Frequently asked questions

This tool uses the Devine formula: 50 kg + 0.91 × (height in cm − 152.4) for men, and 45.5 kg + 0.91 × (height − 152.4) for women. It also shows the healthy weight range from BMI 18.5 to 24.9.

No. Different formulas (Devine, Robinson, Hamwi) give slightly different numbers, and they ignore muscle and frame size. Treat the result as a guide, not a strict target.

A single number can be misleading. The healthy BMI range gives a band of weights that are considered healthy for your height, which is often more realistic.

Not well. Muscular people can be heavier than these formulas suggest while still being healthy, because muscle weighs more than fat. Use body composition measures instead.

What Is a Healthy BMI?

For most adults, a healthy BMI is between 18.5 and 24.9. A BMI below 18.5 is classed as underweight, 25 to 29.9 as overweight, and 30 or above as obese. BMI is a quick screening tool, not a diagnosis — it does not distinguish muscle from fat.
