A perimeter-maximum-diameter method is proposed for measuring the fractal dimension of a fractured surface. The measured values of the fractal dimension by this method seem independent of the length of the yardstick. However, the fractal dimensions D(m) measured by the perimeter-area method decrease as the yardstick length increases. When the length of the yardstick is small enough, the value of D(m) measured by the latter method approaches the value measured by the present method.
