Ideal Weight Calculator is a free online tool that estimates your ideal body weight based on your height and gender using multiple well-known medical formulas including Devine, Robinson, Miller, and Hamwi. Rather than relying on a single formula, this tool calculates an average across all formulas to give you a more balanced estimate. Ideal weight is a general guideline — actual healthy weight depends on many factors including body composition, age, and fitness level. Always consult a healthcare provider for personalized advice. All calculations happen in your browser.
