How Long Should A Recurve Bow String Be? (& Measure it Properly)
To determine the ideal bow string size, start with a simple rule: the length should be about three inches shorter than your bow’s total span.
I remember the first time I had to swap out my bowstring; it felt like a puzzle with my archery performance hanging in the balance. Measuring it isn’t just about pulling out a tape measure; it involves understanding the nuances that impact your shot. For archers, especially those just starting, mastering the measurement of the bowstring is important—not only does it ensure safety, but it also optimizes the bow’s function.
Proper length affects everything from how smoothly your arrow flies to how comfortably you can draw and aim. Whether adjusting for a better fit or changing a worn-out bowstring, it’s crucial to measure correctly. You should measure from groove to string groove, following the curve of the bow’s limbs. This isn’t just about keeping your equipment in top shape—it’s about keeping your shots precise and your technique flawless.
Enter the AMO length of your recurve bow (in inches):
How to Measure Recurve Bow String Length
To check the length (under 100 lbs tension), first take off your Recurve Bow String. Measure along the bow’s belly from one groove to another, not counting the grip area. Subtract 3 inches from this length to find the right string size. This is called the AMO length method and is usually seen as reliable. But let’s delve deeper into why accurate measurement matters and how to ensure you’re doing it right.
First, understanding the AMO length standards is crucial. If your bow has the AMO length marked, that’s your cue. Subtract 3 to 4 inches from this measurement; you’ve got the ideal size. But what if there’s no marking? First, measure from the string groove to the next string groove along the curve of the limbs, not including the grip.
Here’s a simple step-by-step to do it correctly:
Why is this method recommended? It’s straightforward and generally the most accurate, ensuring your bow performs at its best safely. Remember, the wrong length can throw off your shot and even damage the bow.
If you’re new to archery or dealing with a special bow, consult a pro at your local archery shop. They can help make sure you’re measuring correctly and choosing the best string for your needs.
Remember, a little expert advice goes a long way in archery!
Choosing the Correct Bow String Length
Often, I’ve seen new archers make the mistake of using a bowstring that seems to fit without considering its actual effect on their bow’s performance. Here’s how to avoid such pitfalls:
Note: This table is for guidance only. Always measure to find your best fit.
| Bow Length (inches) | Recommended String Length (inches) |
|---|---|
| 58 | 54.5 – 55 |
| 64 | 60.5 – 61 |
| 68 | 64 – 64.5 |
| 79 | 66 – 66.5 |
Moving beyond the table, it’s crucial to consider factors that influence the right length beyond just the AMO standards. Here’s what to keep in mind:
Lastly, never stretch a bowstring to make it fit. This can harm both the bow and the string, leading to safety issues and a poor shooting experience. Measure twice, buy once, and always prioritize your bow’s health and your shooting accuracy.
Fine-Tuning Performance Through String Length Adjustments
Let me break down how minor adjustments in string length can significantly enhance your archery, mainly focusing on arrow speed, vibration dampening, noise level, and brace height.
Firstly, consider the impact on arrow flight. A shorter bowstring typically raises the draw weight slightly, which can boost your arrow speed by a few feet per second. This is great for competitive settings where speed is crucial. However, remember that a shorter string also decreases the brace height, which might make the bow less forgiving and stable.
If you’re like me, and consistency is your aim, you might find adjusting for a longer string length beneficial. It increases brace height, enhancing stability and forgiveness, though it might slightly reduce your arrow speed. This setup is ideal for hunting or casual practice.
Most bows perform best with correct brace height within a 1-2 inch range, which can be adjusted by tweaking the string length. If your arrows consistently land a bit low, shortening your string could raise the brace height, potentially correcting the point of impact.
It’s also smart to take material and environmental factors into account. For instance, synthetic materials like Dyneema are less prone to stretching than Dacron, meaning fewer adjustments during seasonal changes. Cold weather can tighten your string, affecting performance, so giving it a bit of slack during winter storage is a smart move.
Types of String Length Adjustments
String length adjustments can help you fine-tune your equipment, whether you’re using a recurve or a longbow.
Safe String Twisting Techniques (For Minor Adjustments)
If you’re noticing that your shots are a bit off, consider twisting your bowstring. For recurves, adding a twist or two is a handy trick for minor adjustments. Each twist shortens the overall length by about 1/16 inch, subtly affecting your brace height. This is crucial because even a tiny adjustment can enhance arrow flight and stability. Remember, though, that it’s a balancing act—too many twists can stress the bow.
Considering Pre-Twisted Strings for Optimal Length
Opting for pre-twisted strings can be a great move for archers looking for consistency right out of the box. These are crafted to maintain a stable length, which means less fussing for you and more time focusing on your technique.
String Loop Length and Its Role in Overall String Length
The loop’s length plays a critical part in the overall string length. Adjusting the loop size allows for more precise control over the bow’s tension and draw weight. This can have a significant impact, especially when you want a smooth, steady pull.
Conclusion
In the end, we can recap the essential points we’ve discussed. Whether you’re a beginner or a pro, remember that the correct length is about three inches shorter than the bow’s length. This is your starting point, and adjustments might be necessary to match your individual draw length and shooting style.
Let’s not overlook the safety aspect. Always handle bowstrings with care. Incorrect handling can lead to accidents. If you need more clarification, it’s wise to consult a professional.
Now, onto the strings themselves.
Opting for pre-made strings based on AMO length can save you a lot of hassle. They are designed to fit your bow perfectly, provided you’ve got the correct measurements.
For those with specific needs, custom strings are a fantastic option. These allow for adjustments not just for length but also for material and thickness, catering to your personal preference and enhancing your bow’s performance. From Dacron strings to more advanced materials, the choice impacts your shooting experience significantly.
To sum up, getting the correct bow string length impacts everything from arrow speed to bow sound. Always start with the recommended AMO length, but don’t shy away from making tweaks to find what indeed works for you.
