What is a Ideal Weight?

Ideal weight is a scientifically estimated target body weight considered optimal for a given height, gender, and body frame. Several medical formulas exist — the most widely used being the Devine Formula (1974), which was originally developed for pharmaceutical dosing but became a standard health reference. Unlike BMI which only uses height and weight, the ideal weight calculator also accounts for body frame size — small, medium, or large — recognizing that two people of the same height can naturally carry different healthy weights based on bone structure.

How to Use This Calculator

Enter your height in centimeters. Select your gender. Then select your body frame size — to determine your frame, wrap your thumb and middle finger around your wrist: if they overlap you have a small frame, if they just touch you have a medium frame, and if there is a gap you have a large frame. Click Calculate to see your ideal weight, healthy weight range, and a comparison with the BMI-based healthy weight range for your height.

💡 Pro Tips

✓Ideal weight is a range, not a single number — any weight within the healthy range is equally good.
✓Muscle weighs more than fat — strength training athletes may weigh above their "ideal" while being very healthy.
✓Never aim for a weight below the minimum of your healthy range — being underweight carries serious health risks.
✓Use ideal weight as a long-term target, not a short-term obsession — sustainable lifestyle changes matter more than the scale.
✓Combine ideal weight tracking with body fat percentage measurement for a more complete health picture.
