Meta Tags & Open Graph Generator

How it works

  1. 1.

    Title and description

    Pick metric (cm/kg, international) or imperial (ft-in/lb, USA). Internally the tool always computes in SI and returns the result in your chosen system.

  2. 2.

    OG image URL

    Enter height and weight. Formula: BMI = weight (kg) / height (m)². Imperial values are converted to SI before the calculation.

  3. 3.

    Copy tags

    BMI value plus WHO classification (underweight, normal, overweight, obesity I-III) with color coding and the healthy weight range for your height.

FAQ

What size should the OG image be?+

1200×630 pixels. That's the official Open Graph standard expected by Facebook, LinkedIn and X.

How long should the meta description be?+

Between 70 and 160 characters. Google truncates longer ones in the SERP snippet.

Do I need Twitter-specific tags?+

Not strictly — X falls back to Open Graph. twitter:card=summary_large_image is recommended anyway.
