Creating Content for X (Twitter)

In this article 

Supported Formats

  • MP4, MOV, JPG, PNG, GIF
  • Max image size: Between 3MB and 5MB.
  • Video posts: Up to 512MB and 140 seconds long. The video duration has a hard limit, so you can’t upload videos with a fraction of a second over the time limit.
  • The character limit is 280 for English, Spanish, and Portuguese.

Post Types

You can create and schedule photo (up to 4 images per post), video, and link posts.

Editing photos


All the photos or creative assets you upload for your post will appear in the media tray. From the media tray, you can add or remove them from the post. The images that appear on top of the media tray are the ones that will be published in the post. 

  • To remove a photo, click the [X] in the top-right corner. This will remove it from the preview, but it will still be in the media tray in case you change your mind and want to include it again. To add a different photo to the post, select it from the media tray. 
  • To edit a photo, hover over it and click on the three dots in the left corner. With Gain's photo editor, you can crop, resize, add text, and apply effects to your images.

Important: Our upload limit is set at 5MB. However, occasionally, X may not accept images larger than 3MB. Should this happen, you'll get an alert. Please reduce the image size to under 3MB before you try to schedule or publish again.


Link Posts

X cards are special tweets that contain a title, description, and preview image from linked websites. X fetches these details, and they are not considered a post type.

To create an X Card, follow these steps:

  1. Choose the Status post format.
  2. Write a caption.
  3. Paste the link in the caption.

After posting your tweet, the X card should be visible. If it is missing, the linked website likely needs to enable X cards.

  • Opt for the Photo format for more control over the displayed image. Use Twitter's URL validator to preview how your tweet will appear before posting.

Important: X will only show details from a linked website if your website supports X Cards. For more information, check out X's official guide.
