Double-bogey

In golf, par is the predetermined 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 mostly determines par values for each hole. 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), but tournament players will often encounter par-four holes 500 yards (460 m) or more, as it is common 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, but the latter are not recognised by the United States Golf Association.

Typical championship golf courses have par values of 72, comprising four par-threes, ten par-fours, and four par-fives. Championship course par can be as high as 73 to as low as 69. Most 18-hole courses not designed for championships have a par close to 72, but some will be lower. Courses with par above 73 are rare. Courses built on relatively small parcels of land will often be designed as "Par-3 Courses" in which every hole (or almost every hole) is a par-three (for a total par of 54 or slightly higher over 18 holes).

A golfer's score is compared with the par score. If a course has a par of 72 and a golfer takes 75 strokes to complete the course, the reported score is +3, or "three-over-par" and takes three shots more than par to complete the course. If a golfer takes 70 strokes, the reported score is −2, or "two-under-par."

Tournament scores are reported by totalling scores relative to par in each round (there are usually four rounds in professional tournaments). If each of the four rounds has a par of 72, the tournament par would be 288. For example, a golfer could record a 70 in the first round, a 72 in the second round, a 73 in the third round, and a 69 in the fourth round. That would give a tournament score of 284, or "four-under-par."
