Common Problems When Setting 1.5 Line Spacing in Word
If your spacing isn’t changing the way you expect, one of these four issues is usually the cause.
Spacing won’t change after pressing Ctrl + 5
You haven’t selected the text first. Press Ctrl + A to select the whole document, then press Ctrl + 5 again.
Only one paragraph changes when I want the whole document
Line spacing only applies to selected text. Select the whole document with Ctrl + A before applying the spacing.
The style keeps resetting my spacing
Your paragraph style (Normal, Heading 1, etc.) has its own built-in spacing. Modify the style directly under Home → Styles → Modify so 1.5 line spacing becomes the default for that style.
The spacing looks wider than 1.5 even after applying it
Word is adding extra space before or after the paragraph. Open Paragraph settings and set Before and After to 0 pt so only the 1.5 line spacing controls the layout.
Pro Tips
- Set 1.5 line spacing as the default for new documents by modifying the Normal style — it saves repeating the same step every time.
- Pair 1.5 spacing with justified alignment for the cleanest academic look — see how to justify text in Microsoft Word for the full setup.
- If you’re submitting an academic paper, check the brief — many universities now specify 1.5 spacing instead of double, so this is often the safer default.
- For mixed spacing (cover page single-spaced, body 1.5), apply spacing section by section rather than to the whole document.
FAQs
What is 1.5 line spacing in Word?
1.5 line spacing in Word means there is one-and-a-half lines of vertical space between each line of text — wider than single spacing but tighter than double spacing.
What is the shortcut for 1.5 line spacing in Word?
Select the text first, then press Ctrl + 5. This shortcut works on every modern version of Word, including Word 2016, 2019, 2021, and Microsoft 365.
Why is my line spacing not changing in Word?
Either no text is selected, or your paragraph style is overriding the setting. Select the text with Ctrl + A, or modify the underlying style directly to lock the new spacing in.
Is 1.5 line spacing better than double spacing?
It depends on the requirement. 1.5 spacing is more compact and reads cleanly on screen, while double spacing is still required for some academic submissions and editorial review processes. Always check the style guide first.
Can I apply 1.5 spacing to only part of a document?
Yes. Select only the paragraphs you want to format, then apply 1.5 spacing using any of the three methods. The rest of the document keeps its original spacing.
How do I make 1.5 line spacing the default in Word?
On the Home tab, right-click the Normal style and choose Modify. Set line spacing to 1.5 lines, then tick New documents based on this template and click OK.
Does 1.5 line spacing work the same way in Word for Mac?
Yes. The Home tab dropdown and the Paragraph dialog box work identically on Mac. The keyboard shortcut on Mac is ⌘ + 5 instead of Ctrl + 5.
Should I use 1.5 line spacing or single spacing for a CV?
Single spacing is the standard for CVs because it keeps everything on one page. Use 1.5 line spacing for cover letters and supporting documents where readability matters more than page count.
