How To Measure A Tree

You will need:

  • A tree
  • A ruler
  • A long tape measure
  • At least two people


1. Stand near the tree, facing its trunk.  Hold the bottom of the ruler in your right hand so it points straight up.  Stretch your arm out and close your left eye.

2. Line up the ruler so the edge looks like it’s next to the tree.

3. Walk carefully backwards until the ruler seems to be the same size as the tree

4. Have your partner use the tape measure to work out the distance from you to the bottom of the tree.  You could put your shoe over one end of the tape to keep it in place.

5. The length of the measuring tape is almost equal to the height of the tree!
