Rather than have a whole bunch of different sizes for each of our wallpapers, we have them broken down into the four most common aspect ratios for computers. It is important to get the right aspect ratio for your monitor so that the image won’t need to be stretched or warped to fit properly. To find out which aspect ratio you need, simply find out your screen resolution (which, on Windows machines, can be found on the Control Panel under Display) and find it on the list below.
