What is my ideal weight?

The most useful answer is a healthy weight range for your height, based on a BMI of 18.5 to 24.9. This tool shows that range plus the classic Devine, Robinson and Miller formula estimates, which give a single target figure by sex and height.

Is ideal body weight accurate?

Ideal-weight formulas are rough guides — they do not account for muscle mass, frame size or body composition. Use the healthy BMI range as a target zone rather than an exact number, and consider body-fat percentage too.

What is 'ideal weight'?

There's no single perfect number. The most useful target is a healthy weight range for your height, based on a BMI between 18.5 and 24.9. Classic formulas (Devine, Robinson, Miller) give a single figure by sex and height, which this tool averages for you.
