UpperLimbLength
How to measure
Application
Used in prosthetics, full sleeve length in clothing design, and ergonomic reach envelope modelling.
Posture
Stand upright, arm hanging relaxed at the side.
Landmark
Measured from the bony tip of the shoulder (acromion) to the tip of the middle finger.
Tool
Tape measure.
Assistance
A second person should locate the acromion and hold the tape end in place while the arm hangs naturally.
Common mistake
Letting the arm swing forward or backward changes the result. Keep it hanging naturally at the side.
