How to Keep IEEE Reference Numbers Together Without Line Breaks in Word
Question details
The user needs to prevent IEEE citation reference numbers and their enclosing brackets from splitting across different lines at the page margin.

- Device & OS
- not provided
- Scenario
- Formatting an academic or technical document using the IEEE citation style, where multiple references are grouped together.
- Observed behavior
- The reference bracket and numbers are breaking across lines, appearing separated (e.g., [1 on one line and 3] on the next). Adding a regular space does not correct the issue.
Ensure you have completed most of your text editing and layout adjustments, as line breaks naturally shift as you type or change page margins.
Use a Non-Breaking Space Inside the Reference
Replace the standard space inside the brackets with a non-breaking space to glue the numbers and brackets together, preventing them from wrapping to the next line.
Word processors treat standard spaces as permissible line-break points. By substituting a regular space with a non-breaking space, you force the application to keep the adjacent characters together on the same line.
Find the specific IEEE reference in your document that is breaking across two lines (for example, between the numbers 1 and 3).
Place your text cursor right after the first number or comma, and delete the existing standard space that separates it from the next number.
Press the keyboard shortcut 'Ctrl + Shift + Space' (on Windows) or 'Cmd + Shift + Space' (on Mac). The numbers and brackets will immediately snap together on the same line.

Inspect Hidden Formatting Marks
Turn on formatting marks to visually identify hidden spaces, line breaks, or field-code anomalies inside your reference brackets.
Check Citation Field Codes
If your IEEE references are generated by a citation manager plugin, check the raw field code for incorrect spacing parameters.
Format Academic Papers Flawlessly with WPS Writer
Easily manage IEEE references, citations, and complex academic formatting without frustrating line breaks using WPS Writer.
- 1. Open your academic document: Launch WPS Writer and open the document containing your IEEE references.
- 2. Locate the citation: Place your cursor exactly where the space should be within the IEEE reference brackets.
- 3. Apply a non-breaking space: Press 'Ctrl + Shift + Space' to insert a non-breaking space, ensuring the numbers never break across lines.
- 4. Verify with editing marks: Go to the 'Home' tab and click the 'Show/Hide Editing Marks' icon to verify your formatting is correct.

Frequently Asked Questions
Why do my IEEE references break across lines even when they are linked?
By default, word processors treat regular spaces or hyphens inside brackets as permissible line-break points. The text will wrap to the next line to maintain margin alignment unless it is explicitly constrained by non-breaking characters.
How do I keep a hyphenated reference like [1-3] together?
To prevent line breaks at a hyphen, you need to replace the standard hyphen with a non-breaking hyphen. You can do this by selecting the hyphen and pressing 'Ctrl + Shift + Hyphen' (or Cmd + Shift + Hyphen on a Mac).
Will updating my bibliography override my manual non-breaking spaces?
Yes, if you are using an automated reference manager plugin. Manually altering the citation text in the document might be overwritten when the bibliography refreshes. In such cases, it is recommended to adjust the formatting directly in the output style settings of your reference manager software.
