How is ideal weight calculated?

From height and sex using four medical formulas (Devine, Robinson, Miller, Hamwi) plus the healthy BMI range (18.5–24.9).

Is ideal weight the same for everyone of the same height?

No — it depends on body composition, muscle mass and build. Use it as a guide alongside body fat percentage.

ℹ️ “Ideal weight” is an indicative concept — the healthiest weight also depends on body composition, muscle mass and overall fitness. The BMI-based range is the most reliable general estimate. Consult a doctor or dietitian if needed.

The ideal weight calculator estimates a target weight that fits your height, along with the range generally considered healthy. It provides a realistic reference point for your weight without making precise medical claims.

How the calculator works and what it’s for▾

How ideal weight is estimated

The calculator derives a weight estimate from your height using established formulas and also shows the range generally regarded as healthy. Rather than a single exact figure, it's useful to think of weight as a range.

Different methods produce slightly different results, which is perfectly normal.

What you enter and what you get

You enter your height and any other requested details, and the calculator returns your estimated ideal weight and a healthy weight range in kilograms.

The result can serve as a starting point for setting a goal.

Who it's for and why

The calculator suits anyone who wants a direction for a weight goal or wishes to check whether their current weight falls within a typical range. It's a helpful aid when planning lifestyle changes.

Important for interpretation

Ideal weight is a generalisation that does not account for individual build, muscle mass or bone structure. Treat the result as indicative and, if needed, consult a professional before making significant changes.
