IBO Arrow Speed Standard:
| From: | To: |
The IBO (International Bowhunting Organization) arrow speed standard provides a consistent method to compare bow performance across different setups. It calculates arrow speed based on draw weight, draw length, and arrow weight.
The calculator uses the IBO standard formula:
Where:
Explanation: The formula calculates the theoretical arrow speed in feet per second (fps) based on the IBO standard measurement protocol.
Details: The IBO standard allows archers to compare bow performance objectively, helps in selecting appropriate equipment, and provides a baseline for tuning bow setups for optimal performance.
Tips: Enter draw weight in pounds, draw length in inches, and arrow weight in grains. All values must be valid positive numbers for accurate calculation.
Q1: What is considered a good IBO speed?
A: Most modern compound bows range between 300-350 fps IBO rating. Higher values indicate faster arrow speeds.
Q2: How does arrow weight affect speed?
A: Heavier arrows result in lower speeds but carry more kinetic energy. Lighter arrows fly faster but may have less penetration power.
Q3: Why use the IBO standard instead of actual measured speed?
A: The IBO standard provides a consistent baseline for comparison across different equipment setups and eliminates variables like archer form and environmental conditions.
Q4: Does bow efficiency affect the calculation?
A: The IBO standard assumes typical bow efficiency. Actual speeds may vary based on specific bow design, cam system, and other factors.
Q5: Can this calculator be used for recurve bows?
A: The IBO standard was developed primarily for compound bows. Recurve bow speeds are typically lower and follow different performance characteristics.
