How do I type the infinity symbol?

The fastest way is to copy it: ∞. On Windows, hold Alt and type 236 on the numeric keypad, or use Alt+X after typing 221E. On Mac, press Option + 5. On phones, paste ∞ or search "infinity symbol" and copy it.

How do I type ∞ on an iPhone or Android?

Phones don't have ∞ on the standard keyboard, so the easiest path is to copy it once and paste it where you need it. On iPhone you can also save ∞ as a text replacement (Settings → General → Keyboard → Text Replacement) so a shortcut like "inf" expands to the symbol.

How do I draw the infinity symbol?

Draw it in one smooth motion, like a sideways figure eight: start in the middle, loop up and around to the right, come back through the center, then loop up and around to the left and close it. One continuous line, no lifting the pen — that unbroken stroke is the whole point.

Keyboard shortcuts, by device

Type ∞ directly

Mac — press Option + 5.
Windows — hold Alt and type 236 on the number pad; or type 221E then Alt + X in Word.
iPhone / iPad — copy it once, or add a Text Replacement (Settings → General → Keyboard) so “inf8” becomes ∞.
Android — long-press in some keyboards, or search “infinity” in Gboard’s symbol panel.
Google Docs — Insert → Special characters → search “infinity”.
HTML / web — write ∞ or ∞.

How to draw the infinity symbol by hand

The ∞ is one of the most satisfying shapes to draw because it is a single unbroken stroke. Start in the middle, sweep up and around to the left and back to the center, then up and around to the right and back — like writing a sideways number 8 without lifting your pen. End where you began. That return-to-the-start is the whole meaning of the symbol.

Draw it cleanly

Start at the center crossing point.
Loop up-left, down, and back to center.
Loop up-right, down, and back to center.
Keep the two loops even — or do not; a hand-drawn ∞ has its own soul.

The math behind it

In mathematics the symbol is called the lemniscate, introduced by John Wallis in 1655 to mean “without bound.” If you want that story, read the history of the infinity symbol and the great theories of infinity.

The infinity loop captured in soft, layered light — Infinite Soldier ∞ Collection.

A symbol you can make in one stroke, that means a thing with no end. That is not a coincidence — it is the point.∞

Now that you can make it anywhere, make it mean something. Every time you write ∞, you write the shortest possible reminder that there is no ceiling on your life. That is the whole idea behind Infinite Soldier — and you are already fluent in our alphabet.
