Instagram's hashtag limit is 5: what changed and what to do now

Instagram allows 5 hashtags per post, down from 30 in December 2025. What changed, what Instagram says hashtags do now, and how to pick your five.

What changed, and when

For years the limit was 30 hashtags per post. On 18 December 2025, Instagram's @creators account said that, starting that day, it would gradually limit the hashtags in a post or Reel caption to five. The reason it gave: a few hashtags that match the post work better than many generic ones. Instagram's help centre changed to match: it said 30 in November 2025, and says 5 now.

Meta's developer documents haven't caught up. The reference that scheduling tools build from still says a caption can carry 30 hashtags, and its error codes still describe a 30-hashtag limit. Go by the help centre, which matches the announcement.

Does the limit include comments?

Instagram's help centre says hashtags can go in the caption or a comment, and that a comment won't post if your photo or video has more than five. Meta doesn't say how caption and comment hashtags are counted together. The safe reading is that five covers the post and its comments, so moving extra hashtags into the first comment doesn't get round the limit. In practice Meta's API enforces neither yet: captions with up to 12 hashtags, and first comments with 7, posted through PostDaily in November 2026. Instagram doesn't say whether it counts the tags past five, so don't rely on them.

How long can a hashtag be?

Instagram publishes no length limit for a single hashtag; the only ceiling is the 2,200-character caption. Letters, numbers and emoji work. Spaces and special characters such as $ or % don't work.

Do hashtags still help?

Less than most people think, by Instagram's own account. In May 2024 Adam Mosseri said hashtags help people find your content but won't necessarily increase how many people see it. The December 2025 announcement added that generic tags such as #reels or #explore don't help a post appear in Explore and could hurt it. And back in 2021, Mosseri said that to show up in Instagram Search, keywords and hashtags belong in the caption, not the comments.

So treat hashtags as labels that help the right people search for you, not as a way to reach more of them.

How to choose your five

• Describe the post, not the platform. #sourdoughbaking says what the post is about; #reels and #instagood say nothing.
• Put them in the caption. That is where Instagram's search looks, and it keeps them visible when you review the post.
• Mix one broad tag with specific ones. A topic most of your audience searches for, then narrower tags for the place, the product or the event.
• Write keywords into the caption too. A sentence that names the subject helps search as much as a tag does.

Scheduling tools and the limit

Because Meta's API reference still says 30, a scheduler built from it may not stop you at five, and the API itself still publishes captions with more. PostDaily now counts the hashtags in the caption and first comments together and warns you when a post has more than five. The other limits it checks are on Instagram's limits, and how to schedule Instagram posts covers the rest.
