An ell (from Proto-Germanic *alinō, cognate with Latin ulna) is a unit of measurement, originally a cubit, i.e., approximating the length of a man's arm from the elbow ("elbow" means the bend or bow of the ell or arm) to the tip of the middle finger, or about 18 inches (457 mm); in later usage, any of several longer units.

| 2 ell = 7.5 feet | 5 ell = 18.75 feet |

| 3 ell = 11.25 feet | 6 ell = 22.5 feet |
