Watching a professional golf tournament on a Friday afternoon brings a special kind of drama, all centered around a single, shifting number: the cut line. You see it flashing on the screen, hear the commentators talk about it constantly, and watch players grind over three-foot putts to stay on the number. Seeing that line is one thing, but understanding the forces that push and pull it up and down is another. This guide will walk you through exactly what determines the cut line in golf, from the basic rules to the subtle factors that make every tournament's cut a unique challenge.

First, What Exactly Is the Cut?
The cut is a mechanism used in most professional golf tournaments to reduce the field of players after the first two rounds (typically played on Thursday and Friday). Most stroke-play events on a major tour, like the PGA TOUR, start with a large field - often 144 or 156 players. Managing that many golfers for four full days is a logistical challenge, affecting everything from the pace of play to the television broadcast schedule.
In short, the cut serves two main purposes:
Logistics: It makes the weekend rounds more manageable, allowing for faster play with fewer golfers on the course. Players go out in pairs on Saturday and Sunday instead of the threesomes used on Thursday and Friday.
Drama and Stakes: It creates a high-stakes battle. Players who "make the cut" advance to the final two rounds and, most importantly, get paid for their performance that week. Players who "miss the cut" go home with nothing.
While many casual fans believe the cut is a set score, like even par, that’s a common misconception. The cut line is not a predetermined score, it's determined by a tournament's specific rule regarding the number of players who advance.

The most common cut rule, used by the PGA TOUR, is that the top 65 players and anyone tied with the 65th-place player make the cut. This is the cornerstone of understanding how the line is formed.
Let's walk through an example. Imagine after 36 holes, the leaderboard looks something like this:
...
62nd Place: Player A at +1
63rd Place: Player B at +1
64th Place: Player C at +1
65th Place: Player D at +2
66th Place: Player E at +2
67th Place: Player F at +2
68th Place: Player G at +2
...
75th Place: Player H at +3
Even though there are players ranked lower than 65th, Players E, F, and G are tied with the player in 65th place at a score of +2. Therefore, the cut line would be set at +2, and all players with a score of +2 or better would advance to the weekend. In this case, 68 players would make the cut, not just 65.
Because the cut is based on player count, the actual score can fluctuate dramatically from week to week. A cut might be -5 one week and +5 the next. So, what causes this variation?
The 4 Forces That Constantly Move the Cut Line
Think of the cut line as a floating target driven by four constantly changing variables. As a golf coach, understanding these elements is fundamental to course strategy, and as a fan, it makes watching the Friday action far more compelling.
1. Course Difficulty and Setup
This is probably the biggest factor. A golf course's inherent design and how it's prepared for a tournament have a massive impact on scoring. Some courses are just easier to score on than others.
Difficult Courses (U.S. Open Style): Courses set up for majors, particularly the U.S. Open, are made to be brutally difficult. We're talking narrow fairways, thick and penal rough, lightning-fast greens, and very challenging hole locations. On these courses, par is an excellent score, and you'll regularly see the cut line fall in the range of +4 to +8.
Easier Courses (Birdie-Fests): On the other hand, some tour stops are designed to yield lots of birdies. These courses often have wider fairways, manageable rough, and softer greens. At events like The American Express or the John Deere Classic, players know they need to "go low," and it’s common to see a cut line at -3, -4, or even deeper into red numbers.
2. Weather Conditions
Weather is the great equalizer. Even the easiest course setup can become a monster if the conditions turn sour. Wind is the most significant scoring disruptor, but rain and cold also play major roles.
Wind: A windy day can add two to four strokes to a player's score. It makes club selection a guessing game, affects the flight and roll of the ball, and is mentally exhausting.
Rain: Heavy rain can make the course play longer as the ball doesn't roll out on the fairways. It makes clubs and grips slippery and can make greens unpredictable.
A classic example is The Open Championship in the UK, where brutal coastal wind and rain can send scores soaring and push the cut numbers much higher than they would be in calm conditions.
3. Strength of the Playing Field
The overall talent level of the golfers in a tournament also has a subtle effect. When you gather the world’s best players for a Major or a "Signature Event," the average skill level is incredibly high.
A field where every player is capable of shooting low scores creates more competition around that 65th-place bubble. This intense competition can push the cut line lower (a better score) by a stroke compared to a "regular" tour event where the field might not be as deep with top-tier talent. More good players mean you have to shoot a better score to stay ahead of at least 90 of them.
4. Tournament Rules & Field Size
While Top 65 and ties is the standard, it's not universal. Different tournaments have their own rules which directly dictate how the cut operates.
The Masters: This has the most unique rule. The cut is made for the Top 50 players and ties AND anyone within 10 strokes of the leader. This "10-shot rule" can be a lifeline. If the leader is at -8, anyone at +2 or better is guaranteed to play the weekend, even if they are outside the top 50. It’s designed to keep more players in the mix.
The PGA Championship: This major takes the Top 70 and ties.
The U.S. Open: Unlike the others, they take only the Top 60 and ties, making it the most exclusive cut in major championship golf.
No-Cut Events: Some events, like The Sentry, The Tour Championship, and World Golf Championship (WGC) events, have smaller, elite fields and no cut at all. Every player is guaranteed to play all four rounds and take home a paycheck.
The starting field size of regular events also makes a difference. A 156-player tournament requires you to beat 91 players (plus ties) to make the cut. A 132-player event only requires you to beat 67. This slight mathematical difference can influence where the line ultimately lands.

"Made Cut, Did Not Finish" (MDF) - The Rule That Was
Occasionally, you might hear older golf fans or commentators mention "MDF." This stood for "Made Cut, Did not Finish" and was a secondary cut rule the PGA TOUR used for a while.
It came into play when the "top 65 and ties" rule resulted in more than 78 players making the weekend. If, for instance, 82 players made the cut at +2, the TOUR would implement another cut after Saturday's third round. Only the top 70 and ties after 54 holes would play on Sunday. The players cut on Saturday were given the "MDF" designation, receiving official prize money and FedExCup points, but they were not allowed to finish the tournament.
This rule was unpopular with players and fans alike and was eliminated in 2019. Now, however many players make the initial 36-hole cut get to play the full weekend.
