The Ranga, or Full Pace, was a Númenórean linear measure. The Ranga was said to be a full stride from the rear heel to the front toe, by a full-grown Númenórean man in quick march. It was slightly longer than a yard, measuring 38 inches (3'2", or 96.5 centimetres). 5000 Rangar made up a Lár.
In the later days, when the stature of the Númenóreans decreased, two Rangar was called "man-high" (suggesting that the average Dúnadan was 6'4" or thereabouts). One Ranga was also the average height of a Hobbit (hence the name halfling by the Dúnedain).
