Archery Point of Impact Shift Calculator
Calculate how much your point of impact moves per click of sight adjustment.
Works for recurve, compound, and Olympic archery sights.
Archery sights move the point of impact in proportion to the angular adjustment per click and the shooting distance. The same click gives more impact movement at longer distances.
The formula: Shift per click = tan(click angle) × distance
For small angles (typical sight clicks of 0.1–1 MOA): Shift ≈ (click value in cm at 10m) × (distance / 10)
Common sight click values:
- Olympic recurve sights: typically 0.5 mm per click at 18 m (national level), 1 mm per click (beginner)
- Compound target sights: 1/4 MOA, 1/8 MOA, or 1/100 of an inch per click
- Hunting compound sights: 1/4 MOA or 1 MOA typical
MOA to cm conversion: 1 MOA (Minute of Angle) = 2.908 cm at 100 m = 0.2908 cm at 10 m
Worked example (Olympic recurve, 18 m indoor): Sight click value: 0.5 mm at 18 m You need to move impact 3 cm to the right Clicks needed = 3 cm / 0.05 cm = 60 clicks
Rule of thumb: Olympic recurve shooters memorise their click value at their standard distance. Compound hunters use MOA values. Always confirm click values in your sight’s manual — they vary significantly between models.
