Use the Delete Key
This method is easy and makes the most sense for the majority of situations. Whether the extra page is there due to unnecessary spaces or content you no longer want, removing it involves selecting the unwanted area.
Undo a Page Break
Creating a page break can make blank pages. You can remove a page break similar to how you’d remove an extra page, but you don’t have to worry so much about highlighting anything.
Adjust Line Spacing
Google Docs might be adding extra space after paragraphs. This is a setting that can apply to the entire document and that no amount of backspacing can fix. Here’s what to do if you have extra pages or blank spaces that you can’t seem to remove normally: The pages are now consolidated and the page break removed. If that doesn’t work, repeat these steps but select the first sentence after the blank space and change the Before value during step 3.
Change the Margins
Although less common, margins that are too big could be the reason for extra pages. Making the margins smaller gives you more room to write on each page, thus preventing unnecessary blank spaces.
