How to Choose Arrows for a Compound Bow: Spine, Weight & Length Guide

Choosing the right arrows for your compound bow makes all the difference in accuracy and performance. Whether you’re target shooting or hunting, understanding arrow spine, weight, and length will help you get consistent, reliable results. Let’s break down each factor so you can select the perfect arrows for your setup.

Understanding Arrow Spine

Arrow spine refers to how much an arrow flexes when shot. For compound bows, spine selection is critical because it affects accuracy and arrow flight.

First, check your bow’s draw weight. Most manufacturers provide spine charts that match arrow stiffness to your poundage. For example, a 60-pound compound bow typically needs a 340 or 400 spine arrow.

Second, consider your draw length. Longer draws require stiffer arrows (lower spine numbers) because the arrow stays on the string longer, creating more flex.

Finally, think about arrow point weight. Heavier broadheads or field points require stiffer spines to maintain stability.

Determining Arrow Weight

Arrow weight impacts speed, trajectory, and penetration. Total weight is measured in grains, with three components:

1. Shaft weight – Carbon arrows are lighter; aluminum is heavier.
2. Insert/point weight – Standard field points are 100 grains; hunting broadheads vary.
3. Fletching/nock weight – Smaller vanes add less weight than large feathers.

For target shooting, lighter arrows (350-400 grains) fly faster with flatter trajectories. For hunting, heavier arrows (400+ grains) penetrate better and handle wind more effectively.

Finding the Right Arrow Length

Your arrow length should match your draw length plus about 1 inch for safety. To measure:

1. Draw your bow with an uncut arrow.
2. Have someone mark the arrow 1 inch past your rest.
3. Cut arrows to this length (or have a shop do it).

Longer arrows are more forgiving but slower. Shorter arrows are faster but less stable. Always ensure your arrows clear the rest completely when drawn.

Choosing Arrow Materials

Modern arrows come in three main materials:

• Carbon arrows – Lightweight, durable, and popular for both hunting and target shooting.
• Aluminum arrows – Heavier, straighter, and often used in competitions.
• Hybrid arrows – Combine carbon and aluminum for balanced performance.

Most compound bow shooters prefer carbon arrows for their versatility and durability.

Final Tips for Selecting Arrows

1. Match spine to your bow’s specs – Use manufacturer charts as a starting point.
2. Consider your purpose – Lighter for target shooting, heavier for hunting.
3. Cut arrows to proper length – Always add 1 inch to your draw length.
4. Test different setups – Small adjustments can improve accuracy.
