Why a BMI Calculator is an Important Health Tool

While not a diagnostic tool, a BMI calculator is an essential screening tool for several reasons:

Provides Health Awareness

Your BMI score places you in one of four main categories (Underweight, Normal Weight, Overweight, or Obesity), giving you a quick understanding of your general health status related to weight.

Helps with Goal Setting

If you're looking to lose, gain, or maintain weight, knowing your BMI provides a baseline. You can set realistic goals and track your progress over time by recalculating your BMI periodically.

A Starting Point for Health Discussions

Your BMI can be a helpful starting point for a conversation with a doctor or nutritionist about your weight, diet, and overall health plan.

Understanding Your BMI Results

Our calculator will place your result into one of these standard categories as defined by the World Health Organization (WHO):

Below 18.5: Underweight
18.5 – 24.9: Normal Weight
25.0 – 29.9: Overweight
30.0 and Above: Obesity

It’s important to remember that BMI is a general guide. For a complete health assessment, always consult with a healthcare professional.
