Meta recommends 1440×2560, not 1080×1920
Every Meta Ads Guide placement page — Instagram Reels, Instagram Stories, Facebook Reels, Facebook Stories — states 1440×2560 as the recommended resolution for 9:16, and 1440×1800 for the 4:5 feed placements. The 1080×1920 figure republished across the rest of the web is what Meta accepts, not what it recommends.
The floor is far lower again: 250 pixels wide for most placements, 120×120 on Facebook Feed, and 500 pixels for Reels ads of thirty seconds or more. Meta also allows a 1% aspect-ratio tolerance, which is why a 1080×1919 export does not get rejected.
Meta disagrees with Meta about duration
The Ads Guide gives Instagram Stories and Instagram Feed as one second to sixty minutes. Meta’s own video-requirements one-sheeter gives one to a hundred and twenty seconds for the same placements. Facebook Stories is three minutes on one document and a hundred and twenty seconds on the other; Facebook Feed is 241 minutes against 240.
Both are Meta, neither cites the other, and there is no note anywhere saying which supersedes which. Both are shown on this page, each labelled with the document it came from.
Instagram Reels is the only placement with a zero-second floor
Every other Meta placement states a minimum of one second. Instagram Reels states zero. It is almost certainly an editorial slip rather than a real difference, but it is what the page says, and guessing which of two Meta numbers is a typo is exactly the judgement a reference should not be making silently.
Meta publishes no safe zone for 4:5
The 14% top, 35% bottom and 6% sides that govern Reels and Stories are published for 9:16 ads only. For Instagram Feed at 4:5 and 1:1, Meta says to keep the bottom and side edges clear — notably not the top — but publishes no percentage or pixel margin at all. The preview above therefore shows no overlay on the feed placements, because inventing one would be worse than leaving it out.
The red areas come from the safe-zone reference, which measures each platform’s own template and shows where every margin came from.
FAQs
Frequently Asked Questions
What are the Meta ad specs for Reels?
Instagram Reels and Facebook Reels both take 9:16 at a recommended 1440×2560, in MP4 or MOV up to 4 GB, with H.264 video, square pixels, a fixed frame rate, progressive scan and stereo AAC audio at 128 kbps or above. Instagram Reels publishes a ceiling of 15 minutes; Facebook Reels publishes no ceiling. Minimum width is 250 pixels, rising to 500 for ads of 30 seconds or longer.
What size should an Instagram ad be?
For Reels and Stories, 9:16 at Meta’s recommended 1440×2560 — though anything from 250 pixels wide is accepted, and 1080×1920 is the common export. For the feed, 4:5 at a recommended 1440×1800. Meta allows a 1% tolerance on the ratio, so an off-by-one export is fine.
How long can a Facebook or Instagram ad be?
Meta’s answer depends on which of its documents you read. The Ads Guide says up to 60 minutes for Instagram Feed and Stories, 15 minutes for Instagram Reels, 3 minutes for Facebook Stories and 241 minutes for Facebook Feed. Meta’s video-requirements one-sheeter says 1–120 seconds for the Instagram placements and Facebook Stories, and 240 minutes for Facebook Feed. Both figures are shown above with their sources.
What file types does Meta accept?
MP4, MOV and GIF across the placements, except Instagram Reels, which lists MP4 and MOV only. The cap is 4 GB everywhere. Meta also asks that videos contain no edit lists or special boxes in the file container.
What is the Meta safe zone?
For 9:16 ads Meta asks you to leave roughly 14% of the top, 35% of the bottom and 6% of each side clear of text and logos — 269, 672 and 65 pixels on a 1080×1920 frame. The bottom margin becomes 40% if the ad carries a disclaimer. Meta publishes no safe zone for 4:5 or 1:1 feed placements.
Do these specs cover Facebook and Instagram both?
Yes — Meta publishes one spec set governing both, which is why they are on one page here rather than two. The placements differ from each other on duration and minimum frame size, not by which app they run in.
