X now lets you attach up to 20 photos and videos to one post, up from four. Jonah Katz, who leads mobile engineering at X, announced the change on his own account on November 12. The new cap is five times the old one, and it counts photos and videos together.
X has allowed four per post for about 10 years. Katz put it this way: “After 10 years of Twitter/X supporting up to 4 Photos and Videos per post, the limit has been increased to 20!”
The change reached the web first
The higher limit showed up on X’s website before the mobile apps. The iPhone and Android apps are getting it too, but not every user has it yet, and some still see four. Katz’s follow-up post tells users to update the app if the option does not appear.
Big update to the X platform today After 10 years of Twitter/X supporting up to 4 Photos and Videos per post, the limit has been increased to 20! Happy posting https://t.co/8hjclgo3rk

An earlier test pointed the same way. In June, a test post from an X Developer Platform employee showed six videos attached to one post. At the time, the change had not reached general users. The new cap of 20 is more than three times that test.
What the announcement leaves out
Katz’s announcement covers only the number of attachments. It does not mention longer videos, higher upload quality, or file size limits. It also does not say whether the higher limit needs X Premium or another paid plan, which accounts get it first, or when every account will have it.
X’s public developer documentation still says a post may include up to four photos, one animated GIF, or one video, with no higher number. Apps and scheduling tools that follow those docs may keep the old limit until they update.
What it means for your posts
Four was tight for anyone posting an event. Twenty fits most photo sets from a single day, so a full photo dump can now go in one post. Instagram has allowed 20 photos or videos in one carousel since August 2024, and its carousel posts also let each slide carry its own caption.
With more items in a post, each photo or video can be marked as sensitive on its own, so check each one before you post.
To see whether the change has reached your account, try attaching a fifth photo to a new post. If the app accepts it, you have the new limit. If it stops at four, update the app and try again.
