How to format superscript and subscript in Word? Superscript and subscript are the two built-in formatting options that move selected text above or below the normal text line. They are useful for formulas, references, symbols, scientific terms, and technical writing.

The safest beginner method is to type the text normally first, select only the character that needs to move, and then apply Superscript or Subscript. This keeps the rest of the word, number, or formula unchanged.

What Is the Difference Between Superscript and Subscript? #

Superscript and subscript both change the vertical position of selected text, but they move text in opposite directions. Superscript raises text above the normal line. Subscript lowers text below the normal line.

Formatting type	What it does	Common examples
Superscript	Raises the selected character above the normal text line.	Footnote numbers, references, exponents, trademark symbols, and ordinal numbers.
Subscript	Lowers the selected character below the normal text line.	Chemical formulas, scientific notation, variable labels, and technical symbols.

How to Format Subscripts in Word #

Use subscript when a character should appear below the normal text line. This is common in chemical formulas such as H₂O, scientific notation, and technical labels where part of the text needs to be lowered.

Step 1: Select the character to lower. Click and drag over the number, letter, or symbol that should become subscript. Select only the character that needs to move, not the surrounding text.

Step 2: Use the Subscript button. Go to the Home tab. In the Font group, look for the two X buttons with small number twos next to them. Select the button where the small number appears at the bottom. This is the Subscript button.

Step 3: Check the result. The selected character is lowered below the normal text line. If only the intended character moved, the subscript formatting was applied correctly.

How to Format Superscript in Word #

Use superscript when a character should appear above the normal text line. This is common for footnote references, exponents, citations, ordinal numbers, and symbols such as trademark or copyright marks.

Step 1: Select the character to raise. Highlight the number, letter, or symbol that should appear above the regular text line.

Step 2: Use the Superscript button. Stay on the Home tab. In the Font group, select the X button where the small number appears at the top. This is the Superscript button.

Step 3: Review the formatting. The selected character is now raised above the normal text line. If more text was raised than expected, undo the change and select only the character that should be formatted.

How to Type Directly in Superscript or Subscript #

You can also turn on Superscript or Subscript before typing. Select the button first, type the small character, and then select the button again to turn it off.

How to Apply Superscript or Subscript to Multiple Places at Once #

If the same type of formatting is needed in several separate places, you can select multiple text parts before applying the button.

Step 1: Select the first character. Highlight the first number, letter, or symbol that needs superscript or subscript formatting.

Step 2: Add more separate selections. Press and hold Ctrl on your keyboard, then select the other characters you want to format.

Step 3: Apply the formatting once. After all required characters are selected, select Superscript or Subscript in the Font group. Word applies the formatting to every selected character at the same time.

How to Use the Font Dialog Box for Superscript and Subscript #

The buttons on the Home tab are the fastest method, but the Font dialog box gives another way to toggle superscript and subscript.

Step 1: Select the text. Highlight the character or text that needs to be raised or lowered.

Step 2: Open the Font dialog box. On the Home tab, go to the Font group and select the small dialog box launcher in the bottom-right corner of the group.

Step 3: Choose Superscript or Subscript. In the Font dialog box, turn on Superscript or Subscript, then select OK.

How OnStyle Helps with Formatting Consistency #

Superscript and subscript can also be accessed from the OnStyle tab. The Microsoft Word add-in places important formatting shortcuts on one tab so users can format documents faster, cleaner, and more consistently.

OnStyle also supports document validation. It can inspect Word documents with more than 150 checks, and in many cases, it can auto-fix the issues it finds. This is especially useful for long, technical, or regulated documents where small formatting mistakes can be difficult to find and fix manually.

In addition to quick and easy-to-use tools, OnStyle helps users apply standard formatting more efficiently and keep documents aligned with company, project, or industry requirements. This can reduce manual formatting work across styles, cross-references, links, hidden text, heading numbering, table formatting, and other document quality areas.

Common Mistakes to Avoid #

• Do not select too much text. If an entire word or phrase moves above or below the line, undo the change and select only the character that should be formatted.
• Do not leave the button turned on. If Superscript or Subscript stays active, the next text you type will continue as raised or lowered text.
• Do not fake superscript or subscript manually. Avoid making text smaller and moving it with spacing tricks. Use Word’s built-in Superscript and Subscript commands instead.
• Check formulas and references carefully. In scientific, technical, or regulated documents, a misplaced subscript or superscript can change meaning, so review these characters before finalizing the document.

Summary: How to Format Superscript and Subscript in Word #

Learning how to format superscript and subscript in Word is simple: select the character that needs to move, go to the Home tab, and use the Superscript or Subscript button in the Font group. For another method, open the Font dialog box from the Font group and toggle Superscript or Subscript there.

Use these built-in tools instead of manual spacing or font-size workarounds. Superscript and subscript keep raised and lowered characters easier to edit, easier to review, and more consistent throughout the document. For longer or more controlled documents, OnStyle can further support consistency by giving users quick access to common formatting tools and by validating technical and formatting issues across the document.
