PROBLEM TO BE SOLVED: To provide a gauge for measuring corner dimensions that readily measures the dimensions of a round-shaped corner. SOLUTION: The gauge for measuring corner dimensions 1 is formed of a transparent or semi-transparent material in plate and includes a first radial dimension measuring unit 2 having two straight lines 21 (21a, 21b) arranged so as to be orthogonal to each other; a plurality of arcs 20 (200 to 259) having different radii differing from each other and using the two straight lines 21 (21a, 21b) as tangents; and a first radius scale 22 that indicates the radial dimensions of the respective arcs 20 (200 to 259) and is displayed.
