- Age and gender of the person(s) to be measured.
- Physical condition of the person(s) to be measured: is the subject sedentary, highly fit, or an athlete?
- How much training you have with the skinfold measurement technique.

All equations are based on research that was conducted on different groups of individuals with a variety of ages, sex and ethnicities, which could generate discrepancies in the results according to the person to be measured using each equation, and likewise, each equation differs in the number of skinfolds to be measured:

- Less skinfold sites (2 - 3) = less time to complete, less accurate results.
- More skinfolds sites (4 - 9) = more time to complete, more accurate.
