How to Double Space Each Line in Microsoft Word Easily

To double-space text in Word, select the text, then choose Home > Line and Paragraph Spacing > 2.0. To apply it to a whole document, click in the document body and press Ctrl+A on Windows or Command+A on Mac before choosing 2.0. Double spacing adds vertical room between lines of text; it does not insert blank lines or change the words themselves.

What You’ll Need

A document open in Microsoft Word for Microsoft 365 on Windows or Mac. The ribbon labels below apply to the current desktop versions; Word for the web has a similar Home tab, though the layout can vary.
Text to format. You can select a paragraph, several paragraphs, or the document body. If you want to format only part of a document, know where that selection begins and ends before changing the spacing.

You do not need to install an add-in or change a document-wide preference. The spacing setting is part of paragraph formatting and can be applied to existing text or used as you type.

Step-by-Step

Open the document and decide what should be double-spaced. If the requirement applies to everything in the main document, you can select the full body. If it applies only to a section, identify the first and last paragraph in that section. This matters because Word applies line spacing to paragraphs, and formatting the wrong selection can affect headings, captions, or other text you intended to leave unchanged.
Select the text or paragraphs. To select a portion, click before its first character, hold the mouse button, and drag through the last character. You can also click in a paragraph and triple-click in many Word layouts to select that paragraph, or use Shift with the arrow keys to extend a selection. On Windows, click in the document body and press Ctrl+A to select its contents; on Mac, press Command+A. If the cursor is in a table, header, footer, or text box, the selection may apply only to that area rather than the entire document.
Open the line-spacing menu. Select the Home tab on the ribbon. In the Paragraph group, choose Line and Paragraph Spacing. The control usually shows horizontal lines with up-and-down arrows. If the Word window is narrow, the ribbon may compress the Paragraph group; maximize the window or look for the spacing control within that group.
Choose 2.0. Click 2.0 in the menu. Word immediately applies double line spacing to the selected paragraphs. The lines within each paragraph should now have more vertical distance between them, making the text easier to read, mark up, or review.
Check the beginning and end of the selection. Scroll through the changed area and confirm the intended paragraphs have the new spacing. Look especially at a heading or paragraph just before and after the selection. If either changed by mistake, use Undo immediately or select only the paragraph that needs correction and apply the appropriate spacing.
Use the Paragraph dialog if you need a precise setting. With the text selected, open Home and click the small diagonal arrow in the bottom-right corner of the Paragraph group. In the Paragraph dialog, find the Spacing section, open the Line spacing list, choose Double, and select OK. This is useful when you also need to inspect spacing before or after paragraphs. The dialog method is available in desktop Word on Windows and Mac, though the dialog’s appearance can differ slightly.
Apply double spacing to text you type next. If the whole document is already selected, choosing 2.0 sets the selected paragraphs to double spacing; click at the end of the document and press Enter to continue in the following paragraph, then check that the spacing carries forward. Word generally carries paragraph formatting into a new paragraph, but a different style or a pasted section can override it. If new paragraphs revert, select them and apply 2.0, or adjust the style used for those paragraphs.
Save the document. Press Ctrl+S on Windows or Command+S on Mac. If the file will be reviewed or printed elsewhere, reopen it or use Print Preview to make sure the extra line spacing has not caused an unwanted page break or separated a heading from its text.

Keyboard shortcut: In desktop Word for Windows, Ctrl+2 applies double spacing to the selected paragraphs, or to the paragraph containing the insertion point if no text is selected. On Mac, Command+2 is the corresponding shortcut. The ribbon option is easier to verify if your keyboard layout, system settings, or another app intercepts the shortcut.

Common Mistakes

Adding empty paragraphs instead of changing line spacing. Pressing Enter between every line creates separate paragraphs. That can produce uneven gaps, complicate editing, and make the document longer than expected. Use the 2.0 line-spacing setting instead. Double spacing changes the vertical spacing of lines within a paragraph without adding extra paragraph marks.

Confusing line spacing with paragraph spacing. Line spacing controls the distance between lines within a paragraph. Before and After paragraph spacing adds space around whole paragraphs. If the document looks as if it has large blank gaps between paragraphs, open the Paragraph dialog and inspect both settings. A document can have double line spacing and also have extra space after each paragraph; those are separate controls.

Formatting only the current paragraph. Clicking 2.0 with no text selected usually changes the paragraph where the cursor sits, not every paragraph in the document. Select the full intended range first, or use the shortcut after selecting it. Check that the selection is highlighted before applying the setting.

Applying the setting to more than intended. Ctrl+A or Command+A is convenient, but may include text you did not mean to change if you are working in a text box or another document area. For a specific section, make a deliberate selection and review its boundaries before clicking 2.0.

Assuming every element is included. Main body text, headers, footers, footnotes, text boxes, and some table content can behave as separate areas. A full-document selection may not catch every one. If a particular element remains single-spaced, select its text directly and format it on its own.

Tips

Format paragraphs rather than individual lines. Word’s line-spacing setting belongs to paragraphs. If a paragraph wraps onto several visual lines, selecting part of it may still change the spacing for that paragraph. That is usually the right result: the wrapped lines should have the same spacing as the rest of the paragraph.

Use the style when the document follows a format requirement. If body paragraphs and headings need different spacing, do not automatically apply 2.0 to all text. Select the body paragraphs, or change the paragraph style used for body text. To adjust a style in desktop Word, right-click its name in the Styles gallery on the Home tab, choose Modify, and use Format > Paragraph to set Line spacing to Double. This helps keep paragraphs consistent, but check that the style is used only where the setting is wanted.

Keep paragraph spacing intentional. For a traditional double-spaced manuscript, paragraph spacing before and after may be expected to remain at zero, but follow the instructions for your assignment or workplace. If paragraphs appear too far apart, inspect the Before and After boxes in the Paragraph dialog rather than switching line spacing back to single.

Check page breaks after formatting. Double spacing uses more vertical space, so a document may gain pages or push a heading to the bottom of a page. Use Print Layout or Print Preview to review page flow. If a heading is stranded, use paragraph pagination settings or adjust the surrounding content instead of inserting repeated blank lines.

For Mac, use the ribbon if the shortcut is unfamiliar. The Home tab and Line and Paragraph Spacing menu provide the same basic choice in Word for Mac. Keyboard shortcuts can vary with keyboard layout and app settings, so choosing 2.0 from the menu is a dependable way to confirm the formatting.

Troubleshooting

The text still looks single-spaced. First confirm that the paragraph or range was selected when you chose 2.0. Open Home > Line and Paragraph Spacing again and check the selected paragraph’s setting. If the menu does not make the current value clear, open the Paragraph dialog and verify Line spacing is set to Double. Also check whether you changed text in a separate text box, table, header, or footnote instead of the body text you meant to format.

There is too much space between paragraphs. This is usually paragraph spacing, not a mistake in the 2.0 setting. Select the affected paragraphs, open the Paragraph dialog from Home, and review Spacing Before and After. Set those values to the required amounts. Avoid using Remove Space After Paragraph unless you have checked the document’s intended formatting, since that command changes paragraph spacing rather than the double-spacing choice itself.

Only some paragraphs changed. The selection may have ended early, or the unaffected text may be in a separate document area. Select the remaining paragraphs and apply 2.0. If formatting keeps varying, check whether those paragraphs use different styles. You can select the affected paragraphs together and apply the setting, or modify the relevant style if all paragraphs using it should match.

New text returns to single spacing. Check the style applied to the new paragraph in the Styles gallery. A pasted paragraph or a heading style may carry different formatting. Select the new text and choose 2.0, or modify the relevant style if that is appropriate for the entire document. When pasting text from another source, use Word’s paste options to keep text-only formatting if you do not want imported paragraph settings.

The document gained extra pages. That is expected when lines take more vertical room. Check Print Preview and page breaks, but do not reduce the spacing if a submission or template specifically requires double spacing. If the setting was accidental, select the affected paragraphs and choose the desired value, such as 1.0 or 1.5, from Line and Paragraph Spacing.

The menu or shortcut does not work. Click inside editable document text and try the Home tab menu. If the document is protected or opened read-only, Word may prevent formatting; check the title bar or the Review tab for protection controls and obtain editing access if needed. If the keyboard shortcut triggers another command, use the ribbon instead.

Frequently Asked Questions

Does double spacing mean inserting a blank line after every line?
No. It sets the distance between lines to double spacing. Inserting a blank paragraph with Enter is different and can create inconsistent gaps.

How do I double-space an entire Word document?
Click in the document body, press Ctrl+A on Windows or Command+A on Mac, then choose Home > Line and Paragraph Spacing > 2.0. Check separate areas such as headers or text boxes individually if they also need the setting.

Can I double-space just one paragraph?
Yes. Click in that paragraph and choose 2.0 from the Line and Paragraph Spacing menu. Because the setting applies to paragraphs, selecting only a few characters in a paragraph will generally affect the paragraph they belong to.

What is the shortcut for double spacing?
Use Ctrl+2 in Word for Windows or Command+2 in Word for Mac. Select multiple paragraphs first to change them together. If the shortcut does not work on your system, use the Home tab menu.

Why does 2.0 spacing look different in different documents?
Font size, font design, paragraph spacing, and page layout all affect how the result looks. The 2.0 setting controls line spacing, while Before and After settings control gaps around paragraphs. Compare those settings as well as the font when documents look different.

Can I make double spacing the default for new documents?
You can modify the Normal style or set a default in the Paragraph dialog, but doing so may affect future documents. If only one file needs double spacing, change that document’s paragraphs instead. For a shared template or required format, confirm the expected settings before changing a default.
