Descripción
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.

Preguntas frecuentes
-
How do I add the calculator to a page?
-
Insert the
[gbmicalc]shortcode into any post or page, or add the “BMI Calculator” widget/block to a widget area. -
Can I switch between imperial and metric units?
-
Yes. Choose Standard (feet, inches, pounds) or Metric (centimetres, kilograms) on the settings page, or per widget.
-
How accurate is the child calculator?
-
For children and teens aged 2–20, the BMI is interpreted using the CDC BMI-for-age percentile method, which is the standard approach for that age group. It is a screening indicator, not a diagnosis.
-
Can I change the colours and size?
-
Yes. The settings page and each widget expose colour pickers (background gradient, text, button, and the active/inactive tabs) and width/height fields.
-
Does it work in the block editor and block themes?
-
Yes. Use the shortcode in a Shortcode block, or add the widget through the block-based widgets screen. It has been tested with block themes.
-
Is it available in my language?
-
The plugin ships with translations for all 24 official EU languages and is fully translation-ready; you can also translate it at translate.wordpress.org. The bundled translations are machine-assisted starting points and native-speaker contributions are very welcome.

1.3
- Redesigned the front end: modern, mobile-responsive layout, clearer active/inactive tabs, a single heading, accessible labelled fields and announced results.
- Security: fixed a stored Cross-Site Scripting (XSS) vulnerability in the
[gbmicalc]shortcode and widget (CVE-2026-8883); all attributes and saved options are now whitelisted, sanitised and escaped on output. - Security: the settings page and widget now use the WordPress Settings API and WP_Widget, with nonce and capability checks.
- Fixed the child weight-status logic (the overweight/obese categories were unreachable) and added input validation so blank, zero or negative entries no longer produce a misleading result.
- Result sentences are now self-contained, properly translatable templates.
- Replaced the legacy widget with the modern WP_Widget API; replaced WP_PLUGIN_URL and direct script/style tags with proper enqueuing; replaced the bundled colour picker with the built-in WordPress colour picker; removed bundled copies of jQuery.
- Fixed the text domain to match the plugin slug and added bundled translations for all 24 official languages of the European Union.
- Tested up to WordPress 7.0.
