Frequently Asked Questions

How is ideal weight calculated?

Ideal weight is estimated from your height and gender using established formulas. The calculator gives a healthy weight range rather than a single exact number.

Is ideal weight the same as BMI?

They are related but different. BMI gives a category based on height and weight, while ideal weight formulas estimate a target weight range for your height.

Does ideal weight depend on body frame?

Yes. People with larger frames or more muscle may sit above the basic estimate while still being healthy, so treat the result as a general guide.
