Recurve Bow Arrow Speed Calculator
Arrow speed (measured in feet per second, or FPS) for recurve bows depends on several key factors, including draw weight, draw length, arrow weight, and sometimes the bow’s efficiency and materials. Below is a table summarizing the expected speed range based on these elements.
Draw Weight (lbs) | Draw Length (inches) | Arrow Weight (grains) | Approximate Speed (FPS) |
---|---|---|---|
30 | 28 | 400 | 140 – 150 |
30 | 28 | 500 | 130 – 140 |
40 | 28 | 400 | 160 – 170 |
40 | 28 | 500 | 150 – 160 |
50 | 28 | 400 | 180 – 190 |
50 | 28 | 500 | 170 – 180 |
60 | 28 | 400 | 200 – 210 |
60 | 28 | 500 | 190 – 200 |
70 | 28 | 400 | 210 – 220 |
70 | 28 | 500 | 200 – 210 |
Key Considerations:
- Draw Weight: The heavier the draw weight, the faster the arrow generally flies.
- Draw Length: Typical standard is 28 inches, but longer draw lengths increase speed, while shorter ones reduce it.
- Arrow Weight: Heavier arrows are slower but often more stable and penetrate better, while lighter arrows achieve higher speeds.
- Bow Efficiency: Higher quality materials and bow design (like limb efficiency) can increase speed.
This table represents approximate speeds, as real-world speeds can vary based on additional factors like bowstring material, string silencers, and environmental conditions.
