While Responsive Display Ads are primarily a visual media type, they do include copy elements, so we’ve included the full creative specs below. If you’re looking for a complete list of display ad specifications by channel, we’ve got you covered there too.
Logo File Size: 5120 kb
Logo Sizes:
Square (1:1) and larger than 128 x 128. The recommended size is 1200 x 1200.
Landscape (4:1) and larger than 512 x 128. The recommended size is 1200 x 300.
Logos should be centered and on a transparent background.
Image ratio: 1:1
Image File Type: .jpg or .png
Image File Size: 5120 kb
Image Sizes: larger than 300 x 300
Image ratio: 1.9:1
Image File Type: .jpg or .png
Image File Size: 5120 kb
Image Sizes: larger than 600×314
Note that like Facebook Ads, text can cover no more than 20% of the images, and some images may be cropped up to 5% horizontally on either side, so you should avoid text altogether whenever possible.
Same as YouTube parameters above. Responsive display ads require YouTube videos of less than 30 seconds to be eligible to run.
Short Headlines: Up to 5 headlines, 30 characters max per headline.
Long Headlines: 1 headline, 90 characters max.
Descriptions: Up to 5 descriptions, 90 characters max per description
These ads also require you to include your business name, final URL, and provide an option for including call to action text.
Just like responsive display ads, Discovery Ads are primarily a visual medium, but they do contain copy elements, so we’ve included them here to be thorough.
Logo File Size: 5120 kb
Logo Sizes:
Square (1:1) and larger than 128 x 128. The recommended size is 1200 x 1200.
Landscape (4:1) and larger than 512 x 128. The recommended size is 1200 x 300.
Logos should be centered and on a transparent background.
File Type: .jpg or .png
Image File Size: No stated limit
Images in Discovery Ads are different than any other image ad Google–or its competitors–has rolled out. There are far fewer limitations on image type or size, and the limitations are primarily on image quality.
Headlines: Up to 5 headlines, 40 characters max per headline.
Descriptions: Up to 5 descriptions, 90 characters max per description
These ads also require you to include your business name, final URL, and provide an option for including call to action text.
The parameters for Discovery Carousel Ads are the same as standard Discovery Ads, with the only exceptions being that only one headline and description line are available, and a minimum of two images (not counting the logo) are required instead of just one.
