How to Double Space in Word for the Web

To double-space text in Word for the web, select the text, open Home > Line and Paragraph Spacing, and choose 2.0. To format the whole document, click in the document, select all its text, then choose 2.0. Double spacing adds more vertical room between lines, which can make a document easier to read or meet a formatting requirement.

What You’ll Need

A web browser and access to Word for the web at Microsoft 365.
A document you can edit. If it opens in read-only mode, switch to editing in the browser or make an editable copy first.
Text in the document, or a place to start typing. You do not need to install anything.

Step-by-Step

Open the document in editing mode. Sign in to Microsoft 365, open Word, and select the document. If you are viewing a file without editing controls, look for an option to edit it in the browser. Confirm that the ribbon is visible and that you can place the insertion point in the document. If you are creating a new document, open a blank document and add text, or set the spacing before you begin.
Decide what should be double-spaced. To format only part of the document, drag across the text you want to change. You can also click at the start of a section, hold Shift, and click at its end. To format the entire document, click inside the document body and press Ctrl+A on Windows. On a Mac, press Command+A. Make sure the selection covers the document text and not just a word or paragraph. If the document is long, check that the selected text extends through the sections you intend to change.
Open the spacing menu on the Home tab. With the text selected, choose Home on the ribbon. Find Line and Paragraph Spacing in the paragraph formatting controls. The button may appear as horizontal lines with up-and-down arrows. Select it to open the spacing menu. If the ribbon is narrow, some controls may be grouped or shown in a compact layout; widen the browser window or open the relevant ribbon menu to find the spacing control.
Choose 2.0. In the menu, select 2.0. Word applies double line spacing to the selected text or paragraphs. The text will take up more vertical space, so headings and paragraphs may move onto later pages. This is expected and does not mean the text has been duplicated. The other choices, such as 1.0 or 1.5, set different line spacing; for true double spacing, choose 2.0 rather than adding blank lines manually.
Check the result. Click elsewhere in the document to clear the selection and inspect a few paragraphs. Look at lines within a paragraph, not only the gap between paragraphs. Double spacing should create extra room between each line of a paragraph. Scroll through the document to confirm the change reached the full intended selection, especially if you selected only a section or used a long-document selection.
Continue editing and confirm it is saved. Word for the web normally saves changes to your Microsoft 365 document automatically. Wait for the save status to settle before closing the tab, and check that you are working in the correct file. To apply double spacing to new text, place the cursor in a double-spaced paragraph and continue typing; Word commonly carries that paragraph formatting forward. Check the next paragraph after pressing Enter, because its formatting can depend on the paragraph you started from and the document’s styles.

Common Mistakes

Selecting only the cursor position. If you click in a paragraph and choose 2.0 without selecting multiple paragraphs, Word may change the paragraph where the cursor is, rather than the whole document. For a document-wide change, click in the body and use Ctrl+A on Windows or Command+A on Mac before choosing the spacing.

Adding empty lines instead of changing line spacing. Pressing Enter repeatedly creates extra paragraphs. It can make a page look spaced out, but it is not the same as double line spacing. It also makes edits awkward: deleting or moving text can leave uneven gaps. Use the 2.0 spacing option instead.

Confusing line spacing with paragraph spacing. Line spacing controls the distance between lines inside a paragraph. Paragraph spacing adds room before or after whole paragraphs. If the lines within each paragraph look double-spaced but there is still a large gap between paragraphs, that extra space may be paragraph spacing rather than a problem with the 2.0 setting.

Changing only part of the document by accident. A selection can stop at a page break, heading, or paragraph boundary. If the first page looks right but later pages do not, select the remaining text and apply 2.0 again, or select all text and repeat the change. Be careful if different sections are supposed to retain different formatting.

Expecting the page count to stay the same. Double spacing increases the length of the document on screen and often adds pages. That is normal. Do not remove text or shrink the font simply because the page count increases unless your instructions also require those changes.

Tips

If you are formatting an assignment, check the instructions before changing anything else. Double spacing is a line-spacing requirement; it does not automatically specify font, margins, paragraph indents, or spacing after paragraphs. Keep those settings as required rather than assuming 2.0 changes them.

For a clean document-wide result, select all text first and apply 2.0 once. Then inspect headings, lists, and text in tables, because those elements may use their own styles or have different spacing. If a heading is meant to remain single-spaced, select and format that heading separately after applying the whole-document change.

Use the menu’s visible value as your check: 2.0 means double line spacing. A visual comparison can be misleading because font size, zoom level, and paragraph spacing affect how open the page looks. If you are unsure, select a paragraph and reopen the spacing menu to see which option is active.

When working on only a passage, select complete paragraphs when practical. Paragraph formatting is attached to paragraphs, so selecting a few words can make it unclear which paragraph settings you have changed. Selecting from the start of the first paragraph through the end of the last one makes the intended scope easier to verify.

If you need a paper copy or a PDF, preview the final layout after applying spacing. Double spacing can push a heading or a short final paragraph to another page. Use print preview or export options available in Word for the web to review page breaks, rather than inserting extra blank lines to force a particular layout.

Troubleshooting

The spacing button is missing. Confirm that you are in the editing view and have selected the Home tab. In a narrow browser window, the ribbon can collapse controls into smaller menus. Expand the browser window, look through the paragraph formatting group, or open the ribbon’s additional-options menu. If you have view-only access, ask for editing permission or make an editable copy if that is allowed.

The change affects only one paragraph. The selection may not have included the rest of the document. Click in the document body, use Ctrl+A on Windows or Command+A on Mac, and check that the text is selected. Then choose Home > Line and Paragraph Spacing > 2.0. If only a particular section needs changing, select that section carefully instead of applying the setting to everything.

The page still looks too crowded. First distinguish crowded lines from tight margins or small text. Double spacing changes the vertical distance between lines, but does not enlarge the font, widen margins, or add space around a page. Select a paragraph and confirm that 2.0 is active. If the lines are separated but paragraphs are still crowded together, inspect the paragraph-spacing options in the same menu; the extra gap between paragraphs is a separate setting.

Some paragraphs do not match. Different styles, lists, tables, or pasted text may carry different formatting. Select the paragraphs that remain incorrect and apply 2.0 directly. If you want a heading or a table to stay as it is, do not include it in that selection. For text pasted from another source, applying the spacing after pasting can be simpler than trying to preserve inconsistent formatting from the source.

The change seems to disappear or is not saved. Check that you are in the right document and that you have not opened a read-only copy. Wait for Word’s save indicator before closing the browser tab, and confirm that the browser is online. If the document is shared, another person’s edits or a conflict may affect what you see. Reopen the file and check the spacing; if necessary, apply the setting again and allow it time to save.

Frequently Asked Questions

Does 2.0 mean double spacing in Word for the web?
Yes. The 2.0 option sets double line spacing for the selected text or paragraphs. Choose that option rather than 1.5 or manually inserting blank lines.

How do I double-space the entire document?
Click in the document text, press Ctrl+A on Windows or Command+A on Mac, then select Home > Line and Paragraph Spacing > 2.0. Review headings, lists, and tables afterward if they should have different formatting.

Can I double-space just one paragraph?
Yes. Select the paragraph, or place the cursor in it, then choose Home > Line and Paragraph Spacing > 2.0. Check the paragraph after applying the setting to make sure the lines within it have more space.

Will double spacing add blank lines between paragraphs?
No. It increases the distance between lines within paragraphs. Extra space before or after paragraphs is a separate paragraph-spacing setting, so a document can be double-spaced and still have additional paragraph gaps.

Does this work differently in the desktop version of Word?
The basic approach is similar: select text, open the Home tab’s line and paragraph spacing controls, and choose 2.0. The ribbon layout can differ between Word for the web and desktop Word, but the setting has the same purpose.

Will new text also be double-spaced?
Often, typing in a double-spaced paragraph carries its formatting into the text that follows. However, a new paragraph may use a different style or formatting. Check the new paragraph and select it to apply 2.0 if needed.
