Hi, If you use the "Full Width" layout, then your footer will be automatically Full Width. The layout of the page can be changed in Theme Options > Global > General http://prntscr.com/ltfj8u
If you want to have your content wider, then you have to increase your Grid Width to the higher value. It's inside the Theme Options > Global > General https://i.imgur.com/T40aOtw.png
