How Many Hashtags to Use on Instagram in 2026 (Now Capped at 5)

Use up to 5 hashtags per post, all of them specific to what the post is about. Instagram announced on December 18, 2025 that it would gradually limit captions on posts and Reels to five hashtags (down from 30), and said fewer, targeted hashtags work better than many generic ones (Social Media Today). Hashtags now work as topic labels that help Instagram categorize a post. They are not a reach trick, and your caption wording matters just as much.

Quick reference

• Feed posts and carousels: up to 5 relevant hashtags in the caption.
• Reels: up to 5 too, but 2-3 on-topic ones is plenty. Say the topic in the caption and on-screen text as well.
• Stories: 1-2 at most, or a location sticker. Instagram’s announcement covered post and Reel captions only.
• Skip: generic tags like #reels or #explore, follow-for-follow tags, and anything unrelated to the post.
• Measure: compare reach across your own posts instead of trusting a universal “best number.”

What Instagram has said about hashtags

The five-hashtag limit is the first thing to know, but the direction has been clear for a while:

• The cap. Instagram’s creators account said it would “gradually update the number of hashtags that you can include in a caption for a reel or post to five.” It had been testing a lower cap of three with some users before that. The rollout is gradual, so you may still see accounts using more. Source: Social Media Today, Dec 18, 2025, which links to the announcement on Threads.
• Reach. Adam Mosseri said in February 2025 that hashtags don’t work for increasing reach, and in May 2025 that they don’t improve visibility but are a good way to tell people what a post is about. Both statements are summarized in the same Social Media Today report.
• Why they still matter. Hashtags label your content for search and for people browsing a topic. They do not replace a clear caption, good content, or a strong opening.

If you see advice to use 20-30 hashtags, check its date. Later’s analysis of 18.1 million feed posts did find the highest average reach at 20 hashtags, but it covered feed posts only (no Reels or Stories), came from Later’s own scheduling data, and predates the five-hashtag cap (Later). It is no longer usable as practical guidance, because you can’t post 20.

What we could not confirm

Many articles quote per-band numbers, such as “3-5 hashtags get 2.3x more reach” or “10-15 hashtags add 5-10%.” We could not trace those to a named study or to Instagram, so we’ve left them out. Independent studies also disagree on the best count. Socialinsider’s analysis of over 75 million posts (March 2021 to March 2022) found hashtag count had little effect on distribution, with 3-4 hashtags showing the highest average engagement rate (Social Media Today). With a cap of five, the useful question is which five, not how many.

How hashtags work now

Instagram search reads captions, hashtags, alt text, and on-screen text. When someone searches “vegan recipes,” a post can match on any of these, so hashtags are one signal among several.

• Be specific. A post about sourdough should carry tags like #SourdoughRecipe, not #food.
• Put the topic in plain words too. Name the subject in the first line of the caption, and in the alt text and on-screen text for Reels.
• Don’t expect a spike. Mosseri’s comments above say hashtags don’t boost visibility, so judge them by whether they categorize the post correctly.
• Keywords carry the load. Prompting an AI tool for the phrases your audience actually searches helps. Our guide to using ChatGPT and Claude for Instagram includes a prompt that turns a post idea into search keywords you can reuse as hashtags.

A simple way to choose your 5

Use this structure, then adjust it to your niche.

1. 2-3 descriptive hashtags for exactly what’s in the post (#SourdoughRecipe, #SourdoughBaking).
2. 1-2 niche community hashtags for the group you want to reach (#SourdoughClub).
3. A branded hashtag only if you use it consistently. It gathers your own and your customers’ posts in one place. If you have few followers, a niche tag will usually do more for you than a brand tag with a dozen posts.

You don’t have to fill all five. If only three describe the post, use three.

How to find the right hashtags

Method 1: Instagram search

Search your core keyword and note the related hashtags Instagram suggests, with their post counts. As a rule of thumb, tags with tens or hundreds of thousands of posts are active without being buried, but treat that as a starting point and test it.

Method 2: Competitor and peer accounts

Look at accounts of a similar size in your niche and see which hashtags show up on their best-performing posts. Build your own list from what you see rather than copying their set.

Method 3: Check the hashtag page

Open the page and look at the top posts. If they all come from huge accounts, a smaller account is unlikely to appear there. If the page has almost no recent posts, there’s little audience.

Method 4: Your own data

Review your last 20 posts and note which hashtags appeared on the ones with the most reach. Keep those and drop the rest.

Try our free hashtag tools

Two free tools cover the research and checking steps:

• Instagram Hashtag Generator suggests relevant hashtags from your topic, so you start from a shortlist instead of a blank page.
• Hashtag Performance Checker helps you review which of your hashtags are worth keeping.

Use the generator to build a pool of 15-20 candidates, then narrow each post to its best five.

Hashtags to avoid

• Restricted hashtags. Instagram limits hashtags linked to spam or policy violations. If a hashtag page shows that recent posts are hidden, skip it.
• Overly generic hashtags. #love, #instagood and #photooftheday have enormous post volumes, so a single post gets lost. Instagram’s own announcement singled out generic tags like #reels and #explore.
• Unrelated hashtags. They mislabel the post and send it to the wrong audience.
• Follow-for-follow hashtags. #follow4follow and #like4like attract low-quality followers and can look spammy.

Rotating hashtags

Reusing the identical set on every post isn’t ideal, mainly because your topics change from post to post. Keep 3-4 sets of 5 for your main content themes, swap in one or two post-specific tags each time, and review the sets monthly against your own reach numbers. Instagram has not published a rule that penalizes repeating hashtags, so don’t rotate for its own sake.

Measure what works

Instagram Insights shows where a post’s views came from. Look at how many came from hashtags or search and compare that across posts that used different sets. If a post gets almost nothing from hashtags, the tags may be too competitive, too obscure, or off-topic. We don’t have a verified benchmark for a “good” percentage, so compare against your own past posts rather than an industry figure.

Your 2026 hashtag workflow

1. Research 15-20 niche hashtags with Instagram search, peer accounts, and the generator above.
2. Group them into 3-4 sets of up to 5, by content theme.
3. Use each set on a few posts, then compare reach.
4. Keep the sets that perform, replace the weakest, and put the topic in the caption in plain words every time.

Hashtags still help label your content, but they won’t carry a post by themselves. Pick a few accurate ones, write a caption that names the topic, and check the results against your own account.
