Checked: October 17, 2026

TikTok's app takes up to 5 hashtags per post, a cap reported since mid-2025. TikTok's own advice is 2 to 3 relevant ones. Paste a caption below; every hashtag past the fifth is struck through.

## The short answer: Up to 5 hashtags per post. TikTok itself advises 2 to 3.

Since mid-2025, TikTok's app stops you at 5 hashtags with a "Maximum 5 hashtags" message. TikTok never announced the cap; Social Media Today reported it on August 17, 2025.

TikTok's Creator Academy goes further: "When it comes to hashtags, less is more, so we encourage you to use 2 to 3 relevant hashtags on each video." Hashtags are part of the caption, so they count toward its 4,000 characters, or 2,200 on a scheduled video.

- **Per post**: 5 (In the app since mid-2025)
- **TikTok's advice**: 2 to 3 (Relevant hashtags per video)
- **Caption**: 4,000 (2,200 on scheduled videos)

## Check a caption against TikTok's 5-hashtag cap

- Caption: up to 4,000 characters.
- Hashtags: up to 5 per post.

## Where the hashtag limit applies. TikTok has documented little of it.

| Place | Limit | Source |
|---|---|---|
| Caption in the app | 5 hashtags | Reported since Aug 2025; TikTok has not announced it |
| Scheduled video (API) | Not documented | TikTok's API reference only says caption hashtags are matched |
| Caption length | 4,000 characters (2,200 on API videos) | Hashtags count toward it |
| TikTok's advice | 2 to 3 per video | TikTok Creator Academy, Aug 2026 |

Checked on October 17, 2026. Schedule 5 or fewer so a post never depends on an undocumented API rule.

## How the hashtag rules changed. From no cap to five.

- **Aug 2025: A 5-hashtag cap** TikTok started to stop captions at 5 hashtags, rolled out from July 2025. TikTok gave no official explanation. (https://www.socialmediatoday.com/news/tiktok-implements-five-hashtag-limit-per-post/757857/)

## Pick your hashtags well. Fewer and relevant.

1. **Use 2 to 3** TikTok's own Creator Academy advises 2 to 3 relevant hashtags per video. The 5-hashtag cap is a ceiling, not a target.
2. **Pick what the video is about** TikTok says relevant hashtags help people find your video and connect you with audiences most interested in it.
3. **Write a clear caption** TikTok suggests clear descriptions so viewers understand the video quickly. Put the words people search in the caption.
4. **Skip filler tags** Tags like #fyp say nothing about the video. With 5 at most, give every slot to a topic tag.
5. **Schedule 5 or fewer** TikTok has not documented whether its API enforces the cap. Staying at 5 or fewer means no post depends on it.
6. **Keep a few sets ready** Save 2 or 3 small sets for your main topics so each video gets fitting tags without retyping.
