Open Graph Image Size: 1200 x 630
The recommended Open Graph (og:image) size is 1200 x 630 pixels, a 1.91:1 aspect ratio. This is the universal link-preview size that Facebook, LinkedIn, Slack, WhatsApp and X (as summary_large_image) all render cleanly, so a single 1200x630 asset covers every messaging and social channel. Drop an image below and crop it to 1200 x 630 in your browser - nothing is uploaded.

Platform scrapers read the og:image tag from your raw HTML and pre-allocate a card of this exact ratio. A 1200x630 image fills the card edge to edge with no letterboxing, and staying above 600px wide keeps it from being rejected as a tiny fallback thumbnail.
Common mistake: The most common mistake is shipping the image without og:image:width and og:image:height tags. Without them the scraper cannot size the card on the first share and shows a blank preview until it re-fetches. This tool gives you a copy-ready <meta property="og:image"> block with matching dimensions so the card renders on the very first share.
Frequently Asked Questions
1200 x 630 pixels (1.91:1). This is the recommended og:image size for Facebook, LinkedIn, Slack, WhatsApp and X. Keep the important content inside a centered 1080 x 600 safe zone so nothing is clipped on mobile.
The usual causes are a relative (not absolute) image URL, missing og:image:width / og:image:height tags, or metadata injected by client-side JavaScript that scrapers do not run. Serve absolute URLs in server-rendered HTML with explicit dimensions.
