The Style Override
Google Docs uses Arial as its default font for the “Normal text” paragraph style. If you are working on a corporate document, a school paper, or a manuscript, you likely have a strict requirement to use a different font, such as Times New Roman or Calibri. While you can highlight the text and change the font manually, if you paste new text into the document, or if you press Enter to start a new paragraph after a heading, Google Docs might automatically change the font back to Arial. This constant reversion is incredibly frustrating and forces you to re-format your entire document before final submission.
Updating the Default Stylesheet
To ensure your preferred typography persists throughout the entire document and stop Google Docs from automatically changing the default font back to Arial, you must update the core ‘Normal text’ style definition.
First, you must create a template of perfect formatting. Type a single sentence into your document. Highlight that sentence. Using the top toolbar, manually change the font to your preferred choice (e.g., Times New Roman), set the correct font size (e.g., 12), and ensure the text color is black. Keep that perfectly formatted sentence highlighted. Now, click the Styles dropdown menu in the toolbar (it usually says “Normal text”). Hover your mouse over the Normal text option in the menu. A sub-menu will appear to the right. Click on Update ‘Normal text’ to match. Google Docs will immediately update its internal CSS for that specific document. Now, whenever you press Enter, clear formatting, or paste text without formatting, Docs will automatically use your new, custom default font instead of Arial.
