How to change line spacing in Microsoft Word

Line spacing is the vertical distance between lines of text in a document. In Microsoft Word, you can change it in seconds using the Home tab or the Paragraph dialog box. The quickest method is to select your text, then click the line spacing button in the ribbon and choose a preset option like 1.5 or double spacing. If you need a custom spacing value, the Paragraph dialog gives you exact control down to the point.

Word applies line spacing to the paragraph you're in, not to individual lines. This means if you want different spacing in different parts of your document, you'll need to select each section separately and adjust it. You can also set a default line spacing for all new documents you create.

Key Takeaways

  • Select the text you want to change, then use the line spacing button on the Home tab to pick from preset options like single, 1.5, or double spacing.
  • For custom spacing values, open the Paragraph dialog by pressing Ctrl+0 (zero) or clicking the small arrow next to the Paragraph section on the Home tab.
  • Line spacing applies to entire paragraphs, so you must select each section separately if you want different spacing in different parts of your document.
  • You can set a default line spacing for all future documents by changing the spacing in the Normal template.

Using the line spacing button on the Home tab

The fastest way to change line spacing is through the ribbon. Open your document and select the text you want to adjust. If you want to change the spacing for the whole document, press Ctrl+A to select all text.

On the Home tab, look for the line spacing icon — it looks like three horizontal lines with arrows pointing up and down. Click the small arrow next to it to open a dropdown menu. You'll see options like Single, 1.15 Lines, 1.5 Lines, Double, and a few others. Click the one you want, and Word applies it immediately to your selected text.

This method works for the most common spacing needs. If none of the preset options match what you need, use the Paragraph dialog instead.

Opening the Paragraph dialog for custom spacing

The Paragraph dialog box gives you precise control over line spacing. You can reach it in two ways: press Ctrl+0 (the zero key, not the letter O), or go to the Home tab, find the Paragraph section, and click the small arrow in the bottom right corner of that section.

Once the dialog opens, click the Indents & Spacing tab if it's not already selected. Look for the Line Spacing dropdown, which usually shows "Single" or whatever spacing is currently applied. Click the dropdown to see your options: Single, 1.15 Lines, 1.5 Lines, Double, At Least, Exactly, and Multiple.

Most of these are self-explanatory. "At Least" sets a minimum spacing but allows Word to increase it if a line contains large text or images. "Exactly" locks the spacing to a fixed value. "Multiple" lets you enter a number like 1.2 or 2.5 for custom ratios. After you choose an option, enter any value if required, then click OK.

Understanding the different spacing options

Single spacing is the default and uses the smallest space between lines. 1.15 Lines adds a small amount of extra space — this is often used in professional documents because it's slightly easier to read than single spacing without taking up much extra room. 1.5 Lines and Double spacing are common in academic writing and formal submissions.

At Least spacing sets a minimum height for each line. If you enter 0.3 inches, Word will never make lines closer than that, but it will spread them further apart if the text is large. Exactly spacing locks lines to a fixed distance — if you set it to 0.3 inches, every line will be exactly that far from the next, which can cause large text to overlap. Use this only when you need precise control and understand the risk.

Multiple spacing lets you enter a decimal number. Entering 1.5 is the same as choosing 1.5 Lines; entering 2 is the same as double spacing. This option is useful if you need something like 1.25 spacing, which you can't get from the preset options.

Changing spacing for the whole document at once

To change line spacing throughout your entire document, press Ctrl+A to select all text, then use either the line spacing button or the Paragraph dialog to apply your choice. This is faster than selecting sections one at a time.

If you want to set a default line spacing for all new documents you create going forward, you'll need to modify the Normal template. Go to File, then Options, then Display. Look for the option related to default formatting or styles — the exact location varies by Word version. Alternatively, you can create a custom template with your preferred spacing and use that as your starting point for new documents.

Why line spacing matters in different contexts

Academic papers, particularly those submitted to universities, often require double spacing because it leaves room for handwritten comments and feedback. Professional business documents typically use single or 1.15 spacing to save paper and look more polished. Online documents and web content often benefit from 1.5 spacing because it's easier to read on screens.

If you're writing for a specific audience or following a style guide, check the requirements before you finalize your spacing. Many institutions and publications have specific rules about line spacing, font, and margins. Changing spacing after you've written your document is simple, so you can always adjust it later if needed.

Frequently Asked Questions

Does line spacing affect how many pages my document uses?

Yes. Double spacing uses roughly twice as much vertical space as single spacing, so a document with double spacing will be longer. If you're trying to fit content into a specific page count, changing line spacing is one way to adjust the length without cutting text.

Can I have different line spacing in different parts of the same document?

Yes. Select each section separately and apply different spacing to each one. You can also insert section breaks if you want to keep spacing changes organized, though it's not required.

What's the difference between line spacing and paragraph spacing?

Line spacing is the distance between lines within a paragraph. Paragraph spacing is the distance between one paragraph and the next. Both are adjustable in the Paragraph dialog — paragraph spacing appears as "Before" and "After" options above the line spacing dropdown.

Why does my text look different after I change line spacing?

Larger line spacing makes text easier to read but takes up more room on the page. Smaller spacing is more compact but can feel cramped. The visual difference is normal and expected — you're just adjusting how much air is between the lines.

Will changing line spacing affect my document when I share it with someone else?

No. When you send a Word document to someone else, the line spacing you set stays with the document. They'll see the same spacing you do, unless they open it in a different program that handles spacing differently.
