Ideal Weight Calculator
Find the classic ideal weight for your height — plus the wider healthy range where most adults thrive.
How to Use This Calculator
The Devine ideal weight is a single, somewhat muscular-friendly number. The BMI range below it gives the broader band considered healthy for your height.
- Frame size — wrap thumb and middle finger around the opposite wrist: touching = small, slightly overlapping = medium, not touching = large.
- Treat the ideal number as a guide, not a target you must hit exactly.
- Body composition matters more than the scale for health.
Frequently Asked Questions
Is the Devine formula accurate?
It is a simple clinical estimate used for dosing medication, not a health verdict. The healthy BMI range is a more useful everyday guide.
Why does sex change the ideal weight?
Women generally have less lean mass and more essential fat than men at the same height, so formulas adjust accordingly.
Does ideal weight account for muscle?
No. Very muscular people may exceed the formula yet be perfectly healthy. Use body fat percentage for a truer picture.
How do I reach a healthier weight?
Combine a moderate calorie deficit with resistance training and sufficient protein. Aim to change habits, not just the number.
Practical Example
For a woman who is 165 cm (1.65 m) tall:
- Devine ideal weight ≈ 55.9 kg
- Healthy BMI range (18.5–24.9) ≈ 50.4–67.8 kg
The BMI range gives a more realistic target window than any single formula.
