Leonardo Da Vinci‘s famous Vitruvian Man is a drawing of what he believed the perfect human form to be. Along with the famous drawing, Da Vinci gave the following proportions as notes below:

  • the length of the outspread arms is equal to the height of a man
  • from the hairline to the bottom of the chin is one-tenth of the height of a man
  • from below the chin to the top of the head is one-eighth of the height of a man
  • from above the chest to the top of the head is one-sixth of the height of a man
  • from above the chest to the hairline is one-seventh of the height of a man
  • the maximum width of the shoulders is a quarter of the height of a man
  • the distance from the elbow to the tip of the hand is a quarter of the height of a man
  • the distance from the elbow to the armpit is one-eighth of the height of a man
  • the length of the hand is one-tenth of the height of a man
  • the foot is one-seventh of the height of a man
  • from below the foot to below the knee is a quarter of the height of a man
  • the distances from the below the chin to the nose and the eyebrows and the hairline are equal to the ears and to one-third of the face

Get your class practising fractions of an amount by asking them to see if they agree with Leonardo’s claims. Get the tape measures out and get investigating!
