A clubhead measuring gauge comprises a fixed base capable of rotating and adjusting its position along a circumference and fixing a protractor; an adjustable measuring base for mounting the protractor and allowing the protractor to shift its position in an increasing or decreasing angle; and an assistant measuring base having a standard side. All of the foregoing components are coupled to a base having a flat horizontal surface. By means of the protractor of the adjustable measuring base, the face angle of golfclubs can be adjusted to match the measuring angle of the measurement, and thus reducing the error and improving precision. Further, the fixed base is rotated to the left or right to attach the sole of the golfclub with the horizontal surface of the base for the measurement of the angles of golfclubs.
