Instagram Hashtag Limit 2026: How Many to Use
September 25, 2026 · 4 min read · By Wavnil
Key takeaways
- Since December 2025, Instagram limits posts and Reels to 5 hashtags, down from 30.
- Instagram's advice: a few targeted hashtags beat many generic ones.
- Choose five specific tags that describe the post, not the most popular ones.
- Other platforms have their own rules: YouTube ignores every hashtag on a video that has more than 60, and Threads allows one topic tag per post.
Instagram allows up to 5 hashtags per post or Reel in 2026. The platform announced the limit in December 2025, down from the 30 hashtags that were allowed for years, and rolled it out gradually. Instagram's own advice is to use "fewer (up to 5) more targeted hashtags, rather than many generic ones".
Below: what exactly changed, how to pick your five, and how the rules differ on TikTok, YouTube and Threads, so you can adapt your hashtag habits in a few minutes.
What changed in December 2025
On December 18, 2025, Instagram announced through its @creators account on Threads that posts and Reels would be limited to five hashtags, as reported by Social Media Today. A few key points:
- The old limit was 30 hashtags per post.
- Instagram had tested a limit of three before settling on five.
- The stated reason: using fewer (up to five) targeted hashtags "can improve both your content's performance and people's experience on Instagram", while limiting spammy tag stuffing.
- The rollout was gradual, so some accounts saw the limit before others.
Instagram hasn't published a detailed rule for captions that go over the limit, and behaviour varied during the rollout. The safe approach is simple: never use more than five, especially in scheduled posts, since there's no one there to fix the caption at publication time.
Do hashtags still matter on Instagram?
Less than they used to. Instagram's head Adam Mosseri has repeatedly said that hashtags no longer significantly affect reach: recommendations depend mostly on how people interact with your content.
Hashtags still do two useful things:
- They describe your content, helping Instagram and people understand what a post is about.
- They connect you to niche communities, such as a local tag (#lyonfood) or an event tag (#websummit2026).
How to choose your 5 hashtags
With only five slots, every tag needs to earn its place. A simple framework:
| Slot | Type | Example for a Lisbon food blogger |
|---|---|---|
| 1 | One category tag | #foodblogger |
| 2 | A niche topic tag | #pasteldenata |
| 3 | A location tag | #lisbonfood |
| 4 | A community or audience tag | #lisbonexpats |
| 5 | Your branded or campaign tag | #eatwithana |
A few rules of thumb:
- Prefer specific over popular. A tag used by millions of posts buries yours within seconds.
- Describe the post, not your account. Tags should match what's actually in the image or video.
- Don't reuse the same five every time. Adapt them to each post's topic.
- Put them at the end of your caption so your first line (the hook) stays visible.

Hashtag rules on other platforms
Each network handles hashtags differently:
| Platform | Hashtag rule |
|---|---|
| 5 per post or Reel | |
| TikTok | No separate limit; hashtags count toward the 4,000-character caption |
| YouTube | Up to 3 shown above the title; more than 60 and all hashtags on the video are ignored |
| Threads | One topic tag per post |
| X | No limit, but each hashtag uses some of your 280 characters |
The YouTube rule comes from its hashtag policy: "If a video or playlist has more than 60 hashtags, we'll ignore each hashtag on that content." On Threads, Meta explains that you can only tag one topic per post because it makes it easier for people who care about that topic to find and read your post (Threads).

Adapt the same post for each network
The 5-hashtag limit makes one-size-fits-all captions harder: a caption with 10 hashtags that worked on TikTok now needs trimming for Instagram. In Wavnil, you write a post once and then adjust the text for each channel before it's scheduled, so each network gets hashtags that fit its rules. Combine it with the right Instagram post sizes and the best time to post for a complete routine.
In short
Five hashtags maximum on Instagram, chosen for precision rather than popularity. Hashtags help describe your posts, but your content drives reach. To adapt and schedule your captions for every network, try Wavnil free for 7 days.

Frequently asked questions
How many hashtags can you use on Instagram in 2026?
Five per post or Reel. Instagram announced the limit in December 2025 and rolled it out gradually, replacing the old maximum of 30. It had tested an even lower limit of three before settling on five. Stay at five or fewer so your posts, including scheduled ones, publish without issues.
Do hashtags still work on Instagram?
They help Instagram understand what a post is about, but they're a small factor. Instagram's head Adam Mosseri has repeatedly said hashtags no longer have a big impact on reach, which now depends mostly on how people engage with your content. Use a few precise tags and focus on the content itself.
Should I use broad or niche hashtags?
Mostly niche ones. A broad tag like #travel is shared by millions of posts, so yours disappears in seconds. Specific tags such as #lisbonfoodguide describe your post precisely and reach people looking for exactly that. A good mix is one fairly broad tag and four specific ones.
How many hashtags should I use on TikTok?
TikTok has no separate hashtag limit: hashtags simply count toward the caption, which can hold up to 4,000 characters in the app. Three to five relevant hashtags are usually enough. Like on Instagram, specific tags describe your video better than a long list of generic ones.
