Instagram’s New Carousel Format Restriction on Boosting Full-Screen Images
Bad news for brands looking to make use of Instagram’s new variable image size carousels, with carousels that include full-screen size images not eligible for boosting. Instagram recently introduced a new option that allows users to upload carousel collections of different sized images, giving more flexibility in composing carousel posts. However, users have discovered that posts with full-screen aspect ratio images cannot be boosted, as shown in a recent example. While this seems to be the only restriction on the new carousel format at this stage, it could impact the use of carousels for promotions and the overall value of this update. More information is being sought from Instagram regarding this error message and whether the restriction applies to all carousels with full-size images.
