ABSTRACT:
At least one mark is provided on a tennis racket. The distance between the mark and an end or edge of the racket defines a measurement length which is equal to the difference between the 36" height of the net and the length of the racket. The height of the net can be verified by the combined height of the racket and the measurement length. Three marks may be provided on the strings of the racket head to define the measurement length between each side edge of the racket head and the end of the racket head. Also, a mark may be provided on the handle of the racket.
