    Ask your child to stand against the panelling of a doorway. Make sure the child is standing straight with heels against the doorway panelling. The child's chin should be pointed straight ahead. If your child cannot stand upright, then a partner can hold the child upright against the panelling by holding the child under the arms.

  2. 2

    Make a pencil mark on the panelling at the spot where the top of his or head rests against the doorway.

  3. 3

    Make a new mark every month -- especially during ages when a child is growing quickly.

  4. 4

    Use a yardstick to measure from the bottom of the floor all the way up to the pencil mark to determine the height of your child.
