Ball Sizes And Standards: 57.2 mm, Snooker And 60.3 mm Russian

American pool: 57.2 mm, or 2-1/4 inches

This is the size behind most of the ball family here, published both in millimetres and in inches on the listings that give both. Eight-ball and nine-ball tables, the pockets cut for them and the rack templates that come with them all assume it. A cue ball ordered for these tables has to be the same 57.2 mm unless the table is a coin-operated one designed around an oversized cue ball.

British snooker and English pool sit smaller

Snooker balls are smaller than American pool balls, and the British snooker sets in this range are published with their own sizing rather than being described as standard. If a room plays English pool or snooker, the American 57.2 mm set is not a substitute at any price.

Russian pyramid runs much larger: 60.3 mm and 61 mm

Russian pyramid is played with larger balls on a larger table with tighter pockets, which is why the 60.3 mm sixteen-ball sets and the 61 mm cue balls in this range exist as separate products. Exporting to those markets means ordering that size specifically, and the listings say so.

Resin type matters more than the colour of the box

Phenolic resin balls are the harder, more impact-resistant option and hold their surface longer under heavy commercial play. Where a listing in this range names phenolic resin, the product page names it too. Where it does not, the page does not claim it, because that distinction is exactly the one suppliers blur.

What the grade codes mean here

8A, 12A and 3A appear on the ball listings as the source's own tiering. They are reproduced as published and used for reordering, not as certified roundness or balance tolerances. No tolerance figure is published by the source, so none is stated here.

Buy the cue ball separately, and buy a spare

The cue ball is the piece a room loses and scuffs first, which is why this range publishes individual cue balls — plain white, red-dot and six-dot training balls — as their own products rather than only inside sets. One spare per table keeps a table in service on the night it goes missing.
