Remember that they need to be the same font and font size as the rest of your paper. You can add automatic page numbers through the Insert menu, and then double-click the header to add your title on the left if needed. Google Docs lets you add headers to any page. If you're a student, you may only need the page number. Quick tip: If you're writing for a professional context, your header should include a title and page number on every page. Every page needs a header with the paper's title in the top-left, and the page number in the top-right.Highlight all the text in your document, then select Double in this menu to turn on double-spacing. Meanwhile, you can enable double-spacing with the Line & paragraph spacing menu in the toolbar above your document. If you want to double-check or change them anyway, you can change the margins using the Page Setup menu or ruler feature.
Your font and font size need to be readable.
