Disc Selection

Reading Flight Numbers

Speed, glide, turn and fade explained.

Why it matters

The four numbers on a disc are the closest thing the sport has to a specification, and reading them properly saves you from the most common equipment mistake there is: buying a disc that cannot do what you want at the speed you throw. They are not perfectly comparable between brands, but within a brand they are reliable.

How to do it

Speed, roughly 1 to 14, is how fast the disc has to be moving to fly as designed. High speed needs a strong arm, not just a strong wish.
Glide, roughly 1 to 7, is how well it stays in the air. More glide means more distance for the same effort, and less control into wind.
Turn, from +1 to -5, is the high-speed behaviour. A negative number means the disc bends right early for a right-handed backhand, and the more negative the more it bends.
Fade, 0 to 5, is the low-speed finish. A higher number means it hooks left harder at the end for a right-handed backhand.
Read turn and fade together: a -3 / 1 disc is a long gentle right-to-straight flight, while a 0 / 3 disc goes left and keeps going left.
Lower numbers all round are more forgiving. A beginner is better served by 5 / 5 / -1 / 1 than by anything exciting.

Common mistakes

Comparing numbers across manufacturers as if they were standardised.They are set by each brand, not by a governing body. A 5-speed from one maker can fly noticeably differently from another’s.

Expecting the printed flight at your own arm speed.The numbers describe the flight at the speed the disc was designed for. Below that, every disc behaves more overstable than the numbers say.

Choosing on turn alone and ignoring speed.An understable disc you cannot get up to speed still fades left. Speed is the gate; stability is the shape.

Key points

Speed = how fast the disc must be thrown.
Turn is high-speed behavior; Fade is the low-speed finish.
Lower numbers are more beginner-friendly.

The drill

Drill · Predict then throw — 5 throws each with 4 different discs (20 total). Before each disc, say out loud what you expect from the numbers — where it will bend and where it will finish. Then throw five and see. Doing this with four discs teaches you how the numbers translate at YOUR arm speed, which is the only translation that matters.
