Find hashtag ideas
Check hashtag sizes
Fill in the field above to get started.
From topic to a focused selection
Shortlist the ideas and keep the best-fitting tags. Instagram allows 5 hashtags per post in total (caption and first comment together).
Describe your content
Describe what your post shows. Get up to 30 Instagram hashtag ideas, including broad, medium, and niche options.
Check the shortlist in Instagram
Search each candidate in Instagram and look at the recent posts under it. Keep the tags whose posts look like yours.
Choose your final tags
Keep tags that match the post. Choose up to five, with specific tags first and no more than one broad tag.
What the sizes mean
The check shows how many public posts use each hashtag and sorts it into a size. The size tells you about the competition, not about your reach.
Large
- Posts with the hashtag
- 1 million or more
- What it means for you
- So many posts that yours sinks fast. Use one at most.
Medium
- Posts with the hashtag
- 50,000 to 1 million
- What it means for you
- A clear topic with an active community. A good core for your set.
Niche
- Posts with the hashtag
- under 50,000
- What it means for you
- Fewer posts, very specific. Ideal for your subject or your location.
Unknown
- Posts with the hashtag
- no number available
- What it means for you
- The count is missing, which doesn't mean zero. Search the tag in Instagram yourself.
How to find your five hashtags
Instagram allows up to five hashtags per post, caption and comments combined. So picking the right ones matters more than adding more.
Get ideas
Describe your post in a few words. You get 20 to 30 suggestions mixing big, medium and niche tags.
Check the sizes
Paste up to 30 candidates into the check and see how big each one is.
Look them up in Instagram
Open the tags you want to keep and scroll the latest posts. Do they look like yours?
Pick five
the specific tags for your subject and audience first, then one big tag at most.
From topic to tag
Good hashtags describe what's in the picture and who it's for. Four questions help you sort them.
Subject
What exactly does the post show? Mug, glaze, pottery wheel.
Audience
Who searches for it? Pottery beginners, gift shoppers.
Location
Is your place worth a tag? For local businesses, almost always.
Your own tag
A brand tag collects your posts when customers use it too.
Placing hashtags in your post
Caption or first comment, both work. Just stay at five in total. The caption generator adds fitting hashtags at the end of your caption right away.
In the Crowdbird scheduler you save your set with the draft and schedule the post for later. For TikTok, the TikTok hashtag generator counts views instead of posts.
Common mistakes
Only big tags
Your post gets lost among millions of others.
Tags that don't fit
If it's not in the picture, leave it out.
The same list every time
Pick fresh tags for each post.
More than five
Instagram doesn't allow more.
How many hashtags should I use on Instagram?
On Instagram, use no more than 5 hashtags per post in total (caption and first comment together). You can use fewer when only a few tags describe the content well. Start with the subject of the post, then add useful details such as the material, technique, or location. Don't fill the remaining spaces with unrelated tags just to reach five.
What is the 3 hashtag rule?
A three-hashtag approach is a way to keep your selection focused, not a requirement to use exactly three. You might choose one tag for the subject, one for a specific detail, and one for the intended audience. Instagram allows 5 hashtags per post in total (caption and first comment together), so three is fine if those three do the job.
Is this Instagram hashtag generator free?
Yes, you can generate Instagram hashtag ideas without paying or creating an account. Describe your content, get up to 30 ideas and copy the ones you want to check. Your generator inputs are not stored. The tool on this page is set to Instagram. TikTok has its own page, which also shows public view counts.
Can hashtags get my Reel 100k views?
No, choosing hashtags does not make 100k views or any other view count predictable. The generator suggests terms that describe your content and does not predict performance. Use relevant tags, then review your Reel's own results. A popular tag tells you nothing about how many people will watch your video.
Should I put Instagram hashtags in the caption or first comment?
Either placement is allowed: Instagram supports hashtags in captions and comments. Choose the option that fits how you prepare your posts, and keep your selection to five, with no second batch in the comments. If you schedule through Crowdbird, you can prepare an Instagram first comment alongside the post, except for Stories.
Does the hashtag generator detect banned or restricted hashtags?
No, the generator suggests ideas and does not check a tag's status. Before publishing, search a questionable tag in Instagram and look at the recent posts. Leave it out if the results look spammy, if you can't assess it, or if the content is unrelated to your post.
How do I create my own hashtag on Instagram?
Type # followed by your chosen text in your own post's caption or comment. Numbers are allowed, but spaces and special characters such as $ or % won't work. For a shop tag, keep the spelling recognizable and search it first to see what content already uses it. Your own tag still takes one of the five available spots.
