Ancient Vitruvian Man Geometric Body Proportion Survey

45 mins Ages 7-9 Indoor

An engaging, screen-free learning activity that builds real-world creativity and critical thinking for kids aged 7 to 9.

Materials Needed

  • • Flexible metric sewing tape measure (1 unit)
  • • Measurement recording log sheet (1 sheet)
  • • Pencil and calculator (1 set)

Pro Tips

  • → Have your child stand against a wall with arms spread wide to measure their total wingspan from fingertip to fingertip.
  • → Measure their total height from floor to top of head; in most humans, wingspan equals height (a 1:1 ratio).
  • → Test other Vitruvian ratios: foot length is approximately 1/6th of total height; head height is roughly 1/8th of total height.

Safety First

Ensure space is clear when spreading arms and measuring on the floor.

Step-by-Step Instructions

1

Step 1

Stand straight against a wall to measure total standing height in centimeters with a tape measure.

2

Step 2

Extend both arms horizontally and measure total wingspan from middle fingertip to middle fingertip.

3

Step 3

Measure foot length, forearm length, and head height, recording all numbers in a measurement chart.

4

Step 4

Divide height by arm span, and height by foot length, comparing your ratios against Leonardo's classical 1:1 and 1:6 figures.
