Our calculators use scientifically-validated formulas and provide estimates based on the information you input. However, individual results vary due to genetics, measurement accuracy, and other factors. Calculator results should be used as guidelines, not absolute measurements. For the most accurate body composition assessment, consider professional methods like DEXA scans or hydrostatic weighing.
