Size Chart
How To Measure
1. Measure Chest
Holding a soft measuring tape horizontally, pull it all the way around the body at the fullest part of the chest.
2. No Measuring Tape?
Grab a string (or even a shoelace), a pen, and a ruler. Pull the string around the chest horizontally at the fullest part — similar to using a measuring tape — and use the pen to mark where one end of the string meets the other side. Then, lay the string on a flat surface and use a ruler to determine the chest measurement.
3. To Find the Bra Size…
Use the chest measurement from steps 1 or 2 to find the bra size on the chart at the top of the screen. If the measurement falls between sizes on the chart, opt for the larger size — a slightly larger bra will be more comfortable than a bra that’s too tight.
*Extended size (+) sports bras differ only in circumference, not length or style.
Quick Fit Tips
Tip 01
Start with Straps
She should be able to fit two fingers between the strap and her body. If it’s too loose, try a smaller size. If it’s digging into her shoulders, go up a size.
Tip 02
Check the Band
Make sure it’s not too tight—she should be able to comfortably fit two fingers between the band and her body. Also, have her raise her arms over her head and make sure the chest band doesn’t ride up—it should fit straight across her ribs.
Tip 03
Jump Without Bounce
When she jumps, there should be minimal bounce. She should feel comfy and confident. You can always try a woman’s size for more support.

All About Bras
Feel Comfy, Feel Covered
Let’s be real: it doesn’t exactly feel normal or natural to wear padding. And for growing girls, padding isn’t even necessary. So all Nike girls’ sports bras are made pad-less. Instead, for added support and smooth coverage, we add a layer of fabric to some bra styles.
Our Feature-Packed Fits
Four styles care for different needs. Nike One has a high neckline and extra coverage for a barely-there feel. Nike Swoosh offers compression and no-slip support. Nike Indy Seamless has thin straps and longer lines for modesty and comfort. And Nike Alate blends in under clothing.
Girl’s or Women’s
There’s no set age when girls start wearing women’s bras—it all comes down to comfort and performance. If girls’ bras don’t offer enough support and coverage, it’s probably time to check out a women’s bra.
