Measuring the height of trees - method 1

Measuring the height of trees - Method 1


  • Choose a tree to measure, and walk away from the tree.
  • Every so often bend forward and look through your legs back to the tree.
  • When you can just see the top of the tree through your legs, stop.
  • Mark this point and measure the distance along the ground from the tree to this point.
  • This is roughly equal to the tree’s height.
  • This works because maths says that if a person can see the top of a tree at a 45-degree angle, then the height of the tree is equivalent to the distance that that the person is from that tree.
