Nike Size Chart & Fit Guide

True to size

True to Size

Nike uses standard US sizing across most lines. Dri-FIT tops run slightly fitted — if you prefer a relaxed fit, consider sizing up. Their numeric bottoms (joggers, shorts) correspond to waist measurements and are consistent across collections.

Nike Sizing FAQ

Does Nike run true to size?▾
Yes, Nike generally runs true to size for both men and women. Dri-FIT performance tops are slightly more fitted than standard cotton tees, so size up if you want a relaxed fit.
Should I size up in Nike?▾
Only if you prefer a looser fit or are between sizes. Nike compression gear and Dri-FIT run slightly fitted. Standard lifestyle pieces (Air Force 1 tees, club shorts) are true to size.
How do Nike women's sizes compare to men's?▾
Nike women's sizing is independent from men's. Women's uses XS-XL with bust and waist as key measurements. There's no simple conversion — use Nike's women's size chart directly.
What size Nike joggers should I get?▾
Nike joggers use S/M/L/XL sizing based on waist and hip. If you know your waist measurement, match it to the size chart. For a roomier fit, size up one.
