Chalkboards are able to be manufactured various styles, sizes and colors. The hues that are most prevalent in a chalkboard background are black and green, in spite of shades of blue, brown, and gray being also available. They are customizable at the time of their manufacturing for incorporating unique graphic elements. A case in point is a music department of any college/ university, which could request that its classroom chalkboards have musical staffs embossed on its surface. The dimension of this board could be as great as 120″ x 48″ when designed for use in classrooms. Its size varies based on its use.
