Andreas Ostheimer

Global Body Mass Index Calculator adds a clean, responsive Body Mass Index calculator to your WordPress site. Visitors can work out the BMI for an adult or a child, switch between imperial and metric units, and see a clear, plain-language result — all without leaving your page.
Drop it anywhere with the <code>[gbmicalc]</code> shortcode or the “BMI Calculator” widget/block.

<li>Separate calculators for adults and children, on two tabs.</li>

<li>Plain-language result with the weight-status category — and, for children, the BMI-for-age percentile.</li>
<li>Colour-customisable (card, text, tabs and button) through the built-in WordPress colour picker, with an adjustable size.</li>
<li>Responsive layout that adapts from desktop to mobile.</li>

How the categories are determined
<ul>
<li>Adults: the standard WHO BMI ranges (underweight, normal, overweight, obese).</li>
<li>Children and teens (2–20 years): the BMI is interpreted against CDC BMI-for-age percentiles.</li>
</ul>
