The Big, Medium and Small Hashtag Mix: Does It Still Work?

For years, a popular tip was to use an Instagram hashtag mix of big, medium and small tags on every post. The idea was to blend a few huge tags, some mid-sized ones and several tiny ones. But does that advice still make sense now that Instagram has changed its guidance?

If your question is a little different, these guides cover it: How Many Hashtags Should You Use on Instagram in 2026?; Instagram Hashtags in the Caption or the First Comment?.

This article explains where the mix came from, what has changed and how to keep the useful part of the idea. Rules shift, so please confirm the latest details in Instagram's official Help Center.

Where the big, medium and small mix came from

The mix grew out of a simple theory. Big tags have enormous numbers of posts, so yours disappears quickly. Small tags have few posts, so yours stays visible longer but fewer people look. A blend, the theory went, gave you a bit of both.

It was usually taught with a long list of 20 to 30 tags per post, split into thirds. That worked as a rule of thumb when long lists were common. It was never a proven formula, and nobody outside Instagram can say how tag size affects what a post gets.

The core question the mix tried to answer is still sensible: are my tags too broad to be useful, or so narrow that nobody follows them? That question is worth keeping, even if the old recipe is not.

What changed in the current guidance

In December 2025, Instagram announced through its creators account that it would gradually limit captions on posts and reels to 5 hashtags. Its Help Center page "Use hashtags on Instagram" says you can use up to 5 hashtags on a post. The rollout was described as gradual, so a reader may see differences.

Instagram also advised using fewer, more targeted hashtags rather than many generic ones, and avoiding generic tags such as #reels and #explore. It has said that hashtags matter less for reach than they once did.

Put simply, a fixed split into thirds of 30 tags is no longer possible, and the advice leans towards precision. That affects how we should treat the "big" part of the mix in particular.

Does the Instagram hashtag mix of big, medium and small still work?

The exact old recipe does not fit a five-tag limit. But a lighter version of the idea can still be useful as a thinking tool. Here is how to adapt it:

• Big (broad) tags: use rarely, if at all. They are the most generic, and Instagram has advised against generic tags.
• Medium (niche) tags: these are your main workhorses. They name a clear topic or community.
• Small (long-tail) tags: these are specific phrases that describe a single post very precisely.

With five slots, a sensible pattern might be zero or one broad tag, two or three niche tags and one or two long-tail tags. This is a starting point, not a rule, and no particular blend is guaranteed to perform better.

How to tell whether a tag is broad, niche or long-tail

Be honest about what you can and cannot know. Instagram does not give you a simple public number for how competitive a tag is, and you should be careful with any site that claims precise figures.

A practical way is to judge by how specific the phrase is:

1. Broad: one general word, such as "travel" or "food".
2. Niche: a clearer topic, such as "budget travel" or "vegan baking".
3. Long-tail: a specific phrase, such as "night train travel tips" or "vegan banana bread recipe".

The Tagbloom free tag generator labels suggestions as Broad, Niche or Long-tail using this idea. It is an estimate based on how specific the phrase is. It does not know live search volume, so use the labels as a guide only.

A simple way to choose tags for each post

Instead of filling a fixed quota, work from the post itself.

1. Write one sentence describing the post.
2. List the topic words in that sentence.
3. Turn them into possible tags, from general to specific.
4. Cut any that are generic or only loosely related.
5. Pick up to five that match the content best, leaning towards niche and long-tail.

For a fuller research method, see Instagram hashtag research for small accounts. It shows how to build a reusable pool so you are not starting from nothing every time.

Worked example: adapting the mix to five tags (hypothetical)

This is a made-up illustration, not a real case, and it shows no results. Imagine a small account about indoor climbing, and the next post is a reel showing three footwork drills for beginners.

1. Old approach: 30 tags split into 10 big, 10 medium and 10 small. This no longer fits the current limit.
2. Describe the post: "Three footwork drills for beginner climbers."
3. Broad option: a general climbing tag. It is generic, so the account decides to skip it.
4. Niche options: a bouldering tag, a beginner climbing tag and an indoor climbing tag.
5. Long-tail options: a climbing footwork tag and a climbing drills for beginners tag.
6. Choose five: it keeps two niche tags (beginner climbing, indoor climbing) and two long-tail tags (climbing footwork, climbing drills for beginners), plus its own brand tag.
7. Review later: after a few similar posts, it checks Instagram Insights to see how they compare.

With five slots, think in terms of precision. Lean on niche and long-tail tags, use broad tags sparingly, and always match the tag to the post.

What to watch out for

Whatever blend you choose, a few cautions apply:

• Do not chase size. A huge tag is not automatically better, and a tiny one is not automatically safer.
• Do not pad. Using all five slots is not required. Fewer, accurate tags are fine.
• Do not reuse one set forever. A copied list can drift away from the post.
• Do not forget the caption. Captions, keywords, alt text and the words spoken or shown in a video can also help Instagram understand a post.

Many of these are covered in Instagram hashtag mistakes that make posts look spammy.

How to test your own mix

Because nothing is guaranteed, the best evidence is your own. Instagram Insights shows metrics such as reach, saves, shares, likes, comments and profile visits. Exact menu names change, so look around if a label has moved.

A fair test is simple. Choose one type of post, such as reels on a single topic. Use one pattern for a few posts, for example three niche and two long-tail tags. Then try a different pattern for a few more. Compare the numbers, but keep in mind that a small sample can be misleading and many things other than tags affect results.

Frequently asked questions

Should I include any big hashtags at all?

You may not need to. Instagram has advised avoiding generic tags such as #reels and #explore. If a broad tag genuinely describes your topic, one is fine, but most of your slots are better spent on specific tags.

What is the best ratio of big to small tags?

There is no proven ratio. With a limit of 5, a sensible approach is mostly niche and long-tail tags, with a broad tag only if it fits. Test different patterns on your own posts and compare in Insights.

Do small hashtags get more reach?

Not necessarily. A small tag is less crowded, but fewer people may follow it. Reach depends on many things, including the content itself, and Instagram has said hashtags matter less for reach than they once did.

Conclusion

The old big, medium and small recipe was built for long tag lists, and it does not fit a five-tag limit. The thinking behind it still helps: avoid tags that are too generic, favour clear niche topics and add precise long-tail phrases where they fit.

Your next step: take your next post, write a one-sentence description, and choose up to five tags that are mostly niche and long-tail. Then compare the results with an earlier post in Insights.
