About Infinity Symbol

The infinity symbol ∞ (U+221E) was introduced to mathematics by John Wallis in 1655 in his work De sectionibus conicis. Wallis likely derived the shape from the Roman numeral M (meaning 'many'), or possibly from the Ouroboros — the ancient symbol of a snake consuming its own tail. The lemniscate form, as the shape is technically called, now appears across mathematics, physics, metaphysics, and popular culture.

In Unicode, ∞ belongs to the Mathematical Operators block (U+2200–U+22FF), which was designed to encode the complete set of symbols used in formal mathematics. Despite visual similarity, ∞ is a distinct character from ∞-like shapes such as ∾ (U+223E Inverted Lazy S, used in geometric contexts) and ♾ (U+267E Permanent Paper Sign, an infinity mark used in library cataloging for acid-free archival paper).

Culturally, the infinity symbol has moved far beyond mathematics. It's one of the most popular tattoo designs worldwide, used to represent eternal love, endless possibilities, and limitlessness. On social media, ∞ appears in couple bios, motivational content, and brand identities. The compact, symmetrical lemniscate shape makes it particularly effective as a logo element and decorative character in any text field.

Frequently Asked Questions

How do I type the infinity symbol on keyboard?

On Windows, hold Alt and type 236 on the numpad for ∞. On Mac, hold Option and press 5. On mobile, most keyboards don't include it — the fastest way is to copy it from this page. In HTML use ∞ or ∞. In LaTeX use \infty.

What does the infinity symbol mean in math?

In calculus and analysis, ∞ represents an unbounded limit — not a number, but the concept that a value grows without bound. In set theory, there are multiple infinities of different 'sizes' (Georg Cantor's transfinite numbers ℵ₀, ℵ₁, etc.). In everyday algebra, ∞ appears in interval notation: (-∞, ∞) means all real numbers.

What is the difference between ∞ and ♾?

∞ (U+221E) is the mathematical infinity operator from the Mathematical Operators block. ♾ (U+267E) is the Permanent Paper Sign used in library and archival contexts to indicate acid-free paper — added to Unicode specifically for library cataloging standards. They look similar but serve completely different purposes and belong to different Unicode blocks.

Is the infinity symbol good for a tattoo or jewelry design?

The lemniscate is popular for tattoos because it's symmetrical, compact, and universally meaningful. Common variations: double infinity (∞ interlocked with another ∞), infinity heart (looped with a heart shape), and infinity with words inside the loops. For digital design, the Unicode ∞ character is clean at all sizes, though custom vector versions are better for large-format print.
