How to Double Space in Word for Text or Full Document

To double-space text in Microsoft Word, select the text, then choose Home > Line and Paragraph Spacing > 2.0. To double-space the entire document, press Ctrl+A first on Windows or Command+A on Mac, then choose 2.0. You can also use Ctrl+2 on Windows or Command+2 on Mac. Double spacing adds more vertical room between lines; it does not change the font size or the amount of text.

The instructions below are for Word for Microsoft 365 on Windows, with Mac differences noted where useful. The same ribbon setting is available in many recent desktop versions of Word. If you are formatting a paper, manuscript, or work document, check whether its instructions also specify paragraph spacing, margins, or font settings: double spacing alone may not satisfy every requirement.

What You’ll Need

A document open in Microsoft Word. Save a copy first if you want to preserve the original formatting or compare versions.
The text you want to change, if you are not applying double spacing to the whole document. You can select a paragraph, several paragraphs, or all the main document text.
Access to Word’s Home tab or the keyboard. You do not need to install anything or change the font.

Step-by-Step

Open the document and decide what should be double-spaced. Double spacing can be applied to a single paragraph, a selected section, or the main body of the entire document. If only the essay text needs it, leave the title, bibliography, footnotes, or other special sections alone unless your instructions say otherwise. Making this decision first helps avoid changing parts that should keep their current layout.
Select the text you want to format. Click in a paragraph to change that paragraph without selecting text; paragraph formatting applies to the paragraph where the cursor is. To change a range, drag across the text or click at its start, hold Shift, and click at its end. To select the main document, click in its body and press Ctrl+A on Windows or Command+A on Mac. Check that the selection covers the intended text before continuing.
Open the line-spacing menu. On Windows, go to the Home tab. In the Paragraph group, click Line and Paragraph Spacing, usually shown as horizontal lines with up-and-down arrows. If the Word window is narrow, the button may be condensed or hidden in the Paragraph group; maximize the window or look for the group’s additional options. On Mac, use the Home tab and the corresponding Line and Paragraph Spacing control.
Choose 2.0. In the menu, click 2.0. Word applies double line spacing to the selected paragraphs. If no text was selected, the paragraph containing the cursor is changed. Look at more than one line and paragraph to confirm the setting took effect. The visible gap between lines should be clearly larger than single spacing, but it should not look like a blank line was inserted after every line.
Use the keyboard shortcut if you prefer. With the relevant text selected, press Ctrl+2 in Word for Windows or Command+2 in Word for Mac. The shortcut sets line spacing to double. It is different from pressing Enter twice: extra paragraph breaks create blank lines and can cause uneven spacing. If you use a laptop, the number 2 on the main keyboard is the simplest option; you do not need to use a numeric keypad.
Apply double spacing to the full document when needed. Click in the document body, press Ctrl+A or Command+A, and choose 2.0 from the line-spacing menu. Then scan the title, headings, lists, and final page. A whole-document selection may also affect text such as headings and lists, and that can change page breaks. If a portion should remain single-spaced, select just that portion afterward and choose 1.0, or format the main text in sections rather than changing everything at once.
Check the paragraph spacing and save. If the document has unusually large gaps between paragraphs, select the affected paragraphs and open Home > Line and Paragraph Spacing. Look for options such as Add Space Before Paragraph or Remove Space After Paragraph, which are separate from the 2.0 line-spacing setting. Do not remove paragraph spacing automatically if your layout or assignment instructions require it. When the page looks right, save with Ctrl+S on Windows or Command+S on Mac.

Alternative using the Paragraph dialog: Select the relevant paragraphs, then open the Paragraph dialog from the small dialog box launcher in the bottom-right corner of the Home tab’s Paragraph group. In the Indents and Spacing tab, find Line spacing, choose Double, and select OK. This is useful when you want to confirm the exact paragraph settings or adjust indentation and spacing at the same time. On Mac, you can also find paragraph settings through Format > Paragraph; the dialog labels may vary slightly with the Word version.

Common Mistakes

Pressing Enter twice between lines. This inserts extra paragraph breaks rather than changing line spacing. The result may look acceptable in one spot but will shift unpredictably when you edit the text. Use the 2.0 setting instead.
Changing only the current paragraph by accident. If the cursor is in one paragraph and nothing is selected, Word generally formats that paragraph only. Select the full passage or use Ctrl+A or Command+A if the complete document needs the change.
Confusing line spacing with paragraph spacing. Line spacing controls the distance between lines within a paragraph. Paragraph spacing adds room before or after a paragraph. A document can be double-spaced and still have extra paragraph gaps, so check both settings when the layout looks too loose.
Selecting everything without checking special sections. Ctrl+A or Command+A can change titles, lists, tables, and other content in the main document. That may be fine, but it can also make a cover page or references look different than intended. Review the full document after applying the setting.
Assuming the font or page layout has changed. Double spacing does not mean a larger font, wider margins, or a blank line after every sentence. If the document becomes longer, that is expected: more vertical space is being used between lines.

Tips

Use a shortcut for quick changes. Ctrl+2 on Windows and Command+2 on Mac are convenient for applying double spacing to selected paragraphs. Ctrl+1 or Command+1 returns the selection to single spacing, while Ctrl+5 or Command+5 applies 1.5 spacing in desktop Word. Make sure Word has focus before using a shortcut.
Use the Paragraph dialog for precise formatting. The dialog is helpful when an assignment calls for double line spacing but a specific amount of space before or after paragraphs. Set line spacing to Double, then set paragraph spacing separately according to the instructions. This prevents an accidental combination of double lines and large paragraph gaps.
Check the whole page, not just the selected passage. Double spacing can push a heading or the last few lines onto another page. Use Print Layout or print preview to check page breaks, widows, and short final pages before submitting or sharing the file.
Consider styles for a document you will keep editing. If most body paragraphs should be double-spaced, changing the Normal style can make the formatting consistent for existing or new paragraphs that use that style. In Word, right-click Normal in the Styles gallery, choose Modify, then use the formatting controls to set paragraph line spacing. Be aware that changing a style may also affect other text based on that style.
Keep a clean original when formatting important work. Save a copy before changing a long document, especially if it contains tables, section breaks, or carefully arranged headings. A separate formatted copy makes it easier to return to the original if the page count or layout changes more than expected.

Troubleshooting

Nothing changed: Confirm that you selected the text, or that the cursor is inside the paragraph you meant to format. Then reopen the spacing menu and click 2.0. If you used a shortcut, check that the document—not another window or a text-entry field—was active.

Only part of the document changed: The selection may not have included every paragraph. Click in the document body, select all with Ctrl+A or Command+A, and apply 2.0 again. If the file has separate text boxes, headers, or footers, those areas may need to be selected and formatted individually; selecting the main body does not always include them.

The gaps look much larger than double spacing: Extra space before or after paragraphs is probably being added in addition to line spacing. Select the affected paragraphs, open the Paragraph dialog, and review both Line spacing and the Before and After spacing fields. Adjust the latter only if your instructions allow it. Also check for accidental empty paragraphs by turning on formatting marks with Home > ¶; delete unnecessary paragraph marks rather than changing line spacing to compensate.

The layout changed or pages were added: This is normal when every line takes up more vertical room. Review the page breaks and headings, and adjust only other formatting that your requirements permit. If the result is difficult to undo, press Ctrl+Z on Windows or Command+Z on Mac immediately, then reselect the intended text and apply the setting more carefully. If you already made several unrelated edits, reopen the saved copy instead of repeatedly undoing changes.

The button is missing: The Word ribbon may be collapsed or simplified. Expand the ribbon, widen the window, or use the Paragraph dialog from the Home tab. In Word for the web, use the Home tab’s line-spacing control when available; the desktop keyboard shortcuts and dialog layout can differ by browser and version.

Frequently Asked Questions

How do I double-space just one paragraph in Word?

Click inside that paragraph and choose Home > Line and Paragraph Spacing > 2.0, or press Ctrl+2 on Windows or Command+2 on Mac. You do not need to select the paragraph when the cursor is inside it.

How do I double-space only part of a document?

Select the specific words or paragraphs, then choose 2.0 from the line-spacing menu. Word applies paragraph formatting to the paragraphs touched by the selection, so check the beginning and end of the range afterward.

Does double spacing add a blank line between paragraphs?

No. Double spacing increases the distance between lines within paragraphs. Space before or after paragraphs is a separate setting, and a blank line is a separate empty paragraph usually created by pressing Enter.

Can I double-space a document before typing?

Yes. Set the cursor in a blank paragraph and choose 2.0 before you start. New paragraphs may inherit that formatting. For a consistent document template, modify the Normal style or choose the appropriate paragraph style before writing.

Will double spacing change my page count?

Usually. The extra vertical space often moves text onto additional pages, although the exact change depends on the font, margins, paragraph spacing, and document length. Review page breaks after applying it.

Is the Word double-spacing shortcut the same on Mac?

No. Use Ctrl+2 on Windows and Command+2 on Mac. The ribbon method is also available on both platforms, though the exact menu placement can vary slightly between Word versions.
