Check your file

Pick a placement and enter a size, or drop a file. The drawing shows whether it fits, gets cropped, or sits with space around it.

Width × height (px)

Fits. 1:1 is within the 1:1 to 4:5 Meta lists for Facebook Feed, so the file shows whole.

Video file settings

Meta's Ads Guide lists MP4, MOV or GIF for most placements, and MP4 or MOV for Instagram Reels. It recommends H.264 compression, square pixels, a fixed frame rate, progressive scan and stereo AAC audio at 128 kbps or more, and says videos should not contain edit lists or special boxes in file containers.

Video length by placement

Facebook Feed and Marketplace accept 1 second to 241 minutes, Instagram Feed and Stories 1 second to 60 minutes, Facebook Stories 1 second to 3 minutes, Instagram Reels up to 15 minutes and Messenger Stories up to 60 seconds. Audience Network rewarded video runs 3 to 61 seconds. Files can be up to 4 GB in every placement.

Long videos in Stories

Facebook Stories plays video ads of 15 seconds or less in full and splits longer ones into separate cards. Instagram Stories plays videos under 16 seconds in full and may split longer ones.

Reels ad specs and Instagram story size cover the vertical placements. Once a video campaign runs, the CPM calculator and the CPA calculator show what it costs.
