Tables and pockets

[wahcheck]

With my limited knowledge of pool equipment, I have gathered that Brunswick Gold Crown and Diamond tables are two favorite tables to play on........
Are the pocket sizes of 4-1/2 by 9' pool tables standardized? I know many pool tables in pool halls are "customized" to where the pockets are shimmed to make them smaller......what is the largest and smallest pocket sizes on pool tables?

In World class tournaments, are the pocket sizes a standard sized opening?
Are the pocket sizes varied from tournament to tournament?

Obviously, tournaments which use large "bucket" size pockets will have different outcomes than those that have smaller sized pockets.....and I know that different pool halls will have different equipment with different sized pockets....

I was just wondering if there is a standard for professional tournaments.

Thanks for any input or info about this.

You are confusing pool with an organized activity.

Corner Pocket Mouth: between 4.5 [11.43 cm] and 4.625 inches [11.75 cm]
Side Pocket Mouth: between 5 [12.7 cm] and 5.125 inches [13.0175 cm]
*The mouth of the side pocket is traditionally ½ inch [1.27 cm] wider than
the mouth of the corner pocket.

Vertical Pocket Angle (Back Draft): 12 degrees minimum to15 degrees maximum.

Horizontal Pocket Cut Angle: The angle must be the same on both sides of a pocket entrance. The cut angles of the rubber cushion and its wood backing (rail liner) for both sides of the corner pocket entrance must be 142 degrees (+1). The cut angles of the rubber cushion and its wood backing (rail liner) for both sides of the side pocket entrance must be 104 degrees (+1).

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 vertical cut of the slate pocket cut. Shelf includes bevel.

Corner Pocket Shelf: between 1 [2.54 cm] and 2 ¼ inches [5.715 cm]
Side Pocket Shelf: between 0 and .375 inches [.9525 cm]

That's the theory - Reality may differ.
