sport.archery-arrow-drop Calculator
Calculates arrow drop at a given distance from draw weight, arrow mass, and launch angle using projectile motion physics, accounting for fletching drag. Helps archers set sight marks for new distances without shooting dozens of adjustment arrows.
Inputs
Draw Weight Lbs
Body or object weight. For health calculators, usually in kg or lbs.
Arrow Speed Fps
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Distance Yards
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Arrow Weight Grains
Body or object weight. For health calculators, usually in kg or lbs.
