How to Double Space in Word Mobile

To double-space text in Word Mobile, select the text, open the Home tab, choose Line Spacing or Paragraph Formatting, and tap 2.0. To change the whole document, select all of its text first. The exact button placement can differ slightly between iPhone, iPad, and Android, but the spacing control is in the Home formatting tools.

What You’ll Need

A phone or tablet with the Microsoft Word app installed.
A document you can edit. If it opens in read-only mode, sign in if prompted or make an editable copy first.
The document text you want to format. You can change a few paragraphs, a selection, or the entire document.

Step-by-Step

Open the document in the Word app. Find the file in Word’s recent list, OneDrive, or your device storage, then tap it. If it opens in reading view, tap the pencil or Edit control to enter editing mode. The toolbar may be collapsed when the screen is narrow; tapping the editing or ribbon control should reveal it.
Select the text you want to double-space. For a few lines or paragraphs, press and hold a word, then adjust the selection handles until the whole passage is highlighted. You can include a paragraph mark by extending the selection to the end of the paragraph; this can help carry paragraph formatting consistently. If you want to format the full document, tap within the document and use Select All from the editing or text-selection menu if it appears. On a connected keyboard, use Ctrl+A on Windows or a Windows-layout keyboard, or Command+A on an Apple keyboard. Check that the selection covers the intended content before changing the format.
Open the Home formatting controls. Tap Home on the ribbon if another tab is open. In the mobile layout, the ribbon may show only a few icons at first. Look for Paragraph Formatting or an icon with horizontal lines and spacing arrows, and tap it. On some app versions, Line Spacing is visible directly in the Home ribbon, so you can open it without an extra menu.
Choose a line spacing value of 2.0. In the paragraph formatting menu, tap Line Spacing if it is a separate option, then select 2.0. Some versions show the spacing choices immediately after opening Paragraph Formatting. The menu may display values such as 1.0, 1.15, 1.5, and 2.0. Choose 2.0 for standard double spacing. The selected text should update as soon as you tap the value; you do not normally need to press Enter or save the formatting separately.
Review the result and selection. Tap outside the highlighted text to see the page more clearly. The lines within each paragraph should now have visibly more vertical space. Scroll through the passage or document to confirm that the change reached all the paragraphs you selected. If only one paragraph changed, repeat the selection carefully and apply 2.0 again.
Save or let Word sync the document. Word commonly saves changes automatically, especially for files stored in OneDrive, but wait for any saving or syncing indicator to finish before closing the file. If the document is stored locally, use the app’s save control if one is displayed. Reopen the document if needed to confirm that the formatting remains.

To double-space only new text in a particular paragraph, tap inside that paragraph and set its line spacing to 2.0 before typing. Word applies paragraph formatting to the paragraph where the insertion point sits, even when no words are selected. This does not necessarily change the rest of the document, so use Select All when the whole file needs the same spacing.

Common Mistakes

Changing the wrong amount of text. Tapping a paragraph without selecting other paragraphs usually changes only the paragraph containing the cursor. For a full-document change, select all first. For a limited change, make sure the highlight includes every intended paragraph.
Choosing 1.5 instead of 2.0. The spacing choices can be close together in a compact menu. Confirm that the selected value is explicitly 2.0, rather than 1.5 or 1.15.
Adding blank lines instead of setting line spacing. Pressing Return twice creates extra paragraphs and may leave uneven gaps. Double spacing is a paragraph-formatting setting: use Line Spacing and choose 2.0 rather than inserting empty lines.
Confusing line spacing with spacing after paragraphs. Line spacing controls the distance between lines within a paragraph. Spacing Before or After adds extra room between separate paragraphs. If the text looks unusually spread out between paragraphs, those paragraph-spacing settings may also be in effect.
Formatting while the document is in reading view. A document can be open without being editable. Switch to Edit mode, check that the selection and formatting controls are available, and verify that you have permission to change the file.
Expecting every page to look identical. Double spacing makes a document longer and can move headings, page breaks, and images to new positions. That is a normal layout change, not necessarily a formatting error.

Tips

Apply the setting before writing a long assignment. Set the paragraph to 2.0 first, then continue typing. New paragraphs often carry forward the formatting of the paragraph you just used, although a document’s styles or existing formatting can affect this behavior.
Keep headings readable. If you select the entire document, headings may also become double-spaced. That can be appropriate when instructions require every line to be double-spaced, but some formats use different spacing for headings. Follow the requested style rather than assuming every part must match.
Use a selection for selective changes. To leave a title, footnotes, or a reference list unchanged, do not select all. Highlight only the body paragraphs that need double spacing, and inspect the boundaries of the selection before choosing 2.0.
Look at the document at a useful zoom. Mobile page layout can make line spacing look compressed on a small screen. Zoom in or switch to a page view if available, then inspect a normal paragraph rather than judging from a heading or a short line.
Know what double spacing does not change. It does not automatically change font size, margins, indentation, or the space between separate paragraphs. Set those separately only if your instructions require them.
Be aware of app layout differences. Word for iOS and Word for Android can arrange the Home ribbon and paragraph menu differently, and updates may move a control. Look for the Line Spacing label or paragraph-lines icon inside Home formatting rather than relying on an icon’s exact screen position.

Troubleshooting

I cannot find Line Spacing. First make sure the document is in Edit mode and the Home tab is open. Expand the ribbon or tap Paragraph Formatting to reveal more controls. If the menu is scrollable, swipe within the menu to see additional options. Update Word from your device’s app store if the control is still missing, then reopen the document. The precise label and icon can vary by app version.

Only some paragraphs changed. The original selection may have ended early, or the cursor may have been in just one paragraph. Select the remaining text—or use Select All if the full document should match—and choose 2.0 again. If selecting all is difficult on a phone, work through the document in manageable sections and check each section after applying the setting.

The lines look double-spaced, but the gaps between paragraphs are huge. You may have both 2.0 line spacing and extra paragraph spacing. Tap in the affected paragraph and inspect the paragraph-formatting controls for Spacing Before or Spacing After. Reduce those values only if the assignment or document style calls for no extra paragraph gap. Do not lower the line spacing if you still need double-spaced lines.

The change disappears or will not save. Confirm that you are editing the correct copy and have permission to edit it. For a cloud file, check the connection and wait for synchronization to finish. If you see a read-only notice, save or copy the file to a location where you can edit it, then apply the formatting to that copy. Avoid closing the app while a save or upload is still in progress.

The document looks different after changing spacing. Double spacing increases the page count and can shift content onto later pages. Review page breaks and any manually inserted blank paragraphs. If the layout change is unwanted, use Undo soon after applying the setting, then select the correct text and try again. Undo behavior can be limited after closing or reopening a document, so save a copy before making substantial formatting changes.

Frequently Asked Questions

Can I double-space an entire Word document on my phone?
Yes. Select all the document text, open the Home paragraph-formatting controls, and set Line Spacing to 2.0. Check the beginning and end of the document afterward to make sure the whole selection was included.

Can I double-space only one paragraph?
Yes. Tap inside the paragraph, open the Line Spacing control, and choose 2.0. You usually do not need to highlight the paragraph if you only want to change the paragraph containing the cursor.

Does Word Mobile have a double-space button?
It generally offers a line-spacing menu rather than a separate button labeled Double Space. Choose the 2.0 setting in Line Spacing or Paragraph Formatting.

Is double spacing the same as adding a blank line?
No. Double spacing increases the distance between the lines of text within a paragraph. A blank line is a separate empty paragraph and creates a larger, less consistent gap.

Will double spacing change the document’s page count?
Usually, yes. More vertical space means fewer lines fit on each page, so text may move onto additional pages. The exact change depends on the document’s length, margins, font, and existing layout.

Do the instructions differ on iPhone and Android?
The basic process is the same: select text, open Home formatting, and choose 2.0 for line spacing. The ribbon layout and the route into Paragraph Formatting can vary, so look for the line-spacing label or paragraph-formatting icon in your version of Word.
