How it works

The squared symbol is ², Superscript two, U+00B2. Alt+253 and Alt+0178 both type it on a number pad. The rows add the cubed sign ³, ready-made x² and m², and unit characters such as ㎡.

The squared symbol on a keyboard

The U.S. layout has no key for ² and no Option key. The French layout has a ² key left of the 1, and the German and Dutch layouts type it with AltGr and 2. On a number pad, Alt+253 or Alt+0178 types it. With a Compose key, press Compose, ^, then 2. Where none of these works, the typed stand-in is ^2.

Square units in one character

Unicode has ㎟, ㎠, ㎡, ㎢, ㎨, ㎯ as single characters, for square millimeters, centimeters, meters and kilometers and for two units per second squared. Each is defined as its letters and a ² set in one square, so ㎡ and m² say the same thing.

Cubed is ³, Alt+0179. It has no short code.
The 2 of H₂O is a subscript, ₂, which is a different character.

Questions and answers

How do you type the squared symbol on a keyboard?

Hold Alt and type 253, or 0178, on the number pad, then let go. On a keyboard with a Compose key, press Compose, ^, then 2. Anywhere else, copy ² from this page.

What is the alt code for squared?

Alt+253. The squared sign also has a four-digit code, Alt+0178. Both type ², U+00B2, and both need the number pad.

Is there an alt code for superscript 2 and superscript 3?

Superscript 2 has two, Alt+253 and Alt+0178. Superscript 3 has one, Alt+0179. The raised 4 to 9 have none, and the raised n is Alt+252.

What is the HTML code for the squared symbol?

² draws ², and ³ draws ³. By number, ² is ² or ².

How this list was compiled: Names, and the code points they belong to, are from UnicodeData.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/UnicodeData.txt), printed in sentence case. Other names, notes and cross-references are from NamesList.txt of the same version (https://www.unicode.org/Public/18.0.0/ucd/NamesList.txt); the version a character was added in is from DerivedAge.txt (https://www.unicode.org/Public/18.0.0/ucd/DerivedAge.txt), and the years are from https://www.unicode.org/history/publicationdates.html. Alt codes are from the code page 437 table (https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/PC/CP437.TXT) and the code page 1252 table (https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP1252.TXT). Option keys are those of the U.S. keyboard layout as the Unicode CLDR project records it (https://github.com/unicode-org/cldr/blob/release-42/keyboards/osx/en-t-k0-osx.xml); other layouts differ. HTML entity names are from https://html.spec.whatwg.org/entities.json. LaTeX commands are listed only when LaTeX's own fontdef.dtx or ltoutenc.dtx (https://github.com/latex3/latex2e/tree/develop/base) defines them. A cell is empty where no such method exists. Compose sequences are from the X.org en_US.UTF-8 Compose file (https://gitlab.freedesktop.org/xorg/lib/libx11/-/blob/master/nls/en_US.UTF-8/Compose.pre). The unit characters are the characters of the CJK Compatibility block whose Unicode name ends in SQUARED or CUBED, found by a search of UnicodeData.txt; what each is made of is its decomposition field in that file. Two more, the square and cubic decimeter (U+3378 and U+3379), were added later, in Unicode 4.0 (2003), and are left out: a device without a font for them draws an empty box. Which layouts carry the raised 2 on a key is read from the layout records of the Unicode CLDR project (https://github.com/unicode-org/cldr/tree/release-42/keyboards/windows: the French, German, Dutch and US files).
