Publishing on X (formerly Twitter)

Schedule and publish on X (Twitter)

Updated yesterday

Schedule your content on X

In Metricool, you can easily schedule your content to go out exactly when you want.
Connecting X (Twitter) in Metricool is a paid add-on and only available in Starter plans or higher. Check all the details here.

💡 Use the Best Time to Post feature to know when your audience is most active and check the image and video requirements to make sure everything looks perfect.

✏️ Key Points

  • Content: create threads (up to 80 posts).

  • Multimedia: attach images (up to 4 per post), one video, or one GIF. Mixing formats is not possible.

  • Character limit: 280 / 25,000 (X Premium — X's own subscription) per post.

  • Alt text: supported. Click the ALT button to add your alt text.

  • Mentions and tags: enter the username (for example, @metricool.bsky.social). While typing, the autocomplete function will help you select the correct name from the suggested list. You can tag other people in images.

📝 Notes

  • Links always count as 23 characters toward the total limit, no matter the actual URL length.

  • If you have X Premium (X's own subscription), you can publish using the native character limits. Keep in mind that after activating it, X (Twitter) may take around 24 hours to reflect the update in Metricool.
