OG Image Dimensions

Checks that og:image is ≥ 1200×630 — optimal for all social platforms.

What this check measures

We fetch the og:image and check dimensions. 1200×630 is the LinkedIn + Facebook + Slack standard. Smaller images get cropped or pixelated; much larger wastes bandwidth.

Why it matters

Wrong OG dimensions mean ugly previews: square image cropped awkwardly, small image pixelated, oversize wastes load time. 1200×630 is the universal sweet spot.

How our audit detects it

Fetch og:image, inspect binary header for dimensions. Flag if under 1200×630 or non-16:9 aspect.

Typical findings

  • error_outlineog:image is 400×400 (square) — LinkedIn/Slack crop awkwardly.
  • error_outlineog:image is 800×420 — below threshold, pixelated on retina.

How to fix

Use exactly 1200×630 (or 2400×1260 for Retina). PNG for crisp text, JPEG for photos. Under 1MB file size. Use an OG image generator (og-image.vercel.app or similar) for consistent templates.
