2. Size & Marking

Printer friendly version

The court markings define the playing area of the surface and provide consistency
with the Rules of Tennis and between courts.

2.1 Apparatus

Test apparatus consists of:

  1. Distance-measuring device, calibrated to ± 0.05%, such as a laser distance
    meter or a steel tape.

2.2 Calibration of apparatus

Check the distance-measuring accuracy of the apparatus against a known standard prior to testing.

2.3 Test procedure

  1. Using the calibrated device, measure each of the distances listed in table  (refer also to figure ). Follow the same procedure on both sides of the net to complete the court.
  2. Repeat the measurements in reverse order. Check any measurement for which
    the discrepancy between the two values exceeds half of the applicable
    tolerance.

2.4 Calculation of results

Calculate the mean of the two values measured for each distance. The criterion
values are listed in table. The tolerance for each test value (measured distance)
corresponds to 0.1% of the distance measured, with a minimum tolerance of 5 mm.

2.5 Recommendations

Notes:
a. N and n are measured from the centre of the net posts/singles sticks.
b. In cases where the position of X cannot be located precisely, for instance due to
anchoring of the centre strap, use a reference point midway across the centre
serviceline.
c. All other measurements should be made to the outside edge of lines.
d. Movement of grass during the application of court markings shall be taken into
account when assessing the results.
