Copy and paste square symbols — filled, outlined, and patterned squares and rectangles for bullets, checkboxes, design, and diagrams. Square characters work as clean list markers, empty and filled checkbox stand-ins, or blocks in ASCII-style layouts. This collection gathers black and white squares in several sizes, along with shaded and patterned variants and small and rounded forms. Tap any symbol to copy it, then paste it into a document, a bio, a design, or a message. As standard Unicode characters they stay crisp and monochrome across apps and platforms.
