Widows, orphans and “Keep with next”: no heading left alone at the bottom of a page
Select the paragraph and open Home › Paragraph (the small arrow in the group) › Line and Page Breaks tab. Check “Keep with next” so a heading travels with its text, “Keep lines together” so a paragraph never splits, and “Widow/Orphan control” so no single lines are left behind. The best place to set this is in your heading styles.
You spot it during the final read-through: a heading sits alone on the last line of a page while its text starts on the next one. Or the last line of a paragraph turns up by itself at the top of a new page. Or “Sec.” ends one line and the “5” starts the next. You fix it with an extra Enter… and as soon as you add a sentence above, everything shifts again.
Word has pagination rules for exactly this. Think of them as invisible strings: one ties a heading to the paragraph that follows it, another holds the lines of a paragraph together, another joins two words so they never split. The strings travel with the text, so the document rearranges itself no matter how much you edit.
In this guide you set them once, in your styles, and forget about them.

Step by step
Recognize the three pagination problems
An orphan is the first line of a paragraph left alone at the bottom of a page. A widow is the last line of a paragraph pushed alone onto the next page. And a stranded heading sits at the end of one page while its text starts on the next.
All three are fixed with paragraph options, not with Enter. An extra Enter works today and breaks the layout tomorrow, when the text moves.
Open Paragraph › Line and Page Breaks
Put the cursor in the paragraph (or select several). In Home › Paragraph, click the tiny arrow in the bottom-right corner of the group (the dialog box launcher). Right-clicking the text › Paragraph… works too.
In the Paragraph window, go to the second tab: Line and Page Breaks.
The same arrow appears under Layout › Paragraph and opens exactly the same window.
Understand the four pagination options
Under Pagination you'll find four check boxes:
- Widow/Orphan control: never leaves a single line of a paragraph at the bottom or top of a page. It's on in Normal; leave it that way.
- Keep with next: this paragraph always stays on the same page as the next one. This is the cure for stranded headings.
- Keep lines together: the paragraph never splits across pages; if it doesn't fit, it moves to the next page whole.
- Page break before: the paragraph always starts on a new page.
Set it in your heading styles, not paragraph by paragraph
Go to Home › Styles, right-click Heading 1 › Modify…. At the bottom left click Format › Paragraph… and, on Line and Page Breaks, check Keep with next and Keep lines together. Click OK twice.
Word's built-in headings already come with both boxes checked. But if you use your own styles (Clause, Article, Section Title) or an inherited document, check them: that's usually where the problem hides.
Select “New documents based on this template” in Modify Style so the change reaches every future document.
Make every chapter start on a new page
If every chapter or exhibit must open a page, don't insert manual page breaks. Modify the Heading 1 style as in the previous step and check Page break before. That way, if you delete or move a chapter, the others still start at the top.
If you also need different headers, margins or orientation per chapter, what you need is a section break: see section breaks.
Check where pagination rules are applied
Turn on formatting marks with Ctrl+Shift+8 (or the ¶ button in Home › Paragraph). Next to every paragraph with one of these options, a small black square appears in the left margin. It doesn't print: it's just a marker.
If you see that square on body text paragraphs, someone applied “Keep with next” by mistake, and that's why big gaps appear at the bottom of pages.
Join “Sec. 5”, “10 %” and names with a nonbreaking space
A nonbreaking space looks like a normal space, but Word never breaks a line there. Use it between “Sec.” and “5”, between “10” and “%”, between “J.” and a surname, or between a number and its unit (“25 kg”). Type it with Ctrl+Shift+Spacebar. With formatting marks on, it shows as a small circle (°) instead of the dot of a regular space.
For hyphenated words that must not split (“Mary-Kate”, a case number), use a nonbreaking hyphen: Ctrl+Shift+-, or Insert › Symbols › Symbol › More Symbols › Special Characters, which also lists the shortcut for each character.
Text pasted from an AI tool or a website usually loses its nonbreaking spaces. Find them and put them back in legal citations and figures before you send the document.
Expert tips
- Tie the signature to the last clause. In a contract, apply “Keep with next” to the final paragraph and to the signature lines (except the last one). The signature block will never end up alone on an empty page.
- Keep a short table on one page. Select all its rows except the last and apply “Keep with next”: Word moves the whole table to the next page if it doesn't fit.
- Find and restore special spaces. In Find and Replace,
^sfinds nonbreaking spaces. You can replace “Sec. ” with “Sec.^s” across the whole document in one go: see advanced find and replace. - Let the AI draft, you handle pagination. ChatGPT or Copilot can't control where pages fall. Apply heading styles and the rules in this guide take care of the rest.
Common mistakes and how to fix them
Huge gaps appear at the bottom of several pages.
Too many consecutive paragraphs have “Keep with next” or “Keep lines together”, so Word moves a giant block. Turn on formatting marks, find the black squares on body text paragraphs and clear those boxes.
You fixed stranded headings with Enter and editing scrambled everything.
Delete those empty paragraphs (or manual page breaks) and use “Keep with next” or “Page break before” in the heading style instead.
You checked the option on one heading, but the others are still stranded.
You formatted a single paragraph. Do it in the style (right-click › Modify › Format › Paragraph) so it applies to every heading at that level.
In Word for Mac the window is the same: Format menu › Paragraph… › Line and Page Breaks tab. A nonbreaking space is Option+Spacebar, and special characters are under Insert › Advanced Symbol.
Frequently asked questions
Why does Word sometimes leave a gap at the end of a page when I haven't inserted a break?
It's almost always a pagination rule at work: a heading with “Keep with next” or a paragraph with “Keep lines together” that didn't fit and moved to the next page whole. That's the correct behavior.
Is “Page break before” better than a manual page break?
For chapters, use “Page break before” in the style: it travels with the heading and doesn't leave blank pages when you reorganize. A manual break (Ctrl+Enter) is for one-off cases.
Does a nonbreaking space change how the text looks?
No. It prints exactly like a regular space. The only difference is that Word never breaks the line there. In justified text, its width may not stretch the way regular spaces do.
Can I turn off widow/orphan control?
Yes, by clearing the box in the Normal style. It only makes sense in documents where every page must have exactly the same number of lines, such as some pleadings on numbered paper.
