Learn the formulas behind ideal weight calculations
If you know your height in feet and inches, convert it to total inches:
For a person who is 5 feet 7 inches tall:
(5 × 12) + 7 = 60 + 7 = 67 inches
This means they are 67 inches tall.
Use one of the standard formulas based on your gender:
For men: 50 kg + 2.3 kg per inch over 5 feet
For women: 45.5 kg + 2.3 kg per inch over 5 feet
For a 5'7" woman (67 inches):
45.5 + (2.3 × 7) = 45.5 + 16.1 = 61.6 kg
To convert to pounds: 61.6 kg × 2.2 = 135.5 lbs
Different formulas (Hamwi, Devine, Robinson, Miller) use slightly different calculations. Our calculator averages these formulas to give you the most accurate range.

Ideal body weight is the weight range that is considered healthiest for a person of specific height, gender, and sometimes age. It represents a weight that minimizes health risks while supporting optimal body function.
While many factors influence your perfect weight, including genetics, body composition, and lifestyle, our calculator provides a scientifically-backed starting point using multiple established formulas.
| Height | Women (lbs) | Men (lbs) |
|---|---|---|
| 5' 4" | 110 - 144 | 121 - 158 |
| 5' 7" | 122 - 159 | 133 - 174 |
| 6' 0" | 140 - 183 | 152 - 199 |
One of the oldest and most commonly used methods, especially in clinical settings.
Originally developed for medication dosage calculations, now a standard for ideal weight estimation.
A modification of the Devine formula with adjusted coefficients for different results.
Another modification that provides an alternative estimate to the other formulas.
This tool provides an estimate based on population averages. It is not a substitute for professional medical advice. Factors like muscle mass (common in athletes) and body frame size can influence your "ideal" weight. Always consult with a healthcare provider, like a doctor or registered dietitian, to discuss your personal health goals.
Common questions about ideal weight calculation
An ideal weight calculator is a tool that provides a healthy body weight range based on factors like your height, gender, and age. It commonly uses established formulas like the Robinson, Miller, Devine, and Hamwi methods to provide an estimate.
Our calculator uses medically recognized formulas to provide a scientifically based weight range. However, it's an estimate and doesn't account for individual factors like muscle mass, body composition, or frame size. For personalized health advice, always consult a healthcare professional.
No, they are different but related concepts. BMI is a measure of body fat based on height and weight that applies to adult men and women. An ideal weight calculation provides a specific weight range, while BMI categorizes your weight status (e.g., underweight, normal, overweight). Our BMI Calculator can provide additional insights.
The standard formulas used in this calculator are designed for adults. For children and teenagers, growth charts and BMI-for-age percentiles, as recommended by pediatricians, are more appropriate measures.
No single formula is universally "most accurate" as they all have limitations. That's why our calculator provides a range based on multiple formulas, giving you a more comprehensive view of your healthy weight range.
Your ideal weight calculation will only change if your height changes (which typically stops in early adulthood). However, monitoring your actual weight relative to this range is beneficial. Monthly checks are sufficient for most people unless you're actively working on weight management.
If you have a high muscle mass percentage, you may weigh more than the "ideal" range while still being healthy. In such cases, body composition measurements (like body fat percentage) provide a better indication of health than weight alone.
The standard formulas don't account for age, but some experts suggest adding 1-2 pounds per decade after age 30 to account for natural metabolic changes. However, maintaining a stable healthy weight throughout adulthood is generally recommended.
