Importance of Proper Arrow Length

Enhances accuracy

Having the proper arrow length is crucial for improving accuracy in archery. When arrows are too short or too long, it can affect the trajectory and stability of the arrow during flight. With the correct arrow length, your shots will be more precise and consistent, resulting in better accuracy overall.

Improves consistency

Consistency is key in archery, and having the right arrow length plays a significant role in achieving consistent results. When using arrows of uniform length, you can develop a repetitive shooting form and release, leading to more consistent arrow flight. This consistency ultimately leads to improved accuracy and better performance.

Prevents injury

Using improperly sized arrows can also pose risks of injury. If the arrow is too short, there is a higher chance of your fingers or hand coming into contact with the arrow rest or bowstring during the release. On the other hand, arrows that are too long may hit the riser or your bow arm, potentially causing accidents or injury. Choosing the correct arrow length ensures a safer and more comfortable shooting experience.

Factors to Consider

Draw length

Draw length is an important factor to consider when determining the proper arrow length. Your draw length is the distance between the bowstring at full draw and the grip of the bow. It is crucial to know your draw length accurately, as it directly influences the length of the arrow you should use. A longer draw length will require a longer arrow, while a shorter draw length will require a shorter arrow.

Bow type and poundage

The type of bow you use, whether it’s a compound bow, recurve bow, or longbow, also affects the arrow length. Different bow types have varying characteristics and requirements in terms of arrow length. Additionally, the poundage of your bow, or the amount of force required to draw back the bowstring, can also impact the arrow length needed for optimal performance.

Desired purpose

Consider your desired purpose for using the bow and arrow. Are you primarily target shooting, hunting, participating in 3D archery, or engaging in field archery? Different purposes may require varying arrow lengths to suit the specific demands of the activity. For example, target shooting may require longer arrows for better stability, while hunting may call for shorter arrows to ensure maneuverability in tight spaces.

Measuring the Correct Arrow Length

Drawing your bow

One basic method to measure your arrow length is by drawing your bow. While maintaining proper form, draw back the bowstring as you would during actual shooting. Have someone mark the arrow from the nock end to the front edge of the bow riser. This measurement will give you a rough estimate of the arrow length needed.

Using an arrow length chart

arrow length charts are widely available and can provide a helpful starting point in determining the right arrow length for your draw length and bow type. These charts typically have a range of draw lengths listed along with corresponding arrow lengths. Find your draw length on the chart and choose the recommended arrow length within that range.

Professional measurement

For more accurate results, consider seeking professional assistance from a knowledgeable archery shop or experienced archers. They can help measure your draw length precisely and recommend the appropriate arrow length based on your individual needs and preferences. Professional measurements can take into account factors such as your shooting form, bow setup, and intended use of the arrows.

Determining Draw Length

Bowing arm measurement

One method to determine your draw length is by measuring your bowing arm span. Stand with your arms straight out to your sides, forming a “T” shape. Have someone measure the distance from the tip of one middle finger to the tip of the other. Divide this measurement by 2.5 to estimate your draw length.

String-to-nose method

Another method involves measuring the distance from the nock point of the arrow to the front center of your nose when you are at full draw. This measurement represents your draw length. Make sure to maintain proper form and have someone assist you in accurate measurement.

Archer’s draw length indicators

Experienced archers may be able to estimate their draw length based on their own physical indicators. For example, if you know that your wingspan is equal to your height, you can use your height as a reference to estimate your draw length. These indicators can be helpful, but it is always recommended to confirm the measurement using more precise methods for optimal accuracy.

Calculating Arrow Length Based on Draw Length

Recommended arrow length formula

A commonly used formula for determining arrow length is to add 1 to 2 inches to your draw length. This additional length accounts for factors such as the broadhead or field point weight and the distance between the arrow rest and the front edge of the bow riser. Adding these extra inches ensures that the arrow extends past the bow when fully drawn, allowing for optimal hand placement and clearance.

Adding or subtracting for specific factors

While the formula provides a general guideline, there are specific factors that may require adjusting the arrow length. For example, if you have a longer-than-average draw length, you may need to add more inches to compensate. Similarly, if you are using a heavy broadhead or heavy arrow shaft, you may need to subtract an inch or two to maintain the correct arrow length.

Considerations for Specific Bow Types

Compound bows

For compound bows, the arrow length is typically shorter compared to other bow types. The let-off characteristic of compound bows allows for a higher poundage at full draw, resulting in increased arrow speed. This increased speed means that shorter arrows are sufficient for achieving accurate shots. However, it is still essential to follow the manufacturer’s recommendations for arrow length specific to your compound bow model.

Recurve bows

Recurve bows generally require longer arrows due to their longer draw lengths and the absence of let-off. When shooting a recurve bow, the full draw length is reached, meaning the arrow needs to clear the front of the bow comfortably. Longer arrows provide more stability and clearance, contributing to improved accuracy and performance.


Longbows have a smoother draw and often require even longer arrows compared to recurve bows. The longer draw lengths associated with longbows necessitate arrows that extend past the bow when fully drawn to ensure proper clearance. Additionally, longer arrows offer better stability and a quieter release, enhancing shooting accuracy and enjoyment.

Considerations for Desired Purpose

Target shooting

For target shooting, longer arrows are generally preferred as they provide greater stability during flight. The longer length helps maintain consistent arrow grouping and reduces the likelihood of the arrow veering off course due to minor inconsistencies in form or release. Target shooters often opt for longer arrows to maximize accuracy and hit the bullseye consistently.


When it comes to hunting, the ideal arrow length may vary depending on the type of game being pursued and the hunting conditions. Generally, shorter arrows are favored for hunting to ensure maneuverability in tight spots. However, it is essential to strike a balance between arrow length and stability to make ethical and effective kills.

3D archery

3D archery involves shooting at lifelike targets in a simulated hunting environment. Similar to hunting, shorter arrows are often preferred for improved maneuverability through the 3D course. However, specific considerations regarding arrow length may vary based on the layout and design of the course, as well as personal shooting preferences.

Field archery

Field archery takes place in varied outdoor terrains with targets positioned at different distances. The ideal arrow length for field archery depends on personal shooting style, the distances involved, and the desired balance between stability and maneuverability. Generally, longer arrows can provide greater stability, while shorter arrows allow for easier movement between targets.

Bare shaft tuning

Bare shaft tuning is a technique used to fine-tune arrow flight and optimize accuracy. It involves shooting bare (unfletched) arrows at a target and analyzing their impact patterns. Adjustments can be made to the arrow length during this process to achieve the desired arrow flight characteristics.

Paper tuning

Paper tuning is another method used to fine-tune arrow flight. It involves shooting an arrow through a sheet of paper and analyzing the tear pattern on the paper. Adjustments can be made to the arrow length to achieve a clean bullet hole-shaped tear, indicating proper arrow flight.

Spine testing

Arrow spine, or stiffness, can affect arrow flight. By spine testing different arrow lengths, you can determine the optimal stiffness for your arrows based on your specific bow setup. Adjusting arrow length during spine testing can help achieve the desired flight characteristics and improve overall performance.

Fine-tuning based on performance

Once you have determined the initial arrow length based on the recommended guidelines and measurements, it is essential to fine-tune the arrow length based on your shooting performance and preferences. Pay attention to factors such as arrow grouping, consistency, and overall shooting experience. Making slight adjustments to arrow length can lead to noticeable improvements in accuracy and enjoyment.
