Outline Numbering in Word for macOS – Best Practices

Unlike most of my articles, this one is not a piece of original research. Shauna Kelly wrote the definitive method for producing outline numbering in Word several years ago. Unlike most of what you’ll read about techniques for creating numbering in Word, Shauna’s procedures actually work reliably. Unfortunately, Ms. Kelly passed away several years ago, though her web site has been kept going by volunteers. You can read her original posts here: How to create numbered headings or outline numbering in Word 2007 and Word 2010. My contribution is to document the steps needed to produce outline numbering in Word for macOS.

The names of some commands are different, or they’re found in a different place. I’m sticking to the step-by-step approach. For an in-depth explanation of why the steps work, please consult Shauna’s original pages. These instructions are quite specific. Please don’t include any steps not on the list below, or you’re on your own for the results.

Shauna argued strongly for using the built-in heading styles Headings 1 through 9. There’s nothing wrong with this and it can save a few steps. Sometimes, however, I prefer to save heading styles for headings and create a separate set of styles for numbering. In this article, I’ll translate Shauna’s classic method. The next post shows some optional variations: Outline Numbering Variations. If this is to be the basis for future documents, you want to be making these changes in a template. If you do this in a document and don’t apply the changes to the source template, you’ll have to redo all these steps for the next document or copy the styles using Word’s Organizer (Tools>Templates and Add-ins>Organizer in Word for Mac). Whenever you copy outline numbered sequences, you need to copy the styles that are linked (Headings 1 to 9 in this example) plus the List style (Numberings in this case).


Outline Numbering in Word for macOS – The Classic Method

Setting up the Styles

  1. Choose Format>Style and select Heading 1. (If you’re not already using Heading 1 in your document, change the List: dropdown to All styles)
  2. Click on the Modify button.
  3. Change the Style based on: dropdown from Normal to (no style) at the top of the list, then click on OK. While the dialog is open, choose Format>Paragraph and set the Left indent to 0 and the Special indent to (none). If there is any indenting, these will be set later. If you had already formatted Heading 1, you may need to make some changes after detaching it from Normal.
  4. Select Heading 2, click on Modify and change Style based on: to Heading 1. OK out.
  5. Repeat step 3 for each built-in Heading style, for as many levels of outline numbering as you require. Each style should be based on the one before.

Opening the Right Dialog Box

  1. In the Paragraph section of the Home tab, choose Multilevel List>Define New List Style. Avoid starting from Numbered List, that is not reliable.
    Multilevel List>Define New List Style in Word 2011 and 2016
    Outline Numbering in Word for OS X - Multilevel List 2011 (left) + 2016 (right)
  2. In the Define New List Style dialog, give your style a plural name like Headings or Numberings, since this will apply to several styles.
  3. Click on the Format button and choose Numbering.
  4. Set the style name and click on Format>Numbering in Word 2011
    Name + Numbering in Word 2011
    Word 2016 for Mac:
    Name + Numbering in Word 2016
  5. Now the Bullets and Numbering dialog opens, an extra step that doesn’t happen in Word for Windows. If you need straightforward legal-style numbering, there is a preset shown in the window that can save you many of the steps in the routine outlined below. Click on the Customize button.

Link a Paragraph Style to a List Style

  1. Finally we get to the Customize Outline Numbered List dialog. Once this dialog is open, we will leave it open until all levels are set up. Start by clicking on the dialog expander button to see all the options (circled in red):
    Word 2011:
    Customize Outline Numbered List in Word 2011
    Word 2016 for Mac:
    Customize Outline Numbered List in Word 2016
  2. Start by selecting 1 in the Level list.
  3. Next, we attach the paragraph style to the list style. Select Heading 1 in the Link level to style dropdown:
    Word 2011:
    Attach Paragraph Style to List Style in Word 2011
    Word 2016 for Mac:
    Attach Paragraph Style to List Style in Word 2016
  4. Now set the numbering for the style. In the Number format: (Word 2011) or Enter formatting for number: (Word 2016/2019) field, delete any content displayed. If the first outline numbering level starts with text, like Chapter 1 or Section 1, type in the text and a space.
  5. Using the Number style: (Word 2011) or Number style for this level: (Word 2016/2019) dropdown, choose the number appearance. Outline Numbering in Word for OS X has a quirk: the Level 1 choice is already displayed, even if no number appears in the Enter formatting for number: box. Just click on the dropdown and re-select the Level 1 that already appears selected and Word will do the right thing. A number appears in the Number format: or Enter formatting for number: field.
  6. Add any punctuation or symbol that is to follow the number.
  7. Set the Number position and Text position. Both numbers are the distance from the left margin. Left alignment for numbers is most common, but Roman numerals can look better right-aligned, since their width varies more. Normally the tab and indent are set for the same amount. The tab controls the position of the first line and the indent all the lines in the paragraph after that.

Repetition for All Levels (Legal-style Numbering)

Doing the rest of the levels involves repetitive steps that get a little longer with each level. Here are the steps for level 2:

  1. Select 2 from the Level list.
  2. Choose Heading 2 from the Link level to style: dropdown.
  3. Delete the contents of Number Format: (Word 2011) or Enter formatting for number: (Word 2016/2019).
  4. Set Previous level number: (Word 2011) or Include level from: (Word 2016/2019) to Level 1.
  5. Type a period.
  6. Click on the Number style: (Word 2011) or Number style for this level: (Word 2016/2019) dropdown and choose 1,2,3, ….
  7. Set the Number position and Text position.

So far, so good. Now let’s do level 3:

  1. Select 3 from the Level list.
  2. Choose Heading 3 from the Link level to style: dropdown.
  3. Delete the contents of Number Format: or Enter formatting for number:.
  4. Set Previous level number: or Include level from: to Level 1.
  5. Type a period.
  6. Set Previous level number: or Include level from: to Level 2.
  7. Type a period.
  8. Click on the Number style: or Number style for this level: dropdown and choose 1,2,3, ….
  9. Set the Number position and Text position.

Steps for Level 4:

  1. Select 4 from the Level list.
  2. Choose Heading 4 from the Link level to style: dropdown.
  3. Delete the contents of Number Format: or Enter formatting for number:.
  4. Set Previous level number: or Include level from: to Level 1.
  5. Type a period.
  6. Set Previous level number: or Include level from: to Level 2.
  7. Type a period.
  8. Set Previous level number: or Include level from: to Level 3.
  9. Type a period.
  10. Click on the Number style: or Number style for this level: dropdown and choose 1,2,3, ….
  11. Set the Number position and Text position.

Are you seeing the pattern? Each additional level repeats the previous steps and adds 2 new steps. By the time you get to level 9, you’ll have set the previous level and typed a period 8 times before setting the last number!


Editing Outline Numbering in Word for OS X

Like every good designer, you’ll probably want to tweak these styles later. For paragraph styling, like the amount of space before or after, you can simply modify the paragraph parameters. That’s easy. But anything to do with the numbering or its positioning relative to the paragraph should be done in the Outline Numbering dialog. Unfortunately, both Word 2011 and 2016 have a completely non-intuitive method for getting a list style into editing mode.

  1. In the Quick Style Gallery, right-click on Heading 1 and choose Modify Style.
  2. Click on the Format button and choose Numbering. The Bullets and Numbering dialog opens to the List Styles tab, where you can’t Add, Modify or Delete anything: the buttons are permanently disabled. Serious bug!

  3. Click on the Outline Numbered tab. None is highlighted, which is not helpful. Examine the tiles carefully, you have to choose the correct one. Since you have linked styles to levels, the tile you are looking for will show the first 3 of those style names, but then several other tiles will also show the heading names as well.
  4. Click on it the most likely suspect and see if the Reset button becomes enabled. That only happens with user-created list styles, so that’s an indication of the correct tile.
  5. Now click on the Customize button. This will only work if you are editing the outline numbering on the same installation of Word on which you originally created it. Open in a different installation or version and the Bullets and Numbering tiles do not show your custom list.
  6. Edit the numbering, then exit when you are finished. Instead of editing your named List Style, Word has created a new list style autonamed Current List1.

If you’re using a different installation of the program than what you created the list on, you can’t even use the Outline Numbered tab. All the tiles will display the stock numberings. Instead of editing your list style, you must start all over and get it right in one editing pass.

  1. Word for MacOS Sonoma 14.2 SUCKS. You provided instructions for Word in 2011 and 2016, but this is 2024 John, and most of it is useless. When will Microsoft get off their comfortable derrieres and develop a version that is reliable?
    I am tired of relying on YouTube for answers -that only work sometimes.

    Put on your BIG-BOY pants and fix this crap, PLEASE.

    • The steps in 2024 version of Word for Mac are exactly the same as what is published in the article, with the exception that “Multilevel List” is now called “Multi-level List”. The appearance of the dialogs has changed a little, but the command names are still the same.

      As always, if you have trouble implementing the information on your own, we are available to do it for you.
