What is twitter:image?
The twitter:image meta tag specifies the image shown in X/Twitter link previews. Combined with twitter:card, it creates a rich visual preview that dramatically increases engagement.
Fallback behavior
X/Twitter checks for images in this order:
twitter:image— Highest priorityog:image— Falls back to Open Graph- No image — Shows a minimal text-only preview
If both twitter:image and og:image are missing, your link will appear as a plain URL or minimal card with no image — a significant missed opportunity.
Impact on engagement
- Tweets with images get 150% more retweets than those without
- Cards with large images get 40% more clicks than summary cards
- Visual content is processed 60,000x faster by the brain than text
How to fix it
<meta name="twitter:image" content="https://yoursite.com/twitter-image.jpg" />Image requirements for X/Twitter
For summary_large_image:
- Recommended: 1200 x 600px (2:1 ratio)
- Minimum: 300 x 157px
- Maximum file size: 5MB
- Formats: JPG, PNG, WebP, GIF (first frame only)
For summary:
- Recommended: 240 x 240px (1:1 ratio)
- Minimum: 144 x 144px
Best practices
- Use absolute HTTPS URLs —
https://yoursite.com/image.jpg - Optimize for 2:1 ratio — Different from og:image's 1.91:1 ratio
- Consider separate Twitter images — The slightly different aspect ratio means your OG image may be cropped differently
- Keep text minimal and large — The image may be displayed small on mobile
- Test with Card Validator — Always preview before publishing
Why use a different image for Twitter?
The recommended aspect ratios differ:
- og:image: 1200 x 630 (1.91:1)
- twitter:image: 1200 x 600 (2:1)
If you use the same 1200x630 image, X may crop the top and bottom slightly. For most images this is fine, but if your design has content at the edges, consider creating a separate Twitter-optimized version.
