What is the Ideal Weight Calculator?
The Ideal Weight Calculator is an online health tool designed to calculate your optimal weight based on your height, age, and gender. Unlike single-parameter tools, it incorporates multiple established formulas to provide a range of results. This ensures you get a realistic weight estimate instead of relying on one formula alone.
It also shows the Healthy BMI (Body Mass Index) range recommended by health experts worldwide, helping you understand whether your current weight aligns with medical guidelines.
How Does the Ideal Weight Calculator Work?
Our calculator uses the following methods to estimate your healthy weight:
Peterson Formula (2016): Based on BMI midpoint (22), widely used in modern health studies.
Robinson Formula (1983): Calculates weight using linear growth in inches above 5 feet.
Miller Formula (1983): Similar to Robinson but with slightly different coefficients.
Devine Formula (1974): One of the earliest medical formulas for medication dosing and clinical use.
Hamwi Formula (1964): Traditional formula often used in nutrition and diet planning.
Healthy BMI Range: Shows the weight you should ideally fall between based on BMI values of 18.5 – 24.9.
