About this plugin
BMI Adult & Kid Calculator puts a body mass index (BMI) calculator on any page of your WordPress site. Visitors enter their height and weight (and, for children, age and sex) and see their BMI, the weight category it falls in and a healthy weight range for their height.
The plugin includes two separate calculators: one for adults aged 20 and over, and one for children and teenagers aged 19 and under, where the result is based on the child’s age and sex instead of a single adult scale.
Features
- BMI calculator for adults (20 years and over) with underweight, healthy, overweight and obese categories
- BMI calculator for children and teenagers (0 to 19 years) that takes age and sex into account and shows the BMI percentile for age
- Healthy weight range for the entered height (and for the child’s age)
- Metric units, imperial units, or a unit switch that offers both
- Gutenberg block “BMI Calculator” (adult or child calculator, language and units) with a live preview
- Shortcode generator in the admin area, no coding required
- Translation-ready admin and front-end strings
- Editable labels: change any text of the calculator and add more languages from the plugin page
- Font family and text colors can be changed in the admin area
- Optional redirect to another page after the calculation
- Responsive layout that works on phones and tablets
How to use
In the block editor add the “BMI Calculator” block (Widgets category) and pick the calculator, language and units in the sidebar. Or open the “BMI Calculator” page in your WordPress admin menu, choose a language, the calculator (adult or child) and the units, then click “Generate shortcode”. Paste the generated shortcode into a page, post or shortcode block.
Examples:
[BMIAKC_adult_calc lang="English" units="metric"]
[BMIAKC_kid_calc lang="English" units="metric"]
The units attribute accepts metric, imperial or both. The id_calc attribute only needs to be set if you place more than one calculator of the same type on a page; the generator fills it in for you.
Who it is for
Health and fitness blogs, clinics, nutrition and sports coaches, schools and parenting sites that want a ready-to-use BMI calculator without a third-party embed.
