What Is the Size of a Roulette Wheel?

A roulette wheel is a circular device that is used to spin a ball around a stationary center point. The ball eventually falls into one of 37 (single zero French/European style roulette) or 38 (double zero American style roulette) colored and numbered pockets on the wheel.

The object of the game is to predict which numbered pocket the ball will fall into.

PRO TIP:The size of a roulette wheel depends on the type of game. American roulette wheels are typically larger than those used in European or French roulette. An American wheel has 38 slots, while a European wheel has 37 slots. The larger size of the American wheel is primarily due to the addition of a double zero slot.

Roulette wheels come in many different sizes. The most common size is 27 inches in diameter with a 1.5 inch ball.

However, there are also wheels that are 36 inches in diameter and wheels that are as small as 12 inches in diameter. The size of the wheel does not affect the odds of the game, but it does affect the speed at which the ball travels around the wheel and how long it takes for the ball to eventually fall into a pocket.

The size of a roulette wheel can have an impact on the gameplay if the player is using a betting system that relies on tracking the winning numbers. Larger wheels tend to produce more predictable results, while smaller wheels can be more chaotic.
