How Many Hashtags on Instagram in 2026? Five, and How to Pick Them

How many hashtags on Instagram? Five. Since December 2025, Instagram lets you add up to five hashtags to a post or reel, down from the 30 it allowed for years. If you’ve read advice telling you to use 20 or 30, it was written for rules that no longer exist, and a lot of it is still ranking on Google.

I read Instagram’s Help Center page and the studies people keep quoting, then checked the numbers against our database of 553,656 hashtags. Below is what the limit covers and how to choose your five.

How many hashtags on Instagram are allowed in 2026?

Five per post. Instagram’s Help Center page on hashtags now says it in two sentences:

“You can use up to 5 tags on a post. If you include more than 5 tags on a single photo/video, your comment won’t post.”

That’s from Use hashtags on Instagram, which I read on October 19, 2026. The same page says you can add hashtags “in the caption or comments of your post”, and that numbers are allowed but spaces and special characters like $ or % won’t work.

The change was announced on December 18, 2025. Social Media Today quoted Instagram’s announcement: “Instagram will gradually update the number of hashtags that you can include in a caption for a reel or post to five.” Note “gradually”: some accounts got the new limit later than others. Ten months on, the Help Center simply states five, so assume it applies to you.

What happens if you add a sixth hashtag?

For comments, Instagram is clear: a comment that takes you past five won’t post. For the caption itself, the Help Center doesn’t describe what the app does. Third-party reports talk about a pop-up or a caption box that stops accepting hashtags, but I couldn’t find Instagram documenting the exact behavior, so I won’t pretend to know it.

What I also couldn’t find: any sign that Instagram penalizes a post or an account for trying.

Do hashtags in the comments count toward the five?

Probably, yes. The Help Center talks about “5 tags on a post” and allows tags in the caption or the comments, then says the comment won’t post if you go over. The natural reading is one budget of five per post, shared between caption and comments. Instagram hasn’t said that in one plain sentence, though, so treat it as my reading, not a quote.

Either way, the old trick of a clean caption plus 30 hashtags in the first comment is dead.

Reels, carousels, Stories and your bio

The announcement covers “a caption for a reel or post”. A carousel is a post, so it gets five too. Here’s what’s documented and what isn’t:

Where	Hashtag limit	Source
Photo or video post	5	Help Center
Carousel	5 (it’s a post)	Dec 2025 announcement
Reel	5	Dec 2025 announcement
Comments	A comment that goes over 5 won’t post	Help Center
Stories	No official number	Not covered by the announcement
Bio	No official number	Not documented

The “10 hashtags in Stories” figure that blogs repeat isn’t in any Instagram documentation I could find. If you post mostly video, I go through tag choice reel by reel in how to pick hashtags for Reels.

Why Instagram cut the limit from 30 to 5

This didn’t come out of nowhere. The signs go back almost two years:

When	What happened
Until Dec 2025	Up to 30 hashtags per post, in the caption or comments
Feb 2024	Some users saw a pop-up that stopped them after five hashtags. Instagram told Social Media Today it was a “glitch”
Nov 2024	Instagram announced it was removing the option to follow hashtags
Feb and May 2025	Adam Mosseri, head of Instagram, said hashtags don’t increase reach
Late 2025	A test capped many users at three hashtags (screenshots reported in early December)
Dec 18, 2025	Instagram announced five per caption for reels and posts, rolling out gradually
Oct 2026	The Help Center says “up to 5 tags on a post”

Instagram’s own explanation, from the same announcement: “We find that using fewer (up to 5) more targeted hashtags, rather than many generic ones, can improve both your content’s performance and people’s experience on Instagram.” Press coverage of the announcement adds that Instagram also pointed to spam and to recommendations doing more of the work in discovery. TikTok had brought in its own five-hashtag limit earlier in 2025, so Instagram wasn’t alone.

You can see the problem the cap is aimed at in our data. On April 27, 2025, #viral had 988,579,798 posts. On October 19, 2026 it had 1,579,428,371. That averages out to about 1.09 million new posts a day, roughly 13 every second, over a stretch that includes ten months under the cap. People are still spending scarce slots on a tag that describes nothing.

How many hashtags should you use on Instagram?

Three to five, as long as each one fits the post. If you have five good ones, use all five. If you only have three, stop at three. A filler tag in slot five does nothing for you.

That’s my take, and it fits Instagram’s “fewer (up to 5) more targeted” line. The studies people quote are messier than their headlines:

Study	Sample	What it found	The catch
Later (June 2025)	18.1M feed posts	20 hashtags: highest average reach. 30: most likes and comments	Before the cap. Feed posts only, date range not given, correlation
Fanpage Karma (undated)	1.6M posts	5 hashtags: about 2% more reach than none. 1 to 3: slightly worse than none. More than 5: 3% less	No date range or method details. Run by a tools vendor. Tiny differences
Metricool (June 2026)	24,364,803 posts from 375,118 accounts, Jan–Feb 2025 and Jan–Feb 2026	Posts with at least one hashtag: 31.70% fewer views and 33.89% fewer interactions than the platform average	Compared with the average, not with similar posts that had no hashtags

Later’s numbers describe a world that ended in December 2025; you can’t act on “use 20” any more. Fanpage Karma and Metricool look like they contradict each other, but neither one isolates the hashtags. Both compare different kinds of posts from different kinds of accounts. Maybe the accounts that tag everything are smaller, or post more ads, or both. Neither study controls for that, so neither can tell you what adding a hashtag does to your own post.

What I’d take from them: a 2% difference is small enough to be noise, and nothing here says stuffing in more tags helps. (One more detail from Fanpage Karma’s sample: 45% of the posts it looked at used no hashtags at all.) For the longer version of that argument, I wrote up whether hashtags still work on Instagram with the Mosseri quotes and both studies in detail.

What is the 3-3-3 hashtag rule?

It’s a creator rule of thumb, not an Instagram rule. You pick three broad hashtags, three niche ones and three that are specific to the post: nine in total. It comes from the 30-hashtag era and still turns up in guides. I couldn’t find any data behind it, and Instagram has never recommended it.

It also doesn’t fit. Nine tags won’t go into a five-tag caption. Don’t confuse it with the three-hashtag cap Instagram tested in late 2025, either; that was a test, and the final limit is five.

The idea underneath it is sound, though: mix sizes instead of using five giants. Squeezed into five slots, it becomes something like this:

• One broad or mid-size tag for the topic (#sourdough, not #food)
• Two niche tags for what’s actually in the post
• One or two specific tags: your city, your community or your own branded tag

How to pick your 5 hashtags from a long list

If you’ve been posting for a while, your problem is probably the reverse of what it used to be: a saved list of 30 tags and room for five. Here’s how I’d cut it down.

1. Describe the post in plain words, the way someone would type it into search. “Scored sourdough loaf”, not “bread vibes”.
2. Collect 15 to 30 candidates from Instagram search, the hashtags on posts like yours, or a generator. I cover all the places to look in how to find hashtags for Instagram.
3. Cross out every tag that doesn’t describe this particular post. Most of a 30-tag list goes here.
4. Check the post counts of what’s left and sort them by size. If you’re not sure where to see a count or what it tells you, here’s how to check a hashtag’s popularity.
5. Make sure none of them is restricted and that each one is typed in ordinary letters.
6. Pick one topic tag (big or mid-size), two niche tags, and one or two specific ones.

Step four tends to surprise people. The hashtags you hear about are huge, but most hashtags aren’t. These are the size tiers our generator uses, with how the 553,656 hashtags in our database split across them (MetaHashtags data, October 2026):

Tier	Posts	Share of hashtags
Huge	100M+	0.06% (319 tags)
Big	10M–100M	0.9%
Mid	500K–10M	12.2%
Niche	10K–500K	44.0%
Tiny	Under 10K	42.6%
Zero	No posts	0.2%

The hashtags everybody knows, #love and #instagood and #viral, belong to a club of 319. Meanwhile about 87% (86.7%) sit in the niche and tiny tiers, under 500,000 posts. With five slots, most of yours should come from the middle of this table, not the top.

Example: five hashtags for a sourdough bakery

Say you run a small sourdough bakery and you’re posting a close-up of a freshly scored loaf. I ran #sourdough through our generator on October 19, 2026 and got dozens of related tags back. Here’s a slice of them with their live post counts, and what I’d do with each:

Hashtag	Posts	Keep or cut
#bread	21,125,413	Cut: true, but #sourdough says more
#sourdough	9,262,289	Keep: the topic
#sourdoughbread	3,745,946	Cut: too close to #sourdough to earn its own slot
#sourdoughstarter	1,281,078	Cut: not this post
#sourdoughclub	578,960	Keep: the community of people who bake it
#sourdoughscoring	232,998	Keep: exactly what the photo shows
#sourdoughbakery	116,784	Keep: what you are
#sourdoughsunday	14,851	Only if you post on a Sunday

That’s four. The fifth slot goes to a local tag: your town plus “bakery” or “sourdough”. I can’t give you a count for it because it depends on the town, but search it in Instagram first and make sure the recent posts come from real local accounts. My bet: for a bakery, that’s the tag most likely to reach someone who can actually buy the loaf.

Should hashtags go in the caption or the first comment?

The caption. Instagram’s Creators blog is direct about it: “To have your post found in Search, put these keywords and hashtags in the caption, not the comments.” It also says “Search results are matched by text, so make sure you’re including relevant keywords.” (What Creators Need To Know About Instagram Recommendations, August 2022.)

That second line matters more now that you only get five tags. Write the words people search for into the caption itself: “Fresh sourdough, scored this morning at our bakery in Leeds” does part of the job your old 25 extra hashtags were meant to do. I’ve put the rest of the placement rules, plus Stories and branded tags, in the main guide on how to use hashtags on Instagram.

Mistakes that waste your five slots

• Trimming an old 30-tag set from the top. Those sets were built for volume. Rebuild from the post instead, and cut down any sets saved in a scheduling tool too. Instagram hasn’t said how scheduled posts or edits to old 30-tag captions are handled under the new limit, so don’t find out on a post that matters.
• Engagement-bait giants. #reels has 1,431,016,941 posts and #explorepage has 792,571,500. In our snapshots they grew 39% and 33% between spring 2025 and October 2026. Of the seven giant tags we measured twice, only #viral grew faster. None of them describes anything about your post.
• Five versions of the same tag. #sourdough, #sourdoughbread, #sourdoughloaf and #sourdoughlove all say the same thing. Each slot should add something the others don’t.
• Lookalike characters. Copy a hashtag from a fancy-font generator and you can land on a different tag. In our database, #dogsofinstagram has 340,762,064 posts, while the same word typed with the “fi” ligature character is a separate hashtag with 976,940.
• Restricted tags. Instagram can make a hashtag unsearchable when the content under it keeps breaking its rules, and it reviews those tags over time. Our list of 1,861 hashtags Instagram has restricted includes everyday words like #desk, #pushups and #snowstorm. Check before you post, because the list changes without announcement.
• The same five on every post. If the posts differ, the tags should too.

Are Instagram hashtags still relevant in 2026?

Yes, for a narrower job than they used to have. Adam Mosseri said in May 2025 that hashtags “don’t improve visibility on Instagram” but are “a great way to let people know what a post is about and connect posts” (as reported by Social Media Today). Earlier that year he’d said they “don’t work” as a way to increase reach. And since late 2024 you can’t follow a hashtag at all, so nobody gets your post in their feed because they follow #sourdough.

What’s left is still useful. If your account is public, a tagged post shows up on that hashtag’s page (posts from private accounts don’t). Hashtags help your post appear in search, and they tell Instagram what the post is about. Five well-chosen tags can do all of that.

A five-hashtag checklist before you post

• Five at most, and fewer if you run out of good ones
• All of them in the caption, none in the comments
• Each one describes this post, not your account in general
• One topic tag, two niche tags, one or two specific ones (local, community or branded)
• No #viral, #explorepage or #reels
• Nothing restricted, and every tag typed in plain letters
• The main search words also appear in the caption sentence

Quick answers

What is the 5 hashtag rule?

It’s the Instagram hashtag limit: up to five hashtags per post or reel, announced on December 18, 2025 and rolled out gradually. Instagram’s advice with it was to use “fewer (up to 5) more targeted hashtags, rather than many generic ones.”

Can I still put 30 hashtags in the first comment?

No. Instagram’s Help Center says that if you include more than five tags on a post, your comment won’t post. Keep them in the caption, where they count for Search anyway.

Is it OK to use fewer than five hashtags?

Yes. Nothing from Instagram says you have to fill every slot, and Fanpage Karma’s per-count differences were a few percent at most. Three tags that fit beat five where two are filler.
