Ideal Weight Calculator: Find Your Healthy Weight by Height | Free

A No single formula is best. Comparing multiple formulas gives a healthy weight range.

A Yes, men and women have different ideal weight calculations due to body composition differences.

A Yes, completely free.

A The calculator uses multiple formulas to provide a comprehensive view. Devine, Robinson, Miller, and Hamwi are typically 'ideal body weight' formulas, often used in medical dosing, based on height and gender. BMI (Body Mass Index) is a widely recognized health indicator, categorizing weight into underweight, normal, overweight, and obese based on height and weight, offering a broader health context for your ideal range.

A If your current weight significantly differs from the calculated ideal weight range, it's a good prompt for action. This tool provides a guide, not a diagnosis. Consider consulting a healthcare professional or a registered dietitian. They can offer personalized advice, taking into account your individual health history, body composition, lifestyle, and goals, to help you safely work towards a healthier weight.

A Standard ideal weight formulas like Devine or Robinson primarily use height and gender, not body composition. Consequently, individuals with high muscle mass, such as athletes or bodybuilders, might find their calculated "ideal weight" seems low compared to their actual healthy weight. While BMI accounts for weight relative to height, it doesn't distinguish between muscle and fat. For muscular individuals, these calculators offer a general guideline; always consider professional health advice for a truly personalized assessment.

A These formulas were designed for adults aged 18 and over. If you're younger, your body is still growing and changing. The Devine, Robinson, Miller, and Hamwi methods won't account for adolescent growth spurts or development stages. Talk to a pediatrician instead of relying on these numbers. They'll use growth charts tailored to your age and sex.

A Each formula was developed for different populations. Devine was originally for drug dosing, Robinson came from life insurance data. So they give different numbers. For a 5'6" woman, the range might span from 120 to 140 lbs depending on which method you pick. That's normal. Look at the spread across all formulas rather than fixating on one result.

A No, you shouldn't. Pregnancy and breastfeeding change your body's needs dramatically. These formulas assume a non-pregnant adult body composition. A woman who's 5'5" and pregnant might see a 'healthy' range of 114-144 lbs from the Devine formula, but that'd be dangerously low during gestation. Your doctor uses entirely different weight-gain charts — typically 25-35 lbs for a healthy BMI pregnancy. Don't substitute this calculator for prenatal care.

A No, it shows where the formulas say you should be, not where you actually are. Enter your height and gender, and you'll get weights from five methods. A 5'9" man might see 155 lbs from Hamwi but 169 lbs from Miller. Compare those to your current weight. If you're within 10 lbs of the range, you're close. This isn't a health checkup, just a reference. Use a full BMI or body fat test for real assessment.
