Meta Tags & Open Graph Generator
How it works
- 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.
OG image URL
Enter height and weight. Formula: BMI = weight (kg) / height (m)². Imperial values are converted to SI before the calculation.
- 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.
