The right arrows are matched to your bow and the way you shoot. Three details matter most: arrow length, spine, and bow type. A mismatch can affect how an arrow flies, and an arrow that is too short may create a serious safety risk. Before buying, check your bow’s specifications and measure your setup with help from someone experienced. This guide explains the basics so you can ask informed questions and narrow down suitable options.
Start With Arrow Length
Arrow length is measured from the throat of the nock to the end of the shaft, not including the point. Your draw length helps determine how long an arrow should be, but it is not the only factor. The bow’s design, your point style, and how the arrow rests on the bow can also affect the safe minimum length.
Do not estimate length by looking at another archer’s arrows or by cutting shafts to match your draw length. A qualified shop or coach can measure your draw and recommend a safe shaft length for your specific bow. If you are new to archery or your form is still changing, leave room for adjustment rather than cutting arrows too short.
Understand Spine
Spine describes how much an arrow shaft bends under a given force. A lower spine number usually indicates a stiffer shaft, while a higher number usually indicates a more flexible one. The correct choice depends on the bow’s draw weight, arrow length, point weight, and the shaft material and design.
Use the arrow maker’s selection chart as a starting point, entering the bow’s actual draw weight at your draw length—not just its marked or maximum weight. Changes such as a longer shaft or heavier point can affect the recommended spine. If arrows leave the bow unpredictably or group poorly, have the setup checked before assuming that spine is the only cause.
Match Arrows to Your Bow
Recurve and traditional bows, compound bows, and crossbows can call for different arrow specifications. A compound bow’s cams and release method influence how the arrow responds, while a recurve or traditional setup may use a different rest and shooting style. Crossbows require arrows made for the specific model, with the correct length, nock, and other specifications.
Check your bow’s manual for the approved arrow type, length, and any limits on shaft or point weight. Do not assume an arrow that fits one bow is suitable for another, even if both use similar-looking shafts. When you are unsure, bring the bow’s make and model—or a photo of its specifications—to a knowledgeable archery retailer.
Check Before You Shoot
Inspect arrows before every session. Look for cracks, splinters, bent shafts, loose points, damaged fletching, and worn or split nocks. For carbon shafts, follow the manufacturer’s inspection instructions; damage may not always be obvious. Set aside any arrow that seems questionable, and never shoot it to see whether it still works.
When comparing options, note your bow type, draw weight at your draw length, measured draw length, intended use, and preferred point weight. Ask how the recommended arrow length and spine were selected, and confirm that the nocks and points suit your bow. Cairns Archery Co can help customers check these details in person before choosing equipment.
A safe arrow choice starts with a measured length, a spine matched to the complete bow setup, and compatibility with the bow type. Check the manufacturer’s guidance, inspect arrows regularly, and get help before making changes or cutting shafts. If you want a second set of eyes on your setup, visit a qualified archery retailer and bring your bow details.
