## Quick Answer

Estimate body fat percentage with the US Navy circumference method. Enter height, neck and waist, plus hip for the female equation. No age, no weight and no scale: the tool takes four tape measurements and returns one percentage. The bands it reports are this page's own rather than a clinical standard.

## Definition

A body fat calculator is an anthropometric tool that estimates the percentage of a person's total body mass that is composed of adipose tissue. It typically uses the U.S. Navy Method, which requires simple tape measurements of the waist, neck, and hips (for females), alongside height and gender. While not as precise as DEXA scans or hydrostatic weighing, it provides a practical, accessible estimate for fitness tracking.

## How to Use

1. **Select your demographics** — Choose your biological gender and preferred unit system (metric or imperial).
2. **Enter basic measurements** — Enter your height. There is no age field and no weight field; the equation uses neither.
3. **Enter circumferences** — Measure and input your neck, waist, and hip circumferences using a tape measure.
4. **Read your body fat percentage** — Read the estimated body fat percentage and the band it falls in under this page's own cut-offs.

This calculator provides estimates for educational and planning purposes. Always consult a qualified professional for specific advice on financial, medical, legal, or other regulated decisions.
