How Many Hashtags to Use on Instagram for Growth

Okay, let’s be honest for a second. You’ve probably fallen down the hashtag rabbit hole — one blog swears by exactly three, another insists you cram in all thirty, and some confident stranger on Reels tells you hashtags are “dead” entirely. No wonder your head is spinning. You just want to know the number, drop it in, and get back to actually making content.

So let me give you the real answer, the one you can actually use.

There is no single magic number for how many hashtags to use on Instagram for growth — the right count is the one that consistently pulls the most reach and engagement for your specific account. Instagram lets you add up to thirty hashtags per post, and the genuinely reliable move is to test a few different quantities against your own reach data, watch which range performs best for your niche, and let your numbers make the call. I promise this is more freeing than memorizing someone else’s rule, and I’m going to walk you through the whole method.

Grab a cup of something warm, because we’re going to walk through this together — how many hashtags actually make sense, how to build a set that gets discovered, how to test your own best number, and the quiet mistakes that waste your hashtags without you noticing. By the end, you’ll stop Googling this question forever, because you’ll have your own answer.

So how many hashtags should you use on Instagram for growth?

Here’s the thing I wish someone had told me before I wasted months copying other people’s hashtag counts: Instagram has never officially crowned a perfect number, and the platform’s own guidance has shifted over the years. At various points Instagram’s own team has suggested a smaller, well-chosen handful; at other points creators have sworn by filling all thirty slots. Both camps have real accounts that grew. That’s your first clue — the number itself is less important than what those hashtags are doing.

Think of hashtags as little doorways. Each relevant one opens a path for a stranger who’s browsing or following that topic to stumble onto your post. More doorways can mean more chances to be found — but only if each doorway leads somewhere your ideal person actually wants to go. Thirty doorways that open onto crowded, generic hallways full of millions of posts won’t help you nearly as much as eight doorways that open right into the cozy room where your exact audience is already hanging out.

So the honest framing isn’t “how many hashtags to use on Instagram for growth,” it’s “how many relevant, well-chosen hashtags help my content get discovered by people who’ll actually care.” For some accounts that sweet spot lands lower; for others it’s higher. The only way to know yours is to test — and I’ll show you exactly how in a few minutes. First, let’s make sure the hashtags you’re choosing are worth counting at all.

Why does relevance matter more than the number of hashtags?

Let me say this plainly, because it’s the single most important thing in this whole article: a smaller set of genuinely relevant hashtags will almost always beat a larger pile of random popular ones. If you remember nothing else, remember that.

Here’s why. When you tag your post, Instagram uses those tags as one of many signals to understand what your content is about and who might enjoy it. If your hashtags are laser-matched to your actual content, you’re helping the algorithm hand your post to the right people. But if you stuff in giant generic tags just because they’re popular, you’re basically shouting into an ocean where your post gets buried under millions of others within seconds — and worse, you might attract a flood of mismatched viewers who scroll right past, which tells Instagram your content isn’t resonating. That early signal can quietly hurt you.

Picture two versions of the same post from a small pottery studio. Version one uses thirty of the most crowded tags imaginable — the kind with hundreds of millions of posts, chased by every account on earth. Version two uses twelve tags that speak directly to handmade ceramics, wheel-throwing, and the studio’s local craft community. Version two wins nearly every time, because those tags reach people who genuinely light up at pottery, not a random firehose of strangers. See the difference? It was never about the number. It was about the fit.

This is exactly why I want you to stop obsessing over the count and start obsessing over relevance first. Once your hashtags are tightly matched to your content and your people, then the question of how many becomes a fun little experiment instead of an anxious guess.

What kinds of hashtags should make up your set?

Before we count anything, let’s build a good set. The healthiest hashtag strategy isn’t one flavor of tag — it’s a little layered mix, like a well-balanced playlist. Here are the layers I’d reach for.

Niche and specific hashtags

These are the smaller, tightly-focused tags that describe exactly what you do — think the specific craft, style, or sub-topic rather than the broad category. They usually have fewer total posts, which sounds like a downside but is actually a gift: less competition means your post has a real chance to stick near the top and get seen by people deeply interested in that exact thing. These should be the backbone of your set.

Mid-size hashtags

These sit in the middle — popular enough to have steady activity, but not so gigantic that your post vanishes in a blink. They widen your reach a little beyond the super-niche while still keeping your audience relevant. A handful of these balance your set beautifully.

Community and branded hashtags

These are the tags a specific community, challenge, or movement rallies around — plus any branded hashtag you create for your own account. Community tags connect you to people who are actively participating, not just passively scrolling, which often means warmer, more engaged eyes. And your own branded tag helps loyal followers find your content and tag you back over time.

A few broader hashtags — used sparingly

There’s a place for one or two larger tags to cast a slightly wider net, but treat them as seasoning, not the main dish. Leaning too hard on the biggest tags is where most people go wrong, because those are the crowded hallways we talked about. Sprinkle, don’t pour.

When you blend these layers, you get a set that reaches genuinely interested people at several levels of specificity. That mix tends to outperform any single-flavor approach — and it gives your testing something worthwhile to measure. If you want to go deeper on which discovery signals actually move the needle for growth, this guide on how to grow on Instagram ties hashtags into the bigger picture of content, consistency, and community working together as one system.

How do you find hashtags your audience actually follows?

Building that layered set is easier than it sounds once you know where to look. You don’t need a fancy tool to start — Instagram itself is a wonderful research partner if you use it thoughtfully.

Start by opening the search bar and typing a word that describes your content. Instagram will suggest related hashtags and show you roughly how many posts each one has. That post count is your rough gauge of crowdedness — very high means competitive, moderate means more approachable. Jot down a mix across the sizes we just talked about.

Next, do a little friendly spying — the healthy kind. Look at a few accounts similar to yours that are a bit further along, plus the accounts of people who are your ideal audience. What tags show up on their posts? Which ones appear again and again in your corner of Instagram? Those repeat offenders are usually the community’s real gathering spots, and they’re gold for you.

Then tap into a promising hashtag and actually look at the posts under it. Are they the kind of content your people would love? Is the vibe a match? A tag can look perfect on paper and still be full of spam or totally off-tone — your own eyes are the final check. Build yourself a running list of tags you trust, sorted loosely by size, and you’ll have a well of options to draw from every time you post. Save these in a note so you’re never scrambling at the last second.

How do you test your own best hashtag number (without a spreadsheet meltdown)?

This is the part I actually love, because it turns “how many hashtags to use on Instagram for growth” from an anxious guess into something you can measure and trust. Here’s a doable method you can start this week — no data-science degree required.

Step one: pick two or three hashtag counts to compete

Choose a few distinct quantities to test — for example, a small set, a medium set, and a fuller set. You want them different enough that any performance gap is meaningful. Give them names in your notes if it helps; I’m not above calling one “the lean set” and one “the loaded set.”

Step two: keep everything else as fair as possible

To test the number honestly, the number should be the main thing changing. So keep the content type and quality similar across your test — don’t put your most stunning reel with your small set and a plain graphic with your fuller set, or you’re testing the content, not the hashtag count. Rotate similar-caliber posts through each count so the comparison is fair. Always keep every hashtag genuinely relevant, no matter the quantity you’re testing.

Step three: run it long enough to mean something

One post proves nothing — a single post can soar or flop for a hundred reasons that have nothing to do with hashtags. Give each count at least three to four posts across two to three weeks before you judge it. Patterns need a little room to breathe before they tell you the truth.

Step four: compare the metric that actually matters — reach from hashtags

When you review, don’t just glance at likes. Open each post’s insights and look for reach, and specifically how many of the accounts reached were not already following you. On many posts Instagram will even show you how much of your reach came from hashtags. That non-follower reach is your real signal, because growth is all about getting in front of new, relevant people. Total up how each hashtag count performed on reach and let a clear leader emerge.

Here’s a simple way to organize what you find:

Hashtag count	Avg. reach	Reach from non-followers	Saves + shares	How it felt
Small set	Your number	Your number	Your number	Clean, tightly targeted
Medium set	Your number	Your number	Your number	Balanced reach
Fuller set	Your number	Your number	Your number	Wider, watch relevance

Fill in your own numbers as you go — I’m deliberately not inventing figures for you, because the only numbers that matter here are yours. After a few weeks, one row usually starts to shine. That’s your count. And the beautiful part? You found it, which means you can trust it far more than any blog’s blanket rule. If you’d like a deeper primer on reading these numbers with confidence, our guide on the social media metrics to track will help you tell the vanity numbers apart from the ones that genuinely signal growth.

Where should you actually put your hashtags — caption or comment?

This gentle debate comes up constantly, so let’s settle it kindly. You can put your hashtags directly in the caption or drop them in the first comment right after posting — and honestly, the reach difference between the two is negligible. Instagram reads both. So choose based on looks and feel, not on some rumored ranking boost.

Many people prefer the first-comment approach purely because it keeps the caption clean and readable, letting your words and your call-to-action shine without a wall of tags underneath. Others pop them at the bottom of the caption after a few line breaks so everything lives in one place. Either is fine. Just be consistent, and if you post them in a comment, do it immediately — you want those hashtags working from the very first minute your post goes live, not twenty minutes later after the early momentum has already passed.

Do hashtags work differently on Reels versus feed posts?

They can, and this is a lovely nuance once you’re comfortable with the basics. Reels lean heavily on Instagram’s recommendation engine to reach non-followers, so while relevant hashtags still help the platform understand and categorize your video, the caption text, audio, and on-screen content are doing a lot of the discovery work too. Keep your Reel hashtags tight and relevant, and pour your energy into a strong hook and a trending or fitting sound.

Feed posts and carousels still benefit meaningfully from a thoughtful hashtag set, since browsing and following specific tags remains a real discovery path for static content. So don’t abandon hashtags on your grid — just keep applying the relevance-first, test-your-count approach we’ve been building.

If you’re leaning into short-form video for growth, you’ll get more mileage pairing smart hashtags with genuinely creative concepts. This roundup of Instagram Reels ideas is a warm well to draw from when you want your video content to actually stop the scroll. And when a Reel does take off, understanding the mechanics behind it helps you repeat the magic — our guide on how to go viral on social media unpacks what really drives those breakout moments beyond any single hashtag trick.

What hashtag mistakes quietly waste your reach?

Let me save you some of the bruises I’ve collected over the years. These are the sneaky ones — the mistakes that don’t announce themselves but quietly cost you discovery.

• Chasing only the biggest, most crowded tags. It feels productive to grab tags with hundreds of millions of posts, but your content drowns there in seconds. Favor niche and mid-size tags where you can actually surface.
• Copy-pasting the exact same hashtag block on every single post. Reusing an identical wall of tags forever can look repetitive and stops serving your varied content well. Keep a saved bank, but tailor the set to each specific post.
• Using tags that don’t match the content. Slapping on a popular but irrelevant hashtag to “reach more people” backfires — it draws mismatched viewers who scroll past, and that weak early engagement can signal to Instagram that your post isn’t landing.
• Judging a hashtag count off one or two posts. Content variance is huge. Give your tests enough posts to actually mean something before you crown a winner or write off a count.
• Ignoring banned or spammy tags. Some hashtags get restricted because they attract spam, and using them can limit your post’s visibility. If a tag’s page looks empty of recent posts or full of junk, quietly drop it.
• Treating hashtags as a substitute for good content. No hashtag set can rescue a post that gives people no reason to stop. Hashtags amplify content worth discovering; they can’t manufacture interest. Put most of your love into making something genuinely worth finding.

How does scheduling make your hashtag testing effortless?

Here’s a gentle confession: figuring out your best hashtag count is the fun part, but actually remembering to rotate three different sets across three weeks, drop your tags in the first comment the instant each post goes live, and track the reach each one earned? That’s where good intentions go to die. Life happens. You forget which set went on which post, or you post in a rush and paste the same tired block again.

This is exactly why planning ahead is such a quiet game-changer. When you prepare and queue your posts in advance — captions, hashtag sets, and first comments all set — you can run a clean, honest experiment without holding it all in your head. You decide once, up front, which count goes on which post, and then everything publishes on schedule while you live your actual life. It turns a fiddly research project into something almost effortless, and it keeps your test fair because you’re not improvising under pressure.

Let’s put it all together

So, take a breath, because you’ve actually got everything you need now. The answer to how many hashtags to use on Instagram for growth was never hiding in someone else’s blog post — it was waiting in your own reach data, ready for you to test your way to it. You build a layered set of niche, mid-size, and community tags that genuinely match your content, you keep relevance first no matter the number, you rotate a few different counts across similar posts for a few weeks, and you let your own non-follower reach crown the winner.

Then you keep that count as your working default, refresh your tags to fit each post, and let scheduling carry the load so your experiment stays clean and your posting stays consistent. That’s the whole system. It’s not flashy, but it’s true, and true is what keeps working long after the trendy hacks and confident magic numbers fade.

You’ve got this. Go pull up your last few posts’ insights tonight and start noticing which ones reached the most new people — I have a feeling you’ll be a little surprised, and a lot more confident, by tomorrow.
