About this calculator

What is the Ideal Weight Calculator – target weight?

The Ideal Weight Calculator calculates the estimated target weight based on height using several formulas. The formulas (Devine, Hamwi, Robinson, Miller) provide slightly different results – the calculator shows all for comparison.

The calculator is completely free, works directly in the browser, and does not store personal data. All calculators on this site are based on up-to-date information.

Calculation Principle

Devine (male): 50 + 2.3 × (height(cm)/2.54 − 60). Devine (female): 45.5 + 2.3 × (height(cm)/2.54 − 60).

Enter your measurements in the calculator fields and press the calculate button – the result appears immediately. You can try different values to compare various scenarios.

Practical Example

Female, 170 cm → Devine 62.5 kg, Hamwi 61.1 kg, Robinson 60.5 kg, Miller 59.8 kg. Range 59–63 kg.

The result is an estimate – for accurate clinical measurements, consult a healthcare professional.

Purpose of the Calculator

The calculator is suitable for self-directed health monitoring, training planning, and general health literacy. Tracking values over time provides valuable information about body changes.

Remember that a single measurement result does not tell the whole story – what matters more is the direction and trend over multiple measurement periods.

Practical Tips

  • Use ideal weight as a guideline, not a strict goal.
  • A weight goal is more realistic when it falls within the BMI range of 20–23.
  • Weight fluctuates ±4.41 lb daily due to fluid and food – do not weigh yourself every day.
