BMI Calculator — free online tool

You step on the scale and wonder what the number really means for your height. Is it fine, a little high, a little low? Instead of guessing, we added a free tool that works it out for you — BMI Calculator — right in your browser.

What it does

You enter your height and weight, and it gives you your Body Mass Index. You can use metric (kilograms and centimetres) or imperial (pounds and feet/inches), whichever feels normal to you. It also shows the healthy weight range for your height, so you can see where you stand at a glance.

Nothing leaves your device

The whole thing runs in your browser. Your height and weight are never uploaded anywhere and nothing is saved. When you close the page, it's gone.

How to use it

  1. Open BMI Calculator and pick metric or imperial.
  2. Type in your height and your weight.
  3. Read your BMI and your healthy weight range.

It's free with no limit. There are more small tools on the Apps page.
