What Is Ideal Weight?

Ideal weight is a range of weights associated with the lowest health risk. It's not a single number because healthy bodies come in different shapes and sizes.

BMI 18.5-24.9

Generally considered healthy for most adults.

Multiple Formulas

Different formulas provide different estimates. Use as a starting point.

Body Composition
