Make a clearly visible mark on the tree trunk at a fixed, measured height above ground level—say, four feet, or six feet. Hold a ruler in front of you and step backwards until the one inch measure on the ruler matches the distance from the ground to the mark on the trunk. Notice how many inches on the ruler match the entire height of the tree. The height of the tree is then the number of inches multiplied by the height in feet of the mark.
