Body Surface Area

Body Surface Area or BSA is the total surface area of the human body. Our Body Surface Area Calculator is a tool to determine the BSA in your body.
The body surface area is used in many measurements in medicine including the calculation of drug dosages and the volume of fluids to be administered intravenously. In other words, the BSA is the measured or calculated surface area of a human body.
For many clinical purposes, BSA is a better indicator of metabolic mass than body weight. This is less affected by abnormal adipose mass.
