An Instagram Collab Post (or Instagram collaboration post) is a Feed post or Reel that you create with one or more other accounts. When you invite collaborators and they accept, the post appears on all collaborators' profiles and is distributed to all of their followers. So you share reach: your post is seen by your audience and by each collaborator's audience, which helps you grow faster and get more engagement.

The Instagram collab feature is different from tagging: with a collab post, the content shows on the collaborator's profile and in their feed, not just as a tag. For Reel specs, see our Instagram Reel dimensions and Instagram Reel length. For captions, use our Instagram Reels caption generator.

To create an Instagram Collab Post and invite a collaborator before publishing:

1. Create your post or Reel – Add your photo, video, or Reel and edit as usual. Go to the final screen before posting (where you add caption, location, etc.).
2. Tap Tag People – On that screen, tap Tag People.
3. Tap Invite Collaborators – In the Tag People flow, tap Invite Collaborators (or Add Collaborators). Search for the account you want to collab with, select them, and send the invite.
4. Post – Finish and tap Post. The collaborator will get an invitation; they must accept for the post to appear on their profile. Until they accept, the post is only on your profile.

That's how to collab on Instagram when creating a new post or Reel. For Reel length and dimensions, see our Instagram Reel length and Instagram Reel dimensions. For captions, use our Instagram Reels caption generator and best time to post on Instagram.

You can invite collaborators after the post is live. Open the post or Reel → tap the three dots (top right) → tap Edit → tap Tag People → tap Add Collaborators. Search for the account, select them, and send the invite. They must accept for the post to appear on their profile; once they do, the post will show on both profiles and share reach.

This is useful if you forgot to add a collaborator before posting or want to add someone later. For more growth, pair collab posts with our best time to post on Instagram, Instagram caption generator, and how to repost on Instagram.

Instagram Collab Post benefits include:

• Share reach – The post is shown to your followers and to each collaborator's followers, so you reach more people without paying for ads.
• More engagement – Likes, comments, and shares come from all collaborators' audiences, which can boost the algorithm and discovery.
• Grow faster – Collaborators' followers may discover you and follow you; you build authority and community with other creators.
• Fresh perspectives – Co-authored content often performs well because it combines different styles and audiences.

Use collab posts together with strong captions and timing. See our Instagram Reels caption generator, Instagram caption generator, and best time to post on Instagram.

You can invite up to 20 collaborators on a single Instagram Collab Post or Reel (the exact limit may vary by region and app version; check the app). The original author keeps ownership and control: if they delete the post or remove a collaborator, the post is removed from all collaborators' profiles. Collaborators cannot remove the post from the original author's profile.

If you don't see Invite Collaborators, update the Instagram app to the latest version. The Instagram collab feature may roll out by region or account type. For Reel and Story specs, see our Instagram Reel dimensions, Instagram Reel length, and Instagram Story dimensions.
