Arm span or reach (sometimes referred to as wingspan) is the physical measurement of the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a one-hundred eighty degree angle. The average reach correlates to the person's height. Age and sex have to be taken into account to best predict height from arm span.

Famous quotes containing the words arm and/or span:
“Man is but a reed, the feeblest one in nature; but he is a thinking reed. The entire universe need not arm itself to crush him—a vapor, a drop of water suffices to kill him. But if the universe were to crush him, man would still be nobler than that which killed him, because he knows that he dies and the advantage which the universe has over him; the universe knows nothing of this.”
—Blaise Pascal (1623–1662)
“School-days, I believe, are the unhappiest in the whole span of human existence. They are full of dull, unintelligible tasks, new and unpleasant ordinances, brutal violations of common sense and common decency. It doesn’t take a reasonably bright boy long to discover that most of what is rammed into him is nonsense, and that no one really cares very much whether he learns it or not.”
—H.L. (Henry Lewis)
