Disc golf discs are characterized by four key flight ratings: speed, glide, turn, and fade. These numbers provide a standardized system for understanding a disc’s flight characteristics. For example, a disc with a speed of 7, glide of 5, turn of -2, and fade of 1 will likely be faster than a disc with a speed of 5, travel further with its glide of 5 (compared to a glide of 3), exhibit a slight right turn (for a right-hand backhand throw) during its high-speed flight, and finish with a predictable left fade.
These ratings are essential for players selecting discs suited to their throwing style and the demands of a particular course or hole. Understanding these numbers allows players to predict disc flight paths and make informed decisions about disc selection for optimal performance. This systematized approach to disc flight characteristics has contributed significantly to the growth and professionalization of disc golf, providing a common language for discussing and comparing disc performance.
