SketchAndCalc is often used in the medical community as a Body Surface Area Calculator. Whether to calculate a persons somatotype or just to compute the total surface area of a human body, referred to as body surface area or BSA.
Direct measurement of BSA can be difficult, most surface area calculators employ formulas that offer approximations of a persons BSA by inputting a persons sex, weight, and height.
Uniquely, SketchAndCalc calculates surface area accurately by tracing the perimeter of a persons silhouette. Providing the drawing scale is set using a known measurement, such as the persons height.
