Instagram has quietly increased the limit for carousel posts to 20 items. This means that the “photo dump” posts in your feed will now include even more images and videos. This update doubles the previous limit of 10 pieces of content that can be included in a single post.
Updated Instagram Post Carousel Feature
The feature was tested for a few months and was initially limited to 15 items before being expanded to 20. The new feature is now available to most users, and if not, you should update your Instagram app to the latest version.
Instagram’s main competitor, TikTok, offers an even larger pool — up to 35 photos and/or videos in a single post.
