6.1 The Big Table — geometry reset

When pool players try snooker

If you've only played pool, your first frames of snooker will feel weirdly difficult. Same physics, but everything's harder.

The reason isn't your skill — it's geometry. Snooker tables are bigger, balls are smaller, pockets are tighter. The error margin shrinks dramatically.

This lesson covers the geometric differences. Lessons 6.2 and 6.3 cover the rules and the safety-heavy game style.

Note about this app's simulator: the practice drills below run on a 9' pool table (not a 12' snooker table). Concepts apply, but we'll flag where snooker behavior would differ.

Table dimensions: 12 ft vs 9 ft

Standard snooker table playing surface: 11 ft 8.5 in × 5 ft 10 in (~3.57 m × 1.78 m). Standard 9-ft pool table: ~9 ft × 4.5 ft (~2.74 m × 1.37 m).

Snooker has roughly 70% more area. Long-distance shots become significantly harder — small aim errors translate to bigger pocket misses.

Cloth is also different: snooker uses worsted wool (faster, smoother) while pool uses napped wool. Speed decay rates differ — but the fundamental physics (90° tangent, 30° rule, throw, swerve, squirt) are identical.

• 12-ft table is ~70% larger than 9-ft pool
• Same physics, different distances
• Worsted snooker cloth is faster than pool nap

Ball size and pocket geometry

Snooker balls are 52.5 mm in diameter. Pool balls are 57.15 mm (2¼ inches). About 8% smaller.

More important: pocket geometry. Pool pockets have nearly straight jaws ~115 mm wide. Snooker pockets have rounded jaws approximately 89 mm wide at the entrance — and the jaws actively reject balls that don't enter cleanly.

Practical consequence: a ball that would fall in a pool pocket will rattle out of a snooker pocket. The same cut angle that drops a ball in pool may miss in snooker.

This is why contact-point aiming (Lesson 1.1, Method 2) is preferred for snooker — it's more precise than ghost-ball, which loses accuracy at distance.

• Snooker balls 52.5 mm vs pool 57.15 mm
• Snooker pockets ~89 mm with rounded rejecting jaws
• Use contact-point aiming, not ghost ball, in snooker

Tip size and how it affects spin

Snooker cues use 9-10 mm tips. Pool cues use 12-13 mm tips.

Smaller tip + smaller ball = same proportional contact area. But: snooker tips are harder, allowing more precise English with less squirt — which is why pros add subtle side spin on most shots without missing.

Bottom line: the spin physics from Chapter 4 still apply, but the magnitudes differ. Snooker's smaller tip allows finer control; the smaller pocket margin punishes any imprecision.

• Snooker tips: 9-10 mm (vs pool 12-13 mm)
• Harder tips give cleaner English with less deflection
• Same physics, different magnitudes
