What superscript characters are
A superscript is a small character raised above the line, like the 2 in x² or a footnote marker¹. Word processors can raise any text with formatting, but the characters on this page are different: each one is its own Unicode character with the raised shape built in.
That is why they survive being pasted into Instagram bios, Discord, X posts, file names and other places that strip formatting. Use them for exponents (10⁶), units (m², cm³), footnote markers, ion charges (Ca²⁺) and ordinals like 1ˢᵗ.
Why some superscripts look mismatched
The digits came into Unicode in two batches. ¹ ² ³ belong to the old Latin-1 Supplement block (U+00B9, U+00B2 and U+00B3) because early Western character sets already had them. ⁰ and ⁴ to ⁹ live in a separate Superscripts and Subscripts block (U+2070 to U+2079). Many fonts draw both sets alike, but some do not, so a number like ¹⁴ can show digits of slightly different size or height.
The letters are borrowed from phonetic modifier letters, so the alphabet is incomplete: nearly every lowercase letter has a raised form, but several capitals do not. Generators fill the gaps with look-alikes, so check the result before you rely on it. To convert a whole phrase, try the small text generator.
How to type superscript
Windows has Alt codes only for the Latin-1 three: Alt + 0185 for ¹, Alt + 0178 for ², and Alt + 0179 for ³. For the rest, copy them here or, in Word, type the code (for example 2074 for ⁴) and press Alt + X.
For superscript formatting instead of special characters, press Ctrl + Shift + = in Word or Ctrl + . in Google Docs (Command + . on a Mac). In HTML, ¹, ² and ³ cover the first three digits, and the sup element raises anything else. In LaTeX, use a caret: x^{10}.
