How to Use and Format the Infinity Symbol
The infinity sign ∞ (U+221E) is used in mathematical notation for unbounded behavior, limits, and intervals. It is not an ordinary finite number, so its meaning must come from the mathematical expression in which it appears. For intervals on the real line, an infinite endpoint is written with a parenthesis rather than a square bracket.
Use the proper minus sign with negative infinity when mathematical typography is available, as in −∞. In interfaces or diagrams where ∞ is used as a status or control, add a text label or accessible name instead of relying on the symbol alone.
Use forms such as x → ∞ when describing an unbounded limit.
Write intervals with an infinite endpoint as (0, ∞), [0, ∞), or (−∞, ∞).
Use a parenthesis at infinity because ∞ is not a real endpoint included in the interval.
Use the Unicode character ∞ rather than a rotated digit 8 or a font-specific image.
Define any nonmathematical use of ∞ so readers understand the intended meaning.
Add accessible text when ∞ appears in a button, setting, or status indicator.
Infinity Symbol Examples
x → ∞n → ∞(0, ∞)[0, ∞)(−∞, 0)(−∞, 0](−∞, ∞)lim x→∞ 1/x = 0lim x→∞ e^(−x) = 0∫₀^∞ e^(−x) dx = 1
Common Infinity Symbol Mistakes
- Do not treat ∞ as an ordinary finite real number.
- Do not replace ∞ with the digit 8 rotated or typed sideways.
- Do not confuse ∞ (U+221E) with ♾ (U+267E PERMANENT PAPER SIGN).
- Do not write [0, ∞] for an interval in the ordinary real line; infinity is not a real endpoint.
- Do not use ∞ as a generic replacement for undefined.
- Do not perform ordinary arithmetic with ∞ unless the mathematical system and conventions are stated.
- Do not use a font-specific image when the Unicode character ∞ is available.
- Do not use ∞ alone as an interactive label without an accessible name.
More About the Infinity Symbol
The infinity symbol ∞ is a Unicode text character, not an image. The infinity symbol represents something without a finite bound or end. In mathematics it is used for unbounded quantities and limiting behavior. Because it remains selectable text, it can be copied into documents, messages, spreadsheets, source code, usernames, captions, and other fields that support Unicode. Its appearance can change with the active font or operating system, while the stored character remains U+221E (INFINITY).
Supporting searches such as “copy paste infinity symbol”, “infinity symbol keyboard”, and “how to type an infinity symbol” usually describe the same core task from different angles: identifying the correct character, copying it, or learning how to enter it with a keyboard. This page keeps those intents together so you do not need separate pages for small wording differences. Use the copy control for the fastest method, then check the platform rows when you need a repeatable shortcut on a specific device or app.
Queries such as “infinity character symbol” and “infinity symbol copy” are covered by the keyboard, application, and character-code sections. The Windows and Mac instructions explain practical input methods, while the Microsoft Word and Google Docs rows cover document editing. Unicode, HTML, hexadecimal, and CSS values are listed separately so developers can insert the exact character without confusing it with a similar-looking mark.
Choose ∞ when its documented meaning matches the surrounding text, and compare the related-symbol links below when another character may be more precise. Spacing and visual style can vary by context, so follow the style guide of the document or platform. For example: x → ∞
