Google Docs can prevent a single line of a paragraph from sitting alone at the top or bottom of a page. Use Prevent single lines when a report’s pagination creates these isolated fragments.
Enable the targeted layout control
- Open the document in Pages format on a computer.
- Select the paragraph or paragraphs to adjust.
- Choose Format > Line & paragraph spacing.
- Enable Prevent single lines.
The rule allows Google Docs to rebalance lines around a page boundary. It does not require keeping the entire paragraph on one page, so it can suit ordinary body text better than a keep-all-lines-together setting.
Separate three common requirements
Prevent single lines addresses an isolated opening or closing line. Keep lines together addresses a whole paragraph. Keep with next attaches a paragraph, often a heading, to its successor. Choose according to the specific defect you see.
Adding a manual line break or deleting a few words solely to fix one page can make the problem recur after the next edit. A paragraph rule is generally easier to maintain when text is still changing.
Review the final pagination
Inspect the page boundary where the problem occurred and the next boundary after it. Small adjustments can move content farther through a report. Check that the result still meets any submission requirements for page length, margins, and spacing.
If the option is unavailable, confirm that the document uses Pages rather than Pageless. Also check that the cursor is in ordinary document text and that you can edit the file. The purpose is readable printed pagination; it does not guarantee that every screen or exported format will reproduce identical line endings.
