Ideal Weight Calculator
A healthy target weight for your height
Get an ideal body weight estimate for your height, plus the full healthy weight range based on a normal BMI.
There's no single 'ideal'
We show the classic Devine ideal-weight figure plus the broader healthy range (BMI 18.5–24.9). A healthy weight is a range, not one number — frame, muscle and age all matter.
Where the formulas come from
"Ideal body weight" formulas like Devine were originally created to help dose medication, not to set a beauty or fitness standard. They use height and sex only, so like BMI they don't account for muscle or build — treat the single figure as a reference point inside the healthy range, not a target to chase.
A range you can actually use
For most people, anywhere in the healthy range shown is reasonable; where you feel and perform best within it is individual. If your goal is body composition rather than a scale number, pair this with the body fat calculator and focus on strength, energy and how clothes fit over time.
Ideal Weight Calculator: frequently asked questions
What should I weigh for my height?
Use the healthy range shown (based on BMI 18.5–24.9); the Devine figure is one common reference point within it.
Is muscle accounted for?
No — like BMI, these formulas use only height, so very muscular people may read 'over' their ideal.
Is ideal body weight the same as a healthy weight?
Not exactly — 'ideal body weight' is a single formula-based figure, while a healthy weight is the broader range (BMI 18.5–24.9) that suits your height. Muscle, frame size and age make the right weight a range.
