How many hashtags can you use on Instagram?
Five. In December 2025 Instagram's @creators account announced that posts and Reels move to a limit of five hashtags, down from the 30 that held for years. Adam Mosseri, the head of Instagram, explained it this way: a few specific tags perform better than a long list of generic ones.
So when a guide tells you to use 20 to 30 hashtags, it was written before the change. You'll also see three quoted here and there, from reports of an earlier test; the announced limit is five.
What happens if you use more than five?
Reports differ: some accounts see the extra tags ignored, others are stopped at publishing. Instagram rolled the change out gradually, and Meta's developer documentation for apps that publish to Instagram still lists the older figure of 30. None of that changes the practical answer: write to five and you're safe everywhere.
Tags in the first comment are a common workaround from the 30-tag days. Treat them as part of your five rather than a way around them.
Do hashtags still help reach?
Less than they used to. Instagram has said for a while that hashtags help it understand what a post is about, which helps in search and topic pages, but they aren't what decides how many people see it. What a post says, who watches it to the end, and the conversation underneath matter more.
That's the real point of the limit: five specific tags describe a post better than thirty broad ones ever did.
How to choose your five hashtags
- One or two specific to the topic: what the post is actually about, as people would search it.
- One for your niche or community: the tag your ideal follower already browses.
- One local tag, if you serve a city or region.
- One of your own, if you run a branded tag people use.
- Skip the giant generic ones. Tags used on hundreds of millions of posts tell Instagram almost nothing.
Hashtag habits on other networks
Check the caption length on each network with the social media character limits table, or count an Instagram caption with the Instagram character counter.
- Threads: one topic tag per post.
- X: one or two at most; more reads as spam.
- LinkedIn: three to five specific ones.
- TikTok: a handful of specific tags in the caption.
What grows an account now that hashtags count less
Conversation. Replies under a post keep it in front of people while it's new, and a commenter who gets a real answer comes back. That's the gap PersonaXpand fills. Disclosure: it's our product. It drafts replies to your Instagram comments in your own voice for you to approve with a tap, and posts the same idea to your other networks, each version written for its network.
