1. Total Arrow Length
(throat of nock to end of shaft, in INCHES)
DO NOT include the point.
2. Balance Point Length
(throat of nock to balance point, in INCHES)
Find the arrow’s balance point by locating where it balances perfectly on your finger.
Ideal F.O.C. Ranges by use case
Target Archery
Recommended F.O.C.: 7%–10%
A lower F.O.C. provides a flatter trajectory and faster arrow recovery in flight—ideal for consistent target performance.
Hunting
Recommended F.O.C.: 10%–15%
A moderate F.O.C. offers better arrow stability and deeper penetration, especially important when hitting bone or tough tissue.
High-Penetration / Heavy Setup Hunting
Recommended F.O.C.: 15%–20%+
Higher F.O.C. setups are popular for big game or high-momentum builds (e.g., using heavy inserts or broadheads). They enhance front-end stability and increase punch-through power—but can reduce long-range forgiveness.
Key Considerations
-Too Low: Arrows may fishtail or plane in flight, reducing accuracy.
- Too High: Arrows may drop more quickly and be more affected by wind drift at long distances.
