Instagram hashtag checker

Instagram’s Help Center article “Use hashtags on Instagram” (help.instagram.com/351460621611097, read on 7 October 2026) says: “You can use up to 5 tags on a post. If you include more than 5 tags on a single photo/video, your comment won’t post.” A Social Samosa report dated 19 December 2025 says Instagram announced it would limit the hashtags in a caption to five, and quotes Instagram: “Instagram will gradually update the number of hashtags that you can include in a caption for a reel or post to five.” Meta’s developer reference for publishing a post through its API, last updated 28 September 2026, still lists a maximum of “2200 characters, 30 hashtags, and 20 @ tags” for a caption.

So the two figures disagree, and this page shows both. For what you type in the app, five is the number Instagram’s own help article gives, which is why the page offers a set of five. The same article says tags can go in the caption or in comments, and that tags from private profiles won’t appear publicly on hashtag pages. We can’t say why the API reference still lists 30.

The number beside a tag is the post count Instagram shows for it. It tells you how many posts have used the tag. It does not tell you how many people a post using it will reach, how often anyone browses it, or how new posts are shown there, and nothing on this page claims any of that. The four bands are our own rough sizes, chosen to make a long list easier to scan.

Instagram’s own line on the change, as Social Samosa quoted it, was that “using fewer (up to 5) more targeted hashtags, rather than many generic ones, can improve both your content’s performance and people’s experience on Instagram”. Choose tags that describe the post, and look at a tag’s page before you rely on it.

It is our own rule, not a recipe with evidence behind it. We take up to two tags under 100K posts, two between 100K and 1M and one between 1M and 10M, with Instagram’s closest matches first and your own tag first in its size. If a size has too few tags, the gap is filled from the others, and if the results hold fewer than five tags you get fewer. The aim is only that a set isn’t all enormous tags or all tiny ones.

Tip: A tag that suits the post beats a tag that only has the right size. Drop any tag in the five that doesn’t describe what you are posting.

Instagram’s search returns related tags, not always the one you typed, and the results can lean towards one region and may leave a tag out. A tag missing from the list can still exist. The page shows your tag as its own row either way, with its size when it appears in the results and a note when it doesn’t. Look it up in Instagram’s own search to see its page.

The tags in Instagram’s search results are letters, numbers and underscores with no spaces, so that is how this page reads a tag. Instagram’s Help Center adds that numbers are allowed in a hashtag but spaces and special characters such as $ or % won’t work. “skin-care” has a hyphen, so it isn’t checked as a tag as typed, though the related tags below it are. Tags in other scripts, such as Hindi or Arabic, are read the same way.
