Generate valid Twitter/X Card meta tags for any page, check them against X's limits and see a live preview. Supports summary, large image, player and app cards.
summary shows a small square thumbnail beside your title. summary_large_image shows a big 1.91:1 image above the title. summary_large_image gets more clicks on X because the image is more eye-catching.
Yes. Even after the rebrand to X, the meta tag names are still twitter:card, twitter:title, and so on. They haven't been renamed.
For summary_large_image use at least 300 × 157 px (1200 × 628 recommended, 2:1 or 1.91:1). For summary use at least 144 × 144 px (square). Images must be under 5 MB and JPG, PNG, WebP or GIF; X uses only the first frame of animated GIFs.
Post the link in a draft on X, or use the Open Graph Checker in Live Tools to fetch your live page and confirm the tags are present. X caches cards, so changes can take some time to appear.
X falls back to Open Graph if Twitter tags are missing, so you can get away with just OG. But adding a few Twitter-specific tags lets you choose the card style and set a different image for X if you want.
