How to Double Space in Word on a Laptop: Quick Steps

To double-space text in Word on a laptop, select the text, then choose Home > Line and Paragraph Spacing > 2.0. To format the entire document, press Ctrl+A on Windows or Command+A on a Mac first. You can also place the cursor in a paragraph and use Ctrl+2 on Windows or Command+2 on a Mac to apply double spacing quickly.

Double spacing adds more vertical room between lines, which can make a document easier to read, mark up, or revise. The steps below apply to the Word desktop app in Microsoft 365; the ribbon controls are similar in Word for the web, although keyboard shortcuts may depend on your browser and device.

What You’ll Need

A laptop with Microsoft Word open and the document you want to format.
For a saved file, editing permission. If the document opens in read-only mode, choose an editable copy or ask its owner for access first.
A keyboard is useful but not essential; you can use the ribbon with a trackpad or mouse.

Step-by-Step

Open the document and check that you can edit it. Start Word and open the file. If you see a Protected View bar or a message that editing is restricted, select Enable Editing only if you trust the file, or resolve the permission issue. In Word for the web, open the file in editing mode rather than viewing mode. Save a copy first if you need to preserve the original layout.
Choose what you want to double-space. To change the whole document, click in its text and press Ctrl+A on Windows or Command+A on Mac. In some Word views, pressing the shortcut again can select more content, so check that the document text is highlighted before proceeding. To format only a section, drag across that text, or click at the start of the section, hold Shift, and click at its end. To change one paragraph, click anywhere inside it without selecting the words.
Open the line-spacing menu. Select the Home tab on the ribbon. In the Paragraph group, select the Line and Paragraph Spacing button, usually shown as horizontal lines with up-and-down arrows. If the ribbon is collapsed, expand it or use the Search box at the top of Word to find line spacing. Avoid choosing a command that only adds space before or after a paragraph; that is a different setting.
Select 2.0. Choose 2.0 from the menu. Word applies double line spacing to the selected paragraphs. If you selected the entire document, the change should run throughout it; if you clicked in just one paragraph, only that paragraph should change. Review the page to confirm the lines have visibly more vertical separation.
Use the keyboard shortcut if you prefer. Select the relevant text, then press Ctrl+2 in Word for Windows. On a Mac, press Command+2. The shortcut changes line spacing to double; it does not insert an empty paragraph between every line. Ctrl+1 on Windows and Command+1 on Mac set single spacing, while Ctrl+5 and Command+5 set 1.5 spacing.
Use the Paragraph dialog when you need a precise setting. On Windows, go to Home and select the small dialog launcher in the lower-right corner of the Paragraph group. In the Paragraph dialog, open Indents and Spacing, find Line spacing, choose Double, and select OK. On Word for Mac, use Format > Paragraph, choose Double in the Line spacing control, and confirm. The dialog is useful if the ribbon menu is unavailable or you want to inspect paragraph spacing as well.
Save and check the result. Press Ctrl+S on Windows or Command+S on Mac. Scroll through the document and check headings, lists, tables, and the final page. If only part of the text changed, undo once with Ctrl+Z or Command+Z and repeat after making the correct selection. If the whole document changed but you wanted only a passage, undo and select that passage more carefully.

Word formats text in paragraphs, so a selection that touches only a few words can still change the line spacing of the paragraph containing those words. This is normal. A paragraph is the text ending when you press Enter; a line that wraps naturally at the edge of the page is not a separate paragraph.

Common Mistakes

Pressing Enter between every line. This creates extra paragraphs, not double line spacing. It can make editing awkward and lead to uneven gaps when text reflows. Use the 2.0 line-spacing command instead.
Changing paragraph spacing instead of line spacing. The menu includes options such as Add Space Before Paragraph or Add Space After Paragraph. Those add gaps around paragraphs and may make the page look loosely spaced without doubling the lines within each paragraph. Choose 2.0 or set Line spacing to Double in the Paragraph dialog.
Selecting only the visible words in a paragraph. Word applies paragraph formatting to whole paragraphs. A selection that starts or ends in the middle of a paragraph may affect that entire paragraph, even if only a few words are highlighted. Check the paragraph boundaries when formatting a specific passage.
Assuming all text must have the same spacing. A document can contain different styles and paragraph formats. A title, footnote, table cell, or list may not look like the main body text after a change. Inspect those areas rather than assuming the document-wide command has made every region look identical.
Confusing double spacing with a larger font. Double spacing adds vertical distance between lines; it does not increase the type size. If the letters themselves look larger, check the font size on the Home tab.
Formatting a protected or unselected document. If the command has no visible effect, confirm that editing is enabled and that the text you intended to change is selected. The insertion point alone changes the paragraph where it sits, not necessarily the whole file.

Tips

Use the ribbon when you want to see the choice. The Home menu makes it easy to compare single, 1.5, and double spacing. The shortcut is faster once you know it, but the ribbon is more helpful when checking what setting you are applying.
Format before you add more text. If the entire document should be double-spaced, select all existing text and apply 2.0 before continuing. New paragraphs typed at the end usually inherit the formatting of the paragraph before them, though a pasted section or a different style can bring different formatting with it.
Use styles for a document you will keep revising. If body paragraphs use the Normal style, changing that style can make the formatting more consistent than fixing separate sections one by one. In Word for Windows, right-click Normal in the Styles gallery and choose Modify; use Format > Paragraph in the dialog to set line spacing. On Mac, modify the style from the Styles pane or the style controls available in your Word version. Check the preview and save carefully, because changing a style can affect every paragraph that uses it.
Keep an untouched copy when formatting matters. If a school, workplace, or publisher supplied a template, save a separate version before changing spacing. A copy makes it simple to return to the original if the spacing change affects page breaks or a required layout.
Remember that page count can increase. Double-spaced text takes more vertical space, so headings and paragraphs may move to later pages. That is expected. If the page count matters, check it after formatting, but do not reduce spacing if the document instructions specifically require double spacing.

Troubleshooting

The lines still look single-spaced. First click inside a paragraph and reopen Home > Line and Paragraph Spacing to see the active setting. If the menu does not clearly indicate it, open the Paragraph dialog and check Line spacing. Make sure you chose Double rather than 1.0 or a paragraph-spacing option. Zooming in can also make the difference easier to see.

There is a large gap between paragraphs. Double line spacing and spacing before or after paragraphs are separate controls. Open the Paragraph dialog and review Spacing Before and After. If those values are adding unwanted gaps, adjust them to the values required for your document, often 0 pt, then keep Line spacing set to Double. Avoid changing them blindly if the template or assignment specifies paragraph gaps.

Only some paragraphs changed. The selection may not have included all the text, or the document may use different styles. Press Ctrl+A or Command+A while editing the document, verify that the text is selected, and apply 2.0 again. If a heading or table still differs, select that content directly and check its paragraph setting. In a document with multiple sections or complex formatting, inspect each section rather than relying on one selection.

New text returns to single spacing. The insertion point may be in a paragraph with another style, or pasted text may have brought its own formatting. Click in the paragraph that is wrong and apply 2.0 to it. If this keeps happening in ordinary body text, modify the style used for that text or paste using a destination-formatting option, then check that the spacing remains correct.

The shortcut does nothing. Make sure the Word document has focus rather than another app or a browser address bar. On Windows, use Ctrl+2; on Mac, use Command+2. Laptop keyboards may require holding the Fn key for certain number-row keys, depending on the device settings. If the shortcut conflicts with another program or does not work in Word for the web, use the ribbon menu instead.

Word will not let you change the spacing. Look for a Protected View notice, editing restrictions, or a read-only label. Enable editing only for a file you trust. For a shared document, check that you have permission to edit; otherwise, ask for access or save an allowed copy. If the document is part of a form or controlled template, its author may have locked some formatting.

Frequently Asked Questions

What is the shortcut to double-space in Word?
In Word for Windows, select the text and press Ctrl+2. On a Mac, select the text and press Command+2. With no selection, the shortcut changes the paragraph containing the insertion point.

How do I double-space the whole document?
Click in the document, press Ctrl+A on Windows or Command+A on Mac, and choose Home > Line and Paragraph Spacing > 2.0. Save the file and scan the pages to confirm that headings, lists, and other areas look right.

Can I double-space only one paragraph?
Yes. Click anywhere in the paragraph and choose 2.0 from the line-spacing menu. You generally do not need to select every word, because Word applies paragraph formatting to the paragraph containing the cursor.

Does double spacing add a blank line between paragraphs?
No. It increases the distance between lines within paragraphs. A blank line is a separate empty paragraph, while spacing before or after a paragraph is another independent setting.

Will double spacing change my font size or margins?
No. It changes vertical line spacing, not font size or page margins. It can increase the number of pages because the lines take up more room, but the font and margins stay as they were.

Can I double-space in Word for the web?
Yes. Select the text, open the Home tab, choose Line and Paragraph Spacing, and select 2.0. If the ribbon or shortcut behaves differently in your browser, use the visible menu and confirm that the file is in editing mode.
