Calculate your ideal body weight using proven medical formulas. Get personalized results based on your height and gender with multiple calculation methods.
This calculator uses four established medical formulas to estimate your ideal body weight based on your height and gender. Simply enter your height in either imperial (feet and inches) or metric (centimeters) units, select your gender, and click calculate to see your results.
The calculator provides results from multiple formulas along with a healthy weight range based on BMI guidelines, giving you a comprehensive view of your target weight.
One of the most widely used formulas, originally developed for calculating drug dosages. It's considered the standard in many medical settings.
Men: 50 kg + 2.3 kg per inch over 5 feet
Women: 45.5 kg + 2.3 kg per inch over 5 feet
A modification of the Devine formula that tends to give slightly higher results for taller individuals.
Men: 52 kg + 1.9 kg per inch over 5 feet
Women: 49 kg + 1.7 kg per inch over 5 feet
Another variation that provides results between the Devine and Robinson formulas.
Men: 56.2 kg + 1.41 kg per inch over 5 feet
Women: 53.1 kg + 1.36 kg per inch over 5 feet
One of the earliest formulas, still used in clinical settings for quick estimates.
Men: 48 kg + 2.7 kg per inch over 5 feet
Women: 45.5 kg + 2.2 kg per inch over 5 feet
In addition to the ideal weight formulas, this calculator provides a healthy weight range based on Body Mass Index (BMI) guidelines. A BMI between 18.5 and 24.9 is generally considered healthy for most adults.
The healthy weight range gives you a broader target window, recognizing that ideal weight can vary based on factors like muscle mass, bone density, and body composition. Many healthy individuals fall within this range rather than at a single "ideal" number.
People with larger bone structures naturally weigh more than those with smaller frames at the same height. These formulas don't account for frame size variations.
Athletes and individuals with high muscle mass may weigh more than the calculated ideal weight while still being very healthy. Muscle weighs more than fat by volume.
These formulas were developed for adults and may not be appropriate for children, teenagers, or elderly individuals. Body composition changes naturally with age.
Different ethnic groups may have different body compositions and health risks at the same BMI or weight. These formulas were developed primarily using Western populations.
Your ideal weight should support your overall health, energy levels, and quality of life. Numbers are just one piece of the puzzle.
The ideal weight calculations provide a general guideline, not an absolute target. Here's how to interpret and use your results:
While these formulas are useful tools, they have important limitations:
Use these calculations as a starting point for discussions with healthcare providers, not as definitive targets. Your ideal weight is the weight at which you feel healthy, energetic, and can maintain a balanced lifestyle.
