The Geometric Shapes block (U+25A0–U+25FF) contains the squares, circles, triangles, diamonds, and other regular shapes that appear in diagrams, bullet lists, status indicators, and chess and game notation. The shapes come in matched pairs — solid (filled) and outline (hollow) — in multiple sizes.
The black square (■) and white square (□) are the largest of the squares. The black small square (▪) and white small square (▫) are about half the size and read more like bullets than blocks. The medium black square (◼) is the emoji-style filled block. For any kind of comparison or stacked diagram, pick one weight (large or small) and stick with it.
The black circle (●) and white circle (○) are round, large, and pure — ideal for status dots and bullet lists. The bullseye (◎) and fisheye (◉) combine an outer ring with an inner dot at different sizes. The dotted circle (◌) is the placeholder used in font tables and combining-character documentation; it should not be used as a content circle.
The heavy large circle (⭕) is an emoji-presentation circle that renders in red on most platforms. It is the “O” in correct/incorrect quizzes in some Asian conventions.
The four cardinal triangles — up (▲), down (▼), left (◀), right (▶) — are the most-used shapes in this block. They are the standard for play/pause/forward/back UI controls, expand/collapse arrows in trees, and direction markers on charts. The white (outline) variants exist for the same purposes when a hollow shape is needed.
The black diamond (◆), white diamond (◇), and lozenge (◊) cover most diamond needs. The white-diamond-containing-black-small-diamond (◈) is a compound shape that appears in some game and notation systems. The lozenge is technically narrower than a diamond — it is the rhombus shape used on warning signs.
For flowcharts, the visual conventions are: rectangle for processes, diamond for decisions, parallelogram for input/output, oval for start/end. For status, choose the shape and color that contrast cleanly with the row's background. For bullets, the small filled circle or square at body weight reads cleaner than a large filled shape, which can dominate the line.
If the shape carries meaning — for example, a red square next to an item to mean “danger” — pair it with a text label. Color and shape alone do not communicate to assistive technology unless ARIA labels are added. The Unicode character names (“BLACK SQUARE,” “BLACK CIRCLE”) are read aloud and don't carry your intended meaning.
Geometric shapes pair well with checkmarks and crosses for status, and with arrows for direction in diagrams.
