How Long Should My Arrows Be?

If you want to be able to select the right arrows for you and have them cut to the right length, it can be challenging to understand how long your arrows should be if you’ve never had to do it before.

Through a lot of trial and error and a lot of arrows, I’ve come to a very simple conclusion and in this post, I will explain how long your arrows should be and why.

How Long Should My Arrows Be?

Arrow length is optimized at a length that is within the range of plus or minus one inch of your compound bow’s set draw length. For example, if your draw length is 26 inches, your arrow length range is between 25 and 27 inches (optimally). It is recommended to have your arrow extend at least one inch past your rest when your bow is drawn.

  • Have your arrows cut to the same length as your draw length. Extend this by a half inch if your broadhead insert fits flush to the shaft. For half-outs and other inserts that extend .5 inches past the end of your arrow shaft, continue to use your draw length as your arrow shaft cut length.
  • Ensure your broadheads will extend .5″ to 1″ past your arrow rest. This ensures your broadhead will not contact the rest when drawing your bow. This can be critical when using large fixed blade broadheads.
  • Read below to see how to measure arrow length accurately.

For an optimal arrow setup that allows you to tune your arrows easily, you need to know if you are using your arrows primarily for hunting or target shooting. You need to know your draw length. You need to know if you want heavy or light arrows.

You also need to know how your arrow rest is mounted on your bow and what type you are using. Then, you also need to know what type of broadhead you plan to use. All of these factors play into selecting the right arrow length for your compound bow and I will go through them all below.

How to Measure Arrow Length

Arrow length is measured by measuring the distance from the groove in the nock where the bowstring rests (throat of the nock) to the end of the arrow shaft where the broadhead is inserted. This is measured in inches and does not include the length of the broadhead. This is the standard set by the Archery Trade Association (ATA). See the picture below.

Short vs. Long Arrows

Some archers want to have the shortest arrows possible because they want to optimize the speed of the arrow while other bow hunters want longer, heavier arrows that maximize the kinetic energy and penetration capabilities of the arrow. Changing arrow length can affect the spine deflection needed for your specific bow setup.

Shorter arrow setups are excellent for target and 3-D shooting or even if you like to use mechanical or expandable broadheads (see below) for hunting. If your goal is to optimize speed, set your arrow length to your draw length or minus one inch. Ensure you know how your arrow rest is mounted before deciding. See below.

Shorter arrows require stiffer spines. The required spine deflection varies depending on your bow’s IBO Speed, draw length, and draw weight. A longer arrow can be heavier than a short one, but this depends on the make and model. If maximizing arrow weight is a concern, consider using our arrow weight calculator.

Arrow Rests and Broadheads

The type of arrow rest you use can affect arrow length due to the rest’s type or mounting placement. It’s recommended that at full draw, your arrow extends at least one inch past your arrow rest for safety. For instance, a whisker biscuit is easy to manage, especially when using field points or mechanical broadheads.

However, if you use large fixed blade or single bevel style cut-on-contact broadheads, you may not have enough clearance for your rest. Drop-away rests are recommended for these types of broadheads. Ensure your broadheads have enough room between them and the bow’s riser when shooting. If not, you may need to lengthen your arrow or change the rest’s mounting position.

Large, fixed-blade broadheads require at least one-inch clearance from the arrow rest and riser.

*Note: Changing the weight of your broadhead can affect your arrow’s flight and spine deflection. Always ensure your arrows’ weight and length are within range to avoid accidents. Understand the limitations of your arrows by monitoring the vendor’s spine charts and resources.

Example Setup

My bow setup includes a 2022 Bear Alaskan compound bow with a 335 FPS IBO Speed. My Draw weight is 65 lbs. I have a 27-inch draw length. I am using a heavy 605-grain arrow with a 100-grain half-out insert that extends .5″ from the end of the arrow shaft and I use a large fixed blade broadhead (Magnus Black Hornet). My ATA arrow length is 27.75 inches.

Conclusion: How Long Should My Arrows Be?

Now you should have a better understanding of the appropriate arrow length for your needs and hopefully, I’ve answered your question of “how long should my arrows be.” Before cutting arrows to length, familiarize yourself with the arrow buying process, including the spine deflection, type of arrow, arrow weight, and broadhead. Luckily there are arrow vendors out there that can figure this out for you like Sirius Archery.

I always recommend visiting your local archery shop and consulting with an archery professional for assistance. Every situation is unique, and they can provide personalized guidance tailored to your specific needs. With the right arrow length and setup, you’ll be well on your way to enjoying a successful archery experience.
