How to Preview Open Graph and Social Media Link Cards

You publish a blog post and share it on Twitter. The preview card shows the wrong image, the description cuts off mid-sentence, and the title is from a completely different page. Open Graph preview tools catch these issues before your content goes live.

How the preview tool works

The ToolStand Open Graph Preview takes any URL and simulates how it will appear when shared on Facebook, Twitter, LinkedIn, and Slack. It reads the page og:title, og:description, og:image, twitter:card, and other meta tags, then renders realistic preview cards for each platform. Each platform has different image dimensions, description lengths, and layout rules — the preview shows all of them.

Common issues to catch

Missing og:image. The most common issue — without an og:image tag, Facebook and LinkedIn show a blank or default image. Wrong image dimensions. Facebook prefers 1200x630. Twitter large cards use 1200x675. A portrait image gets awkwardly cropped. Description truncation. Facebook truncates at about 200 characters, Twitter at about 200. Caching issues. Facebook caches OG data aggressively. Use the Facebook Sharing Debugger after the preview tool confirms your tags are correct.

Fixing preview issues

Use the Meta Tag Generator to create correctly sized OG and Twitter tags. Paste the generated tags into your page, then re-run the OG Preview to verify. Iterate until every platform shows the card you want.
