How many hashtags on Instagram? Up to 5 per post

How many hashtags can you use on Instagram? Up to 5 on a post or Reel, as of October 2026. Plenty of guides still show a higher number, so this page sticks to what Instagram itself says: the limit, what hashtags do, where to put them and what Instagram doesn't say. Then it gives you a simple way to pick 3 to 5 for each post. Every Instagram rule below comes from Instagram's own pages, checked on 25 October 2026.

The Instagram hashtag limit: 5 per post

Three official pages mention the limit, and they don't all say the same thing:

Here's what that means for you:

• Reels and photo posts: the 5 applies to both. Instagram's announcement names a Reel or post, and its Help Center says a post.
• Carousels and Stories: neither page mentions them separately, so don't plan on more than 5 there either.
• Caption plus comments: the Help Center says 5 on a post and doesn't split it into caption and comments. Plan on 5 in total.
• The old number: you'll still see 30 in older guides and on Meta's developer page for apps. When the pages disagree, go by the Help Center.
• Going over: the Help Center only says a comment with more than 5 won't post. It doesn't say what happens to a caption, so don't test it on a post you care about.

What hashtags do on Instagram

Instagram documents a few things, and it's worth knowing which are which:

• They put a post on a hashtag page. If you have a public account and add a hashtag to a post, the post is visible on that hashtag's page, which shows the photos and videos people have uploaded with it. Posts from private profiles don't show up publicly there.
• Where you land in the results. Instagram says the order of posts in hashtag search results may depend on when a post was shared, how others engage with it and whether it meets its Recommendation Guidelines. It may remove posts from the results if a hashtag is used for content that breaks its Community Standards.
• Some hashtags can't be searched. Instagram says a hashtag may not be searchable if its text or the content under it keeps breaking its Terms of Use or Community Standards.
• They have format rules. Numbers are fine. Spaces and special characters like $ or % won't work. You can only add hashtags to your own posts.

Do hashtags still work on Instagram? In the sense that matters most to Instagram, yes: a public post with a hashtag shows on that hashtag's page. None of the pages we checked says how much reach that adds. What Instagram does say, in its December 2025 guidance, is that a few targeted hashtags beat many generic ones. So treat hashtags as labels that describe a post, not as a lever for reach.

What Instagram says about choosing them

Instagram's Creators account gave two tips with the 5-hashtag announcement:

• Be intentional. Focus on hashtags that are relevant to what you're publishing. Its example: a beauty creator uses beauty-related hashtags, to help people who are interested in beauty content find them.
• Don't spam your caption. Too many irrelevant or generic hashtags, like #reels or #explore, don't actually help a post appear in places like Explore, and could hurt its performance. Instagram says using fewer, more targeted hashtags can improve both performance and people's experience.

Where to put hashtags: caption or comments

Instagram's Help Center says you can add hashtags in the caption or in the comments of your post. To add one to a post you've already shared, edit the caption or add it in a comment.

It doesn't say that one spot works better than the other, so advice about a "best place" isn't coming from Instagram. We suggest the last line of the caption:

• It's one place to check, so you can count to 5 at a glance.
• Your first lines stay free for the people reading.
• You can edit the caption later if you want to swap a hashtag.

Unisenda puts your hashtags in the caption, and it can't schedule a first comment on Instagram yet (it can on LinkedIn and Bluesky). If you'd rather have them in a comment, add it in Instagram after the post goes out.

How to choose 3 to 5 hashtags for a post

Instagram gives a ceiling ("up to 5") and a direction ("fewer, more targeted"), not a number to aim for. This routine follows that advice. It's ours, not Instagram's.

1. Write the caption first, then sum up the post in one sentence. Say you run a small ceramics shop and you're posting a handmade green mug: "A handmade mug with a green glaze."
2. List 8 to 10 hashtags that describe that sentence: the object (#ceramicmug), the craft (#handmadepottery) and the detail (#greenglaze). Add a place or community only if it's true for the post.
3. Search each one in Instagram. Skip any you can't find, since some hashtags aren't searchable, and any whose page is full of posts that have nothing to do with yours.
4. Cut the list to 3 to 5. Drop generic ones like #reels or #explore, and when two hashtags say the same thing, keep the more specific one.
5. Put them on the last line of the caption. Next time, swap one or two so each post's hashtags describe that post, instead of pasting the same block every time.
6. Look at how the posts do in Instagram's insights over a few weeks before you decide a set works. Our guide to the best time to post on Instagram shows where to find them and how to run a fair test.

Different hashtags on each network

A hashtag block that suits Instagram looks odd elsewhere, and other networks set their own rules. As of October 2026:

For Facebook, TikTok, LinkedIn, Pinterest and Bluesky, see our table of social media character limits, which says where we couldn't find an official hashtag limit. Hashtags count toward a caption's character limit, and our free caption length checker shows how many hashtags your Instagram caption has next to the limit of 5. The free hashtag counter checks them against every network's limit and spots repeats.

How to give Instagram its own hashtags in Unisenda

Unisenda is the scheduler we make. Every account you select gets its own tab with its own caption, so Instagram can have 5 hashtags while X gets 1 and LinkedIn gets none.

1. Click Create post and select your Instagram account and the other accounts that should get the post.
2. Write the shared caption under All networks, without hashtags.
3. Open the Instagram tab and give Instagram its own caption: your text, then 3 to 5 hashtags on the last line. A counter shows how much of Instagram's 2,200 characters you've used.
4. Open another network's tab, such as X, to give it a shorter caption with one or two hashtags, or none.
5. Check the previews. Unisenda flags more than 5 hashtags on Instagram before you schedule, so a sixth won't slip through.
6. Click Schedule for, pick the date and time, and click Schedule.

If you reuse the same ending, save it in a Preset. Presets remember your usual accounts, caption, image shape and time of day.

Unisenda has no hashtag suggestions, so you choose the hashtags yourself. For the full walkthrough, see how to schedule Instagram posts, and for Reels, the Reels size and length guide.
