Windows: hold Alt and type the number on the numeric keypad with Num Lock on; a dash means there is no Alt code that works the same on every Windows. Word for Windows: type the code, then press Alt+X. Mac, U.S. keyboard layout: ⌥ is Option and ⇧ is Shift; for the rest, Control+Command+Space opens the Character Viewer. HTML: paste the code into the page source.
How to use infinity symbols
The infinity sign ∞ is one character, U+221E, from the Mathematical Operators block — the sideways eight that John Wallis first used for infinity in 1655. ♾ is a different character: the “permanent paper sign”, which became the infinity emoji ♾️, so it looks different on every phone. ⧜ ⧝ ⧞ are rarer variants from mathematics: an incomplete infinity, a tie over infinity and infinity negated with a vertical bar.
In bios and tattoos ∞ usually means forever, and it is often paired with a heart — ♡ ∞ ♡ or ∞♡∞ — or put between two initials, L ∞ M. In maths it marks limits and intervals: x → ∞, −∞ < x < +∞. In set theory ℵ and ℶ, aleph and beth, name the sizes of infinite sets: ℵ₀, Georg Cantor’s notation, is the size of the set of natural numbers.
On a Mac, ∞ has its own shortcut, ⌥5; in Word, type 221E and press Alt+X. More maths symbols are on the math symbols page, and hearts to pair with ∞ are on the heart symbols page.
Questions
How do I type the infinity symbol ∞?
On a Mac, press ⌥5 (Option + 5). In Word, type 221E and press Alt+X. On iPhone and Android there is no ∞ on the keyboard: copy it from this page, or use the ♾️ emoji from the emoji keyboard.
What is the difference between ∞ and ♾️?
∞ is the maths sign and takes the colour of your text. ♾️ is an emoji — in Unicode it is the “permanent paper sign” — so it comes in colour and looks different on every phone.
What does the infinity symbol mean?
Endless, without limit. In bios and tattoos it usually means forever and is often paired with a heart: ♡ ∞ ♡. In maths ∞ is not a number but a size or a direction without end, as in x → ∞.
