Height: For best results, stand barefoot next to a doorframe, and then measure from head to toe. Even better, get a friend or family member to do it for you.
Neck: Measure around the base of the neck where the collar normally sits, inserting a finger between your neck and the tape to allow ease in fit.
Chest: Place the tape under the arms and measure around the fullest part of the chest and over the shoulder blades at the back.
Waist: Measure around your natural waistline, keeping the tape slightly loose.
Sleeve: Bend your arm slightly. Measure from the middle of the back of your neck, over the top of the shoulder and down your arm to your wrist.
Head: Measure the circumference of your head across the forehead and just below the curve of the skull in the back.
