Sidewalk chalk is typically large and thick sticks of chalk that come in multiple colors and are mostly used for drawing on pavement or concrete sidewalks, frequently four square courts or a hopscotch boards. Blackboard chalk, typically used in educational settings, is shorter and thinner than sidewalk chalk.

A sidewalk, pavement, footpath in Australia, India, New Zealand and Ireland, or footway is a path along the side of a road. Usually constructed of concrete, pavers, brick, stone, or asphalt, it is designed for pedestrians. A sidewalk is normally higher than the roadway, and separated from it by a kerb. There may also be a planted strip between the sidewalk and the roadway and between the roadway and the adjacent land.
