How to Double Space in Word for the Web, Step by Step

To double-space text in Word for the web, select the text, then choose Home > Line and Paragraph Spacing > 2.0. To apply it to the whole document, click in the document, select all its text, and use the same menu. Double spacing adds vertical room between lines, which can make a draft easier to read, edit, or annotate.

You can do this in a browser without installing the desktop version of Word. The labels or ribbon layout may look slightly different depending on your screen size, but the spacing control is on the Home tab.

What You’ll Need

A document opened in Word for the web with editing access. If it opens in read-only mode, request permission or use the available editing option first.
A web browser and an internet connection so Word can load and save your document.
A keyboard or mouse to select the text you want to format. No add-in or special setting is required.

Step-by-Step

Open the document in editing mode. Go to Word for the web and open the file from your recent documents or its storage location. If you are viewing a shared file, check that you have permission to edit. If Word displays a button or menu for switching from viewing to editing, choose the editing option. Wait for the document and ribbon to finish loading before changing formatting.
Decide what should be double-spaced. You can format one paragraph, several paragraphs, or the entire document. To change one paragraph, click inside it; selecting every word in the paragraph is not usually necessary because line spacing is a paragraph setting. To format only a portion or several specific paragraphs, drag across the text you want, or click at the start, hold Shift, and click at the end. Take care not to include a heading or other text that should keep its current spacing.
Select the whole document if that is your goal. Click in the document’s text area, then press Ctrl+A on Windows or Command+A on Mac. If the first press selects only a word or a smaller area, click in the document body again and repeat. Confirm that the document text, rather than text in a search box or another field, is selected. You can also select all by dragging through the document, but the keyboard shortcut is usually easier for a long file.
Open the spacing menu. Select the Home tab on the ribbon. Find Line and Paragraph Spacing in the paragraph-formatting controls and open its dropdown menu. Depending on the window width, the ribbon may be condensed, so the control may appear as a small icon with lines and vertical arrows or inside a compact paragraph menu. If you cannot see it, widen the browser window or look for a more-options control on the Home tab.
Choose 2.0. In the spacing menu, select 2.0. Word applies double line spacing to the selected paragraph or text range. If you selected the whole document, the change should apply across its body text. The page may become longer, and some paragraphs may move to another page; that is a normal result of adding space between lines.
Check the result and let Word save. Click in a few places in the document to confirm that the intended paragraphs have wider line spacing. If you formatted all text, check a paragraph near the beginning and another farther down. Word for the web generally saves changes to the online file automatically; wait for any saving indicator to finish before closing the tab. If your organization uses a different storage or connection setup, confirm the document shows that it is saved.

For a paragraph that is already selected, you can also use the ribbon menu without clicking elsewhere. Clicking elsewhere first may remove the selection, so choose the spacing option while the intended text is still highlighted. If you accidentally format the wrong area, use Ctrl+Z on Windows or Command+Z on Mac to undo the change, then select the correct text and repeat the steps.

Common Mistakes

Changing paragraph spacing instead of line spacing. Word has separate controls for the distance between lines inside a paragraph and the space before or after a paragraph. Selecting a larger paragraph-after value can make paragraphs farther apart without making the lines within each paragraph double-spaced. Choose the 2.0 line-spacing option, not a command that only adds space before or after paragraphs.

Formatting only the current paragraph by mistake. If you click into one paragraph without selecting other text, Word changes that paragraph, not necessarily the full document. For document-wide formatting, select all the document text first. Conversely, if you only mean to change one section, avoid Ctrl+A or Command+A, since those shortcuts can select everything in the editing area.

Including headings or lists unintentionally. A whole-document selection can affect headings, bullet lists, tables, and other content as well as ordinary paragraphs. That may be correct for a uniform assignment, but it can also make headings look too spread out or change the appearance of a list. If you need different spacing for different parts, format the body text and headings separately.

Expecting the page count to stay the same. Double spacing increases the amount of vertical space used, so text can flow onto additional pages. It does not normally add blank paragraphs or change the words in the document. Avoid deleting text just to restore the previous page count unless that is genuinely what you intend.

Assuming the change did not work because the display looks subtle. Zoom level, font size, and the amount of text on screen can make the difference less obvious. Compare two or three lines in the same paragraph, or check the spacing menu again with the cursor in that paragraph. A selected 2.0 option is a more reliable check than judging the page length alone.

Tips

Use the cursor as a quick way to format one paragraph. When the insertion point is inside a paragraph and no text is selected, applying 2.0 generally changes the paragraph containing that cursor. This is useful for a single paragraph. To apply the setting to a group, select the text spanning the paragraphs first; selecting the whole paragraph is often easier than trying to click each one separately.

Separate body text from special formatting. If an assignment asks for double-spaced body copy but does not specify headings, title lines, or footnotes, check its instructions before formatting everything. You can select the main body text and apply 2.0, then leave the title or headings at their existing spacing. This avoids making every element look identical when the document uses a deliberate layout.

Use the same menu to change spacing later. If 2.0 looks too loose or you need to return to single spacing, select the affected text and choose the appropriate line-spacing value from the same Home-tab menu. A value of 1.0 is single spacing; 1.5 is one-and-a-half spacing. Reapply the setting to the intended range rather than adding empty lines between lines manually.

Remember that formatting follows paragraphs. When you press Enter to start a new paragraph, the new paragraph often inherits formatting from the paragraph before it. If new text unexpectedly remains double-spaced, check the spacing setting at the insertion point. If you only want one section to be double-spaced, start the next section in a paragraph with the spacing you want, or select that section and apply its setting explicitly.

Review the document after a large change. Check page breaks, headings, lists, and tables after applying double spacing to a long document. The text itself should remain intact, but new page breaks can separate a heading from the paragraph that follows or move a table. Adjust the layout only if the new page flow makes the document harder to read.

Troubleshooting

The spacing control is missing. Make sure the Home tab is active and that the document is open for editing. In a narrow browser window, Word may collapse ribbon controls; maximize the window, widen it, or inspect the compact controls and additional-options menu. If you are using a phone or tablet browser, the ribbon can be more limited, so try a desktop-sized browser window if possible.

The text is still single-spaced after choosing 2.0. First check that you chose the 2.0 line-spacing option, rather than a paragraph-spacing command. Then click inside a paragraph that should have changed and reopen Home > Line and Paragraph Spacing to see which value is active. If the wrong paragraph changed, select the intended range and apply 2.0 again. Formatting applied to one selection will not automatically update unrelated text elsewhere.

Only some paragraphs changed. This usually means the selection did not cover the whole intended range, or some content was outside the selection. Select the missing paragraphs and apply 2.0 to them. If the document has separate sections with different formatting, check each section rather than assuming one selection reached every part. Tables and text boxes can also require you to click inside them and format their text separately.

The document is read-only or the ribbon will not respond. Check whether you have editing permission and whether the file has finished loading. A shared document owner may need to grant edit access. If the browser shows a connection problem, reconnect and wait for the file to sync before making more changes. Avoid making duplicate edits in multiple open copies of the same file, since that can make it harder to tell which version contains the latest formatting.

The page count increased or a page looks unexpectedly crowded. This is a normal possible effect of double spacing. Review page breaks and paragraph flow rather than removing blank lines at random. If only one part needs double spacing, undo the whole-document change and apply 2.0 to just that section. If a heading is stranded at the bottom of a page, adjust the document layout or paragraph formatting as appropriate for your requirements.

Frequently Asked Questions

Can I double-space the entire document in Word for the web?
Yes. 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 headings, lists, and tables afterward because the selection may format those too.

Can I double-space just one paragraph?
Yes. Click inside the paragraph and choose 2.0 from the Home-tab spacing menu. If you want to change several paragraphs, select the text across those paragraphs before opening the menu.

Does double spacing mean adding an empty line after every line?
No. Double spacing increases the line spacing within paragraphs. Pressing Enter repeatedly inserts new paragraphs or blank lines, which is a different change and can create inconsistent layout.

Will double spacing change my font or margins?
No. The 2.0 setting changes line spacing; it does not by itself change the font, font size, or page margins. The document may take more pages because the lines are farther apart.

Are the steps different in the desktop Word app?
The basic control is similar: select the text, go to Home > Line and Paragraph Spacing, and choose 2.0. The ribbon layout can differ between Word for the web and desktop Word, and Mac keyboard shortcuts use Command where Windows uses Ctrl for selecting or undoing text.

How do I return to single spacing?
Select the affected text, open Home > Line and Paragraph Spacing, and choose 1.0. If only one paragraph needs changing, place the cursor in that paragraph instead of selecting the whole document.
