No measuring tape? Use a piece of string and hold it alongside a ruler.

1. Chest

Measure around the widest part of your chest just below your armpits. The tape measure should be snug around your chest and shoulder blades.

2. Waist

Measure around your body at the point where your waistband typically rests.

3. Inseam

Measure from just below your crotch to the floor while wearing shoes you plan to pair with the pants. Alternatively, take a pair of pants that fit well and measure from the crotch to the bottom of the hem.

4. Sleeve Length

Measure from the center of the back of your neck to your elbow and continue down to your wrist.
