There have been new ad formats spotted on Facebook’s news feed with larger images. The dimensions of the new ad format are 308 pixels x 308 pixels. The previous image size was 100 pixels x 72 pixels, which allows the new ad formats to stand out on a Facebook user’s news feed versus the old format.
In addition, Facebook users are able to Like, Comment and Share the suggested post, which may increase the ad’s visibility on the social network to additional users.
It looks like the new ad format size is being rolled out in selected accounts and is not yet available to all advertisers.
Below is a screen shot of the larger ad format in the Facebook news feed.
