How to Use the Ideal Weight Calculator
Ideal weight is not considered to be a fixed value but rather a healthy weight range that is determined by height, sex, body shape, and health of an individual. Various formulas have been developed by medical professionals based on studies and observation to calculate ideal body weight. The Ideal Weight Calculator integrates various accepted medical equations and compares them with healthy BMI levels. This approach enables a more accurate and truthful representation of what your healthy weight ranges might be, as opposed to tracking specific numbers.
How to Use
1. Select Measurement Units
You can opt for either metric units (centimeters and kilograms) or US units (feet, inches, and pounds), according to your preference.
2. Enter Personal Information
Enter your gender. Enter your age. Both make the estimated weights more accurate.
3. Input Your Height
Enter your actual height measurements. Height is the most critical element when calculating ideal body weight.

Frequently Asked Questions
What is an ideal weight?
Ideal weight is an estimated body weight range associated with the lowest health risk. It is calculated using established medical formulas based on height and gender.
Which formulas does this calculator use?
This calculator uses four widely recognized formulas: Hamwi, Devine, Robinson, and Miller. Each formula provides a slightly different estimate based on medical research.
Why do different formulas give different results?
Each formula was developed using different populations and assumptions. Differences are normal, and the results should be viewed as a healthy range rather than a single exact number.
What is the healthy BMI range?
The healthy BMI range is 18.5 to 24.9, as defined by the World Health Organization. This calculator converts that range into a healthy weight range for your height.
Does body frame size affect ideal weight?
Yes. People with larger body frames tend to have higher healthy weights, while smaller frames may have lower healthy weights. Wrist size is commonly used to estimate frame size.
Is ideal weight the same as goal weight?
Not necessarily. Ideal weight formulas provide general guidance. Your personal goal weight should also consider muscle mass, fitness level, and medical advice.
Can I use this calculator for children?
This calculator is designed for adults. For children and teens, growth charts and pediatric BMI percentiles should be used instead.
