What Determines the World Golf Rankings?

By Spencer Lanoue

Ever watch the final round of a major and hear the announcers discuss how a win could catapult a player into the top 10 of the Official World Golf Ranking? It sounds straightforward, but behind that number is a complex, fascinating system that rates every professional golfer on the planet. This article breaks down exactly how those rankings are calculated, covering the rolling two-year period, the critical role of Strength of Field, and how a player's average points are determined.

The Core Idea: A Rolling Two-Year System

The first thing to understand about the OWGR is that it's not a snapshot of who is playing well right now, it's a reflection of performance over a sustained period. Specifically, the ranking is a system that looks at a player’s results over the most recent 104 weeks, or two full years. Think of it like a bucket with a slow, constant leak. Every time a player makes a cut and earns points, they're pouring water into their bucket. But over time, the water they added weeks and months ago slowly leaks out.

Here’s how that aging process works:

  • The Recent Hot Streak (First 13 Weeks): For the first 13 weeks after a tournament, the points a player earns are worth 100% of their value. This is why a player who gets on a tear, notching a few top-10 finishes or a win in a short span, can climb the rankings so quickly.
  • The Slow Fade (Weeks 14 to 104): After the 13-week mark, those points begin to devalue. Every week, a small fraction (1/92nd, to be exact) of their original value disappears. This continues for the next 91 weeks. By the time 104 weeks (two years) have passed since the tournament, those points are worth zero and disappear from the player's calculation entirely.

This "rolling" nature means that to maintain or improve a ranking, a player can’t just rest on a big win from 18 months ago. They have to keep performing, constantly adding new, high-value points to replace the old ones that are leaking away or expiring. It’s what makes getting to World No. 1 so difficult, and staying there even harder.

Strength of Field: Why Not All Tournaments Are Created Equal

This is the engine of the entire OWGR. The system's credibility rests on its ability to fairly weigh performances across different tours and tournaments around the world. A win at The Masters is simply not the same as a win on the Korn Ferry Tour, and the Strength of Field (SOF) calculation is how the OWGR accounts for that difference.

The SOF isn't a subjective measure, it's a purely data-driven value that determines the total number of ranking points a tournament has to offer. The stronger the field, the more points are available to be distributed among the players who make the cut.

How is the Strength of Field Rating Determined?

The SOF for any given tournament is calculated by looking at who is signed up to play that week. Essentially, the system adds up the "ranking power" of every player in the event. This is done through two main components:

  1. World Rating: This value is based on the current OWGR of every player in the field. Every player in the top 200 of the OWGR contributes a certain amount to the tournament's total SOF value. Having the World No. 1 in your field is obviously a huge boost, but so is having 40 of the top 100.
  2. Home Tour Rating: This adds a value for top players from the "home tour" where the event is being held, even if they aren't in the OWGR top 200. It acknowledges that a top 10 player on the DP World Tour or Japan Golf Tour is a significant player, and their presence makes the tournament tougher.

These values are tallied up to create a total "Ranking Points" pool for the tournament. The major championships are allocated a fixed 100 points for the winner, and THE PLAYERS Championship is fixed at 80. For all other events, this pool fluctuates based on the field. One year, a regular PGA Tour event might have an SOF that awards 62 points to the winner. The next year, if more top players decide to play, it might be worth 68.

From there, the points are distributed down the leaderboard according to a curve. The winner gets the biggest prize, the runner-up gets a substantial amount, and so on, with points awarded to every player who makes the cut.

How Players Earn and Stack Their Points

A player's final position on the Official World Golf Ranking isn't based on their total points earned but on their Average Points per Event. This is a simple but important distinction. The calculation for this is:

(Total Points Earned in Last 104 Weeks) / (Number of Events Played)

However, there's a small twist to prevent players from skewing the system: the divisor.

The Divisor: Playing Too Much Can Hurt You (Sort Of)

To ensure a level playing field, the OWGR sets rules for the "Number of Events Played," also known as the divisor.

  • The Minimum Divisor (40): A player's total points are divided by the number of events they’ve played in the two-year period, or by 40, whichever is greater. This prevents a player who might get a shock win in a major from rocketing to the top of the rankings with only a few events played. If a player has only competed in 25 events, their total points are still divided by 40, keeping their average in check.
  • The Maximum Divisor (52): A player's divisor is capped at their last 52 events. Once a player goes beyond 52 events in the two-year window, their most recent results start pushing out their older ones. Playing more than 52 events can diminish their average if those extra tournaments result in missed cuts (0 points) or low finishes.

From a coaching perspective, this is pure strategy. You’ll often see pros take specific weeks off not just for rest, but for schedule management. Playing an event and missing the cut adds a tournament to their divisor without adding any points, which will lower their average. It's a delicate balancing act of playing enough to stay sharp while avoiding tournaments that might dilute their hard-earned points average.

Putting It All Together: A Pro's Ranking Journey

Let's follow a hypothetical player, "Alex," to see how this works in practice.

At the start of the year, Alex is ranked 175th in the world. He's a solid player but on the bubble for getting into the biggest events.

  • January - PGA Tour Regular Event: The SOF is decent but not massive. Alex puts together a great week and finishes T5, earning him 11 Ranking Points. A fantastic start. His average nudges up a bit.
  • March - The PLAYERS Championship (High SOF): Alex manages to qualify. This is a huge opportunity because the winner gets 80 points. He plays well and makes the cut, finishing T35. He only gets 2.5 Ranking Points, but just being there and earning *anything* against such a strong field is a positive.
  • April/May - Mixed Results: Alex plays four more events. He makes two cuts for small points gains (1.5 and 2 points) and misses two cuts (0 points). His average stays relatively flat. He's treading water.
  • June - The U.S. Open: Alex gets through final qualifying and is in the field for a major. The winner gets 100 points. The pressure is on. Against all odds, he has the week of his life. He battles hard and finishes in solo 3rd place. He doesn't win, but he earns a massive 40 Ranking Points.

This is the moment Alex's career changes. Those 40 points, combined with his earlier finishes, cause his average to skyrocket. When the new rankings are released on Monday, he jumps from 150th to 48th in the world.

Now, everything is different. As a top-50 player, he is automatically qualified for all the majors and World Golf Championship events for the next year. He no longer has to hope to qualify, he can set his schedule. This gives him more chances to play in high-SOF events, creating a virtuous cycle where he can earn even more points to solidify his ranking. But remember the leaking bucket: those 40 U.S. Open points will begin devaluing in 13 weeks, and his other points will continue to age. To stay in the top 50, Alex's work is just beginning.

Final Thoughts

The Official World Golf Ranking is a dynamic calculation that beautifully reflects a player's performance over two years, all weighted by the quality of the competition. It accounts for consistency through its rolling average system and rewards peak performance through the Strength of Field model, creating a fair if complex hierarchy for the global game.
