Instagram Video Size: Feed, Reels and the Ratio That Survives
Quick answer
Instagram feed video works at 1080 x 1350 in 4:5, and reels at 1080 x 1920 in 9:16. Instagram documents a 720 pixel minimum resolution and a 30 fps minimum frame rate for reels and stories; the pixel sizes themselves are convention rather than published specification.

What the table does not tell you
- Feed video at 4:5 takes more vertical space than square and still appears in the grid without the aggressive crop a 9:16 upload suffers there.
- A reel posted at 4:5 publishes but gets pillarboxed in the full-screen player. Decide which surface the video is for before exporting, not after.
- Instagram documents 720 pixels as the minimum resolution and 30 fps as the minimum frame rate. Both are floors, and footage shot at 24 fps will be resampled.
- Exporting above 1080 pixels wide achieves nothing for feed video. Instagram re-encodes everything, and the extra data is discarded before anyone sees it.
Stop resizing the same asset five times
Crowbert formats one upload for every platform it publishes to, so a single feed video goes out at the right dimensions everywhere without a round trip through a design tool.
Common questions
What size should Instagram video be?
1080 x 1350 at 4:5 for feed, 1080 x 1920 at 9:16 for reels. Instagram publishes the ratios and a 720 pixel minimum rather than these exact figures.
What is the minimum video quality Instagram accepts?
720 pixels of resolution and 30 frames per second, both documented for reels and stories.
Should feed video be square or 4:5?
4:5 in almost every case. It occupies more feed height for the same content, and square offers no advantage now that the grid previews at 3:4 anyway.

Where these numbers come from
Figures marked “not published by Instagram” are working conventions rather than documented specifications. Everything else comes from the documentation above.
