How to Create a 0.5-Inch First Line Indent in Word (Windows, Mac, Web)

To create a 0.5-inch first-line indent in Word, select your paragraphs, open the Paragraph dialog box, and on the Indents and Spacing tab set Special to First line and By to 0.5″. Select OK, and the first line of each selected paragraph moves in half an inch while the other lines stay at the margin.

This is more reliable than pressing Tab, because the indent becomes part of the paragraph’s formatting and stays exact when you edit, copy, or reflow text. Below you’ll find the steps for Word on Windows, Mac, and the web, plus the ruler method and how to make the indent the default for every document.

Quick Answer

1. Select the paragraphs (press Ctrl + A for the whole document).
2. On the Home tab, select the small launcher arrow in the corner of the Paragraph group. On a Mac, choose Format > Paragraph.
3. On the Indents and Spacing tab, under Indentation, set Special to First line.
4. Type 0.5″ in the By box.
5. Select OK.

Before You Start

This guide covers Word for Microsoft 365, Word 2024, 2021, 2019, and 2016 on Windows and Mac, and Word for the web, as of September 2026.

A first-line indent moves only the first line of a paragraph in from the left margin. It’s the standard look for essays, novels, and many school style guides, including MLA and APA body text, which usually call for a half-inch indent. It’s the opposite of a hanging indent, where the first line stays at the margin and the rest of the lines move in. If you need that instead, see our guide to creating a hanging indent in Word.

Word measures indents in the units set on your computer. In the US that’s usually inches, so you type 0.5″. If your Word shows centimeters, 0.5 inch is 1.27 cm, and you can type 0.5″ anyway; Word converts it for you. Our guide to changing inches to cm in Word explains how to switch units.

How to Set a 0.5-Inch First-Line Indent in Word for Windows

1. Select the text. Click in a single paragraph, drag across several, or press Ctrl + A to select the whole document. Expected result: the text is highlighted.
2. Open the Paragraph dialog box. On the Home tab, find the Paragraph group and select the small arrow (the dialog box launcher) in its lower-right corner. In most versions you can also right-click the selected text and choose Paragraph.
3. Go to Indents and Spacing. Select the Indents and Spacing tab if it isn’t already showing.
4. Set Special to First line. Under Indentation, open the Special list and select First line.
5. Enter 0.5 in the By box. Type 0.5″ in By, or use the arrows to reach it. Leave Left and Right at 0 unless you want the whole paragraph moved in.
6. Check the Preview. The Preview box at the bottom of the dialog shows how the paragraph will look.
7. Select OK. Expected result: the first line of every selected paragraph starts half an inch from the margin, and new paragraphs you start by pressing Enter keep the same indent.

The Special list has three choices: None removes the special indent, First line indents just the first line, and Hanging indents every line except the first. Microsoft’s Adjust indents and spacing page describes each setting.

If the dialog also has a Set As Default button, it saves the current paragraph settings as the default for new documents. The Normal style method below does the same job with more control.

How to Set a First-Line Indent in Word for Mac

1. Select the paragraphs you want to indent, or press Command + A for the whole document.
2. Open Paragraph settings. On the menu bar, select Format > Paragraph. Expected result: the Paragraph dialog opens.
3. Select the Indents and Spacing tab.
4. Set Special to First line. Under Indentation, choose First line from the Special list.
5. Type 0.5″ in By.
6. Select OK. Expected result: the first line of each selected paragraph moves in half an inch.

The Mac dialog uses the same labels as Windows. The only difference is how you open it: from the Format menu rather than a launcher on the ribbon.

How to Indent the First Line in Word for the Web

Word for the web (Word in a browser at office.com) has fewer paragraph controls. Microsoft’s instructions for the web use the Tab key:

1. Click at the very start of the first line of the paragraph.
2. Press Tab. Expected result: the first line moves in. By default, the tab distance is half an inch.
3. Keep typing. When you press Enter at the end of a paragraph that has a first-line indent, Word formats the next paragraph the same way.

Some versions of Word for the web also include paragraph options, for example through the Line and Paragraph Spacing button on the Home tab, where you may find an Indentation section with a Special setting. Menus in the web app change often, so if you don’t see it, use the Tab method. For exact control, select Editing > Open in Desktop App (labels vary) and follow the Windows or Mac steps. See Microsoft’s Create a first line indent page for the web.

How to Set a First-Line Indent with the Ruler

The ruler is handy when you want to see the indent as you set it, though it’s harder to land exactly on 0.5 inch.

1. Show the ruler. On the View tab, select the Ruler check box.
2. Select the paragraphs you want to change.
3. Find the first-line marker. At the left end of the ruler, there are two triangles and a small square. The top triangle (pointing down) is the first-line indent. The bottom triangle is the hanging indent, and the square moves the whole paragraph.
4. Drag the top triangle to the 0.5 mark. Expected result: only the first line of each selected paragraph moves.

Tip: hold Alt (Windows) or Option (Mac) while dragging to see exact measurements on the ruler in many versions. To check the value precisely, open the Paragraph dialog afterward and confirm By reads 0.5″. Microsoft’s Using the ruler in Word page shows each marker.

How to Make a 0.5-Inch First-Line Indent the Default

If every body paragraph in your document should be indented, change the Normal style, which most body text uses. Every paragraph in that style updates at once.

1. Open the style settings. On the Home tab, in the Styles gallery, right-click Normal and select Modify.
2. Open paragraph formatting. In the Modify Style dialog, select Format > Paragraph.
3. Set the indent. On Indents and Spacing, under Indentation, choose First line in Special and type 0.5″ in By. Select OK.
4. Choose where it applies. Select Only in this document to change this file, or New documents based on this template to use the indent in every new blank document.
5. Select OK. Expected result: every paragraph using the Normal style now has a half-inch first-line indent.

Before you choose New documents based on this template: it changes the Normal template, which affects all your future blank documents. If you only need the indent for one assignment, keep it to this document.

Headings, titles, and block quotes usually use other styles, so they won’t be indented. That’s normally what you want.

Which Method Should You Use?

Situation	Best method	Why
A few paragraphs, exact 0.5 inch	Paragraph dialog	Precise and quick
Whole essay or manuscript	Normal style	Every body paragraph updates at once
Quick visual adjustment	Ruler	See the change as you drag
Working in a browser	Tab key, or open in the desktop app	Fewer controls on the web

Troubleshooting

Pressing Tab adds a tab character instead of an indent

Desktop Word can turn a Tab at the start of a paragraph into a first-line indent through an AutoCorrect setting, but it isn’t always on. For consistent results, use the Paragraph dialog instead of Tab.

Some paragraphs didn’t change

They may use a different style or have their own indent settings. Select them and apply the Paragraph dialog steps again, or apply the Normal style to them.

The whole paragraph moved, not just the first line

You changed the Left indent or dragged the square on the ruler. Set Left back to 0, and use Special > First line instead. Our guide on removing indents in Word can help reset things.

The By box shows cm instead of inches

Type 0.5″ with the inch mark and Word converts it, or enter 1.27 cm. To switch units permanently on Windows, look for Show measurements in units of under File > Options > Advanced.

Bulleted or numbered lists look wrong

Lists have their own indent settings. Apply the first-line indent to body paragraphs only, and adjust list indents separately.

Frequently Asked Questions

Is a first-line indent the same as pressing Tab?

They look similar, but a first-line indent is paragraph formatting that stays exact, while Tab inserts a character. The indent is more reliable for long documents.

What is 0.5 inch in centimeters?

0.5 inch is 1.27 cm.

Does MLA or APA require a 0.5-inch first-line indent?

Both styles typically call for body paragraphs indented half an inch. Always check your instructor’s or publisher’s specific rules.

How do I indent the first line of every paragraph at once?

Press Ctrl + A (Command + A on a Mac) and apply the Paragraph dialog steps, or modify the Normal style.

How do I remove a first-line indent?

Select the paragraphs, open the Paragraph dialog, and set Special to None.

Can I set a first-line indent on the Word mobile app?

The mobile apps have limited paragraph controls, and options vary by version. For a precise 0.5-inch indent, use Word on a computer.
