To adjust your essay, click on the page layout tab, displayed on the top panel. Then click the margins icon and choose the "Normal" option to establish proper margins.
Write your college essay. Disregard which spacing you should implement when initially writing your draft. After you have finished revising your essay, you will be able to tweak the spacing between lines for your final draft.
Click on the line spacing icon on the top panel of your document, in order to change the spacing in your text. You want to click on the 2.0 option, to double-space your college essay. This ensures easier reading and understanding.
Review the spacing between the words in your essay. A single space is needed after every word in your document. This also includes a space after punctuation marks such as commas, periods, colons and semi colons.
