Use a soft tape measure. Stand relaxed, breathe out, measure at the navel for waist.

BMI is a rough ratio, not a diagnosis - it doesn't know muscle from fat. Body fat % uses the US Navy tape method, accurate to within ~3% for most men. Use the number to track your direction over months, not to obsess week to week.

Body Fat & BMI Calculator for Men

The Body Fat & BMI Calculator gives you two honest numbers about where your body actually sits right now. BMI is a rough directional ratio, useful for tracking progress over months, not for obsessing week to week.

Body fat percentage, calculated using the US Navy tape method, is more precise. It tells you your real composition, not just your weight.

Measure monthly, track the direction, and let the trend tell the story.
