Which formula is most accurate?

No single formula is perfect. We show results from multiple formulas (Hamwi, Devine, Robinson, Miller) so you can see the range.

Is ideal weight the same as healthy weight?

Not necessarily. Ideal weight formulas are based on statistical averages and don't account for muscle mass, bone density, or individual body composition. Use them as a general reference alongside BMI and body fat percentage.

What if I am significantly above or below my ideal weight?

A gradual approach is safest. Aim for 0.5–1 kg per week of weight loss or gain. Consult a doctor or registered dietitian before making significant dietary changes, especially if the difference is large.

About Ideal Weight Calculator

Everything you need to know about this tool and how to get the most out of it.

What is Ideal Weight Calculator?

An Ideal Weight Calculator estimates a healthy target weight based on your height, gender, and body frame size using multiple validated medical formulas. It provides a personalized range rather than a single number, reflecting individual variation in bone density, muscle mass, and metabolism. This is more realistic than BMI alone because it accounts for frame differences.

How Ideal Weight Calculator Works

Enter your height in centimeters, select your gender, and specify your body frame size (small, medium, or large). The calculator applies four established clinical formulas developed for medical use: Robinson, Miller, Devine, and Hamwi. Each formula produces a slightly different result based on different assumptions. Frame size adjusts the results by ±10%, accounting for skeletal variation. You'll see results from each formula plus an average.

Why Use Ideal Weight Calculator?

Ideal weight is a useful health benchmark for setting personal fitness goals and discussing targets with healthcare providers. Multiple formulas provide a range because there's no single 'perfect' weight for everyone. This tool helps you avoid over-relying on BMI alone, which can be misleading for athletes with high muscle mass. Understanding your target weight range is essential for creating realistic health and fitness plans.

Tips & Best Practices

1Ideal weight formulas were developed for clinical use and may not reflect athletic builds
2Muscle weighs more than fat — athletes may weigh more than 'ideal' while being very healthy
3Focus on body composition (fat vs muscle) rather than weight alone for the best health picture
