Open Graph requirements by platform
One og:image has to survive Facebook, X, LinkedIn, Slack, Discord, WhatsApp, iMessage and Telegram. These are the sizes and minimums each parser actually enforces, and how to force a refresh when a preview goes stale.
| Platform | Best image | Minimum | Ratio | Refresh cache |
|---|---|---|---|---|
| 1200 × 630 | 200 × 200 | 1.91:1 | Sharing Debugger → Scrape Again | |
| X / Twitter | 1200 × 628 | 300 × 157 | 1.91:1 | Preview in a draft post |
| 1200 × 627 | 200 × 200 | 1.91:1 | Post Inspector | |
| Slack | 1200 × 630 | 400 × 200 | 1.91:1 | Re-unfurl; server cache ~30 days |
| Discord | 1200 × 630 | 300 × 200 | 1.91:1 | Append a query string |
| 1200 × 630 | 300 × 300 | 1.91:1 or 1:1 | No public tool | |
| iMessage | 1200 × 630 | 400 × 200 | 1.91:1 | No public tool |
| Telegram | 1200 × 630 | — | 1.91:1 | @WebpageBot |
Minimums are per-platform hard floors: below them the parser silently drops the image and renders a text-only card. Card titles are truncated at roughly 60–90 characters and descriptions at 110–200, so lead with the specifics.
The seven failures behind most broken previews
These account for nearly every "why is my link blank?" report. Check them in this order.
1 · A relative og:image path
Crawlers resolve content="/og.png" against nothing — there is no page context at unfurl time. The card renders with no image. Always emit an absolute URL including the scheme.
<meta property="og:image" content="https://example.com/og.png" />2 · An image smaller than 200 × 200
Facebook and LinkedIn drop thumbnails below the floor entirely rather than upscaling them. A 32 px favicon reused as og:image produces a text-only card on every platform.
3 · WebP or AVIF where a JPEG was expected
Modern formats work on Facebook and X, but older scrapers and some Slack surfaces fail to decode them and fall back to a bare link. Ship JPEG or PNG for the card and keep the modern format for the page itself.
4 · Several og:image tags, first one wrong
Platforms take the first declaration, not the best one. A CMS that injects a site-wide default before your per-page image wins the race every time — the preview shows the generic logo instead of the article image.
5 · An image behind a redirect or a login
Scrapers follow redirects inconsistently and never send cookies. An image URL that 302s to a CDN, or that sits behind authentication, looks like a 404 to the crawler.
6 · A title rendered from an unpopulated template
Preview cards showing exactly "Home" or "undefined" are the classic symptom of an SPA that sets og:title client-side. Crawlers don't run your JavaScript — the tags must be in the server-rendered HTML.
7 · Tags correct, cache stale
The most common false alarm. Facebook caches an unfurl for about 30 days; if you fixed the tags an hour ago, the old card is still what people see. Refresh it in the Sharing Debugger before assuming the fix failed.
How to force a stale preview to refresh
Facebook / Instagram. Open the Sharing Debugger, paste the URL, press "Scrape Again". The first press refreshes the cache; the second confirms the new tags were parsed.
LinkedIn. Open Post Inspector, paste the URL, press Inspect. LinkedIn refreshes asynchronously — the share composer may still show the old card for a few minutes.
X / Twitter. There is no public validator left. Paste the link into a new post draft and watch the card update in the composer; nothing is published until you send it.
Slack. Remove the message and repost, or use "Remove preview" then paste again. Slack holds unfurls server-side for around 30 days with no per-URL invalidation, so a changed ?v= query is often the only reliable reset.
Discord. Append any query string (?v=2) to the shared URL — Discord keys its embed cache on the full URL, so a new string is a new entry.
Telegram. Send the link to @WebpageBot and it re-fetches the page, then reports back which tags it found.
After any change, re-run the check above: it fetches the live HTML the same way a crawler does, so a green card here plus a manual refresh there is the complete loop.
