bra on and off. Plus, you can unzip partway for more ventilation if needed.
To restrict the movement of your breasts during a workout, a padded sports bra can help. They help keep them pushed closer to your chest and the padding limits bouncing and movement.
Look to front closure sports bras if you want a clean, streamlined look from the back plus easy-on, easy-off convenience.
