X platform: Raises the per-post image and video limit from 4 to 20
X platform rolled out an update on November 12, 2026, raising the maximum number of images and videos that can be uploaded in a single post from 4 to 20. The change was publicly announced on the X platform by X Mobile Engineering Lead Jonah Katz, who said the limit had been in place for about 10 years and has now been adjusted.
Users must update to the latest version of the app to see the new limit. In follow-up posts, Jonah Katz provided update links for iOS and Android and thanked relevant team members. Some users have already tested uploading more than 4 images in a post, and the platform interface now supports displaying multiple images.
The adjustment did not disclose specific technical implementation details or whether other limits, such as file size or format, were changed at the same time. The official did not publish a separate announcement page; the information came from the original posts by platform staff.

Jonah Katz is X’s Mobile Engineering Lead and has long been responsible for client-side feature iterations. This adjustment is a direct expansion of X’s media upload capability, allowing a single post to carry more visual content, as distinct from the earlier practice of splitting images across multiple posts or threads. Since being acquired by Elon Musk in 2022 and renamed, X has continued to iterate rapidly on product features; this update is a relaxation of a client-side limit.
From a business perspective, increasing the number of media items allowed in a single post can reduce the effort users need to split posts when presenting multiple images, potentially increasing content richness and dwell time. The platform still maintains limits on individual image size (typically 5MB), and this update mainly relaxes the quantity limit rather than quality or storage-cost constraints. X did not disclose the specific impact of this feature on server load or ad display.
Comparable cases include platforms such as Instagram and Threads, which have long supported multiple images per post (usually around 10), as well as the early Twitter setting that fixed the image limit at 4. The similarity is that social media platforms enhance expressive capacity by increasing media capacity; the difference is that X raised the limit directly from 4 to 20 this time, a relatively large increase, and it was announced by the engineering lead in an original post rather than through a product changelog.
The specific change is that users can now centrally display more images or videos in a single post, reducing the need to split threads and potentially changing how creators organize content and how audiences browse. For the platform, this is a low-friction feature expansion that helps maintain competitiveness with other multi-image platforms. Observers should watch for changes in the share of multi-image posts and whether display or moderation rules for highly multi-image posts are adjusted later.

Relaxing the per-post media limit can reduce the need for users to split posts and increase content concentration.
The feature iteration was announced in an original post by the engineering lead, reflecting a direct communication style for product changes.
Raising the quantity limit does not mean other limits are relaxed at the same time; file size and format rules still exist independently.
