2026 Cross-Platform Open Graph Specification Matrix
Defined originally by the Open Graph protocol (ogp.me), a single 1200 × 630 px (1.91:1) raster image satisfies every major social feed and chat client—provided you respect file-size ceilings on mobile messengers like WhatsApp.
| Platform / Crawler | Target og:image | Max File Weight | Title / Cache Quirk |
|---|---|---|---|
| X / Twitter (Twitterbot) | 1200 × 628 / 630 px | 5 MB (JPG, PNG, WebP) | Requires twitter:card=summary_large_image; bottom-left pill overlay |
| LinkedIn (LinkedInBot) | 1200 × 627 / 630 px | 5 MB | Caches for 7 days; purge via LinkedIn Post Inspector |
| Facebook (facebookexternalhit) | 1200 × 630 px (min 600×315) | 8 MB | Purge via Meta Sharing Debugger “Scrape Again” |
| Discord (Discordbot) | 1200 × 630 px | 8 MB | Displays og:site_name, og:title, og:description + theme-color bar |
| WhatsApp / iMessage | 1200 × 630 px | < 300–600 KB recommended | Large PNGs (> 1 MB) often time out and drop the image preview |
Safe-Center Blueprint for Universal 1200 × 630 Link Cards
Keep your logo, headline, and product mockup inside the centered 1080 × 540 px safe zone so rounded card corners, X's bottom-left badge, and square mobile chat fallbacks never slice into your key message.
Open Graph Previewer — Technical FAQ
What is the universal Open Graph image size for all social platforms in 2026?+
1200 × 630 pixels (1.91:1 aspect ratio) saved as JPG or PNG under 600 KB–1 MB renders cleanly across Facebook, LinkedIn, X (summary_large_image), Discord, Slack, and WhatsApp.
Why should og:image use an absolute HTTPS URL instead of a relative path?+
Social crawlers (facebookexternalhit, Twitterbot, LinkedInBot, Discordbot) do not resolve relative paths like /og.jpg reliably; always declare full https://yourdomain.com/og.jpg URLs.
Does SVG work as an Open Graph preview image?+
No. Major social crawlers including X, Facebook, LinkedIn, and WhatsApp ignore SVG files in og:image—always export raster PNG, JPG, or widely supported WebP.
Why does WhatsApp sometimes fail to show a link thumbnail that works on X?+
WhatsApp mobile link previews time out quickly and often skip og:image files larger than ~600 KB or served with slow redirects. Compressing your 1200 × 630 JPEG under 300 KB fixes most WhatsApp preview failures.
