How to Choose Instagram Hashtags Now That You Only Get Five
For years the advice was "use all 30 hashtags". That's over. On 18 December 2025, Instagram announced it would gradually limit hashtags in a post or reel caption to five. Its reasoning: a few targeted hashtags work better, for both reach and for people browsing, than many generic ones.
With only five slots, every tag has to earn its place. Here's how to choose them.
What hashtags do now
Hashtags still help Instagram understand what a post is about, and people can still search for them. But they're one signal among many: your caption text, what's in the image or video, and how people engage all matter too. No set of hashtags guarantees likes or followers. They help the right people find a post that's already good.
The five-slot formula
A simple mix that works for most accounts:
| Slot | Type | Example: a home-cooked biryani photo |
|---|---|---|
| 1 | What this exact post shows | #hyderabadibiryani |
| 2 | The broader niche | #indianfood |
| 3 | The community or audience | #homecooking |
| 4 | Location, if relevant | #puneeats |
| 5 | Your own branded or series tag | #sundaysupperclub |
Swap slots to fit the post. A travel photo might use two location tags; a product post might use the product category and your brand.
Rules for picking each tag
- Be specific. #hyderabadibiryani describes the post; #food describes millions of unrelated ones.
- Make it match what people can see. A tag that doesn't match the image misleads viewers and doesn't help.
- Skip generic "reach" tags. Instagram has said generic tags such as #reels or #explore don't help.
- Check the tag first. Tap it and look at recent posts. If they're unrelated, spammy or nothing like yours, choose another.
- Mix sizes. Very large tags bury your post in seconds; tiny ones nobody searches. Mid-sized, active tags in your niche are the sweet spot.
Build reusable lists, then trim
Most accounts post about a handful of recurring topics. Create a short list of good, checked tags for each topic, say 10 to 15 per category, and pick the best five for each post. Rotating within a list keeps you from repeating an identical block on every post, which tells Instagram nothing new about each one.
Keep your lists somewhere you can copy from quickly, and prune them every month or two: remove tags that have turned spammy and add new ones you've seen working in your niche.
Write the caption for search, too
Instagram search reads captions as well as hashtags. Name things plainly: "Hyderabadi chicken biryani, slow-cooked on a Sunday" says more than an emoji and five tags. Think of the hashtags as a supplement to a descriptive caption, not a replacement for one.
Captions or comments?
Instagram's announcement covers captions. Whether hashtags in comments count toward the same limit isn't clearly settled, so the safe approach is to keep the total for a post at five or fewer, and put them in the caption.
Other platforms are different
Each platform treats hashtags differently. On some, one or two well-chosen tags are plenty; on others, tags matter less than keywords in the text. Don't paste the same block everywhere. Tailor it to each platform's conventions.
Common mistakes
- Pasting an old 30-tag block from your notes app. Trim it to five.
- Using banned or broken tags. If a tag shows few or no recent posts, Instagram may have restricted it.
- Tagging for the algorithm, not for people. Ask: "Would someone searching this tag be happy to find my post?"
- Expecting tags to do all the work. A strong first image, a clear caption and consistent posting matter more.
A faster workflow on your phone
If you post regularly, keeping topic lists of hashtags you can copy in a tap saves time. With today's limit, copy a list and keep only the five that fit the post.
Ready-made hashtag lists: Hashtags Creator (free, by the author of this guide) has category collections of popular hashtags you can customise: delete irrelevant tags, edit your lists, and copy tags to paste into Instagram and other social apps. Its lists predate the five-tag limit, so trim what you copy to the five that best fit each post.
Summary
- Five tags maximum per post or reel.
- One for the post, one niche, one community, one place, one brand.
- Specific beats generic; check each tag before using it.
- Keep topic lists and rotate.
- Describe the post in the caption, too.
