Pinterest has announced that it is making its max width video adverts available to all brands using the platform.
In a blog post discussing the rollout, Pinterest explained that trials of the larger-sized Promoted Video ads had helped to boost awareness and engagement for brands, with John Lewis, Adidas, Paramount Pictures, Warner Bros, Chevrolet and P&G all taking part.
John Lewis saw a 20 per cent increase in awareness and a 33 per cent rise in purchase intent after trying out the bigger ads for its range of nursery products.
Pinterest stated: "Bigger does mean better: we've seen increased engagement rates for this format as Pinners take notice of this high-impact video."
The social sharing platform explained that standard width videos are the same size as general Pins, but max width videos are four times bigger, spanning the entirety of the site's two-column grid format.
The blog from Pinterest also included some best practice video ad advice, with tips including that clips should ideally be between six and 20 seconds long to secure maximum engagement.
