Mifflin-St Jeor is the best BMR formula for most people (±5% error). Katch-McArdle is better if you know your body fat % (±3%). Harris-Benedict overestimates by 5–8%. See the decision tree and real calculation examples.
Read guideEvery body fat calculator has a real error margin. DEXA ±1-2%, skinfold ±3-5%, Navy tape ±3-4%, BIA scales ±4-8%, BMI estimate ±5-8%. See the full comparison with academic sources and learn which method to trust.

Read guideWhen your measurements fall between hourglass and pear, or rectangle and hourglass, most calculators give conflicting answers. This decision tree uses exact ratio thresholds (waist-to-hip, shoulder-to-hip, shoulder-to-waist) to resolve every boundary case with specific numbers.
Read guideHourglass needs WHR ≤ 0.75 AND shoulder-to-hip ratio 0.90–1.10. Pear needs SHR < 0.92. Inverted triangle needs SHR > 1.12. Rectangle needs WHR 0.76–0.85 with SHR 0.95–1.05. See all exact thresholds.
