How Many Hashtags to Use in 2026, by Platform

As of October 2026, use up to 5 hashtags on Instagram (its limit since December 2025), 1 to 3 on YouTube (which ignores all hashtags on a video with more than 60), no more than 2 on X, as its help center advises, and 3 to 5 on TikTok and LinkedIn. QuickVeed's free Hashtag Generator suggests a mix per platform.

Fewer, specific tags beat long lists everywhere. Most hashtag advice online was written when Instagram allowed 30 and “more is better” seemed to work. The rules have changed. Below are the limits from each platform's own pages, what the numbers mean in practice, and a quick way to choose the few tags worth using.

The short answer

Instagram: up to 5 hashtags per post or reel, a hard limit announced by Instagram in December 2025. YouTube: as many as you like up to 60, but up to three show by the title, so 1 to 3 strong ones is enough. X: 2 or fewer, per its help center. TikTok and LinkedIn publish no number; 3 to 5 relevant tags is a sensible default.

Key takeaways

• Instagram now allows up to 5 hashtags in a reel or post, and says fewer, targeted tags work better than generic ones like #reels or #explore.
• YouTube shows up to three hashtags by the title and ignores all of them if a video has more than 60.
• X's help center recommends no more than 2 hashtags per post.
• Hashtags tell a platform what a video is about; the hook, captions and spoken words do the same job, and matter more.
• Mix one broad tag, two or three niche tags and one branded tag.

Hashtag limits by platform (checked October 2026)

Two of these are hard rules (Instagram's cap and YouTube's 60-tag rule) and one is official advice (X). For TikTok and LinkedIn we couldn't find a number on their own help pages, so treat 3 to 5 as a starting point to test, not a requirement. Be wary of any article that quotes a precise “optimal” number without a source.

Instagram: the 5-hashtag limit

In December 2025, Instagram's @creators account announced that Instagram would allow up to 5 hashtags in a reel or post, rolling out gradually. Before that, the limit had been 30, and Instagram had tested lower caps for about a year, according to Social Media Today's report.

Instagram's own advice with the change was to use fewer, more targeted hashtags rather than many generic ones, and it singled out tags like #reels and #explore as not helping content reach Explore. In practice:

• Pick tags people actually browse for your topic: #sourdoughbaking rather than #food.
• Put the most important tag first. If an old post had more than five, edit it down before reposting or boosting.
• Let the caption do the rest. Instagram reads your caption, on-screen text and audio too, so describe the video in plain words.

YouTube: 60 is the ceiling, 3 is what shows

YouTube's hashtag policy says that if a video or playlist has more than 60 hashtags, YouTube ignores every one of them, and it warns against adding too many. Up to three hashtags that YouTube considers most engaging appear by the video's title, and hashtags in the title or description link to a page of other videos with the same tag.

For a Short or a regular video, one to three specific hashtags in the description is plenty. Put one in the title only if it reads naturally. Hashtags are a small signal compared with the title, the first seconds and retention; see how to get more views on YouTube Shorts and check your title fits with the free YouTube title length checker.

TikTok, LinkedIn and X

TikTok

TikTok uses captions, hashtags, sounds and the content of the video itself to work out who should see it. We couldn't find a recommended hashtag count on TikTok's own help pages. Three to five tags that describe the topic and community (for example, a niche tag and a product-category tag) is a reasonable default; a long block of trending tags unrelated to the video doesn't help the right people find it.

LinkedIn

LinkedIn lets you add hashtags anywhere in a post. Use a few professional tags your audience follows, such as an industry or a skill, and skip slang. Put them at the end so the post reads cleanly.

X

X's help center recommends using no more than 2 hashtags per post, and notes that spaces or punctuation inside a hashtag stop it from working.

How to choose the right hashtags

With only a handful of tags, each one has to earn its place. A simple mix:

1. Write one sentence describing the video, as if to a friend.
2. Search each candidate tag in the app. Look at the top posts: are they like yours? If not, drop it.
3. Prefer tags with an active community over the biggest numbers.
4. Keep a short list of branded and niche tags for recurring series, and reuse them consistently.

QuickVeed's free Hashtag Generator speeds up the first draft. Type a topic or caption (up to 300 characters), add a brand name if you like, pick TikTok, Instagram, YouTube Shorts, LinkedIn or X, and it returns about 20 to 30 tags in broad, niche and branded groups, in the language you wrote in. It's free with no sign-up and a fair-use limit per hour. Choose the best few for the platform; don't paste all of them.

What matters more than hashtags

• The first two seconds. A clear hook decides whether anyone watches; see hooks for short videos.
• Captions. Many people watch muted, and burned-in captions also tell the platform what's said. QuickVeed's auto subtitles add them in one of 11 styles. A transcript costs 1.5 credits a minute, rounded up, and a burned-in copy 1 credit a minute with a 3-credit minimum, so captions on a 1-minute clip cost 5 credits.
• The caption text. A plain sentence about the topic helps search inside each app.
• Consistency. A recurring series with one branded tag builds a library people can browse.

Frequently asked questions

How many hashtags can you use on Instagram in 2026?

Up to 5 per reel or post. Instagram announced the cap in December 2025 and rolled it out gradually; the old limit was 30.

How many hashtags should I use on TikTok?

TikTok doesn't publish a number. Three to five relevant tags that describe the topic and community is a sensible default to test.

How many hashtags should I use on YouTube Shorts?

One to three. YouTube shows up to three by the title and ignores all hashtags on a video that has more than 60.

Do hashtags still work in 2026?

Yes, as a signal of what a post is about, alongside the caption, on-screen text and speech. They rarely make a weak video take off.

Should I use #fyp or #reels?

They're too generic to describe your video. Instagram specifically says tags like #reels and #explore don't help content appear in Explore.

Where should hashtags go: caption or comment?

Put them in the caption or description. On YouTube, the description or title; on X and LinkedIn, at the end of the post.

Try it with your own video

Pick your hashtags with the free generator, then make the video itself easier to watch with captions. Upload a short video, pick a caption style and judge the captions for yourself.
