Open Graph image size guide

The practical dimensions, aspect ratio, and file-prep rules for social share images that need to preview cleanly.

This page exists because the query is stable and operational. The useful answer is fast: the dimensions, the ratio, the safe crop mindset, and the implementation note.

Recommended size

1200 × 630 px

Aspect ratio

1.91:1

Watch closely

Center-safe crops and file weight

Recommendation

Use 1200 × 630 pixels as the default Open Graph image size. Design with a center-safe composition so platform crops remain acceptable.

Basic Open Graph markup

<meta property="og:image" content="https://image4.io/social/cover.png" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />

Operational notes

  • Export a dedicated social image instead of reusing the on-page hero blindly.
  • Keep important text away from the outer edges.
  • Use a clean, readable composition at thumbnail scale.

Why this page works as pSEO

The intent is narrow and consistent. Searchers want a trustworthy reference, not an essay.

Checklist

  • Use 1200 × 630 as the default share-card size.
  • Keep text and key visuals center-safe.
  • Export a separate social asset when needed.
  • Verify the preview after publishing.

Common mistakes

  • Reusing a portrait or square hero image without checking the crop.
  • Packing too much text into the social card.
  • Ignoring preview validation after publishing changes.

Quick answers

What is the best Open Graph image size?

1200 × 630 pixels is the safest default for most web pages and social previews.

Can I reuse the article hero image as og:image?

Sometimes, but only if the crop and aspect ratio still work in social previews.
