🎚️ Ideal Weight Calculator

How It Works

Calculate ideal body weight ranges based on height and gender using the Devine formula. Use Ideal Weight Calculator as a general estimate from the measurements and assumptions you enter.

The result is most useful when the inputs match the definitions used by this calculator. For this tool, the underlying method is: Devine Formula: Men = 50 + 0.9×(height(cm) - 152). Women = 45.5 + 0.9×(height(cm) - 152). Compare the output with the worked example, then change one meaningful input at a time to see how the result responds.

Understanding Ideal Weight

Ideal Weight is a general health or fitness estimate based on the measurements and assumptions requested by the calculator.

Keep in mind: Health estimates are not diagnoses and can differ from an individual's actual needs or measurements. Review the ideal weight inputs and units before relying on the result.

When to Use This Calculator

Use Ideal Weight Calculator as a general estimate from the measurements and assumptions you enter.

Practical tip: For this Ideal Weight Calculator, use the result as a starting estimate and change one measurement or activity assumption at a time so you can see how sensitive the estimate is.

Formula

Devine Formula: Men = 50 + 0.9×(height(cm) - 152). Women = 45.5 + 0.9×(height(cm) - 152)

Example

For a 170cm male: Ideal weight = 50 + 0.9×(170-152) = 66.2 kg. Range: 66.2 - 72.8 kg.

Frequently Asked Questions

What does the Ideal Weight Calculator estimate?+

The calculator applies the method shown on the page to the health or fitness inputs you provide. It is an estimate, not a measurement of every aspect of an individual’s health.

Can two people with the same ideal weight calculator result have different needs?+

Yes. Formulas simplify complex individual factors, so the same calculated value does not necessarily imply the same needs or health status.

How should I interpret the ideal weight calculator result?+

Use it as a general informational estimate and consider the assumptions behind the formula. For medical concerns or personal treatment decisions, appropriate professional guidance is more reliable than a calculator alone.
