Open Graph Image Size Guide (2026)

The most reliable Open Graph image size is 1200 × 630 pixels at an aspect ratio of roughly 1.91:1. This is the de facto standard for large link previews across Facebook, LinkedIn, Slack, and most crawlers that read og:image.

Recommended specs

| Property | Recommendation | |----------|----------------| | Dimensions | 1200 × 630 px | | Aspect ratio | 1.91:1 | | Format | JPG or PNG | | Max file size | Under 1 MB | | URL | Absolute HTTPS URL in og:image |

Safe zone for text and logos

Platforms crop previews differently. Keep headlines, logos, and CTAs in the center 80% of the image. Avoid placing critical content at the edges — especially the top and bottom on mobile shares.

Platform-specific notes

• Facebook & LinkedIn — Both favor large landscape images. LinkedIn officially suggests 1200 × 627 px, which is close enough to 1200 × 630.
• X (Twitter) — Set twitter:card to summary_large_image and mirror your OG image in twitter:image.
• WhatsApp & Discord — Use the same og:image. Discord also displays og:site_name above the title.
• iMessage — Pulls Open Graph tags; undersized images may appear blurry when scaled up.

Common mistakes

1. Relative image paths — og:image must be a full URL (https://example.com/og.jpg).
2. Blocked crawlers — Firewalls, bot protection, or login walls prevent platforms from fetching your image.
3. Wrong aspect ratio — Portrait or square images get cropped aggressively in landscape cards.
4. Huge file sizes — Slow responses cause crawlers to time out and skip the image.

Quick validation workflow

1. Export at 1200 × 630 px.
2. Upload to a public, cacheable URL.
3. Add og:image, og:title, og:description, and og:url.
4. Scan the live URL with OpenGraph Check before publishing.

A correctly sized OG image is the single highest-impact improvement you can make for link click-through rate.
