A simple inexpensive gloss measurement device which makes use of the measurement of a maximum angle of view of a clear reflection to obtain a measurement of gloss, consists of an instrument of L-shaped configuration with one or more small images (e.g., hollow squares) on the lower portion of the shorter arm and a graduated scale along edges of the longer arm. The device is placed on a coated surface to be measured, with the images close to the surface of the coating. The highest angle of view at which reflection of the images on the coating can be clearly recognized is noted on the graduated scale as a measure of the gloss of the coating.
