Ideal Weight
Calculate your ideal weight using multiple recognized formulas.
Results
Lorentz formula (men): H − 100 − (H−150)/4. Devine formula: 50 + 2.3 × (height in inches − 60).
📐 Ideal weight formulas
Lorentz (men) = height − 100 − ((height − 150) ÷ 4)
Lorentz (women) = height − 100 − ((height − 150) ÷ 2.5)
(height in cm)
Lorentz (women) = height − 100 − ((height − 150) ÷ 2.5)
(height in cm)
📊 Ideal weight estimates by height
| Height | Men (approx.) | Women (approx.) |
|---|---|---|
| 160 cm | 57.5 kg | 56 kg |
| 170 cm | 65 kg | 62 kg |
| 180 cm | 72.5 kg | 68 kg |
💼 Ideal-weight scenarios
Man 175 cm tall
Lorentz = 175 − 100 − (25 ÷ 4) = 68.75 kg approximately.
Woman 165 cm tall
Lorentz = 165 − 100 − (15 ÷ 2.5) = 59 kg approximately.
💡 Practical tips
- Ideal weight is an approximate range, not a strict number.
- Bone structure and muscle mass affect a healthy weight.
- Treat it as a general reference; overall health matters more than one figure.
⚠️ Limits and disclaimer
- The formulas do not account for body composition.
- Consult a doctor for a full health assessment.

❓ Frequently asked questions
How is ideal weight calculated?
With formulas such as Lorentz, based on height and sex, giving an approximate range.
Is there a single ideal weight?
No, it is a range that varies with build, muscle and lifestyle.
How does it differ from BMI?
BMI classifies weight relative to height; ideal weight suggests a reference figure.
