Mathematical Fraktur Small S Symbol
𝔰 is the Mathematical Fraktur small letter S (U+1D530) used mainly in math typography.
U+1D530
𝔰, also known as Mathematical Fraktur Small S, is a Unicode character commonly seen in mathematical notation and stylized text. It has a specific code point (U+1D530), which makes it reliable for documents, web pages, and design assets.
Mathematical Fraktur Small S Symbol Meaning
𝔰 is the Unicode character named MATHEMATICAL FRAKTUR SMALL S (U+1D530). It belongs to the “Math” category and is typically used where a fraktur-style lowercase S is desired—most often in mathematical writing to distinguish symbols by script or font style. Because it’s a distinct Unicode code point (rather than a plain italic “s”), it can display consistently when the user’s system has a math-capable font. In plain text and design contexts, people use it to create a formal, “mathematical” look for variables, labels, or headings.
Common uses
- •Using a fraktur-style variable in math expressions or papers
- •Styling a lowercase S in technical diagrams and labeled equations
- •Creating consistent typographic branding for math-oriented projects
- •Embedding the symbol in web content using the correct Unicode character
- •Generating accessible formulas or notation where script matters
