How Ideal Weight Calculator is Calculated
This calculator implements published clinical formulas for ideal weight estimation, drawn from peer-reviewed nutrition and medical research. Results are general estimates — individual factors including genetics, medical history, and lifestyle can cause significant variation. Consult a healthcare professional before making health decisions based on these outputs.
Frequently Asked Questions
Which ideal weight formula is most accurate?
The Devine formula is most widely used in clinical settings for drug dosing. For general health goals, look at the range across all four formulas — any weight within that range is considered healthy.
Is ideal weight the same as ideal BMI?
No. Ideal weight gives a single target, while BMI defines a range (18.5–24.9). Ideal weight formulas account for gender but not body composition, so muscular individuals may exceed ideal weight while still being healthy.
