How to post to Instagram and Threads at the same time

Instagram and Threads do not take quite the same post. Threads stops text at 500 characters while Instagram allows 2,200, and the media or thread rules differ too.

Instagram vs Threads: what's different

	Instagram	Threads
Character cap	2,200	500
Images per post	10	10
Needs media	an image or a video	No
Long text becomes a thread	No	Yes
Comments inbox in fanout	Yes	Yes
Analytics in fanout	Yes	Yes

What fits both

Text: while both networks use the master draft, the counter holds you to the stricter cap, 500 characters (Threads). Give Instagram its own tab to use its full 2,200.
Images: both take up to 10, so the same set goes to both.
Media: Instagram needs an image or a video. A text-only post is flagged for Instagram. A video cannot be mixed with images in one post.
Over-limit text: on Threads it is published as a reply thread (up to 10 posts). Instagram does not thread, so over its 2,200 cap the post is flagged and you shorten it or give Instagram its own tab.

Post to both in fanout

Connect Instagram and Threads. Each login happens on the network's own permission screen.
Open the composer, write the master draft and select both accounts.
Check each tab. Both inherit the master text until you edit one; AI tailoring suggests a version for each, which you review before anything is published.
Attach media once. The same files go to both networks that accept them.
Publish now, or pick a date and time to schedule it to both.

Tips for this pair

A 1,000-character text becomes 3 posts on Threads, and fits Instagram as one post.
Instagram needs an image or a video, so every post to both needs media attached.
