Overweight/BMI Calculator

Are you overweight? What's your Body Mass Index (BMI)? Find out right now for free!

This is a free overweight / BMI calculator script. If you are a webmaster you can download it as PHP script or Plain HTML/Javascript (with the old UI) and install it on your site very easy.

Note for visitors: If you just want to check your BMI you do not need to download and install it. Just use it right here in the site. The download-able version is for webmasters who want to have it on their sites too.

See how the calculator looks and works below. There might be small discrepancies when switching between English and Metric systems due to rounding calculations.

Overweight Calculator Installation (PHP Version)

Once downloaded the above script, unzip it and upload it somewhere in your web host. It's just one single PHP script so all you need to do is to upload it. Then put the following PHP code in your web page:

<?php require("overweight_calculator.php"); ?>

Overweight Calculator Installation (HTML/Javascript Version)

Installing this version is as easy as uploading the file on your web host. It just works. But you may want to include it as a part of existing web page. This is also easy, just follow these steps (Basic knowledge of HTML is required):

1. Copy the javascript from the header to your new page
2. Copy the HTML code of the calculator surrounded by comments
3. Copy the last javascript function call that is under the BMI calculator. Alternatively you can call this function as body's onload attribute.

You can customize the messages that the script gives or its design by modifying the file in a text editor. Look at the beginning of the script, it should be pretty easy to find them.

This script is completely free and you can do everything you want in it. There are no obligations at all. There is a link to this page at the bottom, but if you wish to remove it, that's ok (We will appreciate if you leave it there though).
