How to Double Space in Word for the Web: A Quick Guide

To double-space text in Word for the web, select the text, open Home > Line and Paragraph Spacing, and choose 2.0. To apply it to the whole document, click in the document, select all its text, then choose 2.0. This changes the distance between lines; it does not add a blank line after every paragraph.

You can use the same control for one paragraph, a group of paragraphs, or the entire document. If the result looks wider than expected, check paragraph spacing as well as line spacing: they are separate settings.

What You’ll Need

A web browser and access to Word for the web at Microsoft 365.
A document you can edit. If it is view-only, ask for editing access or make an editable copy first.
A keyboard and mouse or trackpad to select text and use the ribbon. You can also use keyboard shortcuts to select the document.

Step-by-Step

Open the document in editing mode. Sign in to Microsoft 365, open Word, and choose the document. If it opens in Reading view, select the option to edit it, such as Edit Document or Editing. The available label can vary with how the file was opened and your access permissions. Wait for the document to finish loading before changing its formatting.
Decide what should be double-spaced. To format just a section, use the mouse or trackpad to select that text. You can select a few sentences, several paragraphs, or a heading and its following text. If you only click inside a paragraph without selecting a range, the spacing command generally applies to the paragraph where the insertion point is. Selecting text within a paragraph still changes the line spacing for that paragraph, rather than only the one selected line.
Select the whole document if that is your goal. Click inside the document text first, then press Ctrl+A on Windows or Command+A on Mac. Check that the document content is selected before proceeding. If the shortcut selects the browser page or does not select the expected text, click directly in the document body and try again. For a short document, you can instead drag from its beginning to its end.
Open the spacing menu on the Home tab. On the ribbon, select Home. Find Line and Paragraph Spacing in the paragraph formatting area. Its icon commonly looks like horizontal lines with vertical arrows. Select the control to open its menu. If the ribbon is simplified or narrow, some controls may be tucked into an overflow menu; widen the browser window or expand the ribbon to find them.
Choose 2.0. In the spacing menu, select 2.0. Word applies double line spacing to the selected paragraphs. The change should appear immediately. If nothing seems to happen, check that you are in editing mode, that the intended text is selected, and that you chose 2.0 rather than a paragraph-spacing command.
Review the result at normal zoom. Scroll through the formatted area and look at both the lines within paragraphs and the gaps between paragraphs. If you selected the whole document, check headings, lists, tables, and text near page breaks too. A long document may reflow onto additional pages after the spacing changes; that is expected because double spacing takes up more vertical room.
Clear the selection and confirm the formatting. Click in the document or use the arrow keys, then check a few paragraphs. If only one part was meant to change, make sure text outside that section has retained its earlier spacing. Word for the web saves changes to a cloud document automatically when connected, but wait for any saving indicator to finish before closing the tab. If you are working with a downloaded copy, save or download the updated file as needed.

To double-space text you have not typed yet, place the cursor in the paragraph where you want to begin, open the same menu, and choose 2.0 before typing. The following paragraph may inherit its formatting when you press Enter. Check it as you go, especially if you are typing after a heading, list, or differently formatted paragraph.

Common Mistakes

Adding blank lines instead of changing line spacing. Pressing Enter twice creates extra paragraphs and can leave uneven gaps. Choose 2.0 in the line-spacing menu instead. Blank lines are separate paragraph breaks and may behave differently when you edit or change page layout.
Changing paragraph spacing instead of line spacing. Commands such as Add Space After Paragraph create a gap between paragraphs. They do not set the distance between lines within a paragraph. Use the 2.0 line-spacing option for true double spacing.
Formatting only the current paragraph by accident. If your goal is the whole document, click in the body and select all before choosing 2.0. Applying the command with no text range selected can affect only the paragraph at the cursor.
Assuming every type of content will look identical. Tables, lists, footnotes, and headings can have their own paragraph formatting or layout constraints. Inspect them after applying the change; a table may become taller, and a heading may retain its own spacing before or after it.
Expecting the page count to stay the same. Double spacing increases the height of the text, so page breaks and the total number of pages can change. That does not by itself mean the setting was applied incorrectly.

Tips

Format only the required range. If an assignment asks for double-spaced body text but single-spaced headings, select the body paragraphs rather than using Select All. You can format separated areas individually if needed.
Use the menu rather than relying on a shortcut. Word desktop has keyboard shortcuts for line spacing, but shortcuts can differ by platform, browser, and focus. The ribbon control in Word for the web is the clearest way to choose 2.0.
Keep line spacing and paragraph gaps in mind separately. A document can be double-spaced and still have extra space after each paragraph. If the gaps look unusually large, inspect the paragraph-spacing options rather than changing the line-spacing value.
Check the document at a readable zoom. At a very small zoom, double spacing can be hard to distinguish. Use the status bar zoom control or your browser’s zoom settings to inspect a representative paragraph.
Make a copy before a large formatting change when appropriate. For a shared or important document, use File options to make a copy if available, or confirm that version history is enabled for the file. This gives you a way to recover the earlier layout if a broad selection changes more than intended.

Troubleshooting

The spacing menu is missing. Confirm that the document is open in Word for the web and that you are editing rather than viewing. Select the Home tab, expand a collapsed ribbon if necessary, and look in the paragraph formatting controls. On a narrow screen, browser zoom or window width may hide some ribbon buttons; widening the window can reveal them.

The text does not change after you select 2.0. Click in the document and select the intended text again, then repeat Home > Line and Paragraph Spacing > 2.0. If the document is read-only, switch to editing if permitted. If Word is offline or still saving, reconnect and wait for the update to sync. You can also refresh after confirming that the latest edits have been saved.

The gap between paragraphs is still too large. Double spacing controls the lines inside paragraphs, while paragraph spacing controls the gap before or after a paragraph. Select the affected paragraphs and open the spacing menu to review the paragraph-spacing choices. Remove extra space before or after if the document requires uniform paragraph gaps, but do not confuse that adjustment with the 2.0 line-spacing setting.

Only some paragraphs are double-spaced. That usually means the selection covered only part of the document or some paragraphs have different formatting. Select the missing paragraphs and apply 2.0. If the whole document should match, select all of its text and set 2.0 again, then check special areas such as tables and lists.

The document looks different when opened in desktop Word. Word for the web and desktop Word can display some page layouts differently, and fonts or other formatting may affect line wrapping. Check that the same paragraphs have 2.0 line spacing in the desktop app as well. On Windows desktop Word, the line-spacing control is on Home > Line and Paragraph Spacing; Mac desktop Word has the equivalent control on its Home ribbon. The interface may vary slightly by version, so use the control labeled for line and paragraph spacing.

Frequently Asked Questions

Does 2.0 mean double spacing?

Yes. In Word’s line-spacing menu, 2.0 is the double-spacing setting. It increases the distance between lines within a paragraph. It is different from adding a blank line or extra space after a paragraph.

Can I double-space only one paragraph?

Yes. Click in that paragraph, or select text within it, then choose Home > Line and Paragraph Spacing > 2.0. Line spacing is a paragraph-level format, so the paragraph’s lines will use the setting even if you selected only part of its text.

How do I double-space the entire document?

Click inside the document body, press Ctrl+A on Windows or Command+A on Mac, then choose Home > Line and Paragraph Spacing > 2.0. Review headings, lists, and tables afterward because they may have special formatting.

Will double spacing add blank lines between paragraphs?

No. It increases the line spacing within paragraphs. A separate paragraph-spacing setting controls gaps before or after paragraphs, and pressing Enter creates a new paragraph. Use the appropriate setting for the layout you need.

Can I use a keyboard shortcut in Word for the web?

You can use Ctrl+A on Windows or Command+A on Mac to select the document content after clicking in it. For choosing 2.0, use the ribbon menu: desktop Word shortcuts may not work consistently in a browser, so the menu is the reliable option.

Does Word for the web save the change automatically?

For a cloud document with an active connection, Word for the web normally saves edits automatically. Wait for the saving status to finish before closing the tab. If you are editing a local or downloaded file, save or download the updated copy yourself.
