Neck – Measure all around the middle of your neck. Keep enough room for you to slide a finger in between the tape and your neck.
Chest – Lift your arms and wrap the tape around your chest. Keep the tape around the highest part of your chest while still under your arms. Drop your arms to get the most precise measurement.
Sleeve – Measure from the middle of your neck, down your shoulder to the elbow. Then take the measurement from your elbow to your wrist. Add the two for your total sleeve measurement.
Waist – Wrap the tape around your waste just above your hip. Keep the tape loose enough to slide a finger between the tape and your waist.
Inseam – Take your favorite fitting pair of pants and place them on a flat surface. Measure along the inside of the leg from the crotch seam down to the bottom of the pants for your inseam. Depending on your sizing preference you can round up or down to get your desired inseam. If you plan on machine washing, take shrinkage into account before you make your sizing decision.
