The ScrollX is a responsive format and the creative adapts seamlessly in devices with a small screen to large screen.

What you'll need to build a ScrollX

Here are the sizes of the different devices that support the format.

Mobile - 320(w) x 480(h) pixels
Desktop - 1024(w) x 768(h) pixels
Tablet - 768(w) x 960(h) pixels

It is good to consider the center of the canvas as the safe area leaving 20 pixels from all sides. This will enable you to keep your ad content from being cut off by device screen resolution.  

The rendered creative appears with a top and bottom bar. You can customize the text and color of the bars from the Studio canvas.
