What are the Instagram video length and Reel rules?

Instagram videos must be between 3 seconds and 15 minutes, and every video publishes as a Reel, a Story or a Trial Reel. Instagram no longer has a separate feed video type.

Video rules#

	Rule
Length	3 seconds to 15 minutes
Format	MP4 or MOV, H.264 or HEVC, up to 500 MB
Frame rate	23 to 60 fps
Aspect ratio	Reels and Stories: vertical 9:16.
Size	At least 150 x 150, at most 1920 x 1920
Count	1 video per post. No mixing with images

Post types for video#

• Reels: the default for a video. Appears in your feed and the Reels tab.
• Story: one video, gone after 24 hours.
• Trial Reel: shown to non-followers first. Instagram promotes it to your followers if it does well.

Choose the type under Post Type in the Instagram card of the post editor.

Image rules#

Feed images can be 4:5, 1:1 or 1.91:1, JPG or PNG, 320 x 320 up to 8192 x 8192, and up to 30 MB. Up to 10 images make a carousel. A Story takes one image or one video, no carousel.

Why did my video fail?#

• Over 15 minutes: the editor stops it before scheduling. Trim the video.
• Landscape or square Reel: Instagram may crop it or refuse it. Export 9:16.
• Still processing on Instagram: Instagram processes the video after upload. PostEverywhere waits for it, so a Reel can take a few minutes to appear.
• Account checkpoint: see Instagram checkpoint.
