What is Ideal Weight?

Ideal body weight is an estimate of the optimal weight for a given height. Different formulas were developed for different purposes (clinical drug dosing, general health). No single formula is universally accurate — the healthy BMI range is generally the most practical reference.

Frequently Asked Questions

Which ideal weight formula is most accurate?

No single formula is universally accurate. The BMI-based healthy weight range (18.5–24.9) is the most widely accepted reference for general health.

Should I aim for the exact ideal weight?

Ideal weight is a reference range, not a strict target. Focus on healthy habits rather than a specific number on the scale.

Does ideal weight differ by body frame size?

Yes. Some formulas account for frame size (small, medium, large). The values shown here assume a medium frame.
