Instagram is currently testing a new feature with some users that allows you to see how your posts will look on your profile before you publish them. This way, you can make sure that each update fits well with the overall look and style of your Instagram feed.

For example, some users have noticed a new button called “Show preview” when they are creating a post. When you tap on this button, it shows you a preview of where the post will appear on your profile grid, including any pinned posts.

This feature can help you maintain a consistent theme and vibe on your profile. It ensures that everything you post aligns with the overall approach you’re taking with your Instagram presence.

While it may not be a groundbreaking change, it’s a useful update that can help you decide what and when to post on Instagram to maximize the impact on your profile. Consistency is important in building your presence on the app, so having the ability to place your posts correctly before publishing can be valuable.

Currently, this feature is available for single images, videos, and carousel updates, but not for Reels.
