ForearmLength
How to measure
Application
Used in clothing sleeve design, prosthetic forearm sizing, and ergonomic tool handle length.
Posture
Upper arm hanging naturally, elbow bent to 90°, palm facing upward.
Landmark
Measured from the point of the elbow (olecranon) to the wrist crease.
Tool
Rigid ruler or tape measure.
Common mistake
Measuring to the end of the hand rather than the wrist crease inflates the result.
