How to read the table
Each figure carries the word Meta uses for it. A recommended size is what Meta suggests for the sharpest result. A minimum or maximum is a limit the upload has to meet, and a range is the span Meta accepts. Character counts are recommendations: Meta lists them under text recommendations, not as limits.
For one format in more detail, see Instagram story size, Facebook ad size, Reels ad specs, video ad specs and character limits.
One ad, several shapes
Meta's Ads Guide recommends 4:5 for Facebook and Instagram Feed images and 9:16 for Stories and Reels, the shape that fills a phone held upright. When an ad runs in several placements, Ads Manager adjusts the media to fit more of them; uploading a file in each placement's own shape gives more control over how it appears.
After the ad runs
Specs decide whether an ad shows as designed, not whether it works. Once it runs, the CTR calculator shows how often people click, the CPM calculator what a thousand impressions cost, and the ROAS calculator what the spend brought back.
Questions
Meta's Ads Guide recommends 1440 × 1800 pixels at 4:5 for Facebook and Instagram Feed images, and 1440 × 2560 at 9:16 for Stories and Reels. Images can be up to 30 MB.
4 GB. Meta's Help Center states a maximum file size of 4 GB for all videos, and every placement page in the Ads Guide lists the same limit.
No. The Ads Guide lists primary text, headline and description counts under text recommendations. They are the lengths Meta recommends for each placement.
Meta's guidance is to leave roughly 14% at the top, 35% at the bottom and 6% on each side of a 9:16 asset free of text, logos and other key elements, so the profile icon and the call to action do not cover them.
Yes. Meta's placement list on 3 November 2026 includes Audience Network native, banner and interstitial, and Audience Network rewarded videos.
