34-36. Grip reaches

34-36. Grip reaches

　

Definition:

In each case the measurement is made to the center or a cylindrical rod fully grasped in the palm of the hand. In dimensions 34 and 35 the arm is raised vertically above the head and the measurement is made from the floor or seat surface, respectively. In dimension 36 the arm is raised horizontally forward at shoulder level and the measurement is taken from the back of the shoulder blades. In each case these are ‘easy’ reaches made without excessive stretch.

　

Corrections:

Some surveys measure reach to the tip of the outstretched middle finger or to the tip of the thumb when it forms a ‘pinch’ with the index finger. Approximately,
- fingertip reach = grip reach + 60% hand length
- thumbtip reach = grip reach + 20% hand length
