The proportional scale is a tool that calculates the new dimension of a piece
of scaled artwork and the percentage of reduction or enlargement. It is
composed of two disks joined at the center with a fastener that allows the
disks to rotate. The disks are approximately 6 inches in diameter and made
of a white laminate lettered in black.
