1. Purpose
The purpose of these specifications shall be to set standards for equipment used at all WPA World Championships, WPA World Tour events and other WPA sanctioned and/or recognized events. These specifications do not necessarily apply to tables manufactured for commercial home use. At its sole discretion, the World Pool-Billiard Association can sanction tournaments on tables not in compliance with these specifications.
2. Table Bed Height
Shall be between 29 ¼ inches [74.295 cm] and 31 inches [78.74 cm].
3. Design
Shall not have any sharp edges or materials that might cause injuries or damage clothes. Construction should be adequate enough so that the table will remain stable and level under all conditions of play.
4. Slates
The thickness must be at least 1 inch [2.54 cm], and the playing surface must be capable, either by its own strength or a combination of its strength and that of the table base frame, of maintaining an overall flatness within + .020 inches [.508 mm] lengthwise and + .010 inches [.254 mm] across the width. Further this surface should have an additional deflection not to exceed .030 inches [.762 mm] when loaded with a concentrated static force of 200 pounds [90.7 kg] at its center. All slate joints must be in the same plane within .005 inch [.127 mm] after leveling and shimming. Tournament tables must have a set of slates consisting of three pieces of equal size with wooden frame of at least ¾ inch [1.905 cm] thick lumber attached underneath the slate. The slate sections must be secured to the base frame with countersunk screws or bolts.
5. Playing Surface
The playing surface (area) must be rectangular, and symmetrical when the pocket configurations are included:
- 9 foot - 100 (+ 1/8) x 50 (+ 1/8) inches (except cushions)/ [2.54 m (+
- 3.175 mm) x 1.27 m (+ 3.175 mm)]
- 8 foot - 92 (+ 1/8) x 46 (+ 1/8) inches (except cushions)/ [2.3368 m (+
- 3.175 mm) x 1.1684 m (+ 3.175 mm)]
6. Rail and Cushion
The rail width must be between 4 [10.16 cm] and 7 ½ inches [19.05 cm] including the rubber cushions. 18 sights (or 17 and a name plate) shall be attached flush on the rail cap with:
12 ½ inches [31.75 cm] from sight to sight on a 9-foot regulation table
11 ½ inches [29.20 cm] from sight to sight on a 8-foot regulation table.
The center of each sight should be located 3 11/16 (+ ) inches [93.6625 mm (+ 3.175 mm)] from the nose of the cushion. The sights may be round (between 7/16 [11.11 mm] and ½ inch [12.7 mm] in diameter) or diamond-shaped (between 1 x 7/16 [25.4 x 11.11 mm] and 1 ¼ x 5/8 inch [31.75 x 15.875 mm]). Any nameplates and score counters should be flush level with rail top. All rail bolts should be thus located that when properly torqued render a quiet and optimum rebound from any point of the cushion nose of the table. 7. Height of the Cushion
Rubber cushions should be triangular in shape with the width of the cloth-covered cushion being between 1 7/8 [4.76 cm] and 2 inches [5.40 cm] measured from the outer edge of the featherstrip to the nose of the cushion. Rail height (nose-line to table-bed) should be 63 ½% (+1 %) or between 62 ½% and 64 ½ % of the diameter of the ball.
8. Cushion Rubber
Table cushions should influence the speed of the table such that with placement of a ball on the head spot, shooting through the foot spot, using center ball english, with a level cue and firm stroke, the ball must travel a minimum of 4 to 4 ½ lengths of the table without jumping.
