What Does 6 Under Mean in Golf?

Seeing 6 Under next to a player's name on a professional golf leaderboard instantly tells you they're having an excellent round or tournament, but what does it actually mean? Put simply, it means their score is six strokes better than the expected standard for the course, known as par. This article will fully explain the concept of par, what it takes to shoot a score of 6 under, and provide context for just how impressive an accomplishment it really is.

Understanding 'Par': The Foundation of Golf Scoring

Before we can appreciate what 6 under par signifies, we have to have a solid handle on the concept of 'par'. In golf, every hole is assigned a "par" number, which is the predetermined number of strokes a highly skilled golfer is expected to take to complete that hole. The par for a course is simply the sum of the pars for all of its holes, which is most often 72 for a standard 18-hole course.

How Par is Determined for a Hole

The par for a specific hole is based almost entirely on its length - the distance from the teeing ground to the pin. To calculate this, the course architect assumes it will take a skilled player two putts on the green, with the remaining shots used to get the ball from the tee to the green.

• Par-3: These are the shortest holes. You're expected to hit the green with your first shot (the tee shot) and then take two putts. Total: 3 strokes.
• Par-4: These are mid-length holes. The expectation is a tee shot onto the fairway, a second shot (an approach shot) onto the green, and two putts. Total: 4 strokes.
• Par-5: These are the longest holes on the course. They are designed to be reached in three shots by a top golfer (a tee shot, a second layup shot, and a third shot onto the green), followed by two putts. Total: 5 strokes.

How Par is Determined for a Course

A standard 18-hole golf course usually consists of a mix of these holes. A typical Par-72 course layout could be:

• Four Par-3 holes (4 x 3 = 12 strokes)
• Ten Par-4 holes (10 x 4 = 40 strokes)
• Four Par-5 holes (4 x 5 = 20 strokes)

Adding those up (12 + 40 + 20) gives you a total par of 72. If a golfer shoots a score of exactly 72, they are said to have shot "even par" or "E." Any score lower than 72 is "under par," and any score higher is "over par."

The Direct Answer: So, What is 6 Under?

A score of "6 under par" means a golfer's total score is six strokes fewer than the par for the number of holes they've played. This is represented as -6 on a leaderboard.

This can mean two different things depending on the context: a single round score or a cumulative tournament score.

• For a Single Round: If a golfer is 6 under par for one 18-hole round on a par-72 course, they finished the round in 66 strokes (72 - 6 = 66). This is an exceptional score.
• For a Tournament: Professional tournaments are typically played over four rounds (72 holes). The total par for the tournament would be 288 (72 x 4). A player finishing at 6 under par for the tournament would have a total score of 282 strokes (288 - 6 = 282). This demonstrates outstanding consistency over several days of competition.

The Terminology of Under-Par Scores

While we can refer to a entire round as "6 under," golf also has a special, and more colorful, vocabulary for spectacular scores on individual holes.

• Birdie: One stroke under par on a hole (e.g., getting a 3 on a Par-4).
• Eagle: Two strokes under par on a hole (e.g., scoring a 3 on a Par-5, or making your tee shot on a Par-3, known as a Hole-in-One).
• Albatross (or Double Eagle): Three strokes under par on a hole. This is incredibly rare. It usually happens by scoring a 2 on a Par-5 (holing out your second shot) or a Hole-in-One on a Par-4.
• Condor: Four strokes under par on a hole. This is the rarest score in golf - a hole-in-one on a Par-5. It is a shot of almost mythological status and has only been officially recorded a handful of times in history.

How Can a Golfer Actually Achieve a -6 Score?

Shooting 6 under par doesn't happen by accident. It requires a potent combination of intelligent strategy, precise execution, and often a bit of good fortune. Let's look at the different ways a player can get there, because they tell different stories about the golfer's performance.

Recipe for a 6-Under Round (Score of 66)

Putting together a round of 66 is the stuff of dreams for most golfers. It means you were firing on all cylinders. The putter was hot, the iron shots were accurate, and you likely avoided any major mistakes. Here are a few ways it could happen:

• The Birdie Barrage: This is a very common path to a low score for professionals. The scorecard would show 6 birdies and 12 pars. This indicates a player who was relentlessly consistent, avoiding costly bogeys (one over par) and capitalizing on their high-quality approach shots by making the putts.
• The Eagle-Fueled Round: This shows a player who took advantage of the scoring opportunities on the Par-5s. A scorecard could read: 1 eagle, 4 birdies, and 13 pars. The player gets a huge two-stroke boost from the eagle and complements it with a solid number of birdies.
• Flawed but Brilliant: Even a round of 66 can have mistakes. A player might score an eagle, 6 birdies, 2 bogeys, and 9 pars. While not "clean" (more on that below), this shows incredible resilience. The player made a couple of errors but immediately bounced back with outstanding play to erase them and keep climbing down the leaderboard.
• The "Clean Scorecard": This is a mark of pride for many golfers. A scorecard is considered "clean" if it contains no scores of bogey or worse. Shooting 6 under with 6 birdies and 12 pars is considered a "clean 66" and speaks to a state of total control over one's game.

Strategy for a 6-Under Tournament Score

Finishing a four-day tournament at 6 under par is a different kind of achievement. It's less about a single flash of brilliance and more about sustained excellence and mental toughness. Here’s a look at how a player might get to a cumulative score of -6 (282 total) on a par 72 course:

• The Picture of Consistency:
  • Round 1: 70 (-2)
  • Round 2: 71 (-1)
  • Round 3: 71 (-1)
  • Round 4: 70 (-2)
  This is a grinder. This player didn't have a single incredibly low round but was solidly under par every single day. They controlled their misses, stayed out of big trouble, and methodically posted good scores. This is often the mark of a seasoned veteran.
• The One Great Day:
  • Round 1: 67 (-5)
  • Round 2: 73 (+1)
  • Round 3: 72 (E)
  • Round 4: 70 (-2)
  This player came out of the gates on fire, rode that momentum, and then successfully managed their game for the rest of the week to hold onto a great finish. You often see this pattern from players who win their first big event.

Context is Everything: How Good is 6 Under Par, Really?

The impressiveness of a 6 under par score is relative to who is achieving it.

For a Professional Golfer

On the PGA Tour, a single-round score of 66 (-6) is a fantastic round. It will almost always move a player significantly up the leaderboard and often puts them in contention heading into the next day. However, it's a score that top professionals are capable of shooting several times a season.

Over an entire tournament, a final score of -6 is a very respectable finish. On a difficult course like Oakmont during the U.S. Open or Augusta National for The Masters, -6 could be enough to win the entire championship. On a course designed for low scoring during a "birdie-fest" tournament, -6 might only be good for a top-30 finish. For instance, at The 2024 American Express tournament, a score of -6 after four rounds would have landed you in 67th place.

For an Amateur Golfer

For a recreational player, shooting a 6-under-par 66 is the golf round of a lifetime. It is a monumental achievement that very few non-professionals will ever experience. Even for a "scratch" golfer (a player with a 0 handicap), shooting a 66 is an exceptional and rare event. For the average weekend golfer who typically shoots in the 90s, recording a 66 is almost unimaginable. It is the kind of round you frame the scorecard for and talk about for years to come.

Final Thoughts

In summary, "6 under" is a performance benchmark representing a score six strokes better than par. Whether achieved in a single day of spectacular shot-making or over four days of consistent, intelligent play, it signals a golfer is playing at a genuinely elite level.
