How much body surface area does each leg (front and back) represent in a child according to the Rule of 9's?

5%

7%

In children, the Rule of Nines splits the body so that each leg contributes 14% of the total body surface area, with the front of the leg accounting for 7% and the back for 7%. So when asked how much surface area each leg’s front or back represents, the correct figure is 7%. The full leg (front plus back) would be 14%.
