Ideal Weight Calculator

Healthy weight range from height, with reference formulas.

ideal-weight-calculator.local
Enter your height to see a healthy weight range.

Overview

Estimates a reference body weight for your height using an established formula. It shows a healthy weight range for your height alongside classic formula estimates, which is more useful than treating any single number as a target.

How it works

The tool's main output is a healthy weight range derived from the normal BMI band (18.5 to 24.9) for your height, which reflects that healthy weight is a span, not one figure. It also shows reference estimates from established formulas, including Devine, which starts at 50 kg for men and 45.5 kg for women and adds about 2.3 kg per inch above 5 feet, and Robinson, a similar height-based equation. These formulas originated decades ago and each gives a single number, so use them as context next to the range rather than as a fixed goal.

How to use it

  1. Select your sex and choose your units.
  2. Enter your height.
  3. Read the estimated reference weight.
  4. Compare it with a healthy range rather than treating it as one fixed goal.

Examples

Healthy range

For a given height, the tool shows the weight span that falls in the normal BMI band, so you can see the range rather than one number.

Formula reference

A man who is 5 ft 10 in is 10 inches over 5 feet, so the Devine estimate is 50 plus 2.3 times 10, about 73 kg, shown alongside the range for context.

FAQ

Is there one ideal weight?
No. The formula gives a single number, but a healthy weight is a range. Body composition and individual factors matter more than hitting an exact figure.
Where do these formulas come from?
Equations like Devine and Robinson were developed for clinical use, such as medication dosing, and were later adopted as general references. The tool shows them next to a BMI-based healthy range.
Should I aim for this exact weight?
Treat it as a reference, not a goal. For personal targets, talk to a doctor or dietitian.
Why do men and women differ?
The formulas use different starting values to reflect average differences in body composition.
Is my data uploaded?
No. The calculation runs in your browser.
