The BCA will sanction Tournament Play on Home and Coin-operated tables produced in sizes other than those recognized above, if the playing area width is one half the length, measured cushion to opposite cushion.

Table Bed height: The table bed playing surface, when measured from the bottom of the table leg, will be 29 1/4 minimum to 30 1/4 maximum.

Pocket Openings and Measurements:
Pocket billiard tables: pocket openings are measured at two points - the first being measured between opposing cushion noses where the direction changes into the pocket (tip to tip). This is called the mouth. The second point of measurement is at the narrowest point at the back of the facing. This is called the throat.

Corner Pocket:
Mouth...................................................4 7/8" minimum to 5 1/8" maximum
Throat...................................................4" minimum to 4 1/4" maximum

Side Pocket:
Mouth..................................................5 3/8" minimum to 5 5/8" maximum
Throat..................................................4 3/8" minimum to 4 7/8" maximum

Vertical Pocket Angle 12 +,or - 1 degree

Shelf: The shelf is measured from the center of the imaginary line that goes from one side of the mouth to the other where the nose of the cushion changes direction to the center of the vertical cut of the slate pocket radius.

Corner Pocket........................................1 5/8" minimum to 1 7/8" maximum

Side Pocket............................................0" minimum to 3/8" maximum

Drop Point Slate Radius: The pocket radius measured from the vertical cut of the slate to the playing surface.

Drop Point Slate Radius...................1/8" r. Minimum to 1/4" r. Maximum

Playing Bed: The playing surface must be capable, either by its own strength or a combination of its strength and that of the table baseframe, of maintaining an overall flatness within a tolerance of .020" lengthwise and .010" across the width. Further, this surface should have an additional deflection not to exceed .030" when loaded with a concentrated static force of 200 pounds at its center. If more than one slab is employed, the slab joints must be in the same plane within .005" after leveling and shimming. The bed must be covered with a fabric, the major portion of which is made of wool, with proper tension to avoid unwanted ball roll-off. Commercial tables must have a 1" - 3 piece set of slate with a wooden frame minimum 3/4" attached to slate. All playing surfaces must be secured to base frame with screws or bolts.

Cushion: Rubber cushions should be triangular in shape and molded with the conventional K-66 profile with a base of 1 3/16" and a nose height of 1", with control fabric molded to the top and base area of the cushion. On carom billiard tables, the triangular k-55 profile cushion is to be maintained, with the control fabric on the underside of the cushion to effect a slower rebound action. On snooker tables, the triangular k66 profile or L-shaped snooker cushion is to be used. The balance of the rail section to which the rubber cushion is glued should be of hardwood construction and attached to the slate bed with a minimum of three (3) heavy duty, threaded rail bolts per rail.
