Archery setup quick tips
📏 Measure draw length first
Everything else depends on your draw length. Measure accurately before buying arrows or adjusting your bow.
🎯 Match arrow spine to setup
Arrow spine must match your draw weight and length. Wrong spine = poor accuracy and inconsistent groups.
⚖️ Start with lighter draw weight
Better to shoot 50 lbs accurately than struggle with 70 lbs. You can always increase weight later.
🔄 Calculate FOC for hunting
Front-heavy arrows (10-15% FOC) penetrate better on game. Essential for elk and large animals.
Common archery setup questions
What calculator should I use first?
Start with the Draw Length Calculator. Your draw length determines everything else — arrow length, arrow spine, bow size, and draw weight. Measure your draw length accurately before choosing equipment or adjusting your bow.
How do I know what arrow spine I need?
Use the Arrow Spine Calculator. Enter your bow type (recurve, compound, or traditional), draw weight, and arrow length. The calculator recommends the correct spine range based on industry standards. For quick reference, check the Arrow Spine Chart.
What draw weight should I shoot?
Use the Bow Poundage Calculator to determine appropriate draw weight based on your age, fitness, and experience. Most men start at 40-50 lbs for recurve or 50-60 lbs for compound. Most women start at 25-35 lbs for recurve or 40-50 lbs for compound. Always start lighter and increase as strength improves.
Do these calculators work for all bow types?
Yes! All calculators support recurve bows, compound bows, longbows, and traditional bows. Most calculators let you select your bow type to provide accurate recommendations specific to your equipment.
How do I build a complete arrow setup?
Start by calculating your draw length, then determine the correct arrow spine and arrow length. Next, use the Arrow Weight Calculator to total your components (shaft, insert, nock, vanes, broadhead) and the FOC Calculator to verify front-of-center balance. For hunting arrows, check kinetic energy to ensure adequate penetration for your target game.
What's the difference between hunting and target arrows?
Hunting arrows are heavier (400-600 grains) for penetration and use broadheads. Target arrows are lighter (300-400 grains) for speed and flat trajectory with field points. Use our Arrow Weight Calculator and FOC Calculator to optimize for your discipline. Check the Arrow Selection Guide for specific recommendations.
How accurate are these calculators?
Our calculators use industry-standard formulas from manufacturers' spine charts, AMO standards, and physics-based calculations. Results are accurate starting points for most archers. Always test arrows before buying in bulk, and consult with a certified archery pro shop for personalized recommendations.
