The best Instagram hashtags are not a list you copy. They are a mix of types: a few broad ones for the topic, more specific ones for the niche, one that belongs to your own brand or series, and one for the place if the post is local. What makes any one of them "best" is whether the people you want search for it and whether it describes the post, and no network publishes data on which hashtags perform. This page gives the types, a way to build a set for your own account, and the limits a scheduler has to respect.
The types of Instagram hashtag
| Type | What it is | What it is for | Watch for |
|---|---|---|---|
| Broad topic | A word for the whole subject, such as the craft, the sport or the food | Telling Instagram and readers what the post is about | Millions of posts use it, so a new post is buried at once |
| Niche | A narrower phrase that only your audience would type | Reaching people who already care about the exact thing | Too narrow and almost nobody follows it |
| Community | A tag a group of people use among themselves | Sitting next to posts of people with the same interest | Do not use a community tag your post has nothing to do with |
| Branded | A tag you own: your name, a product line, a series | Collecting your own posts in one place and letting others find them | It only works once you use it every time |
| Location | A city, region or venue | Local searches and visitors | Only when the post really is from there |
| Event or season | A festival, a launch week, a holiday | Being found while the topic is live | The tag is dead after the event: do not reuse it |
A set that has one or two of each of the first four types is a sound default. The proportions are a habit, not a rule from Instagram.
How to pick them for your own account
- Start from the post, not the list. If a hashtag does not describe what is on the picture or in the video, leave it out. A tag that does not fit costs a place in a short set and earns nothing.
- Look at accounts like yours. Open three or four accounts of the same size in your field and note which tags they put on posts that did well. Copy the kind, not the exact set.
- Mind the size of the tag. Search the tag in the app and look at how many posts it has. A tag with tens of millions of posts moves too fast to be seen in; a tag with a few hundred has no readers. A middle sized tag is usually the one worth having, and the app shows the number.
- Test and keep a note. Change one or two tags between similar posts and write down what happens. The only evidence that counts is your own insights, because the same tag does different things for different accounts.
- Retire what stops fitting. Tags age. Check a saved set every few months.
None of this is measured by Instagram, and no scheduler, Preflight included, can tell you a tag will reach people. What Preflight can do is keep the set correct and in the right place.
How many, and where
The rules sit in hashtag rules by network and the Instagram limits, and in short they are these:
- Through the API a caption takes 30 hashtags and 20 mentions. A live test on 30 October 2026 took 30 and refused 31.
- The Instagram app itself has allowed only 5 per post since December 2025, so a set of 15 can be scheduled through a tool but could not be typed in the app. The count that suits your account is a choice, and a short, fitting set is the safer one.
- Hashtags can go in the caption or in a first comment. A first comment keeps the caption short, and Preflight posts it straight after the post.
Using the types in Preflight
- Save each type as a group. Write the hashtags in a caption, then use *Saved texts* and *Save its hashtags as a group*. The groups belong to the workspace, so a team shares the same branded and location sets.
- Insert a group when you write. Pick one group for the topic and add the niche tags for this post, instead of pasting one long block under every post.
- Watch the counter. The Instagram preview shows the count against 30 and flags a caption that is over, before it is scheduled.
- Move them to a first comment if you would rather keep the caption clean. The first comment is optional, is posted as your account when the post goes live, and if it is refused the post still goes out.
- Write a different set for each network. A tag set for Instagram is not the right one for TikTok, where the app takes five, or for YouTube, where more than 60 makes it ignore all of them. See the limits of each network.
Scheduling and saved groups work on every plan, the free one included. The same checks run from the API.
What to avoid
- Copying a "best hashtags" list of someone else's account. Their audience is not yours, and a set repeated unchanged on every post looks the same to readers and to you.
- Tags that do not fit the post. They are the most common waste and the easiest to remove.
- A wall of tags. Even where 30 are allowed, a short fitting set is easier to keep and to review.
Limits from Instagram's API (live test of 30 October 2026) and the app; the advice on choosing hashtags is editorial and not a rule of Instagram.
Questions people ask
- What are the best hashtags for Instagram?
- There is no single best list. A good set mixes a broad topic tag, narrower niche tags, a branded tag of your own and a location tag when the post is local, all describing what the post really shows.
- How do I find good Instagram hashtags for my niche?
- Search a word for your topic in the app, look at the number of posts each tag has, and note the tags that accounts of your size use on posts that did well. Prefer middle sized tags over the biggest ones.
- Should I put Instagram hashtags in the caption or the first comment?
- Either works. A first comment keeps the caption short. Preflight can post the first comment straight after the post, and if the comment is refused the post still goes out.
- Can I save a set of Instagram hashtags to reuse?
- Yes. In the Preflight composer write the hashtags in a caption, then save them as a hashtag group from the Saved texts menu and insert the group into later posts. Groups are shared across the workspace.
- Do hashtags increase Instagram reach?
- No network publishes data that proves a tag will reach people, and neither does a scheduler. Hashtags describe a post so it can be found; treat them as labels and judge a set by your own insights.
