Spine Chart
Zone Arrow Sizing Chart V2.0. Match your bow weight and arrow length to find your recommended spine. These are general guidelines: for personalised tuning, contact us or your local dealer.
General Arrow Selection Tips
- Point weight. The chart is based on a 100 to 125 grain point. A 150+ grain point may need a stiffer spine; an 80 grain point may need a weaker spine.
- Draw weight. As your actual draw weight rises or falls, the recommended spine changes. Adjusting point weight helps fine-tune the match.
- Arrow length. We use arrow length, not just draw length. For the same spine, a shorter arrow shoots stiffer than a longer one. Recurve archers should match draw weight and arrow length carefully.
- Final results matter. Charts and tuning methods are guidelines. If your bare and fletched shafts group differently, trust the setup that delivers the best results on target.
Special note for Podium Series A/C
Podium Series A/C arrows include 650, 550 and 450 half-spine options. If your setup sits near the lower limit of a spine group, choose the stiffer half-spine size. For example, if your draw weight is just below the next stiffer category, selecting 650 instead of 700 may give better results.
