Open Graph & Social Card Previewer: the complete guide
An Open Graph and Social Card Previewer simulates how your web pages will appear when shared across Twitter / X, LinkedIn, and Facebook feeds. Social media algorithms favor posts with rich media cards over plain text links. When social crawlers encounter missing or malformed og:image, og:title, or og:description meta tags, links render as blank gray boxes with drastically reduced click-through rates. This tool provides instant multi-platform visual mockups and generates complete, copyable HTML head meta tags.
Recommended Dimensions for Social Media Open Graph Images
The universal standard dimension for og:image tags is 1200 × 630 pixels (an exact 1.91:1 aspect ratio). Designing cards at this resolution ensures crisp high-DPI display on Twitter Large Summary Cards, LinkedIn feed updates, and Facebook link posts without unwanted cropping or letterboxing.
Essential Meta Tag Checklist for Production Sites
Every modern webpage should declare: og:type ('website' or 'article'), og:url (canonical URL), og:title, og:description, og:image, and og:site_name. For Twitter specifically, adding twitter:card ('summary_large_image') tells Twitter's crawler to render the large banner layout rather than the tiny thumbnail.
