Infinity Symbols

Seven characters stand for one idea: the plain ∞, the emoji ♾, the notation variants ⧜ ⧝ ⧞ and the lookalike letters Ꝏ ꝏ. Click one to take it — ∞ is the one for a sentence, since it holds your text colour and size.

Copy and Paste Infinity Symbols

Seven characters, one meaning. Choose ∞ or any of its variants above and a single click copies it; paste with Ctrl+V or Cmd+V into whatever you are writing. Because it is a character and not a graphic, it will sit inside a tattoo mock-up, a wedding caption, a maths expression or a username without any of them treating it as an image.

What Are Infinity Symbols?

The infinity symbol is a lemniscate — a figure-eight curve with no start and no end. The English mathematician John Wallis introduced it for "boundless" in 1655, and it has symbolized the same idea ever since. In mathematics the concept of infinity is treated as a limit rather than a number, which is why ∞ behaves unlike the digits around it; everywhere else the character simply means forever.

This page carries all 7 Unicode forms of it, and they are not interchangeable. ∞ (U+221E) is the plain character and the one to reach for by default — it inherits your text colour and weight, so it drops into a sentence unnoticed. ♾ (U+267E) is the character behind the ♾️ shown in emoji keyboards; copied from here it pastes as plain text, while an emoji keyboard adds a variation selector that tells the platform to draw it in colour. ⧜ ⧝ ⧞ are mathematical variants — incomplete infinity, tie-over infinity, and infinity negated with a vertical bar — precise notation rather than ornament, and the least widely supported characters here. Ꝏ and ꝏ (U+A74E, U+A74F) are not infinity signs at all: they are Latin letters from Middle Welsh orthography that happen to resemble one, borrowed constantly for usernames because they read as infinity while sorting and searching as text.

Infinity Symbols Under Other Names

Searchers arrive here using five different words for the same character. All of them mean ∞:

• Forever sign or forever symbol — the most common non-mathematical name.
• Eternity symbol — the same character, usually in a memorial or romantic setting.
• Endless, unlimited or limitless sign — ∞ again, standing in for an infinite quantity, typically in branding copy.
• Lemniscate — the formal name for the curve itself.
• Sideways eight — what people call it when none of the above comes to mind.

There is no separate glyph for any of them. If you came looking for a forever symbol, ∞ is the character you want.

How to Use Infinity Symbols

Copying Infinity Symbols

Click the form you need from the grid. It goes straight to the clipboard.

Pasting Infinity Symbols into Apps

Any text field accepts it — profile names, captions, notes, formulas, form inputs. Nothing is converted or resized on the way in.

Combining Infinity Symbols with Hearts

The most-requested combination is an infinity heart, and Unicode has no single character for it. What people build is ∞ placed beside a heart taken from the heart symbols page: ∞♥, ♥∞♥ and ∞ 💖 are the usual arrangements.

Best Uses for Infinity Symbols

Infinity Symbols in Bios and Usernames

∞ says endless in one character, where the word itself would eat a quarter of the field.

Infinity Symbols in Tattoo Designs

Paste ∞ into a note beside a name or a date to see how the pairing sits before anything becomes permanent.

Infinity Symbols in Vows and Captions

A bare ∞ carries forever without spelling it out, which is usually the point.

Infinity Symbols in Mathematics and Engineering

As a limit, an unbounded interval, or a stand-in for "no maximum" in a specification — the mathematical uses the character was invented for.

Infinity Symbols in Interfaces

Unlimited plans, endless scroll and no-cap settings all use it as shorthand for an infinite allowance.

Getting Infinity Symbols Right

• Prefer ∞ in prose: it inherits your text colour, while ♾ may render as a coloured emoji and shift the line height.
• Never use ⧞ decoratively: the vertical bar is a negation, so in notation it means the opposite of infinity.
• Ꝏ is a letter: useful in a username, wrong in a formula.
• Give it room: "love ∞ always" scans better than "love∞always".
• Accessibility: a pasted ∞ is announced as "infinity" — fine once, tiring when repeated as decoration.

Infinity Symbols Unicode Names and Codes

Unlike most characters on this site, ∞ has a direct keyboard route on every desktop platform:

• Windows: Alt+236 on the numeric keypad, or Alt+8734 for the same character by its decimal code point.
• Mac: Option+5 types ∞ outright — no character viewer required.
• Linux: Ctrl+Shift+U, then 221e, then Enter or Space.
• Code point: ∞ is U+221E. Typing 221e and pressing Alt+X converts it in place in many editors.
• HTML: ∞ renders ∞.
• Phones: there is no ∞ key on the stock iOS or Android keyboard. The emoji keyboard carries ♾️ under Symbols; for the plain character, copying is the only practical route.

Frequently Asked Questions About Infinity Symbols

What is the difference between ∞ and ♾?

∞ is a mathematical character that takes the colour and size of your text. ♾ is the character behind the infinity emoji, so many platforms draw it larger and in colour. For a sentence, use ∞.

Is there a forever symbol that is not the infinity symbol?

No. "Forever symbol", "eternity symbol" and "endless sign" all refer to ∞. There is no separate Unicode character for any of them.

How do I type the infinity symbol on a keyboard?

Alt+236 or Alt+8734 on Windows with the numeric keypad, Option+5 on Mac, Ctrl+Shift+U then 221e on Linux. Phone keyboards have no ∞ key — copy it from above.

Is there an infinity heart symbol?

Not as one character. You combine ∞ with a heart from the heart symbols page — ∞♥ and ♥∞♥ are the usual forms.

What are the infinity symbols Ꝏ and ꝏ?

Latin letters, not infinity signs — U+A74E and U+A74F, from Middle Welsh orthography. They resemble ∞ closely enough to be borrowed for usernames, and unlike ∞ they behave as letters when text is sorted or searched.
