What is the primary distinguishing feature of Max-width video ads on Pinterest?

Max-width video ads are a high-impact, mobile-only ad format on Pinterest. Their primary distinguishing feature is their size: Size and Placement: Unlike standard-width video ads, which take up a single column (the same size as a regular Pin), max-width videos span the entire two-column grid on a user's mobile feed. Visual Impact: Because they occupy significantly more screen space (often described as being ~4x larger than a standard Pin in terms of grid area), they are designed to grab attention and increase brand awareness by dominating the visual experience. Aspect Ratio: These ads typically use a 1:1 (square) or 16:9 (widescreen) aspect ratio. They cannot exceed the height of a 1:1 ratio, ensuring they stretch horizontally across the feed rather than vertically like standard Pins. Engagement: Pinterest tests have shown that this format drives higher brand recall and purchase intent simply because the content is harder to miss while scrolling.
