How to Measure Your Chest & Arm Length

Wear just an undergarment or nothing at all.

Stand up straight with your arms hanging by your sides and breath normally.

Run a soft tape measure under your arm pits over the largest part of your chest and across your shoulder blades.

The tape measure should be snug, but not tight.

Ask a friend to run a soft tape measure from the centre of the back of your neck, across to the tip of one shoulder, then down the outside of your arm to your wrist bone.
