The distance from the elbow to the fingertip with the arm extended.
ElbowSpan
How to measure
Application
Used in workspace lateral clearance design and ergonomic assessment of the space required at elbow height for working with both arms extended.
Posture
Both arms extended horizontally at shoulder height, fully outstretched.
Landmark
Measured from the point of one elbow to the point of the other.
Tool
Tape measure.
Assistance
A second person is required to hold the tape end and confirm both arms are level.
Common mistake
Bending the elbows reduces the span. Keep both arms fully extended.
