The reliable way to choose arrow spine is to use the current selector or chart from the arrow manufacturer whose arrows you are buying, matched to your specific bow setup. Spine describes how much an arrow shaft flexes, and the right value depends on draw weight, draw length, arrow length, point weight, bow type, bow setup, and release style.
This is not a universal spine chart. Any specific spine number should come from a named manufacturer chart for the exact arrow family, with your real inputs entered. If you are unsure, a qualified archery shop can measure your setup and confirm the fit.

Quick Answer: Use the Manufacturer Chart
To choose arrow spine, gather your bow’s draw weight, draw length, planned arrow length, and point weight. Then enter those details into the current selector or chart for the exact arrow brand and product family you plan to buy. Use that manufacturer’s recommendation instead of mixing values between brands.
What Arrow Spine Means
Arrow spine describes shaft stiffness. When a bow is shot, the arrow flexes as it leaves the string and then recovers in flight. The goal is not to find a random stiffness number; it is to match the shaft to the bow and arrow setup so the arrow behaves predictably.
Static Spine
Static spine is the measured stiffness rating for the shaft. It is the number printed on many arrows and used in manufacturer charts. Static spine is useful because it gives you a starting rating, but it is not the whole story.
Dynamic Spine
Dynamic spine is how the arrow behaves when actually shot. It changes with arrow length, point weight, draw weight, bow setup, and release style. Two arrows with the same printed spine can behave differently if one is longer, uses a heavier point, or is shot from a different bow.
Inputs That Affect Arrow Spine
Manufacturer charts ask for several inputs because spine selection is setup-dependent. Changing one input can shift the recommended spine, which is why simple shortcuts often fail.
| Input | Why it matters |
|---|---|
| Draw weight | More weight generally needs a stiffer match, but not by itself |
| Draw length | Affects the arrow length and energy in the setup |
| Arrow length | Longer arrows generally behave weaker dynamically |
| Point weight | Heavier points generally make the arrow behave weaker |
| Bow type and release | Compound, recurve, finger release, and mechanical release paths may differ |
| Arrow model | Charts are brand and product-family specific |
Draw Weight and Draw Length
Draw weight is the starting point, but draw length helps determine the arrow length you can safely and practically shoot. A change in draw weight can mean your old arrow setup should be checked again.
Arrow Length and Point Weight
Arrow length and point weight are common reasons two similar bows end up with different recommendations. A longer arrow or heavier point can make the arrow act dynamically weaker, so those details must be entered into the selector instead of guessed.
Why Manufacturer Charts Matter
Manufacturer charts matter because each brand uses its own product lines, spine systems, and selection workflow. A value from one brand’s chart does not automatically transfer to another brand’s arrows. Use the chart for the exact arrows you plan to buy.
For example, Easton provides an arrow selector, and Gold Tip provides a spine selector. Use the Easton workflow for Easton arrows and the Gold Tip workflow for Gold Tip arrows. Do not blend the results into a single homemade chart.
For broader archery participation and safety context, USA Archery is a useful reference. For the actual spine number, though, the arrow maker’s chart and your measured setup are the sources that matter.
Beginner Arrow Spine Workflow
- Choose the arrow brand and product family first.
- Measure or confirm your draw weight and draw length.
- Decide the planned arrow length and point weight.
- Open the current manufacturer selector or chart for that arrow family.
- Enter the inputs exactly as the selector asks for them.
- Use that chart’s recommended spine, then have a shop confirm if anything is unclear.
If your draw weight changes later, repeat the workflow. If you cut arrows shorter, change point weight, or move from field points to a different hunting or target setup, recheck the chart instead of assuming the old recommendation still fits.
Keep your measurements written down with the arrows you buy. A simple note with draw weight, draw length, arrow cut length, point weight, insert weight if known, and the chart used can save confusion later. If your groups suddenly open up after a setup change, those notes help you and a shop see whether the arrow match should be checked again before chasing rest or sight adjustments.
Also separate target and hunting setups when the components differ. A practice arrow with one point weight and a hunting arrow with a different front-end setup may not behave the same. That does not mean one is wrong; it means each setup should be checked through the correct manufacturer workflow.
Common Arrow Spine Mistakes
- Using a generic “this draw weight equals this spine” shortcut.
- Mixing chart values between manufacturers.
- Ignoring arrow length or point weight.
- Copying another archer’s setup without matching your measurements.
- Trying to tune around a mismatched arrow instead of fixing the match first.

Frequently Asked Questions
How do I choose the right arrow spine for my bow?
Use the current selector or chart from the manufacturer of the arrows you are buying. Enter your draw weight, draw length, planned arrow length, and point weight, then use the recommendation for that exact arrow family.
Does draw weight alone determine arrow spine?
No. Draw weight is important, but arrow length, point weight, bow setup, bow type, and release style can also affect the recommendation.
Can I use one spine chart for any arrow brand?
No. Use the chart for the exact brand and product family you plan to buy. Manufacturer systems are not interchangeable.
What is the difference between static and dynamic spine?
Static spine is the measured shaft stiffness rating. Dynamic spine is how the arrow behaves when shot from your actual setup, which can change with length, point weight, draw weight, and release style.
Should I ask a pro shop before buying arrows?
Yes, if you are unsure about any input. A shop can measure draw weight, draw length, arrow length, point weight, and bow setup so the chart recommendation starts from accurate information.
Final Recommendation
Choose arrow spine by working through the current manufacturer chart for the exact arrows you plan to buy. Use your real setup inputs, keep each brand’s values separate, and ask a qualified shop when measurements are unclear. That workflow gives you a setup-based recommendation instead of a guess.
