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 [gbmicalc] shortcode or the “BMI Calculator” widget/block.

Features

Separate calculators for adults and children, on two tabs.
Imperial (feet, inches, pounds) or metric (centimetres, kilograms) units.
Plain-language result with the weight-status category — and, for children, the BMI-for-age percentile.
Colour-customisable (card, text, tabs and button) through the built-in WordPress colour picker, with an adjustable size.
Responsive layout that adapts from desktop to mobile.
Works both as a shortcode and as a widget/block.
Translation-ready, with bundled translations for the 24 official languages of the European Union.
Accessible markup: labelled fields, results announced to screen readers, keyboard-friendly tabs.

How the categories are determined

Adults: the standard WHO BMI ranges (underweight, normal, overweight, obese).
Children and teens (2–20 years): the BMI is interpreted against CDC BMI-for-age percentiles.
