Par (score)
In golf, par is the pre-determined number of strokes that a scratch (or 0 handicap) golfer should require to complete a hole, a round (the sum of the pars of the played holes), or a tournament (the sum of the pars of each round). Pars are the central component of stroke play, the most common kind of play in professional golf tournaments. The term is also used in golf-like sports such as disc golf with the same meaning.
The length of each hole from the tee placement to the pin determines par values for each hole primarily but not exclusively. Almost invariably, holes are assigned par values between three and five strokes. For a casual player from the middle tees, a par-three hole will be 100–250 yards (90–230 m) from the tee to the pin. Par-four holes are 250–470 yards (230–430 m), although tournament players will often encounter par-four holes 500 yards (460 m) or more, as it is not uncommon for short par-five holes for normal play to be turned into par-four holes in championship play. Par-five holes are typically 470–600 yards (430–550 m), but in the modern game holes of over 600 yards are becoming more common in championship play. Other relevant factors in setting the par for the hole include the terrain and obstacles (such as trees, water hazards, hills, or buildings) that may require a golfer to take more (or fewer) shots. Some golf courses feature par-sixes and, very rarely, par-sevens, although the latter are not recognised by the United States Golf Association.
