Twitter Card Generator
Build custom Twitter Card meta tags for better tweet previews.
Twitter Cards
Twitter Cards are meta tags that control how links appear when shared on X (Twitter). Without them, links show as plain text; with them, they show rich previews with an image, title, and description.
Card Types
- summary — small square thumbnail (minimum 144×144px) with text
- summary_large_image — large banner image (1200×600px) — most common
- app — links to a mobile app with ratings and install button
- player — embeds audio or video content directly in the card
Essential Twitter Card Tags
twitter:card— card type (required)twitter:title— title (max 70 chars)twitter:description— description (max 200 chars)twitter:image— image URL (HTTPS required, under 5MB)twitter:site— website's Twitter handle (e.g.,@yourbrand)twitter:creator— author's Twitter handle for article cards
How do I validate my Twitter Card?
Use the Card Validator at cards-dev.twitter.com/validator — paste your page URL to preview how it will appear. Note: Twitter now requires your domain to be approved and the page to be publicly accessible. Cards are not shown for private/login-gated pages.
Do Twitter Cards affect my tweet's reach?
Tweets with large image cards typically receive higher engagement — more clicks, retweets, and likes — compared to plain text links. Twitter's algorithm considers engagement signals, so indirectly, attractive cards can increase organic reach. Summary large image cards are the highest-impact format for most content types.
Can I use the same image for OG and Twitter?
Yes — if twitter:image is not specified, Twitter falls back to og:image. Many sites only implement OG tags and let Twitter use the fallback. If you set both, you can use different aspect ratios: OG prefers 1.91:1 (1200×630), Twitter large image prefers 2:1 (1200×600).
