From Pathfinder Wiki
When the bottom of the paper points to the bottom of the tree, and the fold in the paper points to the treetop, the distance between you and the tree equals the height of the tree. Estimate this distance by pacing it off. Every two steps is roughly 5 feet, or if you prefer metric, every step is roughly 75 cm (which means every fourth step is about 3 meters). For more precision, measure your stride and use that figure.
