Nike Hats & Caps Size Chart


Nike Logo

STEP 1: MEASURE YOURSELF

Measure the circumference of your head using a measuring tape.

Wrap it around your head at the point where the hat will sit (about an inch above your eyebrows).

STEP 2: FIND YOUR SIZE

Use the chart below to determine your size. If you're on the borderline between

 two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.
