The BSA Comparison formula compares a body surface area to the average of one of the specified demographics and provides a percentage. The formula is:

`BSA % = (BSA)/(muD)`

Demographic Means

The mean values for the demographics (μD) are as follows:

**Mean Body Surface Area (male and female)**
Age Range	Male	Female
Neonate	0.243 m²	0.234 m²
2 years old	0.563 m²	0.54 m²
5 years old	0.787 m²	0.771 m²
10 years old	1.236 m²	1.245 m²
13 years old	1.603 m²	1.55 m²
18 years old	1.98 m²	1.726 m²
20 to 79 years old	2.06 m²	1.83 m²
80 and above	1.92 m²	1.638 m²

The Body Surface Area Averages are:

Female Neonate: 0.234 m²
Male Neonate: 0.243 m²
2 year old Female: 0.54 m²
2 year old Male: 0.563 m²
5 year old Female: 0.771 m²
5 year old Male: 0.787 m²
10 year old Female: 1.245 m²
10 year old Male: 1.236 m²
13 year old Female: 1.55 m²
13 year old Male: 1.603 m²
18 year old Female: 1.726 m²
18 year old Male: 1.98 m²
20 to 79 year old Female: 1.83 m²
20 to 79 year old Male: 2.06 m²
80 years old or older Female: 1.638 m²
80 years old or older Male: 1.92 m²
