Black Square Symbol
■ is the black square symbol (U+25A0), used as a solid geometric marker in text and UI.
U+25A0
The ■ symbol is a solid black square from the Unicode Geometric Shapes block. It’s commonly used when you need a simple, high-contrast square for lists, labels, or visual emphasis.
Black Square Symbol Meaning
The black square ■ primarily represents a solid geometric shape. In everyday writing, it often functions as a visual bullet, a marker for checklists, or a placeholder where a filled box is useful. Designers also use it as a minimal “tile” or accent in UI mockups, posters, or typographic layouts because it stays clearly visible at small sizes. In developer contexts, ■ is convenient for test markers, status indicators, or legend symbols in plain text. Its meaning is usually contextual rather than symbolic; if you want a “filled checkbox” effect, ■ is a practical choice.
