They are all the same size and it depends on what device you are using to view the wall. But the image we start with is 1280 x 720 pixels (16:9 aspect ratio). The wall space image you see is smaller but if you click through to an Expanded Wall Space (signified by a red GW circle), you will see the larger image (and other images as well along with additional content and outbound links). Standard Wall Spaces click directly through to their respective websites.
