What Do the Numbers on Disc Golf Discs Mean? How to Decipher the Digits

Disc golf, a captivating blend of strategy, precision, and outdoor enjoyment, has gained a dedicated following in recent years. As players step onto the lush greens and wooded fairways, they face an array of discs, each bearing a unique set of numbers. These numbers may seem like cryptic codes to those unfamiliar with the sport. Fear not! In this article, we’ll unveil the meaning behind the numbers on disc golf discs. Whether you’re a curious beginner or a seasoned enthusiast, understanding these digits will unlock valuable insights into disc selection, flight characteristics, and how to harness the power of physics for an optimal disc golf experience. So, let’s unravel the mystery and dive into the world of disc golf numbers, bringing clarity to the complexities and enhancing your disc golf game along the way.

According to the Professional Disc Golf Association (PDGA), around 500,000 of us play disc golf in the United States. With that many people out there, we thought it was time to drop some knowledge for the newbs. Today, let’s answer the question, “What do the numbers on disc golf discs mean?”

Disc golf is for everyone, and there’s no better way to get some exercise while enjoying the fresh air. Now, let’s gain some knowledge.

Disc Golf Course

A disc golf course is a meticulously designed landscape that serves as the canvas for the captivating sport of disc golf. Like traditional golf, these courses feature challenging holes, each with a designated tee area and a target, often called a “basket.” Set amidst various natural elements, including rolling hills, dense woods, and open fields, disc golf courses provide players with a harmonious blend of strategic gameplay and outdoor adventure. The course layout strategically incorporates diverse terrain, elevations, and obstacles, requiring players to navigate through trees, avoid water hazards, and master the art of precision throwing. With varying difficulty levels and distances, disc golf courses cater to players of all skill levels, inviting them to embark on an exhilarating journey of strategy, technique, and camaraderie while immersed in the beauty of nature.

Disc Golf Discs

Disc golf discs, the fundamental tools of this dynamic sport, are a diverse array of flying discs meticulously engineered to traverse varying terrains and execute various flight paths. Crafted from durable materials such as plastic blends, these discs come in a trio of drivers, midranges, and putters. Drivers, built for long-distance flights, boast aerodynamic designs and offer an array of stability levels, from understandable to overstable, to cater to a player’s throwing technique. Midranges exhibit versatility, effortlessly navigating moderate distances with balanced control and accuracy. On the other hand, putters, designed for precision close-range shots, ensure a gentle landing near the target. What truly sets each disc apart, however, are the numeric ratings etched onto their surfaces. These ratings decode a disc’s unique attributes, unveiling its speed, glide, turn, and fade characteristics, thus empowering players to wield the perfect disc for every throw.

What Do the Numbers on Disc Golf Discs Mean?

Let’s jump right in and start to answer the question, “What do the numbers on disc golf discs mean?” The short answer is that the numbers indicate several different things that are important to a golfer — the speed, glide, turn, and fade of the disc.

Unlike ball golf, there are several different types of discs used for various purposes. When you’re shopping for discs, you will see drivers, putters, and mid-range fliers on the shelf. Drivers and mid-range discs will usually have number rankings.


Before we begin, we’re going to briefly go over a few terms that may be new to some of you.

  • Stability: describes the disc’s flight path
  • Understandable: a disc that tends to turn right while in flight (with a right-handed backhand throw RHBH)
  • Stable: the disc’s flight will not turn.
  • Overstable: refers to a disc that will turn left while in flight (with an RHBH throw)
  • Right-hand backhand throw: the traditional throw used by disc golfers (along with forehand and putting)

Disc Manufacturers and Numbering Systems

Different disc manufacturers use different numbering systems. So, at this point, to answer the question, “What do the numbers on disc gold discs mean?” We will have to break it all down.

The four-number system

For the most part, the majority of the discs you’re going to find will use the four-number system. The numbers are usually printed right on the front of the disc going in order from left to right. They stand for speed, glide, turn, and fade.


The first number stands for speed and will be anything from 1 to 14. This number indicates the rate at which that disc will fly through the air. The higher the number, the faster the disc.

Before you assume, though, that you should grab the fastest disc, that’s not always the case. High-speed discs can be very hard to control.


The second number from the left will be a 1 through 7, and it indicates how the disc will glide. Glide is the disc’s ability to maintain height during flight.

If you want a ton of distance from a disc, you want one with a higher glide number. Also, discs with more glide are great for people new to the game. If, however, you’re a seasoned player, a disc with less glide will be more accurate in high-wind situations.


The third number from the left will be a +1 through -5, and it indicates how much the disc will turn while in flight — it’s also sometimes called high-speed stability (HSS). The turn number is the amount the disc will curve immediately after you let go of it.

Generally speaking, when you throw a disc using an RHBH, a rating of +1 means the disc will immediately veer to the left (overstable). A score of 0 means that the disc is stable and should fly in a straight line. And a disc with a negative number means it will start turning to the right.

A disc with a rating of -3 is going to turn a lot more than a disc with a score of -1. Discs rated -3 to -5 tend to be great rollers. A roller is a disc that will turn 90 degrees in the air and land on its side, and roll for more distance — which can be very useful depending on the terrain.


The fourth number on the disc shows how much it is going to fade — otherwise known as low-speed stability. And the amount will be 0 through 5. Now, while the turn indicates how much the disc rotates when it leaves your hand, the fade is all about what the disc does toward the end of its flight.

As a disc slows toward the end of the flight, it tends to curve back in the opposite direction from which it was going before. A 0 in this box means that this disc will fly in a straight path. However, a rating of 6 will mean that your disc will have quite a hook as it slows.

The Vibram system

The number system Vibram uses on their discs is similar to the four-number system with some tweaks. You still have speed, turn, and fade ratings; however, they are on a different scale.

So, the speed rating on a Vibram disc is how fast in miles per hour (MPH) the disc has to fly to achieve the desired flight path. The turn and fade ratings are both on a scale from 0 to 30. A 0 rating means the disc has no flip or turn, while a 30 rating will give you the sharpest angle possible.

Vibram just added a new feature to its discs. On some of them, you will find the expected flight path, when thrown correctly, of course, engraved right on the back.

The Discraft system

Finally, we are finishing up our long answer to the question, “What do the numbers on disc golf discs mean?” with the Discraft system. If you get a disc from Discraft, it will only have one number rating. This ranking pertains to the stability of the disc, and it ranges from -3 to +3.

A disc with a 0 rating is stable. A disc with a ranking of -1 will be understandable and bank slightly to the right, while one with a -3 will be more severe. A rating with a positive number will be overstable and bank to the left.

Now Get out there and Crush Some Chains

And there you have it, folks, the answer to the question, “What do the numbers on disc golf discs mean?” Remember, everyone has a different throwing style.

Disc golf discs never behave the same from person to person. As you learn and grow as a golfer, pay attention to the numbers on your favorite discs and how that translates to what’s happening for you.
