Template(s)

Using the file below is most suited for design layouts that are 100% bespoke and require highly customized animation. If a designer is new to our products, we recommend reviewing our Ad Framework Guide in order to get a deep dive into the anatomy of a GumGum ad.

Additional Details

For responsive unit types, please supply the order in which elements should drop off for smaller ad sizes
Ad Functionality
- Desktop unit is hover to expand
- Mobile unit is swipe to expand
The creative is always built at 2x scale for Retina Display
- One element can be up to 200px high collapsed and 400px high expanded (mockups) or 100px high collapsed and 200px high expanded (rendered)
- Tile height is 120px high collapsed and less than 400px high expanded (mockups) or 60px high collapsed and less than 200px high expanded (rendered)
Designers can utilize space on either side of the 600px "main content area" to add ornamentation.
- Up to 180px on either side of the 600px space can have additional design elements, flourishes, etc. Refer to Ad Framework Guide for more information and tips.
- Cannot be anything that is vital to the ad - no messaging, logos, etc because as the unit width shrinks these elements will start to be partially cropped out.
