What is the Instagram caption limit?

The Instagram caption limit is 2200 characters (roughly 300–500 words), but only the first 80–100 characters are visible in the main feed, which is about 15 words on average. Therefore, the most important information should be in the first 10–15 words. 

Writing concise captions can be time consuming, but with QuillBot’s free AI Instagram caption generator, it only takes a few seconds.

What is a hashtag?

A hashtag is a tag used on social media to identify and organize content. The tag is preceded by the hash symbol (#), which is why it’s called a hashtag.

A few examples are: #summervibes, #WorldCup2026, and #bookclubsofinstagram.

You can come up with hashtags on your own, or you can use a hashtag generator. QuillBot’s AI hashtag generator will create hashtags for you in a matter of minutes.
