Double Space in Word Online: Step-by-Step Instructions

To double-space text in Word Online, select the text, open Home > Line and Paragraph Spacing, and choose 2.0. To format the whole document, click in its main text and select all before choosing 2.0. Double spacing increases the distance between lines; it does not automatically add extra space between paragraphs.

What You’ll Need

A browser with access to Word for the web and the document you want to edit.
Permission to edit the document. If it opens as read-only, you may need to request access or create an editable copy.
A clear idea of what should be double-spaced: a passage, selected paragraphs, or the main text throughout the document.

You do not need to install an add-in or change a computer setting. Word Online saves edits to the document’s cloud storage as you work, though it is sensible to confirm the save status before closing the tab.

Step-by-Step

Open the document in editing mode. Sign in to Microsoft 365, open the document from OneDrive or SharePoint, or open it from Word’s home page. If you see a read-only view, choose the available editing option, such as Edit Document > Edit in Browser. The wording can vary with the account or sharing permissions. Make sure the document is open in Word for the web, rather than just in a preview.
Decide how much text to format. To double-space only a section, drag over that text, or click within a paragraph if you want to format that paragraph. To format the document’s main text, click in its body text and press Ctrl+A on Windows. On a Mac, press Command+A. In a browser-based editor, the selection shortcut can behave differently if focus is outside the document, so click in the text first. Confirm that the intended content is highlighted before moving on.
Open the spacing controls. Select the Home tab on the ribbon. Find Line and Paragraph Spacing, usually in the Paragraph area. Its icon commonly looks like horizontal lines with up-and-down arrows. If the ribbon is compact and the control is not visible, look for an overflow menu such as the three-dot More menu, or widen the browser window. You can also try collapsing or expanding the ribbon to expose its full set of controls.
Choose 2.0. Open Line and Paragraph Spacing and click 2.0 in the list. Word applies double line spacing to the selected paragraphs or text. You do not need to insert blank lines manually. The formatting should take effect immediately, and the highlighted text may remain selected until you click elsewhere.
Check the result in the document. Look at several lines, including lines that wrap across the page. Double spacing increases the vertical distance between successive lines in a paragraph. If you selected the entire main text, scroll to a few different parts of the document to check that the formatting is consistent. If you selected only a passage, verify that text outside it still has the spacing you intended.
Finish the selection and confirm the save. Click in an ordinary part of the document to remove the highlight. Word for the web normally saves changes automatically to OneDrive or SharePoint. Look for a saved or up-to-date status if Word displays one, and give it a moment to finish syncing before closing the tab. If the file is shared, other editors may also be making changes, so check that the spacing remains as expected after collaboration updates.

The same ribbon method works when you want to format a few paragraphs rather than the whole document: select just those paragraphs, then choose 2.0. You can also click in a single paragraph without selecting every character in it; paragraph-level spacing applies to the paragraph at the cursor. When selecting carefully, include the paragraph mark only if you need to carry paragraph formatting with the selection, but for a normal paragraph, placing the cursor inside it is usually enough.

Common Mistakes

Choosing 1.5 instead of 2.0. The spacing menu offers several options, and 1.5 may look more open than single spacing. For standard double spacing, select the option explicitly labeled 2.0. Do not judge by appearance alone: font size, line length, and screen zoom can make spacing differences hard to compare.

Adding blank lines instead of changing line spacing. Pressing Enter repeatedly creates extra paragraphs, not true double spacing. This can produce uneven gaps, make pagination unpredictable, and leave large holes if the text is edited later. Use the spacing control so Word adjusts the line spacing as a formatting property.

Forgetting to select the intended text. If you want the whole document double-spaced but have only one paragraph selected, only that paragraph may change. Conversely, selecting everything when you only meant to format a quotation can change more than you intended. Check the highlight before choosing 2.0, and use Undo (Ctrl+Z on Windows or Command+Z on Mac) promptly if the wrong content changes.

Confusing line spacing with paragraph spacing. A document may still show a noticeable gap between paragraphs after you apply 2.0. That gap can come from separate space-before or space-after settings. Double spacing controls the distance between lines within paragraphs; paragraph spacing controls the gap around paragraph boundaries. They are related visually but are not the same setting.

Expecting every part of the file to change. Selecting the main body text may not include material in headers, footers, text boxes, or other separate areas. Tables can also require you to select their cell text or paragraphs separately. Check any special sections that must meet the same formatting requirement instead of assuming a body-text selection covered them.

Tips

Format only what the instructions require. If an assignment asks for double-spaced body text but leaves headings, captions, or footnotes unspecified, avoid changing those areas automatically without checking the requirements. Select the body paragraphs and apply 2.0 to that selection. If the whole document must be double-spaced, selecting all the main text is faster, but review title pages and other special elements afterward.

Keep paragraph gaps consistent. If the text looks as though it has an extra blank line between every paragraph, inspect Home > Line and Paragraph Spacing for paragraph-spacing options. Depending on the selected paragraph and the version of the web interface, you may see commands such as Add Space Before Paragraph or Remove Space After Paragraph. Use the relevant command only if you want to change those gaps; it is not necessary just to set line spacing to 2.0.

Use a small test selection when unsure. Select one paragraph and choose 2.0 first. This lets you see the appearance and confirm that you found the right command before applying it to many pages. If it is correct, select the remaining intended text and repeat the same menu choice. This is especially helpful in a document that already contains headings, lists, tables, or mixed formatting.

Use the ribbon rather than relying on a shortcut. Word desktop has keyboard shortcuts for line spacing, but keyboard behavior can vary in Word for the web and between browsers. The visible Home > Line and Paragraph Spacing > 2.0 path is a reliable way to choose the exact setting. On a Mac, the ribbon labels are generally the same; use Command rather than Ctrl for selecting all text when appropriate.

Review page breaks after formatting. Double spacing adds vertical height, so text may move onto later pages or create a new page. That is a normal result, not necessarily a formatting error. Review page breaks, headings near the bottom of pages, and any page-numbered sections after the change. Avoid deleting text or inserting repeated blank paragraphs just to force the document back to its previous page count.

Troubleshooting

The spacing button is missing. Confirm that the document is open in edit mode and that the Home tab is selected. If the browser window is narrow, the ribbon may hide some controls under a three-dot or More menu. Expand the window or ribbon and look in the Paragraph controls. If you are viewing a preview or a read-only document, switch to editing mode if you have permission.

Only some paragraphs changed. The usual cause is that only part of the document was selected. Click into the main text, select all with Ctrl+A on Windows or Command+A on Mac, and choose 2.0 again. Before doing so, consider whether you want headings and other special content included. If the selection is correct but some areas remain unchanged, inspect separate items such as text boxes, headers, footers, and table content and format those individually.

The lines look double-spaced, but the gaps between paragraphs still seem too large. Check whether space before or after paragraphs is also turned on. Open the spacing menu and remove extra paragraph spacing if that is what you want. Do not switch away from 2.0 to solve a paragraph-gap problem; that would change the distance between lines within the paragraphs as well.

The change disappears or does not save. Check whether the file is still syncing and whether you have editing permission. A connection interruption can delay cloud saving, so wait for Word to show an up-to-date status before closing the page. If the document is shared, refresh only after allowing time for pending edits to save. If you cannot edit the original, ask the owner for access or use an editable copy if that is permitted.

The menu choice seems to have no effect. Confirm that the text is selected, choose 2.0 again, then click elsewhere to inspect the result. If the text is inside a table, make sure you selected the relevant cell content rather than only clicking the table border. Also check whether a different region of the document is selected or whether the page is still in viewing mode. Undo any unintended change and repeat the operation with a clear selection.

Frequently Asked Questions

How do I double-space the entire document in Word Online?
Click in the document’s main text, press Ctrl+A on Windows or Command+A on Mac, then choose Home > Line and Paragraph Spacing > 2.0. Review separate areas such as headers, footers, and text boxes if they also need formatting.

Can I double-space just one paragraph?
Yes. Click inside the paragraph, or select the paragraph text, and choose Home > Line and Paragraph Spacing > 2.0. Other paragraphs should keep their existing line-spacing setting.

Does 2.0 add a blank line after each paragraph?
No. It doubles the line spacing within paragraphs. Extra space between paragraphs is a separate paragraph-formatting setting, and pressing Enter to create blank lines is not the same as applying double spacing.

Will double spacing change the font or margins?
No. Choosing 2.0 changes line spacing, not the typeface, font size, or page margins. It can change how much text fits on each page, so page breaks and the total page count may change.

Can I use the same steps on Word for Mac?
Word Online uses the same Home ribbon spacing menu on a Mac. The main shortcut difference is selecting all text: use Command+A on Mac instead of Ctrl+A on Windows. If a shortcut behaves unexpectedly in the browser, use the ribbon controls.

How can I undo double spacing?
Select the affected paragraphs and choose the spacing option you want, such as 1.0 or 1.15, from the same menu. If you just applied the change and have not made other edits since, use Undo: Ctrl+Z on Windows or Command+Z on Mac.
