Arm Span

Arm span measurement is a simple measure that is important in the anthropometrical profiling of athletes in many sports in which reach is important, such as rowing and basketball. See also the related arm length measure, which is the length of each individual arm.

purpose: To measure arm length, as long arms may be advantageous for some sports which involve reaching and tackling.
equipment required: ruler or tape measure, wall.
procedure: facing away from the wall, with back and buttocks touching the arms are stretched out horizontally. Measure from one furthermost finger tip to the other.
results: The arm length measures can be compared to the person's height. On average, arm span should be about equal to height. By subtracting a measurement for shoulder width from this measurement you can get a measure of average arm length.

advantages: very low cost, simple and quick test
other comments: It is important for the subject to fully stretch to get the maximum reach, and that the arms are held exactly horizontally. To assist in keeping the outstretched arms horizontal, use a wall that has horizontal lines already on it such as a brick wall. Also measure out from a corner or wall protrusion so that one hand can be stable and all measurements are away from it.

vertical jump test: the initial reach height measure when conducting the vertical jump test is another measure of arm reach.
