Ideal Weight Calculator

This calculator estimates ideal weight using several commonly cited formulas based on height and sex.

These formulas are reference tools, not medical targets. Healthy body weight can vary depending on body composition, frame size, age, and individual context.

Devine, Robinson, Miller, and Hamwi are common ideal-weight formulas. This calculator shows all four and also provides an average value for quick comparison.

These formulas are generally based on height relative to 5 feet and apply a weight adjustment for each inch above that level.

An ideal weight calculator estimates ideal body weight from your height and sex using established reference formulas. It gives you a practical starting point if you want to compare weight estimates, understand formula differences, or get a general benchmark for body weight planning.

This type of calculator is often used for health education, reference, fitness planning, and general screening. It is not a diagnosis tool and should not be treated as a strict personal target without broader context.

This calculator compares four widely used ideal body weight formulas: Devine, Robinson, Miller, and Hamwi. Each one estimates body weight from height using a slightly different method.

The formulas usually begin from a base value at 5 feet of height and then add weight for each inch above that point. Because the formulas do not use the exact same assumptions, the results are close but not identical.

Looking at all four estimates together can be more useful than relying on only one formula, especially when you want a balanced height-based reference.

To use the calculator, choose sex, choose your preferred unit system, and enter your height. The calculator then returns ideal body weight estimates from multiple common formulas along with an average value for quick comparison.

This makes it easier to compare formula outputs, understand the likely range of height-based estimates, and use the result as a reference point for planning or discussion.

Ideal weight and healthy weight are not exactly the same. Ideal weight formulas provide standardized estimates, while healthy weight depends on many other factors such as body composition, age, muscle mass, frame size, and individual health conditions.

That means a person may be healthy outside a formula-based estimate, and two people with the same height may have different healthy weight ranges in real life. This is why ideal body weight is best used as a reference rather than a rule.

Ideal body weight estimates can be useful when comparing height-based benchmarks, setting rough planning targets, reviewing formula differences, or building a starting point for further health discussions.

They can also help you understand how traditional formulas work and why different reference methods may produce slightly different answers for the same height.
