How to choose Instagram hashtags
Instagram cut the limit from thirty hashtags to five in December 2025, so almost every guide online is now wrong. With five slots the right tags depend on how big your account is — here's how to check one before you spend a slot on it.
The mistake almost everyone makes
Putting #love on a post from a 400-follower account does nothing. Not very
little — nothing. That tag receives millions of posts, its top slots are held by
accounts with audiences in the millions, and your post is buried within seconds of being
published.
The tags worth using are the ones where your post can realistically sit near the top for a while. That depends on your account size, which means the right hashtag for you is not the right hashtag for someone else, and any list of “best hashtags 2026” is guessing about you specifically.
Checking whether a tag is winnable before you use it
- Install InstaDesk and open instagram.com.
- Open a hashtag, or type one into the hashtag tool.
- InstaDesk compares the tag's post volume against your own follower count and tells you whether an account your size can compete in it.
- Build sets of the ones that fit, and reuse them in one click.
Hashtag collections — saving sets and reusing them — are free forever, along with all publishing. The fit check sits with the account insights tools, which come with free uses first.
A mix that works better than a list
Instagram cut the limit to five hashtags per post and Reel, rolled out from December 2025 — down from thirty. Most advice you will find online was written for the old cap and tells you to paste twenty-five tags. That advice is dead, and following it now means Instagram blocks the publish or strips the extras.
Five changes everything. There is no room for a spread of small, medium and large bets — every tag has to earn its place:
- Three or four small, specific tags (under ~50k posts). This is where an ordinary account can actually rank and stay ranked, and with only five slots it is where nearly all of them should go.
- At most one larger tag (500k+), if it genuinely describes the post. Occasionally something breaks out. Do not spend two slots on it.
- Specific over generic, always — and it matters five times more now.
#sourdoughbeginnerreaches people who want that.#foodwastes one of your five. - Do not pad. There is no advantage to using all five if only three fit. An irrelevant tag actively tells Instagram the wrong thing about who the post is for.
Instagram has said that tags are a much weaker ranking signal than they were, and that what the post is actually about matters more. Treat hashtags as a way of describing your post accurately, not as a lever to pull.
Where to put them
In the caption. Hiding tags in the first comment was a workaround for the days when people pasted thirty of them and did not want a wall of blue text under every post — at five it is no longer worth the extra step. InstaDesk still posts a first comment automatically if you want one, which is genuinely useful for a note or a link; it just is not a hashtag tactic any more.
Common questions
How many should I use?
Five is the maximum, since December 2025. Use fewer if fewer genuinely fit — there is no bonus for filling the slots, and an irrelevant tag tells Instagram the wrong thing about who your post is for.
Should I reuse the same set every time?
With only five slots, saved sets matter less than they did and accuracy matters more. Reusing a set that genuinely fits one kind of post is fine. Pasting the same five onto unrelated posts is the thing to avoid — it stops describing the post.
Do banned hashtags still exist?
Some tags have restricted or hidden results because of what gets posted to them. If a tag's page looks unusually empty, do not use it.
Are hashtags even worth it now?
Less than in 2019, and more than nothing. They are one accurate signal among several. The account that grows is the one making things people send to their friends — tags help the right people find it, they do not substitute for it.
