Height
To measure your height, stand straight against a wall or door frame. Have a friend place something light and flat (a small book works well) on your head, and mark on the wall the underside of the object. Measure from the floor to the mark in cm.
Chest
To measure your chest, stand straight with your arms resting at your sides while breathing normally ( you don't need to take a deep breath ). Have a friend wrap a tape measure (or string that you'll measure afterwards) under your armpits and over your shoulder blades, recording the largest part of your chest, parallel to the ground. You don't need to add extra for bulky clothes - we'll do that from your measurements, so please don't alter your measurement figures.
