1. What Is Arrow Weight?

Arrow weight is the total mass of an arrow, typically measured in grains (1 grain = 0.0648 grams). It's a critical factor in archery that affects arrow speed, kinetic energy, and penetration.

2. Components of Arrow Weight

The total arrow weight is the sum of all its components:

Where:

• Shaft Weight - The weight of the arrow shaft itself
• Point Weight - The weight of the arrowhead or point
• Insert Weight - The weight of any inserts in the arrow
• Nock Weight - The weight of the nock
• Fletching Weight - The combined weight of all vanes or feathers

3. Importance of Arrow Weight

Details: Heavier arrows carry more kinetic energy and penetrate better but travel slower. Lighter arrows fly faster but may lack penetration. Finding the right balance is key for optimal performance.

4. How to Use This Calculator

Tips: Weigh each component separately (or use manufacturer specifications) and enter the values in grains. The calculator will sum all components for the total arrow weight.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical arrow weight range?
A: Target arrows typically range 300-500 grains, while hunting arrows are usually 400-600 grains.

Q2: How does arrow weight affect bow performance?
A: Heavier arrows absorb more energy from the bow, reducing noise and vibration but decreasing speed.

Q3: What is grains per pound (GPP)?
A: GPP is the arrow weight divided by the bow's draw weight. Most bows perform best with 5-8 GPP.

Q4: Should I include glue weight?
A: The weight of glue is typically negligible, but for extreme precision, you could add 1-2 grains.

Q5: How accurate should my measurements be?
A: For most purposes, ±1 grain accuracy is sufficient. Competitive archers may want ±0.1 grain accuracy.
