Disc golf
Disc golf flight helper
Interprets a set of flight numbers into a plain description of the shape the disc will fly, and says whether you can throw it fast enough for those numbers to mean anything.
The question this answers: “I throw about 60 metres. Which flight numbers should I be looking for, and what will this disc actually do?”
Result
- Stability
- Overstable
- Expected flight shape
- Mostly straight with a slight right drift, finishing to the left.
- Can you throw it as designed?
- No. At around 65m you can realistically drive up to about speed 7. A speed 9 disc will never reach its turn phase for you — it will fade hard to the left and land short, which feels like bad technique and is actually the wrong disc.
- Speed range that suits your distance
- Up to speed 7
Worth knowing about this answer
- Try a speed 7 disc with similar turn and fade instead. It will very likely go further than this one.

Stability: Overstable. Expected flight shape: Mostly straight with a slight right drift, finishing to the left.. Can you throw it as designed?: No. At around 65m you can realistically drive up to about speed 7. A speed 9 disc will never reach its turn phase for you — it will fade hard to the left and land short, which feels like bad technique and is actually the wrong disc.. Speed range that suits your distance: Up to speed 7
Stability is classified from turn plus fade: a sum at or below −1 is understable, 0 to 1 is stable, 2 to 3 is overstable and 4 or more is very overstable. Suitability compares the disc’s speed rating against a throwing distance band — under 60m suits speed 1–5, 60–90m up to speed 7, 90–120m up to speed 10, and above 120m the full range. Directions are mirrored for a left-handed backhand or a right-handed forehand.
- Flight numbers are manufacturer figures, not a certified standard, and are only broadly comparable between brands.
- The distance-to-speed mapping is an editorial rule of thumb drawn from the widely repeated advice that beginners should throw slower discs. It is a guide, not a measurement.
- A new disc is assumed. Discs become more understable with wear, sometimes substantially.
- Calm conditions are assumed. Headwind makes a disc behave more understable and tailwind more overstable.
- Cannot account for release angle, which changes the flight more than the disc does. The same disc thrown on hyzer and anhyzer produces two entirely different shapes.
- Says nothing about which specific disc to buy, only what a given set of numbers implies.
- Approved-disc status for competition is set by the governing body and is not checked here.
