How much higher are the rails on a Russian pool table compare to a regular pool table?

The rails on a Russian pool table are typically about 4.5 to 5 inches high, compared to around 3.5 to 4 inches on a standard American pool table. This increased height is designed to accommodate the unique playing style and larger balls used in Russian billiards, which can affect gameplay and strategy. The difference in rail height contributes to the distinction between the two games.
