How do I check my height without a ruler?
Use a £5 note, which is exactly 13.5 cm (5 1/2 inches) long, as a makeshift ruler. (tiberian7/iStock/Getty Images)

Rulers aren't the only ways to measure height. Really, a ruler is just an object that has a known definite length, so a ruler can be any object with a known length. You can find out your height without a ruler by substituting a variety of objects. Take an object you or someone around you is bound to have to use as a makeshift ruler.

Things you need

  • £5 note
  • Pencil

  1. 1

    Take off your shoes and stand up straight with your back pressing up against a wall or other tall, flat surface.

  2. 2

    Mark your height by holding the pencil to the top of your head and lightly drawing a line.

  3. 3

    Take a £5 note and measure from the floor how many lengths there are up to the mark of your height. Every £5 note length is 13.5 cm (5 1/2 inches).

  4. 4

    Fold the note over to make divisions of measurement. Folding it once lengthwise makes a 6.75 cm (2 3/4 inches) measure.

  5. 5

    Use this system to accurately gauge your height if you don't have a ruler or tape measure to hand.
