Square Symbol (□)

Square Symbol uses □, U+25A1 WHITE SQUARE. It is an outlined geometric character suitable for plain-text legends, printable option lists, diagram labels, and decorative patterns. A text square is not automatically a checkbox. In an interactive form, a semantic checkbox control must expose its checked state, label, and keyboard behavior. The Unicode glyph may appear beside the label in a printable document, but it cannot supply the form-control semantics. Other square characters have separate code points: BLACK SQUARE ■, small squares, and enclosed forms can differ in fill, size, and intended use. The page is unrelated to the square-root operator √ and to superscript two ² even though those topics share the word “square.” This URL is limited to the outlined shape character. Geometry diagrams that need precise dimensions or scalable outlines may require vector graphics instead of a font glyph. Unicode and accessibility references support the encoded identity and labeled use. The page avoids inventing a universal meaning for □; a legend, option label, or surrounding text must state what the square represents. For Square Symbol, those samples represent lists and legends, decorative text, diagram labels, and unicode references; each one supplies the surrounding context that the symbol alone cannot provide. Select the square variant that matches fill and size requirements. Provide a label when □ conveys status or choice.
