Instagram hashtags in 2026: how many to use
Last updated · By the HowSociable editorial team
The honest short answer: hashtags no longer boost reach on Instagram the way they used to. Head of Instagram Adam Mosseri says hashtags do not improve visibility, and Instagram moved from a cap of 30 to up to 5 per post. Use 3 to 5 highly relevant tags as topic labels, then put your real effort into keyword-rich captions, which now drive more discovery. Skip the copy-paste block of 30.
Do Instagram hashtags still work?
Not as a reach lever. In 2025, Adam Mosseri stated plainly that hashtags do not improve visibility on Instagram, while noting they are still a good way to signal what a post is about. Instagram also removed the ability to follow a hashtag in late 2024. Discovery has shifted toward keyword search: Instagram matches what people type against usernames, bios, captions and locations, so a well-written caption can surface your post even without a matching tag.
How many hashtags should you use?
Far fewer than the old “fill all 30” advice. Instagram moved to a limit of up to 5 hashtags per post and Reel (rolling out through late 2025 into 2026), and said using fewer, more targeted hashtags can improve performance. So aim for 3 to 5 highly relevant tags. Ignore any guide quoting a precise engagement-lift percentage for a specific number, those figures are not traceable to a real Instagram study.
There is no “best” hashtag list, only the right mix
Any static top-100 block goes stale and wastes your five slots. Build a small, deliberate mix instead:
| Use | Example | Why |
|---|---|---|
| One broad category tag | #skincare | Tells the algorithm the general topic. Big tags alone bury you, so use only one. |
| Two or three niche tags | #sensitiveskintips, #skincareforacne | Specific enough that your post can actually surface for the right, smaller audience. |
| One branded or community tag | #yourbrandname | Builds a searchable home for your content and any community around it. |
How to find the right hashtags for your account
- Treat each of your 5 slots as a keyword that precisely describes this post, not a generic reach grab.
- Use Instagram’s search bar: type a seed keyword, open the Tags tab, and read each tag’s post count to judge how competitive it is. Note the related tags it suggests.
- Mix sizes: one broad tag, two or three mid-size niche tags, one specific or branded tag. Relevance beats popularity.
- Study three to five accounts your size in your niche and see which tags appear on their best posts.
- Reinforce your tags with the same keywords in your caption, bio and alt text, since keyword search now drives more discovery.
- Check Instagram Insights to see which tags actually delivered reach, keep the winners, and refresh the set instead of reusing one static block.

Frequently Asked Questions
Barely, as a reach tool. Head of Instagram Adam Mosseri has said hashtags do not improve visibility on Instagram, and Instagram removed the ability to follow hashtags in late 2024. They are still useful for telling the algorithm and search what a post is about, and a post can appear when someone searches that specific tag. But discovery has shifted toward keyword search, so keyword-rich captions, bios and on-screen text now do more for reach than a block of hashtags.
Fewer than the old advice suggested. Instagram moved from its long-standing cap of 30 hashtags to a limit of up to 5 per post and Reel, rolling out through late 2025 and into 2026, and it says using fewer, more targeted hashtags can improve performance. So the practical answer is roughly 3 to 5 highly relevant tags. Be wary of blog posts quoting exact engagement-lift percentages for a specific number: those figures are not traceable to a primary Instagram study.
There is no universal best list, and any static top-100 block goes stale fast. The best hashtags are the ones specific to your niche and to that individual post: a mix of one broad category tag, two or three niche tags, and one branded tag. Because Instagram now caps you at around 5, each one should earn its place as a precise keyword for what the post is about, not a generic reach grab. Research them for your account rather than copying someone else's set.
Only indirectly, and less than they once did. Hashtags can help the right person find a relevant post through search, which can lead to a follow, but they do not multiply your reach. Reels, watch time, sends (DM shares) and keyword-optimized captions are the real levers for reaching new people. See our guide on how to get more followers on Instagram for what actually moves the needle.
No, you can still add hashtags to posts and search by hashtag to find related content. What Instagram removed, in late 2024, was the ability to follow a hashtag as if it were an account. Combined with the shift to keyword search and the new lower limit, the practical effect is that hashtags matter less than they used to, but they have not disappeared.
