Ideal Weight Calculator

The Ideal Weight Calculator is a comprehensive web-based tool designed to help you determine your optimal body weight using multiple scientifically recognized formulas. This calculator provides a healthy weight range based on Body Mass Index (BMI) standards and calculates ideal weight estimates using four different medical formulas: Robinson (1983), Miller (1983), Devine (1974), and Hamwi (1964).

The calculator features a modern, user-friendly interface with a purple gradient design and supports both metric (kg/cm) and imperial (lb/in) measurement systems. It’s responsive and works seamlessly on desktop and mobile devices.
