What Are Pool Ball Sizes and Does It Really Matter?

Pool balls, also known as billiard balls, come in various sizes depending on your game type.

Each game has its own set of ball size and weight regulations to ensure fair and consistent gameplay.

Here’s a breakdown of the most common pool ball sizes you’ll encounter:

1. Pool or Pocket Billiard Balls

These are the standard balls used in popular pool games like eight-ball, nine-ball, and straight pool.

Pool balls are numbered and colored, with each number representing a specific ball. The regulation size and weight of pool balls are as follows:

  • Diameter: 2¼ inches (57 mm), with a tolerance of ± 0.005 inches (0.127 mm).
  • Weight: Typically ranging from 5½ to 6.0 ounces (160–170 grams).

It’s essential to adhere to these regulations to ensure consistency and fairness during gameplay.

Coin-operated pool tables may use a slightly different-sized cue ball for convenience, but it’s crucial to maintain uniformity for optimal performance.

2. Carom (Billiard) Balls

Carom billiards, also known as carambole, is played on pocketless tables with three balls: two cue balls and one object ball. Carom balls are not numbered and come in a standard size and weight:

  • Diameter: Between approximately 2⅜ and 2⅞ inches (61–61.5 mm).
  • Weight: Ranging between 7.2 and 7.8 ounces (205 and 220 grams), with a typical weight of 7.5 ounces (210 grams).

These balls are typically white or red, with cue and object ball variations.

3. Snooker Balls

Snooker is a popular cue sport played on a large rectangular table with six pockets. Snooker balls are smaller than pool balls and come in a standard size and weight:

  • Diameter: Standardized at 2.07 inches (52.5 mm), with a tolerance of ± 0.002 inches (0.05 mm).
  • Weight: Must be the same within a tolerance of 0.11 ounces (3 grams).

While regulation snooker balls adhere to these standards, smaller sets are available on smaller tables or in amateur leagues.

4. Bumper Pool Balls

A bumper pool is a unique variation of pocket billiards played on a special table with bumpers and pockets. Bumper pool balls come in a smaller size compared to standard pool balls:

  • Diameter: Usually 2⅛ inches (54 mm).

These balls are typically white and red, with two unique balls featuring red and white spots.
