Facebook sets no hashtag limit and gives no number to aim for. A hashtag must be one word, and clicking it shows a feed of posts that use it. Paste a post below to count its hashtags.

## The short answer: There is no hashtag limit on Facebook.

Facebook's Help Center explains how hashtags work but sets no limit: write # with a topic or phrase as one word, numbers allowed, no punctuation or symbols such as $ and %. Clicking a hashtag opens a feed of posts that include it, and people can search for one.

Facebook gives no advice on how many to use. Hashtags are part of the post text, so they count toward its 63,206 characters, and reels published through Meta's API carry them in the description.

- **Per post**: No limit (Facebook publishes none)
- **Format**: One word (Numbers allowed, no symbols)
- **Counts toward**: 63,206 (The post's character limit)

## Count the hashtags in a Facebook post

- Caption: up to 63,206 characters.
- Hashtags: no fixed limit.

## Use hashtags with purpose. No limit is not a target.

1. **Pick a few specific ones** Facebook sets no number. A few clear topic tags read better than a long list, and they all count toward the post.
2. **Write them as one word** No spaces, no punctuation and no symbols such as $ or %. Numbers are fine.
3. **Use them to group a campaign** Clicking a hashtag shows every post that uses it, so one branded tag can collect a campaign in one feed.
4. **Check the audience** Who can see a hashtagged post follows the post's own audience setting.
5. **Put words first** Write the post for people, then add hashtags. Facebook gives no sign that more hashtags bring more reach.
6. **Keep sets ready** Save the few tags you use most so each post gets them without retyping.
