What is the maximum number of holes required in a golf course operated under PGA standards?

In golf, a standard course recognized by professional organizations like the PGA typically consists of 18 holes. This format has become the norm for competitive play and is widely adopted for full-length golf courses. An 18-hole layout allows for a complete game that includes different challenges and experiences across various types of holes, such as par 3s, par 4s, and par 5s.

Courses with fewer than 18 holes, such as those with 9, 10, or even 27 holes, can exist and may be used for casual play or specific purposes. However, for PGA standards, the emphasis is on a full-length test of skill and strategy, which is embodied in the traditional 18-hole configuration. This structure is essential for organizing tournaments and maintaining the integrity of competitive play in the sport.
