Double spacing in Word takes three clicks

Open your document in Microsoft Word. Select all the text you want to double space — either the whole document by pressing Ctrl+A (or Cmd+A on Mac), or just highlight the paragraphs you want to change. Then go to the Home tab, find the Line Spacing button in the toolbar (it looks like horizontal lines with arrows), and click the dropdown to select 2.0.

That's the standard method. Word applies the change when ready to whatever text you selected. If you want double spacing to be the default for every new document you create, you can set it in your template instead — but most people just change it document by document as needed.

Key Takeaways

  • Select all text with Ctrl+A, then use the Line Spacing button on the Home tab to choose 2.0 spacing.
  • You can double space the entire document or just specific paragraphs by selecting only those paragraphs first.
  • Double spacing applies when ready and you can undo it with Ctrl+Z if you change your mind.
  • The Paragraph dialog box offers more spacing options if you need something other than standard double spacing.

Finding the Line Spacing button in different Word versions

In Word 2019, Word 2021, and Microsoft 365, the Line Spacing button sits in the Paragraph section of the Home tab. It's the icon with four horizontal lines and up-and-down arrows. Click the small arrow next to it to open the menu.

In older versions like Word 2010 or 2013, the button is in the same place but may look slightly different. If you can't find it, you can also right-click any selected text, choose Paragraph, and adjust spacing in the dialog box that opens — look for the Line spacing dropdown and select Double.

Using the Paragraph dialog for more control

The Line Spacing dropdown menu gives you preset options: Single, 1.5 lines, Double, Triple, and a few others. If you need something more specific — like 2.25 spacing or exactly 18 points — open the Paragraph dialog instead. Right-click your selected text and choose Paragraph, then click the Indents & Spacing tab.

In the Line spacing section, change the dropdown from Single to At least, Exactly, or Multiple depending on what you need. Then enter the number in the box next to it. This method gives you pixel-perfect control if your assignment or publication has unusual spacing requirements.

Changing spacing for part of a document

You don't have to double space the whole document. Click at the beginning of the section you want to change, then hold Shift and click at the end of that section. This highlights just that portion. Then explore double spacing the same way — through the Line Spacing button or the Paragraph dialog.

This is useful if you need to double space the body of an essay but keep the title or header at single spacing, or if you're working with a document that mixes different formatting requirements. Word treats each selection independently, so you can have multiple spacing levels in one file.

Undoing and checking your spacing

If you double space by mistake, press Ctrl+Z to undo. Word will revert to whatever spacing was there before. You can undo multiple times if you need to go back several steps.

To check what spacing is currently applied to a paragraph, click anywhere in that paragraph and look at the Line Spacing button. It will show the current setting. If you're not sure whether text is single or double spaced just by looking, the button tells you — or you can open the Paragraph dialog to see the exact measurement.

Why double spacing matters for different situations

Schools often require double spacing on essays and research papers because it gives teachers room to write comments between lines. Publishers and editors also use double spacing during the review process for the same reason. Some organizations require it for accessibility — the extra space makes text easier to read for people with certain vision conditions.

If you're submitting work to someone else, check their instructions first. They'll usually specify whether they want single, double, or 1.5 spacing. Following the exact requirement matters because it affects how many pages your document takes up, and some assignments have page limits.

Frequently Asked Questions

Does double spacing change the font size?

No. Double spacing only changes the vertical distance between lines of text. The font itself stays the same size. If your document looks too large or too small, that's a separate adjustment in the font size dropdown.

Can I make double spacing the default for all my new documents?

Yes, but it requires editing your template. In Word, go to File > Options > Advanced, scroll to Show document content, and check "Print layouts". Then open a blank document, set it to double spacing, and save it as your default template. Every new document will start with that spacing. Most people find it easier to just change spacing in each document as needed.

What if the Line Spacing button is grayed out?

This usually means you're in a view that doesn't allow editing, like Print Preview or Read Mode. Switch back to Edit mode by clicking the Edit Document button, or press Ctrl+Home to return to normal editing view. Then the button will be active again.

Does double spacing work the same way in Google Docs?

No. Google Docs uses a different menu. Select your text, go to Format > Line spacing, and choose Double. The process is similar but the buttons are in different places. If you're switching between Word and Google Docs, check the line spacing in each program separately.
