# Free Twitter Card Validator

> Preview the X card of a URL before you post it.

Canonical: https://bannerify.co/tools/twitter-card-validator

Enter a URL to see the X card it gets: the large image card with twitter:card set to summary_large_image, or the small summary card.

X removed the preview from its own Card Validator in 2022. The large card needs an image of 2:1, at least 300 × 157 and under 5 MB, in JPG, PNG, WEBP, or GIF. No account needed.
