Double Spacing in Word Doesn't Have to Be a Headache
I'm going to give you the straightforward steps to double space a document in Microsoft Word, but I'll also warn you about the one place where this breaks down and costs you about twenty minutes of headache. The basics are actually embedded in the Format menu. Select the text you want to double space or press Ctrl+A to select everything, then right-click and choose Paragraph. Under Spacing, change the After value from 0 pt to 12 pt. That's technically what double spacing is in Word's calculation model.
How To Do Double Spacing In Word Properly
Here's what most guides miss. There are two different ways to achieve double spacing and they don't always produce the same visual result. The method I just described—adjusting paragraph spacing with After set to 12 pt—adds space after every paragraph. The second method uses the Line Spacing dropdown in the same dialog box and sets it to Double. This tells Word to double the space between every individual line within the paragraph rather than between paragraphs. For academic papers, the Line Spacing set to Double method is what almost everyone wants. For reports where sections need breathing room, the 12 pt After spacing can look cleaner. One edge case that ruined my Tuesday last month: I was formatting a dissertation chapter where I had a table of contents generated via Styles, and the TOC was picking up the paragraph spacing I'd applied to the body text. Setting "Don't add space between paragraphs of the same style" in the Style settings fixed it, but finding that setting took longer than I'd like to admit.
The Shortcut You Should Know About
Ctrl+5 toggles double spacing on the selected text instantly. It's buried in the Line and Paragraph Spacing button on the Home tab, which shows up as five horizontal lines with an arrow pointing up and down next to them. If you're doing this regularly, using the shortcut saves you from clicking through menus every single time. There's also a keyboard-only path through the Ribbon. Press Alt+H, then L, then D. That hits Line Spacing Options and opens the Paragraph dialog directly, landing you at the Double option without touching the mouse.

Where People Go Wrong
Setting the spacing in the wrong place is the most common mistake. People go to the Paragraph dialog but click the Line Spacing dropdown and accidentally pick 1.5 instead of Double because the option list isn't sorted alphabetically and 1.5 Lines appears above Double when you have custom spacing options installed. Another issue: if your document has existing style modifications, changing the paragraph spacing manually won't override the underlying style. You'll think you've applied double spacing and then wonder why it reverts when you switch templates. The fix is modifying the style itself rather than the individual paragraph. Right-click Normal style, select Modify, and change the spacing there. A third thing to check before submitting anything formatted this way: make sure you haven't manually inserted extra paragraph breaks between lines. Some people hit Enter twice and then set double spacing, which doubles the spacing on top of the manual breaks and makes the document look like it's been set in open type. That doesn't show up in print preview immediately if you're reading on a screen at a zoomed-out view.
When Double Spacing Fails Completely
If you're working with a document that has columns, double spacing through the standard methods often misaligns or stretches the layout unpredictably. I ran into this once with a two-column newsletter layout and ended up adjusting the column spacing manually instead because Word's line spacing engine doesn't respect column boundaries the way you'd expect. Also, older versions of Word, particularly 2003 and earlier, handle double spacing differently due to their older layout engine. If you're collaborating with someone who uses a legacy version, test the output on their system before you send it out.
