Section Breaks, Part 4
Microsoft Word requires a section break when there is a change to page margins, orientation (portrait or landscape) or size, to footer contents or header contents.
How to set paper size
Go to the Insert tab, Page Layout group and select the dialog box launcher at the bottom-right of the group.
The Page Setup dialog box pops up, showing three tabs. Select the Paper tab (the middle one).
The default paper size when you buy a PC or laptop is “Letter”, used in the US. South Africans should change this to “A4”, as shown below.
