How to Double Space in Word Desktop and Format Text

To double-space text in Word desktop, select the text, then choose Home > Line and Paragraph Spacing > 2.0. To apply it to the whole document, click in the document body and press Ctrl+A first on Windows, or Command+A on Mac. Double spacing adds more vertical room between lines, which can make a document easier to read, review, or mark up. You need Word for desktop and a document open; the steps below cover Microsoft 365 for Windows, with Mac differences noted where they matter.

What You’ll Need

A document open in the Word desktop app. The ribbon labels may look slightly different in older Word versions, but the line-spacing control is in the Paragraph area of the Home tab.
The text you want to change. You can select a few paragraphs, a section, or the whole document. If you want new documents to use double spacing automatically, see the optional default-setting step below.

Step-by-Step

Open the document and decide what to format. Double spacing can apply to selected paragraphs, the paragraph where your cursor sits, or most of the document at once. If you only need a particular passage double-spaced, locate it before selecting anything. If the requirement applies to the entire assignment, click in the main body of the document and select all its text. On Windows, press Ctrl+A; on Mac, press Command+A. In a document with headers, footers, footnotes, or text boxes, remember that these may be separate text areas and might need their own formatting.
Select the text or paragraphs. To select a passage, drag across it with the mouse, or click at its start, hold Shift, and click at its end. You can also use the keyboard: click at the start, then hold Shift while using the arrow keys. To change only one paragraph, click anywhere in it; Word applies paragraph formatting to that paragraph without requiring a selection. For several separate passages, select one passage, then hold Ctrl on Windows or Command on Mac while selecting additional text, if your Word version supports multiple selections.
Open the spacing menu on the Home tab. In the Windows ribbon, select Home, find the Paragraph group, and click Line and Paragraph Spacing. The button usually has horizontal lines and up-and-down arrows. On Mac, use Home > Line and Paragraph Spacing as well. If the ribbon is simplified or the window is narrow, the button may be tucked into a compact menu; widen the window or expand the ribbon to find the Paragraph controls.
Choose 2.0. In the spacing menu, click 2.0. Word applies double line spacing to the selected text or the paragraph containing the cursor. The page may become longer, and text may move onto additional pages; that is expected. The 2.0 option controls the distance between lines within a paragraph. It does not necessarily remove extra space before or after paragraphs, so the document can still have larger gaps between paragraphs.
Check the result and save. Look at a paragraph with several lines and confirm there is visibly more space between its lines. If only some paragraphs changed, select the missing paragraphs and apply 2.0 again. Save with Ctrl+S on Windows or Command+S on Mac. If the document has a formatting specification, check whether it also calls for a particular font, margin, or paragraph spacing; double spacing alone does not set those other requirements.
Optional: use the Paragraph dialog for a precise setting. Select the text, then open the paragraph settings. In Windows, go to Home, click the small dialog launcher at the lower-right corner of the Paragraph group, and use the Indents and Spacing tab. Set Line spacing to Double, then choose OK. On Mac, use Format > Paragraph and set the line-spacing option to Double. The dialog is useful when you also need to inspect spacing before or after paragraphs or when the ribbon menu does not show the expected choice.
Optional: make double spacing the starting point for new documents. If you want this setting to apply regularly, open the Paragraph dialog as described above and choose Set As Default, if that control is available in your Word version. Follow the prompt to apply the change to documents based on the Normal template, rather than only the current file. The wording of the prompt can vary by platform or version. This changes a default, so use it only if you want future documents to start with the new spacing. To change only the current document, do not set a template-wide default.

Common Mistakes

Adding blank lines instead of changing line spacing. Pressing Enter between every line creates separate paragraphs, not double-spaced lines. It can cause uneven gaps, make later editing awkward, and affect paragraph formatting. Select the text and choose 2.0 instead.

Changing spacing for only one paragraph by accident. If no text is selected, Word applies paragraph formatting to the paragraph containing the insertion point. This is useful for a single paragraph but not for an entire document. Select the full range first when you need a broader change, and scan the beginning and end of the document afterward.

Confusing line spacing with paragraph spacing. Double line spacing adds room between lines in the same paragraph. The settings called Before and After add space around whole paragraphs. A document with both double line spacing and a large After value may have unusually wide gaps after each paragraph. If the gaps look too large, inspect those paragraph settings rather than switching away from 2.0.

Formatting only the visible body text. Headers, footers, footnotes, endnotes, and text inside shapes or text boxes can be handled separately from the main document. If a formatting rule applies to those areas too, open each area and set its spacing there. Also check tables: text in table cells may need to be selected and formatted within the table.

Assuming the 2.0 menu item sets every layout requirement. Double spacing does not choose a font, font size, page margins, indentation, or line numbering. Follow the full instructions for your document and adjust each requirement separately.

Tips

Use a keyboard shortcut for speed. On Windows, select the text and press Ctrl+2 to apply double spacing. On Mac, use Command+2. If there is no selection, the shortcut affects the paragraph containing the cursor. The shortcut applies spacing; it does not type the number 2 into the document.
Use the other spacing shortcuts if you need to compare. Word for Windows uses Ctrl+1 for single spacing and Ctrl+5 for 1.5 spacing. Word for Mac uses Command+1 and Command+5. These shortcuts can help you check whether a setting is single, one-and-a-half, or double, but use 2.0 when the requirement specifically says double.
Keep the selection until you have checked the control. After applying spacing, clicking elsewhere may remove the highlight, but the formatting remains. If you are unsure what you changed, click back into a paragraph and inspect the spacing menu or open the Paragraph dialog.
Format the whole document in one action when appropriate. Selecting all text before choosing 2.0 is faster than changing paragraphs one by one. However, it can also affect headings, lists, and other selected text. If those parts should keep a different layout, select only the paragraphs that need double spacing.
Expect page breaks to move. Double spacing increases the amount of vertical space used, so page count and page breaks can change. Review the document after formatting, especially near headings, tables, and the final page. Avoid adding manual page breaks just to restore the old page count unless the document instructions require them.

Troubleshooting

The menu does not show 2.0. Confirm that you opened Line and Paragraph Spacing on the Home tab, not a font, zoom, or paragraph-border menu. If the ribbon is collapsed, expand it or widen the Word window. You can also open the Paragraph dialog and choose Double from the Line spacing list.

Some lines still look crowded. Check whether the text is in a table, text box, header, or another separate area that was not selected. Then select the affected paragraphs and apply 2.0 directly. If the lines are double-spaced but paragraphs have large or inconsistent gaps, open Paragraph settings and check the Before and After values. Those are separate from line spacing.

The document changes back after you type. A paragraph style may be applying its own formatting to new paragraphs. Click in the affected paragraph, apply double spacing, and check whether the style changes when you press Enter. For a consistent document, select the relevant paragraphs and apply the setting to all of them; if the style itself must control spacing, modify that style rather than repeatedly correcting individual paragraphs. Be cautious when changing a style because every paragraph using it may change.

Ctrl+2 or Command+2 does something unexpected. First confirm you are working in the Word desktop app and that the document area has focus. The Windows shortcut is Ctrl+2; the Mac shortcut is Command+2. If a shortcut is intercepted by another app, keyboard layout, or custom Word setting, use Home > Line and Paragraph Spacing > 2.0 instead.

The whole document did not change. Check whether you selected the document body before applying the setting. Click in the body and select all again, then apply 2.0. Content in headers, footers, notes, tables, or shapes may need separate selection. If the file is protected or read-only, Word may prevent formatting; check whether editing is restricted or whether you need an editable copy.

Frequently Asked Questions

Does double spacing mean pressing Enter twice?
No. Choose 2.0 line spacing. Pressing Enter twice creates an additional blank paragraph, which can make layout inconsistent and is not the same as double-spacing the lines of a paragraph.

How do I double-space the entire Word document?
Click in the main document body, select all with Ctrl+A on Windows or Command+A on Mac, then choose Home > Line and Paragraph Spacing > 2.0. Check separate areas such as headers and footnotes if they must also be double-spaced.

Can I double-space just one paragraph?
Yes. Click anywhere in that paragraph and choose 2.0 from the line-spacing menu, or press Ctrl+2 on Windows or Command+2 on Mac. You do not have to select the entire paragraph first.

Is 2.0 the same as double spacing?
Yes. In Word’s line-spacing menu, 2.0 is the double-spacing option. The Paragraph dialog may label the same choice Double.

Why is there still a big gap between paragraphs?
Line spacing and paragraph spacing are independent. Double spacing controls the distance between lines inside a paragraph; the Paragraph dialog’s Before and After settings control added space around paragraphs. Reduce those values if your instructions call for no extra paragraph gap.

Will double spacing change the number of pages?
Usually. The same text takes up more vertical space, so it may flow onto additional pages and move page breaks. The exact page count depends on font, margins, paragraph spacing, and other layout choices.
