What is the minimum number of holes for a PGA recognized golf course?

A PGA recognized golf course must consist of a minimum of nine holes. This standard reflects the traditional layout that allows for a complete game of golf, even if it's played in a partial format. A nine-hole course provides enough variety and challenge for players while being more accessible for those who may have time constraints, enabling them to complete a round within a shorter timeframe. Furthermore, the nine-hole configuration is often considered sufficient for the purpose of hosting golf tournaments and providing an enjoyable golfing experience.

The other options, while they may represent different types of courses, do not meet the PGA’s minimum standard for recognition. For instance, a six-hole course would typically be regarded as too limited in terms of the playing experience, while 12 and 18 holes surpass the minimum requirement, with 18 holes being the standard for full-round play in professional contexts.
