Healthy Weight Reference Calculator

View adult healthy-BMI weight range and a separate Devine clinical reference from height.

There's no single ideal weight. A healthy range comes from BMI 18.5–24.9 for your height; the Devine figure is a clinical dosing reference, not a target.

How this calculator works

Healthy-BMI range uses BMI 18.5–24.9. Devine was developed as a clinical dosing reference and is not a perfect target weight.

How to use your result

Keep your inputs consistent and compare weekly trends. Make small changes only after enough data accumulates.

Important limitation

Calculator results are estimates. Pregnancy, eating disorders, medical conditions, injuries, or concerning symptoms require qualified professional guidance.

Frequently asked questions

What is my ideal body weight?

Use the healthy-BMI weight range for your height as a screening reference. Your best weight depends on muscle, frame, and goals — not one number.
