I want to use a new image for the background to a new site in SharePoint 2013. Essentially I want a solid colour to replace the image that the 'Change the look' section puts in place.

I can produce the image easily enough in MS Paint but what I need to know is - what size should the image be in order to cover the entire screen?

The exact size of the image does not matter. Every screen is different. But choosing the image for a background follow these rules I came up with:

  • Choose an image with at least 1024x768 px in size.
  • Try not to use background images in the first place, they rarely look good with SharePoint 2013 anyway.
  • Choose an image with no people or faces, text, etc, because the image can be cut out depending on the window size.
  • Patterned backgrounds work best since you don't care if something gets cutout and patterns don't produce too much noise.
  • Make the image as light as possible. It should be almost white. You should probably choose of opacity that is no higher than 20% or even 5-10%. Otherwise it will produce too much noise and will interfere with the text on the screen.
