It's a plain <iframe>, so it works with any site builder or CMS that accepts custom
HTML.
What you're embedding
A minimal, self-contained BMI calculator — no ads, no analytics, no tracking, no webfont download. It calculates your body mass index and healthy weight range using the same WHO thresholds and the same pure calculation code as the full BMI calculator page on this site, so the numbers your visitors see match ours exactly.
