You can quickly estimate the size of a burn by using the "rule of nines." This method divides the body's surface area into percentages.
See a picture of the "rule of nines" for adults.
See a picture of the "rule of nines" for babies and young children.
The "rule of palm" is another way to estimate the size of a burn. The palm of the person who is burned (not fingers or wrist area) is about 1% of the body. Use the person's palm to measure the body surface area burned.
It can be hard to estimate the size of a burn. If you think a burn is a certain size but you are unsure, it is best to discuss the size of the burn with your doctor.
