Instagram has quietly increased its carousel post limit to 20 items. That means those “photo dump” posts on your feed will now include even more images and videos. This update doubles the previous limit of 10 pieces of content that can be embedded in a single post.
Instagram Carousel Post Feature Updated
This feature has been tested for a few months and started with a limit of 15 items before expanding to 20. The new feature is already available for most users and if not, you need to update your Instagram app to the latest version.
Instagram's main competitor, TikTok, offers an even larger pool with up to 35 photos and/or videos in a single post.
