Is it possible to upload a carousel with different sizes for each image, such as a 1x1 size and a 9x16 variation?
What would I name the files to have them upload correctly?
You can customize asset placement for carousel ads using the Ad Format called PAC Carousel.
How to use it
Open a Launch Sheet
Click on the Ad Format dropdown and select
PAC Carousel.Upload your assets in two sets:
First, the default assets (e.g., 1x1 for each card).
Then, the secondary assets (e.g., 9x16 for each card).
👉 Example: If you’re creating a 4-card carousel, upload 8 assets total (4 main + 4 vertical).
Add the rest information needed and launch the ad.
