Shoulder Breadth Biacromial
The breadth of the shoulders measured between the acromion processes.
ShoulderBreadthBiacromial
How to measure
Application
Used in clothing pattern design and medical skeletal assessment as a measure of underlying bone structure, independent of muscle bulk.
Posture
Stand upright, arms hanging relaxed at the sides.
Landmark
Measured between the two acromion points — the bony tips of each shoulder. This is narrower than bideltoid breadth.
Tool
Spreading caliper.
Assistance
A second person should locate both acromion points and position the caliper.
Common mistake
Confuse this with bideltoid breadth. Biacromial is bone width only. Bideltoid includes surrounding muscle and is always wider.
