Pinterest is more forgiving about video shape than TikTok or Reels, but the wrong ratio still gets your Pin cropped or shown small in the feed. Below are the specs Pinterest publishes for organic video Pins and for video ads, checked against Pinterest Help in October 2026.

Pinterest Video Specs at a Glance

  • Best size: 1080×1920 pixels (9:16, vertical, full-screen).
  • Other supported ratios: 1:2, 2:3, 3:4, 4:5 and 1:1.
  • Length (organic Pins): 4 seconds to 5 minutes.
  • File type: .MP4 or .M4V on the web; .MP4, .MOV or .M4V in the iPhone and Android apps.
  • Encoding: H.264 or H.265.

Best Aspect Ratio for Pinterest Video

Use 9:16 vertical whenever you can. It fills the screen when someone opens the Pin, and it is the same shape as TikTok, Reels and Shorts, so one export works everywhere. Pinterest also accepts 2:3 and 4:5, which take up a little less room in the feed, and square 1:1. Avoid horizontal 16:9 for organic Pins: it shows as a thin strip in a vertical feed.

Video Length: Organic Pins vs Ads

Organic video Pins must be between 4 seconds and 5 minutes. Video ads allow 4 seconds to 15 minutes, though Pinterest recommends 6 to 15 seconds for ads. Shorter usually works better for organic Pins too: most people decide in the first two seconds whether to keep watching.

Video Ad Specs

  • File type: .MP4, .MOV or .M4V.
  • Max file size: 2GB.
  • Length: 4 seconds to 15 minutes (6–15 seconds recommended).
  • Aspect ratio: narrower than 1.91:1 and wider than 1:2. Square (1:1) or vertical (2:3, 4:5, 9:16) is recommended.
  • Encoding: H.264 or H.265.
  • Max-width video ads: a paid-only format that spans two columns; the video can't be taller than 1:1.

Pinterest doesn't list a maximum file size for organic video Pins. If an upload fails, export at 1080×1920 with H.264, which keeps the file a sensible size without visible quality loss.

Reusing TikTok, Reels and Shorts Videos on Pinterest

Because Pinterest's preferred shape is 9:16, a vertical video made for TikTok, Instagram Reels or YouTube Shorts fits without re-editing. Use your clean original, or download a watermark-free copy of your own post, and check it is under 5 minutes. Our guide to repurposing one video for TikTok, Reels and Shorts covers captions and safe zones.

Saving Pinterest Videos You Find
