Frequently Asked Questions
We use the Devine Formula: Male: 50 kg + 0.9 kg per cm above 152.4 cm. Female: 45.5 kg + 0.9 kg per cm above 152.4 cm. A ±2.5 kg range is considered healthy.
Not always. Ideal weight from the Devine formula may give slightly different results than the BMI-based healthy weight range (BMI 18.5–24.9). Both are guidelines, not strict rules.
Men typically have more muscle mass and denser bones than women, so their ideal weight is higher at the same height. The Devine formula accounts for this biological difference.
Being underweight can indicate malnutrition, eating disorders, or underlying health conditions. Consult a doctor or dietitian if you are significantly below the ideal weight range.
Being above ideal weight doesn't automatically mean you are unhealthy — muscle mass, bone density, and body composition matter too. Consult a healthcare professional for personalized advice.
This calculator is designed for adults. For children and adolescents, BMI-for-age percentile charts (from WHO or CDC) are the appropriate reference tool.
