UpperArmLength
How to measure
Application
Used in clothing sleeve design, prosthetic upper arm sizing, and shoulder-to-elbow ergonomic reach assessments.
Posture
Arm hanging relaxed at the side, fully straightened.
Landmark
Measured from the bony tip of the shoulder (acromion) to the point of the elbow (olecranon).
Tool
Rigid ruler or tape measure.
Assistance
A second person should locate both landmarks and hold the tape ends in place.
Common mistake
Bending the elbow shifts the position of the olecranon. Keep the arm straight and relaxed throughout.
