Max Length of an Instagram Caption: 2,200 characters. With a maximum of 2,200 characters, Instagram provides an enormous amount of space in their Instagram captions. But it's worth noting that they recently started capping captions at three lines without users having to click "more" to see the whole thing, if they're viewing the post in their general feed. That being said, we don't recommend keeping your captions super short so users can see 100% of it without having to click "more." Instead, frontload your captions with the important content or text calls-to-action, and leave any hashtags, @mentions, or extraneous information for the end.
