The List Formatting Hijack
Google Docs tries to be intelligent when it comes to document structuring. If you create a numbered list (1, 2, 3), and then press Tab or use the “Increase indent” button to create a sub-list underneath one of the items, Docs automatically changes the formatting of that indented list. By default, it often switches from standard Arabic numerals (1, 2, 3) to letters (a, b, c), and if you indent further, it will aggressively switch to Roman numerals (i, ii, iii, iv).
This automated hierarchical styling is perfect for creating standard academic outlines or legal documents. However, if you are writing a technical manual, a step-by-step tutorial, or a specific data schema where you *need* the sub-list to remain as standard numbers (e.g., you want the structure to be 1, then 1.1, 1.2, rather than 1, then a, b, or i, ii), Google Docs will fight you every step of the way. It will constantly force the Roman numerals upon you, breaking your intended format. If you require strict control over exactly how your nested lists are presented, you must intervene manually, as there is no global “off” switch for this behavior.
How to Force Standard Numbers on Sub-Lists
Because Google Docs does not have a master setting to disable this specific behavior, you must manually override the formatting of the indented list.
- Create your standard numbered list (1, 2, 3) in Google Docs.
- Press Enter to create a new line, then press Tab to indent it and create a sub-list. (Notice Docs changes it to ‘a’ or ‘i’).
- Click directly on the letter or Roman numeral itself so that it becomes highlighted in blue.
- Right-click on the highlighted numeral.
- From the context menu that appears, hover over the option that displays a preview of your list format (it usually looks like a small box with 1, a, i inside).
- A secondary menu will slide out showing all available list styles. Click on the style that uses standard numbers (1, 2, 3) at all indentation levels (usually the top-left or top-middle option).
Google Docs will override its default behavior and force that specific sub-list to use standard numbers instead of Roman numerals. You may need to repeat this process if you create deeply nested lists in a new section of the document.
