Wallace rule of ninesThe rule is used to determine the spread of a burn in percentage, which is important when you regard the treatment:

– The head is equivalent to 9%
– An arm is equivalent to 9%
– The front or the back of the body are each equivalents to 18 %
– A leg is equivalent 18%

The rule is modified for children, as the head and the lower extremities constitute a relatively larger and smaller part of the total surface area of the body. A good rule to remember is, that the child’s palm is equivalent to 1% of the total surface area of the body. When assessing the total percentage of area burned, only second- and third-degree burns are included.
