Frequently asked questions
How many hashtags can I use on Instagram?
Since December 2025, Instagram allows up to 5 hashtags per post and Reel. The counter warns you if you use more.

X counts every link as 23 characters, and some platforms count certain emojis as two. Leave a small margin when you are close to a limit.
