Pinterest max width video ad specs
Pinterest max-width video ads span the width of the feed instead of one column. Pinterest says they cannot exceed the height of a 1:1 ratio, so square or horizontal works. Files are .mp4, .mov or .m4v up to 2 GB, 4 seconds to 15 minutes, with a 100-character title of which the first 40 may show.

When the wider format is worth it
Max-width video takes more of the screen than a standard Pin, which suits launches, seasonal campaigns and anything where reach matters more than click cost. The catch is the ratio: the tall vertical cuts made for Reels or TikTok do not qualify, because nothing taller than square is allowed.
That means a dedicated square or horizontal edit. Compose for the centre of the frame and keep text large, because the video will often be watched at feed scale without sound.
Questions
- Can I use a vertical video for a Pinterest max width ad?
