You can create headings in Microsoft Word documents by applying Word’s built-in heading styles (such as Heading 1 or Heading 2). After you have applied styles, you can modify them and change the font, size, color, and other formatting attributes so the entire document will update. Once you have applied heading styles, you’ll be able to navigate to the headings using the Navigation Pane and create a table of contents.

Heading styles are very important because they create structure in your documents and are readable by screen readers or assistive technology programs used by people with vision impairments. They can also save you a lot of time formatting and reformatting documents.

In addition to creating structure, heading styles are also used to:

• Generate a table of contents
• Reformat a document using Style Sets
• Navigate using the Navigation Pane (select Navigation Pane on the View tab in the Ribbon)
• Rearrange a document using the Outline View
• Create a structured PDF (portable document format) file with heading tags

Creating headings by applying Word heading styles

To create or designate headings, you will need to apply the built-in heading styles in order (Heading 1, Heading 2, Heading 3, and so) to paragraphs. There are 9 levels of headings available in Word.

Heading styles are technically available as paragraph and character styles, but it’s important to apply them as paragraph styles to entire paragraphs. A paragraph in Word is anything with a hard return after it (you have pressed Return or Enter).

Heading styles are affected by your theme choices (overall theme, color theme, and font theme). You can change theme options using the Design tab in the Ribbon.

To create headings by applying heading styles:

1. Click in the paragraph (title or subheading) you want to designate or format as a heading.
2. Click the Home tab in the Ribbon.
3. Click the heading style you want in the Styles Gallery (such as Heading 1) in the Style group. You may need to click the More arrow on the bottom right of the Styles Gallery to view more styles and then click the style you want to use.

All available heading styles do not appear initially in the Styles Gallery. When you apply a heading level (such as Heading 3), an additional heading level should appear in the Gallery (such as Heading 4).

The Styles Gallery appears on the Home tab in the Ribbon and typically displays top level headings:

If you click the More arrow on the bottom right of the Styles Gallery, an expanded gallery appears:

Modifying or customizing heading styles using the Styles task pane

If you modify heading styles, every instance of the modified style will change in your document. Not only will this save time, but it will also ensure consistency. There are many ways to customize heading styles in Word. In this article, we will modify heading styles using the Styles task pane.

The Styles task pane appears with styles in the document (you can change this display by clicking Options at the bottom of the task pane):

To modify or customize a heading style:

1. Click the Home tab in the Ribbon.
2. Click the dialog box launcher (diagonal arrow) on the bottom right in the Styles group. You can also press Ctrl + Alt + Shift + S. The Styles task pane will appear. If the task pane is floating, double-click the title bar.
3. Click in a paragraph using the style you want to modify.
4. Click the arrow to the right of the heading you want to modify in the Styles task pane and then select Modify from the drop-down menu. You can also right-click the heading style in the task pane and select Modify. A dialog box appears.
5. In the Modify Style dialog box, select the desired options such as font, font size, font color, alignment, and line spacing. Buttons in this dialog box are comparable to those in the Ribbon.
6. If you want to change some other formatting options (such as paragraph formats), select Format at the bottom of the dialog box and select other options from the drop-down menu.
7. Select Only in this document so that the style is modified in the current document only.
8. Do not select Automatically Update unless you want the document styles to update when a user changes heading formatting in the document. It’s typically best to leave this option unchecked.
9. Click OK or press Enter. The entire document will change unless a heading has been manually formatted (which overrides the style). You can simply reapply the style if this occurs.

The Modify Styles dialog box displays the style name, the type of style and options for modifying the style:

When you save the document, the modified styles are also saved.

Styles are the most important formatting feature in Word to automate formatting in longer documents. Heading styles also have the added benefit of creating structured documents and are integrated with several other Word features such as generated tables of contents.

Style is essential to making a strong first impression. Admittedly, this usually applies to fashion rather than formatting. But in the academic realm, you’ll win more points for applying clear and consistent heading styles in a document than for wearing a fancy outfit.

And since a well-formatted document is vital for clarity as well as grabbing the reader’s attention, today we’re taking a look at how to apply heading styles in Microsoft Word.

Using Headings

The ‘Headings’ styles in Microsoft Word are formatting options for making headings and subheadings stand out from the other text in your essay. This will help your reader, particularly in longer essays, by clearly indicating where different sections begin and end.

Microsoft Word actually comes with a number of default heading styles (named ‘Heading 1’ through to ‘Heading 9’). You can use these as you find them, but you may also need to change them to fit with any specific requirements for headings set out in your style guide.

But how should you use these headings? Like so:

1. Go to the ‘Styles’ section of the ‘Home’ tab on the main ribbon
2. Select the text you’re using as a heading and click on the appropriate ‘Heading’ style (e.g. ‘Heading 1’, ‘Heading 2’, etc.)
3. If the required style is not visible in the ‘Styles’ tab, click the little arrow in the bottom right to open a side menu with further options
4. If the required ‘Style’ still isn’t visible, click ‘Options…’ in the side menu and make sure ‘All styles’ is selected under ‘Select Styles to Show’, then click OK
5. Once the correct heading styles show in the menu, select the text you want to format and apply each heading and subheading accordinglyBe sure to use different styles to distinguish between different ‘levels’ of heading, since the formatting style of chapter titles should be distinct from those used for section or subsection headings: e.g. use ‘Heading 1’ for the main headings, then ‘Heading 2’ for the next level down, and ‘Heading 3’ for subsections, etc., being careful to apply each style consistently.

Numbered Headings

If you want to use numbered headings, Microsoft Word’s multilevel list options are very useful. This will apply numbering to titles and subtitles whenever a ‘Heading’ style is used, thereby ensuring clear and consistent numbering for all headings in your document.
To do this, you’ll need to:

1. Apply different heading styles to your document for each level of heading
2. Click on the ‘Multilevel List’ button in the ‘Paragraph’ section of the ‘Home’ tab
3. Select one of the list styles that refers to headings

This will apply a different numbering level to each heading style, while you can also modify and create multilevel list styles via the ‘Multilevel List’ menu.

This numbering will also update automatically if you add or remove headings, saving you the effort of re-numbering headings manually.

working on a solution based on a recent response to another thread i was involved in.

Here are two options to solve the initial question i raised in the thread (first option is a quick reset, second option retains your current styles but allows you to add old ones back in):

Solution 1. Home Tab—>Styles—>Change Styles—>Styles Set—>Reset Document Quick Styles

This will reset the styles to whatever they were when the document was first created, which is fine for some cases but did not work for me because I had saved new document titles, so it only reverted to a previous set and not the original set.

Solution 2. Home Tab—>Styles—>Full Styles Window (accessed by clicking the little arrow at the bottom right of the styles menu)—>Options—>

Select «Show all Styles» and Sort Alphabetically to make it easier to locate your style. Then return to the Style Manager window, click the down arrow next to a given style, and choose Add to Quick Style Gallery.

This works and is a nice solution because you can keep your current styles and retrieve some older ones without having to completely reset them. This provides you with more flexibility and control than Solution 1.

Note: In Solution 1 or 2, you might not see all of the styles that you reverted to or added into the Quick Style gallery, which might make you think that it has «not worked» as I originally thought. To show the styles after adding them back into the Quick Styles menu, go to

Home Tab—>Styles—>Full Styles Window (accessed by clicking the little arrow at the bottom right of the styles menu)—>Manage Styles (one of the three small icons at the bottom of the Style Manager window)

In the new window that pops up, it is probably easiest to sort the list alphabetically, then scroll to the heading you want to show in the Quick Styles menu, and if it is grayed out with a note that says «hide until used,» select it and choose «Show» (button located at the bottom of the current window).

Thanks to anyone who worked on this, and I hope the information is helpful to someone else in the future.
