What Are "Flexible" Ads?
The "Flexible" ad format is a responsive, non-expanding ad unit that will adapt to all devices and screen resolutions and is based on the IAB 'New Standard Ad Unit Portfolio.'
Flexible ads can have different sizes within its define size range, but must always maintain its aspect ratio (e.g. a 6:1 ad may be bigger on an iPhone 6 Plus and smaller on an iPhone 5, but its width and height will always remain in the ratio of 6:1).
Commonly used ad sizes, like 728x90 can be replaced by a flexible 8:1, or a 300x600 can by replaced by a flexible 1:2 and so on.
