How it’s calculated: Devine: 50 (men) / 45.5 (women) kg + 2.3 kg per inch over 5 ft. Estimates for educational use — not medical advice.
Frequently asked questions
- What is my ideal weight?
- There’s no single ideal weight — a healthy range for your height (BMI 18.5–24.9) is more useful than one number. Body composition and health markers matter more than the scale alone.
- How is ideal weight calculated?
- This uses the Devine formula (a height-based clinical estimate) plus the healthy BMI weight range for your height.
- Should I aim for my ‘ideal’ weight?
- Use it as a rough guide, not a hard target. Very muscular people can be heavier and perfectly healthy; focus on habits, strength and how you feel.
