About BMI Calculator

Calculate your Body Mass Index. Find out instantly whether you are underweight, normal, overweight or obese.

BMI Calculator is part of Smart2Office's suite of free browser-based utilities. It is designed to handle everyday tasks that would otherwise require installing dedicated desktop software or subscribing to a paid service. Open the page, use the tool, and close it — there is nothing to set up and nothing to maintain.

It works on any modern device — Windows PC, Mac, iPhone, Android phone or tablet — because it runs entirely in your web browser. That also means there is no version to update, no compatibility issues between operating systems, and no licence to renew.

✅ Key Features

  • Based on globally accepted medical and fitness reference formulas
  • Instant calculation as you change inputs
  • Plain-language interpretation of results included
  • For informational guidance only — consult a healthcare professional for medical decisions

🔒 Your Privacy — All calculations are performed instantly in your browser using JavaScript. No data is sent to any server. Smart2Office does not track what you process, and we do not store any output files. What you create belongs entirely to you.
