Then measure the distance A-D in paces or steps and convert to feet, meters, etc.ġ. If no long-distance measuring device is available, calibrate your step (the walking distance between your two feet-walk normal, don't stretch) or pace (walking distance for two steps) over a known distance (say 50 feet). Measure this distance with a measuring tape. The distance from your eye to the base of the tree is equal to the height of the tree. In sighting to the top and bottom of the stick rotate your eye rather than your head.Ĥ. Your line of sight to the tree base should be as close as possible to horizontal. Walk toward or away from the tree until the tip of the stick is visually lined up with the top of the tree and the bottom of the stick is lined up with the bottom of the tree. Grasp the stick by the tips of the thumb and index finger and hold it out in front of you with your arm fully extended. Break off part of the stick or mark it at the correct length if you don't find one that is exactly right.Ģ. Get a stick that is equal in length to the distance from your eye (cheekbone) to your fingers when your arm is fully extended in front of your face. You can measure heights of very tall objects such as trees by projecting a right triangle (one that includes a 90 degree angle) using your arm, a stick, and your line-of sight.ġ.
