Nike Men's Tops

Step 1: Measure Yourself

Stand up straight on a hard surface with your heel against the wall and a piece of blank paper taped to the floor, flush against the wall beneath your foot.

1. Chest
Measure around the fullest part of your chest, keeping the measuring tape horizontal.

2. Waist
Measure around the narrowest part (typically the small of your back and where your body bends side to side), keeping the tape horizontal.

3. Hips
Measure around the fullest part of your hips, keeping the tape horizontal.

Step 2: Find Your Size

Use the chart above 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. If your measurements for chest and waist correspond to two different suggested sizes, order the one indicated by your chest measurement.
