Ad Creative Specifications

This is a guide to Creative Specifications for Feathr Ad Campaigns (Retargeting, Email List, Search Keyword, Lookalike, and Geofence Campaigns).

For tips and best practices around the content of your creatives, read Best Practices for Creatives.

File Size:
The maximum file size of each creative that can be uploaded to Feathr is 200MB (exceptions for Facebook campaigns, see below).

File Format: Feathr accepts .png, .jpg, .gif, and video files.

Web Banners

Universal Ad Package Compliant Sizes
The Universal Ad Package is a set of four web banner creative sizes that are accepted and available almost universally across the web. We highly recommend including these sizes in your Ad Campaign. The sizes are (in pixels, width x height):

• 300 x 250
• 728 x 90
• 160 x 600
• 180 x 150
• 125 x 125

IAB Rising Stars
The following creative sizes are gaining popularity across the web, and as they're less frequently available, they make an impression when they're seen. The sizes are (in pixels, width x height):

• 970 x 250
• 300 x 600
• 320 x 250
• 300 x 1050
• 970 x 90

Geofence Campaign sizes
Because Geofence campaigns (not Historical Geofence Campaigns*) target people on their mobile devices and tablets, you should only use creatives that will appear on those size devices. Although Geofencing campaigns have slightly different size requirements, the same file formats mentioned above are supported. The best Geofence creative sizes are listed below. Due to limitations in the Bannersnack engine Feathr uses in its creatives builder, Bannersnack creatives cannot be used directly in Geofencing campaigns. You can, however, download your Bannersnack creatives as .jpg or .png files and upload them into your Geofencing campaigns.

Geofencing sizes are (in pixels, width x height):

• 300 x 50
• 300 x 250
• 320 x 50
• 320 x 480
• 336 x 280

Note: Because they are mobile-only, Geofencing campaigns cannot support AdTag creatives. 

*Because Historical Geofence Campaigns retarget people after they have left the geofenced area, the creative sizes do not need to be optimized for mobile. The audience may be browsing from any device after they have left the geotargeted area, not only mobile devices.

Video Creatives

You can serve video creatives through Feathr that meet the following specifications: 

Facebook Campaign creatives

There are stricter content requirements on Facebook creatives than general display creatives. Be sure to familiarize yourself with those requirements before designing ads to use on Facebook, or you risk having your ads rejected during Facebook's review process. Text should comprise less than 20% of the total image area of the creative or video thumbnail. Facebook sizes are (in pixels, width x height):

Common Questions

Why isn't my creative uploading? 
You may be getting an error when uploading a creative if it's not a supported size. Be sure to double check the size of the ad to make sure it's one of the sizes mentioned above. If you are not seeing the window to upload creatives at all, disable pop-up blockers and refresh.

Where do I add my Facebook creatives?
If you're launching a Facebook campaign, make sure you've selected a Facebook Retargeting campaign, not a Retargeting campaign. Follow the steps for launching a Facebook campaign, and you will be directed to upload your Facebook sized creatives, just like you would in an Ad campaign. 

Can I use HTML5 ads?
The Feathr bannersnack editor can be used to create HTML5 banner ads directly in your account. You can also use Ad Tags instead of standard creatives, as long as they resolve to HTML5 ad tag creatives. While we can't accept the raw HTML5 assets that would be used to create such Ad Tags, tools like Google Web Designer and Creatopy can be used to import Ad Tags.
