How to Properly Measure Your Arm Length

Note: For Arm Length and Forearm Length, You will need a short (about a foot long) piece of broom handle. The broom handle should have a slot cut about half its length to accommodate the blade of a tape measure.
  1. Have the subject grip the non-slotted end of the dowel in their hand with the bottom of the slot just above your hand and the slot parallel with your outstretched arm.
  2. Have the subject stand with their arm outstretched to their side.
  3. Lower the arm to about a 45 degree angle and move your hand slightly forward of the body.
  4. Place the case of the tape measure over the fingers with the end of the tape passing through the slot.
  5. Extend the end of the tape till it reaches the small depression in the shoulder joint.
  6. Read the measurement on the side of the dowel closest to the shoulder.
  7. Record this measurement.
