Superscript & Subscript
Superscript characters sit above the line (² ³ ¹ ⁰ ⁴ to ⁹, ⁿ) and subscript characters sit below it (₀ to ₉). They are used for exponents (m², x³), chemical formulas (H₂O, CO₂), footnote marks and small notation.
Not every letter has a superscript or subscript form in Unicode, so you cannot turn any text into small raised text. Numbers, plus signs and parentheses are well covered, and only some letters are.
Practical Tips
- For units like m² or cm³, the special characters are handy in plain text. In formal documents or web pages, proper superscript formatting is often better.
- In chemistry, H₂O looks right with the subscript two (₂). Do not use a normal 2, which would read as part of the name.
- Search may not match H₂O with H2O. If people search for your term, write it the way they will type it.
- Screen readers may read these characters oddly. For important formulas, also write them out in words.

Frequently Asked Questions
Can I make any text small and raised?
No. Only numbers, a few symbols and some letters have superscript or subscript characters in Unicode.
How do I type m²?
Copy the superscript two (²) from this page. On many keyboards, Alt + 0178 on a Windows numeric keypad also works.
Is H₂O the same as H2O to a search engine?
Not exactly. Search may treat them as different strings. Use the form your readers will use.
