There are many ways that you can be burned as well as there being more than one way to make an estimation in regard to the percentage of burn injury from thermal or chemical burns. This discussion reviews the depth of burn and the three methods for determining the extent of burn injury using percentages.

The Rule of Nines
The rule of nines is an anatomical and graphical tool that divides the total body surface area (TBSA) into segments that are multiples of 9%.
The percentages used for each body part are different
between adults and children.
This is the easiest method to use for adults and children older than 10yrs.

Lund & Browder Chart
The Lund & Browder chart is considered the most accurate of all the methods as it assigns a specific number to each body part.
This method is most often used to measure burns in infants and young children because it allows for developmental changes in percentages of body surface area.

The palm method is a tool whereby the size of the patients palm is used as an indicator for specific percentage of TBSA.
The surface area of a patients palm equals approximately 1% of TBSA.
This method is particularly useful where the burn has an irregular shape or has a scattered distribution.
