Body Fat Index

Determine your body fat percentage

Use a tape measure to determine your waist, hip, and neck circumference. Then, input your gender and measurements below to receive an estimate of your body fat percentage based on standard formulas.

Please note: This body fat index is only an estimate and does not directly measure your fitness level, as it does not account for height or weight proportions the same way other assessments might.
