About BMI Calculator
Our BMI Calculator (Body Mass Index) is a fast and reliable health utility designed to help you understand your weight in relation to your height. As one of the most widely used screening tools for weight-related health risks, BMI provides a simple way to categorize your body composition into underweight, normal weight, overweight, or obesity ranges. While it doesn't measure body fat directly, it is a valuable first step in assessing your overall health and wellness. Built with a strict privacy-first approach, all your physical data remains on your device—our tool calculates your results locally in the browser, ensuring your metrics never touch a server.
