The Rule of 24: How to shoot low scores like a tour pro without changing anything in your game



I play a lot of golf, mostly at municipal courses, generally with average golfers who suffer from the current epidemic of LOFT (Lack of F***ng Talent). A couple of months ago, watching a pair older guys ride the struggle bus, I thought “someone’s gotta make this better.” When one of my regular playing partners called to tell me had quit, that he was done with the game, that he had other ways to torture himself, I set out to find a solution for him and everyone else who ain’t never gonna play on tour.

Unlocking a solution wasn’t easy. I thought about the question for months and months getting nowhere. And then one day I asked myself a simple question: How far does the average PGA Tour pro hit the ball? The number 300 immediately popped into my head. Next, I asked myself, how long is the average PGA tour course? 7,200 yards popped into my head. Then, I started doing some simple math in my head and stumbled on a simple key: 7,200 divides by 300 into a nice, neat number: 24. The average PGA Tour course is roughly 24 times as long as the average tour player drives the ball.

Could 24 times your driving distance be a basic anchor for how long of a course people should play? Could 24 be some sort of a key to unlocking the game?

Walking on the golf course the other day, I wondered what the rule of 24 would mean for my playing companions. First, there was Steve. He is a mid-40s investment banker who says he hits the ball 210 off the tee but really hits it about 180. He plays a course that is 6,200 yards short. His ratio? 34.4. Yikes. Then there is Patricia, his wife. She hit it about 130 and plays from 5,600—a ratio of 43! Okay folks, Dustin Johnson’s ratio is below 24, Steve’s is 34 and Patricia’s is 43. Who do you think is having more fun playing golf? No wonder the average golfer struggles, I thought, they are playing courses almost 2x the proportional length of a PGA Tour player’s course with 50 percent less power and accuracy. That ain’t nothing but crazy.

Based on that small piece of research, I decided to take the question a step further by asking a couple of more questions: How many greens in regulation does the average PGA Tour player hit vs the average 20 handicap male? The answer is approximately 12 for the PGA Tour player and one for the 20 handicaps. But why? My instincts suggested distance. I called a couple of stats people and asked a question: At what distance does the average 20 handicap man and 20 handicap women hit the green approximately 50% of the time? No one knew. So, I decided to do some really basic data collection to see what I would find. A week later and several 1,000 balls hit on the range by anyone and everyone I could round up later and measured on my launch monitor, the data suggested the distance of the 20 handicap men is approximately 110 yards and for the women, it’s 60 yards.

So how many times would a guy who hits it 180 have 110 yards on an average 6,200 golf course? Basically never. Pretty much same with the ladies hitting it from 5,600. No wonder the average 20 handicapper hits one green per round (if they are lucky)!

Armed with the data, I decided to test it with my favorite golfer—my mom. On a normal drive, my mom hits it about 135 yards. She plays to a 38 handicap. Based on my math, she should be playing a course that is about 2,430 yards. From that distance, she should hit 14 drives approximately 1,890 yards, leaving approximately 30 yards to each green on an 18 hole course.

With this math in mind, I created a 9-hole course and took her to play. The result? She hit 7 greens in regulation, had 2 birdies and 2 bogeys and shot even par. Did she have fun? Did she feel good. How did you feel the last time you shot even par? Exactly…

Since that day with my mom, I have been testing my method with others. Yesterday, I got paired with a lovely older gentleman named Michael. Michael is in his late 60s, is a lifetime golfer with a lovely swing and keenness for the game that was evident from the moment I met him.

Unfortunately, through the first 6 holes, from the senior tees, Michael failed to make anything better than double bogey and was very frustrated; his two longest shots were nowhere close to the green. On 7, I told him about the rule of 24 and asked if he would like to try it out? He agreed. I did the math. I walked him to 203 yards from the green. He hit an average driver and had about 85 yards. He pulled his 7 iron and hit a nice shot that hopped twice and ended about 18 feet from the pin. I gave him a high five and said “good par!”

“Par?” Michael asked, “Really, Brendan, I’m knocking that putt in!” Which he did. His first birdie in two years. Pretty cool.

Okay, folks, you all like to hit the big club far, but I gotta tell you something, I have yet to find someone who doesn’t prefer shooting par.

At this point, some of my math-inclined readers might be upset because they have figured out that based on my math, someone who flies it 240 would play 5,760. Immediately this might raise some eyebrows; that’s why there is another step: adding additional yardage to account that some of the holes will be par 5’s. To account for this, based on conditions, here are the additions of yardage

  • Players who drive it up to 100 yards; add up to 250 yards
  • Players who drive it between 101-225; add up to 750 yards
  • Players who drive it more than 225; add up to 1,000 yards

So do your own math or email me, and I will figure out your real average driving distance by 24 for you and tell you how long your average course should be to have the same chance at par (and fun) tour players do.

    Loved it, great article. We just need course designers to incorporate additional tees to accommodate the appropriate length of course.

    in Germany where I live most courses are longer than 6000m (over 6500 yards) from the mens tees. So nice theorie but no chance ????

    Holy cow, please re-write that first paragraph … I think you showed a LOFT and were riding the struggle bus as an author when tryIng to draw in your audience with that start. Otherwise, very interesting article.

      Who is to say the ratio should be linear or that the ratio should use a driver for the baseline?

      According to trackman, the average pga tour player carries a 6 iron 183 yards. If i use a 6 iron ratio, I would be playing a course 700 yards longer than if I use the “rule of 24”. Why is your method any better than mine?

      This simple example proves the ratio should not be linear.

      You can also prove this to yourself by calculating the ratio between driver and, say, 9 iron, for a pro vs your own distances.

      The pro carries his 9 iron 54% of his carry distance on driver. The slower your swing speed, the larger ratio a 9 iron is to your driver.

      BTW, the average carry distance on tour is 275.

    Great article. Gets me thinking. The problem is determining a driver length average. I know, seems doable enough but I vary between 220 and 310 on the same hole and with the same wind. YES – no bueno. Am a 5 handicap.

    5 iron much more predictable.

    I feel bad for short hitters, such as many ladies. They rarely get the opportunity to have GIR, even with pretty swings. 90% of courses do not have tees for someone who drives it 150.
    For me, distance of the course has less to do with my score than focus and staying on my game plan.

    Thank you for a thought provoking article.

    I’m always curious about the “average drive” as a basis for this type of advice. Is it avg. drive in the fairway? Avg. drive that’s playable (not needing a punch-out from trees, for example)?

    I typically play 6400-6800 yards. I’m 55 years old and an 10.6 hcap, maybe I’m your target for this article, maybe I’m not. If I’m not, then you might not need to read the rest.

    Here’s my barometer for fun, enjoyable golf. If I hit a decently struck drive in the fairway (for me 260), there are few 4’s and 5’s I can’t reach in regulation (or better) with my next shots. The challenge is that sometimes that’s a 4 iron, sometimes that’s a wedge. And if I miss the fairway, I want par to less likely and to use all my skill/creativity to eke one out. I like to play all my clubs, so this challenge is one of my favorite parts of the game. Will I hit a high percentage? Sometimes yes, sometimes no. But to have it be all driver/wedge would remove a significant part of the fun.

    I play one very easy course, par 71, 6570yds and wide open, very little trouble. My 78’s and 79’s there are not nearly as satisfying as my 83’s and 84’s at more challenging courses, and even some of my 89’s elsewhere are more fun than driver/wedge all day.

    Many of us play for the challenge, and going lower by shortening the course isn’t that fun. When I start holding up golfers behind me because I’m taking too long, I promise I’ll shorten things up. But playing shorter just to shoot more 70’s than 80’s isn’t my idea of having more fun with golf. I do completely agree that many should move up. But there are reasons why some of us don’t.

    I like it. I’ve heard a similar thing that I like better. Take your 5 iron carry distance and multiply by 36. Carry it 150? Should play from 5400. 195? 7000 is your distance.

    • Brad M

      Oct 24, 2019 at 12:43 pm

      I think this is a better barometer, the distance variability is reduced with 5iron so you’ll have a more accurate number. This actually shows I should be playing longer than my usual 6600-6800, and I can survive at 7000, but at the moment, that’s usually too much of a grind.

    Its a great insight into driving distance and length of course, it would be interesting to have a formula for SSS or slope! or a personal slope(ability) for example:

    driving distance /2 – handicap = personal slope – slope = score

    just a thought

    I like the rule of 24. But shouldn’t we also account for handicap. My 20+ buddie can crush a drive 300 yards no problem (1 out of 5 tries). But no way should he be playing from the tips.

  12. Bob Jones

    Oct 23, 2019 at 7:24 pm

    I agree wholeheartedly with the rule of 24. My research several years ago produced a number of 25, but that’s close enough.

    What I do now is take the distance of my average (not best) drive, and add on the distance I carry a 7-iron. I play from the tees that give me half the par fours at that combined distance or less.

Watch for players lofting up at altitude at the WGC-Mexico Championship



This week, at the PGA Tour’s WGC-Mexico Championship, we are going to watch some of the best and longest players on the planet play what will effectively be one of the shortest courses on tour.

Now, 7,341 yards is by no means a cakewalk, and there are shorter courses from a pure yardage perspective played on tour—Harbour Town, as an example, only plays at 7,099 yards from the very back. The difference is Harbour Town is played at sea level while Club de Golf Chapultepec is at over 7,500 feet of elevation, and when you factor in the altitude difference between the two courses, they play very differently—more on the math in a moment.

The altitude will also factor in how some players will be setting up their equipment and we could see some adjustments. The most obvious is lofting up the driver or fairways woods to increase carry, which is something Tiger Woods specifically mentioned last year.

The biggest misconception when talking about playing golf at altitude is that the ball doesn’t spin the same in thinner air and players “loft up” to maintain spin. Let’s get into the physics to bust this “spinning less” myth and simplify the science behind playing at altitude,

The golf ball is an inanimate object, and it has no idea it’s at altitude; the air will not have an impact on how much the ball will actually spin. Yes, increasing loft should, by almost every imaginable measure, increase spin but the air it travels through will not change the spin rate.

However, playing at altitude has an effect, Let’s break down what happens

  • Thinner air exerts less drag force (resistance/friction) on the ball. The ball moves more easily through this less dense air and won’t decelerate as quickly as it flies. But note that the faster an object moves the more drag force will occur
  • Less resistance also means that it is harder to shape shots. So you when you see Shot Tracer, the pros are going to be hitting it even straighter (this makes Tiger’s fairway bunker shot last year even more unbelievable)
  • Less force = less lift, the ball will fly lower and on a flatter trajectory

Time for some math from Steve Aoyama, a Principal Scientist at Titleist Golf Ball R&D (full piece here: The Effect of Altitude on Golf Ball Performance)

“You can calculate the distance gain you will experience (compared to sea level) by multiplying the elevation (in feet) by .00116. For example, if you’re playing in Reno, at 1 mile elevation (5,280 ft.) the increase is about 6% (5,280 x .00116 = 6.1248). If you normally drive the ball 250 yards at sea level, you will likely drive it 265 yards in Reno.”

Not every player will be making changes to their bag, and some will instead focus on the types of shots they are hitting instead. When speaking to Adam Scott earlier this week, I was able to ask if he planned on making any changes heading into Mexico the week after his win at the Genesis Invitational.

“It’s very rare for me to make club changes week-to-week beyond playing in the Open Championship and adding a longer iron. The one thing I focus on when playing at altitude is avoiding partial shots where I’m trying to reduce the spin because as spin goes down the ball doesn’t want to stay in the air. I’ve experienced partial shots with longer clubs that end up 25 yards short, and because of that I want to hit as many full shots as possible”

With Club de Golf Chapultepec sitting just over 7,800 feet above sea level, we’re looking at 9.048 or an increase of just over 9 percent. That makes this 7,341-yard course play 6,677 yards (+/- where the tees are placed).

The Gear Dive WITB Edition: Adam Scott



In this WITB edition of The Gear Dive, Johnny chats with JJ VanWezenbeeck and Aaron Dill of Titleist Golf on the ins and outs of Genesis Invitational Champion Adam Scott’s setup.

Adam Scott WITB details below

Driver: Titleist TS4 (10.5 degrees, A1 SureFit setting, 2-gram weight)
Shaft: Mitsubishi Kuro Kage XTS 80 X

  • Scott put the Kuro Kage in play this week. Per Titleist’s J.J. VanWezenbeeck, “Adam Scott switched to the TS4 driver at the ZoZo Championship due to head size, shape, and improved launch to spin ratios. This week, after discussions with Adam, he went to a shaft he had previously played for increased stability. He felt the shaft went a little far and he lost head feel. We went on course with lead tape to get the feels to match up then weighted the head to preferred swing weight after testing.”

3-wood: Titleist TS2 (16.5 degrees, A1 SureFit setting)
Shaft: Fujikura Rombax P95 X

Irons: Titleist 716 T-MB (3-iron), Titleist 680 (4-9 irons)
Shafts: KBS Tour 130 X

Wedges: Titleist Vokey Design SM8 (48.08F, 52.08F, 56.10S), Vokey Design SM8 WedgeWorks (60.06K)
Shafts: True Temper Dynamic Gold AMT Tour Issue X100

Putter: Scotty Cameron Xperimental Prototype Rev X11 (long)

Ball: Titleist Pro V1

Scott marks his ball with dots in the pattern of the Southern Cross, which is featured on the Australian flag.

Grips: Golf Pride Tour Velvet
