How to Create Open Graph Images for Social Sharing
Open Graph images determine how your links appear when shared on social media. A well-designed OG image can dramatically increase click-through rates compared to a default or missing preview.
Key Takeaways
- When you share a link on Facebook, LinkedIn, Twitter, or Slack, the platform fetches the `og:image` meta tag and displays it as a preview.
- Recommended size**: 1200x630 pixels (1.91:1 aspect ratio).
- OG images are often displayed small (300px wide on mobile feeds).
- For sites with many pages, generate OG images programmatically using tools like Puppeteer, Playwright, or Pillow.
- ### Visual Hierarchy Place the most important information (headline) in the top-center area.

Text Readability
OG images are often displayed small (300px wide on mobile feeds). Use large, bold text with high contrast. Keep text to 5-10 words maximum.
Brand Consistency
Include your logo, brand colors, and consistent typography across all OG images. This builds recognition in social feeds.
Visual Hierarchy
Place the most important information (headline) in the top-center area. Some platforms crop the bottom of OG images, so avoid critical content there.
Dynamic OG Images
For sites with many pages, generate OG images programmatically using tools like Puppeteer, Playwright, or Pillow. Template your design and inject page-specific titles and descriptions.
