Golf Course Grass Height
The standard height for grass on a golf course varies, but typically it is maintained between 0.125 and 0.5 inches (0.3 to 1.3 centimeters) on the greens, while fairways are kept at around 0.375 to 0.75 inches (1 to 1.9 centimeters), and roughs can range from 1.5 to 3 inches (3.8 to 7.6 centimeters).

The Greens: Precision and Speed
On the greens, the grass is kept at its shortest length to ensure that the ball rolls smoothly and predictably. This requires meticulous maintenance and regular mowing to maintain the desired height. The exact height can vary depending on the type of grass and the climate, with some courses opting for even shorter grass to increase the speed of the green.

Fairways: Playability and Strategy
Fairways are designed to provide a good lie for players' shots, so the grass here is slightly longer than on the greens. This length helps to cushion the ball but still allows for a clean contact when hitting. The height of the fairway grass can also be adjusted to influence play strategies, with some courses keeping it shorter to encourage more aggressive play.

Roughs: Punishment and Challenge
The rough areas surrounding the fairways are intentionally kept longer to penalize errant shots. This longer grass can significantly affect the ease with which a player can hit their ball, making it more challenging to recover. Courses often use different lengths of rough to add strategic elements, with some areas being more penalizing than others. This variation in grass height across the golf course adds to the complexity and enjoyment of the game.
