How long does it take for Twitter to update my card?

Twitter caches card data for performance. After updating your meta tags, it can take anywhere from a few minutes to several hours for changes to appear. You can use Twitter's Card Validator or our tool to request a fresh scrape of your page.

Do my images need to be a specific size?

Yes, Twitter recommends specific sizes for card images. For Summary Cards, images should be at least 144×144 pixels. For Summary Cards with Large Image, use at least 300×157 pixels. The recommended size for best display across all devices is 1200×628 pixels.

Can I use Twitter Cards with Twitter/X Threads?

Yes, Twitter/X Cards work with threads. Each thread post can have its own card preview when shared individually. Make sure each page in your thread has proper meta tags if you want card previews for individual posts.

Are Twitter Cards supported on all platforms?

Twitter/X Cards are supported across the web, iOS, and Android platforms. However, the appearance may vary slightly between platforms, so it's always good to test your cards on different devices.

What's the difference between Twitter Card and Open Graph tags?

Twitter Card tags (twitter:card, twitter:title, etc.) are specifically for Twitter/X. Open Graph tags (og:title, og:image, etc.) are used by multiple platforms including Facebook, LinkedIn, and Twitter/X. It's recommended to include both for maximum compatibility across social platforms.

Why isn't my card showing up?

Common reasons include missing required meta tags (twitter:card, twitter:title, twitter:description), invalid image URLs, images that are too small, or your website being blocked by robots.txt. Use our validator to identify specific issues with your implementation.
