Ideal Weight Calculator
Estimate a healthy weight range for your height using the healthy-BMI range and the Devine and Robinson formulas, a starting reference, not a fixed goal.
“Ideal” weight is a rough guide, not a goal, it ignores muscle, frame, and body composition. A lean, muscular person can sit above these numbers and be in great shape.
The healthy-BMI range is usually the most useful target. For what your weight is actually made of, use the Body Composition tool.

Common questions
What is my ideal weight?+
There's no single ideal, the healthy-BMI range for your height is the most useful guide, but it ignores muscle and frame. A lean, muscular person can weigh more and still be very healthy.
Why do the formulas disagree?+
Devine and Robinson are older clinical estimates with different assumptions. They give a ballpark; the healthy-BMI range is usually more practical.
Should I aim for my 'ideal' weight?+
Aim for a healthy body composition, not a number. The Body Composition tool shows what your weight is actually made of, which matters more than the scale.
