Instagram274 / 2,200 Unicode code pointsfits above the fold

Instagram can't publish without an image or a video.

Counted in Unicode code points: one plain character is one, and a link costs its full length.

What Instagram hides, and where

The feed clamps the caption to two lines and hides the rest behind "… more". Two lines is roughly 125 characters in the feed column, which is where that number in every guide comes from - it is a consequence of the clamp, not a rule Instagram applies. A hashtag block at the top of the caption therefore spends the entire visible caption on hashtags.

Three posts Instagram only half shows

  1. Hashtags firstSix hashtags, then the caption.The two visible lines are hashtags. Everything a reader would have read is behind the fold from the first frame.
  2. The credit line"📸 shot by @someone" opening the caption.The credit uses the first of two lines. Moving it to the end costs the photographer nothing and buys back half the visible caption.
  3. A Reel with a long captionA single video and 900 characters of context.The caption sits over the video and clamps harder than in the grid. The first sentence is the whole caption for most viewers.

Only on Instagram

  • JPEG only - the publishing API rejects PNG.
  • At most 30 hashtags, counted inside the 2,200-character caption.
  • A single video publishes as a Reel.
  • A hard cap of 100 API-published posts per rolling 24 hours.

Questions

Is this Instagram post preview free?
Yes. There is no login and no upload: it runs entirely in your browser, and nothing you type or attach leaves your device.
Do hashtags count toward the 2,200-character Instagram caption?
Yes. Up to 30 hashtags are allowed and every one of them is spent out of the same 2,200 characters, so a large tag block is a real chunk of the caption. Putting the tags at the end keeps them out of the two lines the feed shows.
Does the preview match what Instagram actually shows?
It is the same chrome our studio uses before a post publishes: Instagram's current header layout, action row and media grid, in either of Instagram's themes. Engagement numbers are decorative, as in every scheduler's preview.
Where does Instagram cut the post off with "… more"?
Instagram shows 2 lines in the feed, then "… more". Reported at about 125 characters on desktop and 125 on a phone - the same 2 lines at two widths. No platform publishes that threshold, so the preview measures its own clamp at the width you are viewing instead of trusting a character count - switch it between desktop and phone and watch the fold move.
How long can an Instagram post be?
2,200 characters. Counted in Unicode code points: one plain character is one, and a link costs its full length.

Where these numbers come from: our sourced Instagram spec page, every figure carrying its citation and the date we last checked it.
