A blackboard typically has a rectangular shape, often mounted vertically on a wall for ease of writing and visibility. However, some blackboards can be found in other shapes, such as square or circular, depending on their design and intended use. The surface is generally smooth and matte to allow for easy writing with chalk.

To make a poster board black, you can either purchase pre-blackened poster board from a craft store or paint a white or colored poster board with black acrylic or spray paint. If using paint, apply it evenly with a brush or roller, allowing it to dry completely between coats for a solid finish. Alternatively, you can cover the poster board with black construction paper or contact paper for a smooth, black surface.
