How many hashtags can you use on Instagram? Five, and how to pick them

October 3, 2026

How many hashtags can you use on Instagram? Five per post. As of October 2026, Instagram’s own help centre says you can use up to five tags on a post, and that a comment carrying more than five will not post at all. The old habit of pasting a block of twenty or thirty tags under every photo is over. That changes the question people actually need answered: if you only get five, which five? This guide covers the rule as Instagram states it, what happens when you go over, where the tags can sit, and a simple way to choose five that each reach somebody.

How many hashtags can I use on Instagram in 2026?

Five. Here is the line from Instagram’s help article on using hashtags, as read in October 2026:

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.

Instagram’s @creators account announced the change on Threads in December 2025:

New hashtag guidance: Starting today, Instagram will allow up to 5 hashtags in a reel or post.

So the same number applies to a feed post and to a Reel. If you learned Instagram when the ceiling was thirty, every saved hashtag set, caption template and scheduling preset you built back then is now too long.

What happens if you add more than five

The help centre is specific about one case: a comment with more than five tags will not post. You find out because it fails, which is the good outcome. The worse outcome is the one nobody notices: a scheduling tool or a saved caption that still carries an old thirty-tag block, posting from somewhere you are not watching.

Before your next post, open every saved set you reuse and cut it to five. That includes:

• caption templates in your notes app;
• hashtag groups saved inside a scheduler;
• a “first comment” preset that drops tags under each post;
• anything a teammate or freelancer posts for you from their own copy.

If a post has gone out with tags missing or a comment that never appeared, edit the caption down to five and add them there.

Where the five can go: caption or comment

Instagram lets you put hashtags in the caption or in a comment on your own post. If you have a public account, a tagged post becomes visible on that tag’s page. You can also add tags to a post you have already shared by editing the caption or commenting on it.

Two smaller rules from the same help article still trip people up:

• Spaces and special characters break a tag. Numbers are fine, so #bakery2026 works, but #$5coffee or #coffee shop will not do what you meant.
• You can only tag your own posts. A tag in a comment on somebody else’s photo does not file their photo under it.

The help centre states the limit per post, so the safe reading is one budget of five across the caption and your comments together. Put them in the caption, where you can see them at a glance, and you will never wonder which count applies.

How to choose your five hashtags

With thirty slots, a weak tag cost nothing. With five, every slot is a fifth of your reach through tags, so each one has to point at a group of people who would actually stop on this post. A pattern that works for most accounts is one tag per job:

Treat it as a starting pattern. A travel account might spend two slots on place. A product brand might drop the place slot for a second product tag. What matters is that no two tags do the same job.

To fill each slot:

1. Write one sentence about who should see this post. “People in Leeds who bake bread at the weekend” is a target. “Everyone” is not.
2. List ten to fifteen candidate tags in the words that person would type, including place names and the slang your community uses.
3. Search each one on Instagram and open its page. Look at the recent posts. Are they the kind of thing you post, from the kind of account you want to reach? Drop any tag that means something else, or is full of giveaways and reposts.
4. Judge how busy each tag is. A tag with almost nothing recent has no audience yet. A tag flooded every minute buries your post before anyone sees it. Keep the ones with steady recent activity you could stand out in.
5. Pick five that each do a different job, using the table above, and put them in the caption.
6. Keep the rest as a pool. Rotate tags in and out across posts, so you learn which ones bring visits.

If you need help with step 3, how to search hashtags on Instagram covers searching one tag or several on the phone and the web. For a tag that might be restricted, banned hashtags on Instagram shows how to check before you use it.

What to do with your old thirty-tag sets

Do not throw them away. An old set is a list of candidates you already researched once, and it is the fastest way to build the pool from step 6.

1. Paste the old set into a note.
2. Delete anything generic that every account in the world uses, such as #instagood or #photooftheday. They waste a slot.
3. Delete duplicates that do the same job, keeping the most specific one.
4. Sort what is left into the five jobs in the table.
5. Re-check the survivors on Instagram, because a tag that was lively a year ago may be dead or overrun now.

You will usually end up with a pool of fifteen or twenty that you can rotate through for months. The general method of building a pool, with broad, mid-size and niche tags and a worked example, is in best hashtags for Instagram. For Reels specifically, best hashtags for Instagram Reels explains why the tags should describe what happens in the video.

Do five hashtags still matter?

Yes, as one signal among several. A hashtag still files your post on that tag’s page and tells Instagram what the post is about, and Instagram announced a smaller limit for them, which is a reason to aim each one carefully. Your caption, the content itself and how people respond to it matter too. If you want to test whether tags are doing anything for your account, do hashtags still work on Instagram? shows how to check with your own posts.

When choosing five by hand is enough

For most accounts, the routine above is all you need. It takes an hour the first time and a few minutes per post after that. Stay with it if:

• you post a few times a week in one niche;
• your audience is local and you know the place names;
• you already have an old set to cut down;
• you are happy to re-check your pool once a month.

A faster way to research the pool

The slow part is steps 2 to 4: deciding which tags to look at, how far back to read, and what to compare across them. That gets heavy when you manage several niches, several clients, or a campaign where the wrong five tags cost real money.

Hashtag Ninja takes that research question as a sentence. You write something like “which sourdough and baking tags in Leeds carry real local bakers rather than reposts”, and the free planner returns a research plan: the tags to look at, how many posts per tag, over what window, and the assumptions it made. It needs no account.

To be clear about where it stands: running the plan, meaning collecting the posts and returning a written report and a CSV, is open, on the 500 free rows a signed-in account gets every 30 days. The pricing page says what that will cost and what state it is in. The plan on its own still replaces the first step of the routine, since it is the candidate list and checklist you would otherwise write by hand.

Quick answers

How many hashtags can you use on Instagram? Up to five per post, and the same for Reels, as of October 2026.

What happens if I use more than five? Instagram’s help centre says a comment with more than five tags will not post. Cut your saved sets to five so nothing fails quietly.

Should I use all five? Use as many as you have good tags for. Four well-aimed tags beat five where one is filler.

Can I put hashtags in a comment instead of the caption? Yes, Instagram allows either. The limit is stated per post, so keep the total at five.

What did Instagram allow before? For years the ceiling was thirty tags per post. If your templates still carry blocks that long, they date from that rule.
