Mathematical Bold Capital Sigma Symbol
𝚺 is the Mathematical Bold Capital Sigma character used to represent a bold Σ in math and design.
U+1D6BA
𝚺 (MATHEMATICAL BOLD CAPITAL SIGMA) is a bold, capital Greek sigma. It’s mainly used in math notation and typography where a bold Σ is needed. You can copy it directly or use its Unicode code point in software.
Mathematical Bold Capital Sigma Symbol Meaning
𝚺 is the Unicode character “MATHEMATICAL BOLD CAPITAL SIGMA” (U+1D6BA). The most common meaning is typographic: it provides a bold version of the Greek capital sigma Σ. In mathematical writing, bold variants are often used to distinguish different objects, vectors, operators, or sets from regular text or standard symbols. In practice, designers and technical writers also use it to match the weight/style of other bold math characters. If you’re not working with bold math styling, the regular sigma (Σ) may be the better choice; 𝚺 specifically signals the bold form.
Common uses
- •Mathematical equations that require a bold capital sigma character
- •Typography consistency in math-heavy documents (matching bold math alphabets)
- •Designing posters, slides, or diagrams that use bold Greek notation
- •Programming UI/labels where a bold sigma glyph is preferred
- •Creating math-related icons or branding elements using Unicode math symbols
