Disc Ratings — Understanding Speed, Glide, Turn, and Fade

The Flight Number System Explained

Most discs have four numbers printed on the top, in this order:

Speed | Glide | Turn | Fade

12 | 5 | -1 | 3

Example: Destroyer

Let's break them down one by one to understand what each number means for your game.

Speed (1–14)

Measures how fast the disc must be thrown to achieve intended flight.

Speed Explained

Higher numbers require more arm speed — not necessarily distance.
Speed also correlates with rim width — faster discs have wider rims.
Throwing a high-speed disc too slowly makes it behave more overstable and shorter than expected.

Speed Range	Disc Type	Typical Use
1–3	Putters	Short, accurate shots
4–6	Midranges	Controlled approaches
7–9	Fairway drivers	Long, accurate drives
10–14	Distance drivers	Maximum power, less control

Pro Tip: Throwing a 12-speed disc too slowly makes it behave more overstable and shorter than expected.

Glide (1–7)

Describes how well the disc stays aloft.

Glide Explained

High-glide discs "float," making them great for beginners and tailwinds.
Low-glide discs are more predictable and wind-resistant.
A glidey disc can save distance but exaggerates wind effects.

Glide	Behavior
1–3	Fast drop, very stable
4–5	Balanced flight
6–7	Extra lift and carry

Turn (+1 to -5)

Measures high-speed turn (the disc's initial movement opposite the fade).

Turn Explained

Negative numbers mean more turn (disc drifts right for RHBH).
Positive numbers or 0 indicate stability or resistance to turning.
Beginners often benefit from discs with mild turn (around -2) for extra glide and straight lines.

Turn Value	Description
+1	Very resistant to turn
0	Stable
-1 to -2	Mild turn, added distance
-3 to -5	Flippy, understable flight

Fade (0–5)

Measures low-speed finish — the disc's hook as it slows.

Fade Explained

High fade = strong left finish (RHBH).
Low fade = straighter landing.
Fade determines how much the disc will hook at the end of its flight.

Fade	Behavior
0–1	Finishes straight
2–3	Reliable finish
4–5	Strong hook or skip

Reading a Disc's "Personality"

Combine ratings to predict flight shape and choose the right disc for each situation.

Example Discs

Aviar
2 | 3 | 0 | 1

Putter — Straight, predictable flight

Buzzz
5 | 4 | -1 | 1

Midrange — Straight with slight turn

Teebird
7 | 5 | 0 | 2

Fairway — Reliable fade finish

Destroyer
12 | 5 | -1 | 3

Distance driver — High-speed distance

Rule of Thumb: Low speed + low fade = beginner friendly. High speed + high fade = advanced stability.

Practice

Comparison Drill

Compare 3 discs with different ratings. Throw them flat with the same power. Observe how turn and fade interact — you'll feel the numbers come alive.

What to Look For

Turn timing: When does the disc start turning? How much?
Fade strength: How hard does it finish? How early?
Glide effect: Which disc stays aloft longest?
Speed requirement: Which disc needs the most power to fly correctly?

Common Mistakes to Avoid

Throwing high-speed discs too slowly: Results in overstable behavior and lost distance. Match speed to your arm speed.
Ignoring turn numbers: A disc with -3 turn will turn hard — don't expect it to fly straight.
Overlooking fade: High fade discs finish hard left (RHBH). Plan your landing zone accordingly.
Choosing only by speed: A slower disc can often go farther if it matches your power better.
Not considering glide in wind: High-glide discs are more affected by wind. Choose lower glide for windy conditions.
