How To Find The Right Sports Bra Fit

Three Tips For Finding the Right Fit

Because when it fits, it's a beautiful thing.

1. Check the Straps

Two fingers should fit comfortably between the band and your shoulders.

2. Check the Band

Raise your arms, making sure the band stays in place.

3. Test the Support

Move in it. You should feel comfortable and confident.

How To Measure

Nike Sports Bras run from size XS to 3X. To determine what sports bra size you need, we'll walk you through how to take two measurements: band and halter. Don't worry if you don't have a soft tape measure—use a piece of string instead and measure that with a tape measure.

1. Measure Your Band

Measure around your ribs just below your breasts. Keep the tape measure level to the floor and snug to your body, but not too tight.

For the most accurate measurement, relax, breathe out and have at least one arm at your side (ideally both arms are at your sides, but that's tricky unless you have someone measure for you).

2. Measure Your Halter

Start with the measuring tape around the back of your neck and measure the distance from apex to apex. Apex is the fullest, most prominent part of your breast.

For the most accurate measurement, look straight ahead, relax, breathe out and ideally put both arms at your sides.

3. Find Your Size

Use the chart below to determine your sports-bra size based on your band and halter measurements.

If your measurements lead you to a shaded size on the chart, that's our recommendation. If your measurements lead you to a size that's not shaded, start with this size, but you may want to try on additional sizes to make sure the fit is right.
