Stroke index is a key concept in golf that helps golfers track their performance and improve their game. It is a numerical value assigned to each hole on a golf course, indicating its relative difficulty compared to the other holes. The stroke index is determined by evaluating each hole based on specific criteria, such as length, the difficulty of approach shots, and the presence of hazards. This information is used by golfers to make informed decisions about club selection, shot placement, and overall strategy, helping them achieve better scores and a more enjoyable game. It is also used in tournament play to determine the order of play, with the most challenging holes often played first. While it is related to handicap, which levels the playing field for golfers of different skill levels, the stroke index focuses on the difficulty of the holes rather than the players' abilities.

| Definition | Stroke index is a numerical value assigned to each hole on a golf course that indicates the relative difficulty of the hole. |
| Purpose | It is used by golfers to determine the most challenging holes on a course and to make decisions about club selection, shot placement, and overall strategy. |
| Calculation | It is calculated by evaluating each hole based on specific criteria, such as length, difficulty of the approach shot, and presence of hazards, and then assigning a numerical value based on its relative difficulty. |
| Handicap Strokes | The stroke index is used to determine the number of handicap strokes a player receives on each hole based on their handicap. For example, a player with a handicap of 8 will receive a handicap stroke on holes with a stroke index of 1-8. |
| Variations | The stroke index can vary between golf courses as each course has unique challenges and characteristics. It can also change over time as course conditions evolve or improvements are made. |
| Strategic Value | Knowing the stroke index can help golfers make informed strategic decisions. For instance, a golfer may choose to play more conservatively on holes with a high stroke index. |
| Tournament Play | In tournament play, the stroke index is used to determine the order of play, with holes of the highest stroke index sometimes played first. |
| Misconception | It is a misconception that the stroke index is a ranking of holes purely based on difficulty. Instead, it considers the needs of the handicap system, ranking holes in order of where a bogey golfer would need a stroke from a scratch golfer. |

Stroke index allocation
The Rules recommend the following methodology for stroke index allocation within the six-triad structure, in order to work for both matchplay and strokeplay: Apply odd stroke index allocations over the front nine and even stroke index allocations over the back nine. If, however, the back nine is significantly more difficult than the front nine, as determined by the Course Rating, the even stroke index allocations can be switched to the front nine and the odd stroke index allocations to the back nine. This triad method balances out the most difficult holes in the middle triad.
In Stableford, par and bogey competitions using stroke play, where an even distribution of strokes is not so important, if the club uses a different stroke index for these competitions then generally the most difficult hole to play is given the index of 1 and the easiest is indexed as 18. Technicality and hole length are factors contributing to difficulty. Some clubs allocate different indexes for match play and Stableford/par/bogey matches.
In a handicap match, play competition where one player has a handicap of 8 shots higher than their opponent, that player will receive a handicap stroke on the holes with a stroke index of 1 to 8.

How it impacts handicaps
Stroke index is an important concept in golf that helps golfers track their performance and improve their game. Each hole on a golf course is assigned a stroke index, a numerical value that indicates the relative difficulty of the hole. This value is based on factors such as the length of the hole, the complexity of the approach shot, the location of hazards, and the difficulty of the green.
The stroke index directly impacts handicaps, which are measures of a golfer's ability used to level the playing field for golfers of varying skill levels. The relationship between the two concepts is that the handicap determines the number of strokes a golfer is given on each hole, depending on their ability level. For instance, a golfer with a handicap of 20 will receive one stroke on holes with a stroke index of 1-18 and two strokes on holes with a higher stroke index of 19-36. This allows golfers of different skill levels to compete on equal terms.
In a handicap match play competition, if a player has a handicap that is eight strokes higher than their opponent, they will receive a handicap stroke on the holes with a stroke index of 1 to 8. The stroke index is typically printed on a golf club's scorecard, visible to golfers. This information helps golfers make informed decisions about club selection, shot placement, and overall strategy. For example, if a golfer is aware that a particular hole has a high stroke index, they may opt for a more conservative approach to aim for a safer area of the fairway or green.
Additionally, the stroke index is used in tournament play to determine the order in which holes are played. While it is somewhat random, the holes with the highest stroke index, indicating the most difficult holes, are sometimes played first. This allows players to adjust their strategies as they progress through the round. The stroke index can vary between golf courses as each course has unique challenges and characteristics, and it can also change over time as course conditions evolve or improvements are made.

How it affects club selection
The stroke index is a numbering system used in golf to indicate the relative difficulty of each hole on a course. Each hole is assigned a unique stroke index number from 1 to 18, with 1 representing the most challenging hole and 18 the easiest. This system is separate from the hole number and is used to determine handicap strokes and stableford points.
The stroke index is an important tool for golfers as it helps them make informed decisions about club selection, shot placement, and overall strategy. By understanding the stroke index of each hole, golfers can adjust their approach and improve their performance. For example, if a golfer knows that a particular hole has a high stroke index, they may choose to play more conservatively and aim for a safer part of the fairway or green. This allows them to avoid taking unnecessary risks and focus on careful planning and execution.
On the other hand, if a golfer encounters a low stroke index hole, they may adopt a more aggressive strategy to maximise scoring opportunities. This involves taking calculated risks and capitalising on their strengths to gain an advantage. By utilising the stroke index information, golfers can navigate the course with a well-planned approach, improving their chances of success.
Additionally, the stroke index can help golfers identify their strengths and weaknesses. By tracking their scores and performance on holes with different stroke indexes, golfers can pinpoint areas for improvement. This self-evaluation enables them to focus their practice efforts and refine their skills, ultimately enhancing their overall game.
It is important to note that the stroke index is not solely based on hole difficulty. Other factors, such as hole length, the number of bunkers and water hazards, and scoring variability between players, also contribute to the stroke index allocation. Therefore, golfers should study course maps, yardage books, and the layout of the course to fully understand the challenges presented by each hole and make optimal club selections.

How it determines the order of play
The stroke index is a system used to rank the holes on a golf course based on their difficulty. Each hole is assigned a number from 1 to 18, with 1 being the most difficult and 18 the easiest. This ranking considers various factors, including hazards, layout, elevation changes, and hole length. The stroke index is used to determine the order of play in tournament play, with the holes with the highest stroke index sometimes played first and those with the lowest played later in the round. This allows players to adjust their strategy as they progress through the round.
The stroke index allocation is covered in Appendix E of the Rules of Golf, which suggests that it is based on difficulty relative to par. The course should be split into six groups of three holes, with each hole ranked based on playing difficulty relative to par. The Rules recommend applying odd stroke index allocations to the front nine holes and even stroke index allocations to the back nine. However, if the back nine are significantly more difficult than the front nine, the even stroke index allocation may be used for those holes.
In match play, the stroke index is used to determine on which holes handicap strokes should be applied. If a golfer has a handicap index of 10 strokes for a course, they receive one extra stroke on the 10 most difficult holes, as defined by the stroke index. This helps to create a level playing field for golfers of different abilities. The stroke index order is not as important as ensuring that strokes are spread out and that consecutive low strokes and low strokes at the beginning or end of each nine are avoided.
The stroke index can vary between golf courses as each course is unique and has its own set of challenges. It can also change over time as course conditions change or improvements are made. Golfers can use the stroke index to identify their strengths and weaknesses and adjust their strategy accordingly. For example, if a golfer knows a hole has a high stroke index, they may choose to play more conservatively.

How it varies between courses
The stroke index is a numerical ranking system that indicates the relative difficulty of each hole on a golf course. Each hole is assigned a unique stroke index number, which helps players understand the difficulty level of each hole. The stroke index is used to calculate the net score for each hole, which is then used to determine the number of points earned.
The stroke index varies between courses because no two golf courses are identical. Each course is designed with its own unique challenges based on terrain, climate, and layout. The playing difficulty relative to par is assessed to determine the stroke index for each hole. Consequently, stroke index rankings are adapted to fit the character of the course. For example, a par-5 hole on one course may be ranked as Stroke Index 2, while a similarly challenging par-4 may carry the same ranking on another course.
The process of calculating the stroke index is usually performed by the golf club and local governing bodies, who evaluate variables such as the length of the hole, the difficulty of the approach shot, the location of hazards, and the difficulty of the green. Longer holes, often referred to as having greater hole length, are inherently more challenging for most players and often receive lower Stroke Index numbers. The number and placement of bunkers, water hazards, and rough areas are considered crucial challenges when assigning an index. Some holes see higher scoring variability between players, contributing to a more challenging rank.
To ensure fairness in match play, consecutive low stroke index holes are avoided, and low stroke index holes are typically not placed at the beginning or end of a nine. Additionally, it is recommended that Stroke Index 7, 8, 9, and 10 should not be allocated to adjacent holes to avoid a player receiving 10 strokes by having a shot on at least three consecutive holes.
