Frequently Asked Questions

How should I format Instagram captions?

An Instagram caption is generally one sentence long but can be longer depending on the purpose of the post and the subject matter. At the end of the caption, emoji and up to four hashtags are often included.

How long can an Instagram caption be?

An Instagram caption can be up to 2,200 characters, but the best practice is to write a caption that’s shorter. Captions cut off in users’ feeds after three or four lines. There’s no need to keep it to exactly that length, but just be sure to front-load your captions with the important content or calls to action.

Should I include hashtags in the caption?

Hashtags are not necessary but can be a great way to connect your post to a larger conversation with other users. They can also add some fun to your caption. If you do use hashtags, use them sparingly and at the end of your caption. Limit them to three or four at the most to avoid your post coming across as spam.

Should I include an emoji in the caption?

Emoji can add personality to your caption and enhance the story you’re telling in your post. Just be mindful not to add too many, as they can become distracting.
