Channel Art Specs
For optimal results on all devices Google recommends uploading a single 2560 px X 1224 px image that has been optimized to fit the below template:
How it works on Desktop
The below slice would be your desktop banner. It’s total dimensions are 2560 X 423 px.
New channels will have a flexible width on desktop, meaning that the site will scale to reveal more content on larger browser windows. There is a minimum size at which point the site would no longer adapt and a scroll bar would appear in the browser window. At the minimum width the channel art is 1546 X 423 px (this is the “Safe area” given that text & logos will not be cut off). At the maximum width, the channel art is 2560 X 423 px. This means that the “SAFE AREA” (channel art at minimum width) will always be visible and the areas to the right and left (shown with green arrows) might be visible depending on the viewer’s browser size.
How it works on Mobile
On mobile we will be using the safe area (red box in diagram above) scaled down to the width of the mobile screen (which varies by device).
How it works on Tablets
On tablets we will be using a slightly wider slice which is indicated by the pink box above. The aspect ratio of this slice is 1855 px by 423 px.
