1200×630 is the Open Graph size — the picture that appears when a link to your page is pasted into a message, a post or a chat. It is not really a social media image; it is part of your page's metadata, declared in the HTML with an og:image tag and read by everything from Facebook to Slack to WhatsApp.
Why 1.91:1
The ratio comes from Facebook and was adopted almost everywhere else, which is what makes it useful: one image at 1200×630 renders correctly across most platforms rather than needing a version each. Some clients crop it to a square for small previews, so keep the subject centred.
Keep it light and legible
Preview images are fetched by a scraper before your page renders, and several platforms skip anything too large. Staying under a few hundred kilobytes is safer than pushing resolution. If the image carries the page title as text, set it large — in a chat app the preview may be only a couple of hundred pixels wide.

Frequently asked questions
- What is an OG image?
- The image a site declares for link previews, using the Open Graph og:image tag. 1200×630 is the standard size.
- Do I need a separate image for Twitter?
- Usually not. X reads Open Graph tags as a fallback, and 1200×630 works for its large summary card.
- Why doesn't my preview update?
- Platforms cache preview images aggressively. Most offer a debugging tool that forces a re-scrape of the URL.
