Chest: Remove any bulky clothing (e.g. jumpers). Place the measuring tape under the arms and measure around the fullest part of the chest. Ensure arms are lowered and hanging loosely by the sides and that the measuring tape is not too tight (to allow for growth).

Height: It may help to do this against a wall or door frame. Stand child up against a wall with shoes off, feet flat and heels together. Shoulders should be relaxed. Looking straight ahead. Measure from the crown of the head down to the base of the feet. Making a small mark on the wall and measuring from the mark to the floor may make this easier.
