Technical Report Word Numbering Template
The Technical Report template uses ISO 2145-style decimal numbering — 1, 1.1, 1.1.1, without trailing punctuation — with sans-serif Arial headings. It is the format commonly used in engineering specifications, system design documents, and software documentation.
All nine levels are linked to Word's built-in Heading 1–9 styles, so sections number and renumber automatically as you add, remove, or reorganize headings.

Numbering Structure
All nine levels are linked to Word's built-in Heading styles: apply Heading 1 and level 1 numbering appears, Heading 2 and level 2 appears, and so on. Numbering is followed by a single space — no stray tab jumps.
| Level | Linked style | Number format |
|---|---|---|
| 1 | Heading 1 | 1 |
| 2 | Heading 2 | 1.1 |
| 3 | Heading 3 | 1.1.1 |
| 4 | Heading 4 | 1.1.1.1 |
| 5 | Heading 5 | 1.1.1.1.1 |
| 6 | Heading 6 | 1.1.1.1.1.1 |
| 7 | Heading 7 | 1.1.1.1.1.1.1 |
| 8 | Heading 8 | 1.1.1.1.1.1.1.1 |
| 9 | Heading 9 | 1.1.1.1.1.1.1.1.1 |
Fonts: Arial headings (Latin text); theme default body font · Indent: 0.25 in per level, hanging indent
Who This Template Is For
- Engineering specifications and design documents
- System and software documentation
- Technical reports that follow ISO-style section numbering
In practice: "1 Introduction", then "1.1 Background", then "1.1.1 Scope" — clean decimal depth without dots after the numbers, rendered by the Heading styles automatically.
How It Works in Word
Double-click the .dotx and Word opens a new, unnamed document based on the template. Type a heading, apply a Heading style from the Styles gallery, and the number appears. Add, delete, move, or promote headings — the numbering re-calculates itself, because it is defined inside the style, not typed into the text.
Save your finished document as .docx and the numbering stays with it. Works on Word for Microsoft 365, Word 2024/2021/2019/2016, Word for Mac, and WPS Office.
