Instagram Hashtags: How Many to Use and How to Pick Them

If your hashtag habit dates from the days of 30 per post, it needs an update. Instagram now caps a post at 5 hashtags, and that changes how you pick them. With five slots, every generic tag takes the place of one that describes your post.

This guide gives the current limit and Instagram's own advice, a four-step method for brand posts, example sets for six niches, and the mistakes to drop. Hashtags are one small part of running a business account; the Instagram for business guide covers the rest.

How many hashtags to use on Instagram

Five at most. On December 18, 2025, Instagram's @creators account announced on Threads: "Starting today, Instagram will allow up to 5 hashtags in a reel or post." The same post said the new number would reach accounts gradually.

The Instagram Help Center (checked November 2026) now reads: "You can use up to 5 tags on a post." An archived copy of the same page from December 2020 said 30.

The Help Center also says that if you include more than 5 hashtags on a photo or video, "your comment won't post." Neither the Help Center nor the @creators announcement says whether hashtags in the caption and in the comments count toward the same five.

What Instagram recommends

Five is a ceiling, not a target. In the same Threads post, @creators recommends using fewer, more targeted hashtags (up to 5) rather than many generic ones, and says this can improve how content performs and how people experience it.

A tips card in that post adds two rules. Be intentional, and use hashtags that are relevant to the content. Don't fill your caption with irrelevant or generic tags such as #reels or #explore: according to Instagram, those don't help a post appear in Explore and can hurt its performance.

What hashtags do on Instagram today

A hashtag files your post under a topic. When a public account adds one, the post appears on that hashtag's page or in its search results, according to the Help Center. Posts from private accounts don't appear publicly on hashtag pages.

Inside those results, Instagram orders posts by when they were published, how people interact with them, and whether they follow the Recommendation Guidelines.

What hashtags don't do is raise your reach. In a reel from May 31, 2024, Adam Mosseri said hashtags help people interested in a topic find your content, but "won't necessarily increase your content's visibility." The Verge reported in December 2025 that Mosseri said hashtags help with search but "don't increase your reach."

One feature is gone. Instagram told Social Media Today in November 2024 that it was removing the option to follow hashtags. You can still add hashtags to posts and search for them.

Hashtags, keywords and Instagram search

Meta's system card for Instagram search (Meta Transparency Center, updated June 23, 2026) lists a ranking signal for hashtags: how closely the words in a search match the hashtag. For accounts, it lists how closely they match the username or the profile name, which is why your profile name deserves a keyword too.

For the caption, the official advice is older but plain. Instagram's 2021 post on how search works and the 2023 @creators reach tips both recommend relevant keywords in the caption. Write the caption in the words a customer would search, then let the hashtags label it.

How to choose hashtags for a brand post

The method has four steps. Run them for every post, not once for the whole account.

1. Name the subject of the post. Describe this post in two or three words, the way a customer would: "sourdough bread," "curly haircut," "first-time homebuyer." Turn that into one or two hashtags. A post about a new sourdough loaf gets #sourdough, not #food.
2. Check the words your audience uses. Search each candidate on Instagram and open the hashtag results. Keep the tag if the top posts look like yours and come from the people you want to reach. Drop it if they belong to another industry or another language.
3. Add your niche or your place. A local business adds its city or neighborhood, such as #austincoffee or #phoenixrealestate. An online business adds its audience or niche instead, such as #fitover40.
4. Add a brand hashtag, if you use one. A hashtag with your brand or campaign name gathers your posts, and posts from customers with public accounts who use it, on one hashtag page. It earns its slot only if you use it every time and ask customers to use it too.

Then stop at five, or sooner. Reread the set and ask of each tag: would someone looking for this exact post search for it? If not, cut it.

Best hashtags for Instagram by niche: 6 example sets

The best hashtags for Instagram are the ones that describe the post in front of you, so no single list works for every account. The sets below apply the four steps to six fictional businesses. They illustrate the method and promise no reach; search each tag before you borrow it.

Business (fictional)	Post	Hashtag set
Bakery in Chicago	A new sourdough loaf	#sourdough #sourdoughbread #chicagobakery #chicagoeats #hearthandcrumb
Curly hair salon in Atlanta	Before and after of a curly cut	#curlyhair #curlyhaircut #naturalhair #atlantasalon
Online personal trainer	A 20-minute home workout	#homeworkout #strengthtraining #beginnerworkout #fitover40
Real estate agent in Phoenix	Costs first-time buyers forget	#firsttimehomebuyer #homebuyingtips #phoenixrealestate #arizonahomes
Bookkeeper for small businesses	Reminder about quarterly estimated taxes	#smallbusinesstax #bookkeeping #estimatedtaxes #smallbusinessowner
Clothing boutique in Nashville	The fall denim drop	#womensdenim #falloutfits #nashvilleboutique #nashvillestyle #wearwrenandco

Two sets use all five slots, and both spend the fifth on a brand hashtag (#hearthandcrumb and #wearwrenandco). The other four sets stop at four, because a fifth tag would have been filler.

Where to put hashtags: caption or comments

Both places work. The Help Center says you can add hashtags in the caption or in the comments, and on a post that's already live, you can edit the caption or add them in a comment.

For search, Instagram's 2021 post on how search works is specific: "put keywords and hashtags in the caption, not the comments." The 2025 @creators announcement also describes the limit as hashtags "in a caption." Write the caption first and add the hashtags at the end. If you need a structure for the caption itself, start with these Instagram caption formulas.

Common hashtag mistakes

• Tags that don't match the post. A hashtag for a topic the post doesn't cover files it under the wrong subject. Step 1 prevents that.
• The same set on every post. A block pasted from your notes app describes your account, not this post.
• The old wall of 30. If your phone still holds the 30 tags you used to paste into the first comment, delete the note. That block is six times the current limit.
• A hashtag that no longer shows in search. According to the Help Center, a hashtag can stop being searchable when the posts or text tied to it consistently break Instagram's Terms of Use or Community Standards. Instagram reviews those hashtags periodically and can make them searchable again. The Help Center explains the rule without publishing a list, so step 2 is your check: if a tag doesn't come up in search, pick another.

Where Zynta Flow fits

Zynta Flow writes the caption for each post with AI, for 10 credits, in the tone of voice and language style saved in your brand kit. Hashtags come back in their own field, separate from the caption text, and Zynta Flow keeps at most 5 for Instagram. You can also generate a caption with no hashtags at all. Either way, run the final set through the four steps before you schedule the post. See how the AI captions follow your brand voice.

Frequently asked questions

How many hashtags can you use on Instagram?

Up to 5 per post or reel. Instagram's @creators account announced the limit on December 18, 2025, and the Instagram Help Center now says the same. Before that, the limit was 30.

What are the best hashtags for Instagram?

The ones that describe the post: its subject, the words your audience searches, and your niche or city. Instagram recommends a few targeted hashtags over many generic ones such as #reels or #explore. A ranked list of popular tags can't know what your post is about.

Do hashtags increase reach on Instagram?

No, according to Adam Mosseri. In a 2024 reel he said hashtags won't necessarily increase your content's visibility, and The Verge reported in 2025 that he said they don't increase reach. Hashtags help people who search or browse a topic find your post.

Should Instagram hashtags go in the caption or the first comment?

Both work, according to the Instagram Help Center. For search, Instagram's 2021 guidance says to put keywords and hashtags in the caption, not the comments.

What happens if you add more than 5 hashtags?

The Instagram Help Center says that with more than 5 hashtags on a photo or video, your comment won't post. Neither the Help Center nor Instagram's December 2025 announcement says how hashtags in the caption and in the comments add up, so keep the total at five or fewer.

Can you still follow hashtags on Instagram?

No. Instagram told Social Media Today in November 2024 that it was removing the option to follow hashtags. You can still add hashtags to your posts and search for them.

Why doesn't my post show up on a hashtag page?

Posts from private accounts don't appear publicly on hashtag pages. A hashtag can also stop being searchable when the content tied to it keeps breaking Instagram's rules. Within the results, Instagram orders posts by when they went up, how people interact with them, and whether they follow its Recommendation Guidelines.
