Bow Poundage Calculator
Find the right draw weight for your body and experience.
Essential for choosing your first bow or upgrading.
Based on age, strength, and intended use.
💡 Tip: Start at the low end of your range. It's easy to increase draw weight later, but bad form from a too-heavy bow is hard to fix.
Example recommendation
A complete beginner with average fitness should start by testing a light, controllable range, not by choosing the heaviest bow they can pull once. The calculator gives a conservative trial range and recommends starting at its lower end.
The result is a fitting aid, not a strength test or legal hunting minimum. If you cannot draw smoothly with normal posture and repeat good shots without strain, reduce weight.
🎯 Ready to buy your first bow?
Browse compound bows at Amazon, recurve bows on Amazon, or traditional longbows at Optics Planet. Look for adjustable draw weight ranges (e.g. 40–60 lbs) to grow with your skills.
Understanding bow draw weight
What is draw weight?
Draw weight is the force required during the draw cycle, expressed in pounds. A compound reaches a peak weight and then lets off near full draw; recurve and longbow weight generally increases as draw length increases.
Why starting weight matters
More weight is useful only when the archer can control it. A lighter bow that supports relaxed posture, repeatable anchor, and clean execution is a better training tool than a heavier bow that forces leaning, shrugging, jerking, or early fatigue.
Mathews' beginner guidance recommends correct equipment fit and starting with a lower draw weight, then building strength through practice. This calculator follows that conservative approach.
Draw weight, speed, and hunting
Increasing draw weight can increase stored energy and arrow speed, but the exact change depends on the bow and complete arrow setup. Use our Arrow Speed Calculator and Kinetic Energy Calculator to measure the resulting setup rather than assuming a fixed FPS gain per pound.
Draw weight recommendations
Youth archers
Youth draw weight should follow physical development, instruction quality, and repeatable form rather than age alone. USA Archery recommends a light bow for most 12–15-year-old archers and older beginners during strength/endurance training. For younger children, qualified instruction and very light equipment are especially important. For youth-specific equipment sizing, use the Youth Bow Calculator.
Use the calculator range as a conservative trial window and begin at the low end. Refit the archer as growth and technique change.
Adult beginners
There is no reliable universal “men should shoot X / women should shoot Y” starting weight. Mathews' beginner guidance emphasizes correct equipment fit and starting with a lower draw weight, then building strength through practice. Individual strength, shoulder health, technique, bow type, and let-off matter more than demographic averages.
Experienced archers
Experience can justify testing a somewhat higher range, but only if full-draw alignment and shot execution remain controlled. Increasing weight should not create shoulder elevation, leaning, jerking through the draw cycle, or loss of accuracy.
Older or returning archers
There is no automatic age-based subtraction that fits everyone. If returning after a layoff or managing reduced strength or mobility, start lighter and rebuild gradually. Shoulder comfort and repeatable form are better guides than age alone.
Draw weight for hunting
Legal minimums vary by jurisdiction
Do not use a nationwide “40 lb minimum” as a legal rule. Hunting regulations vary by state, province, country, species, and sometimes equipment type. Check the current regulation where you will hunt.
Hunting is a complete-system question
Easton notes that ethical bowhunting performance is not determined by draw weight alone. Draw length, arrow weight, bow efficiency, broadhead type, shot distance, shot placement, and the archer's form all matter. A reputable technician can help match a lower-poundage setup with an appropriate arrow and broadhead.
Never raise draw weight just to satisfy a calculator
If the weight required by local law is more than you can draw smoothly and control from realistic field positions, build strength before hunting or choose another legal method. Do not sacrifice form to reach an arbitrary number.
Signs your draw weight may be too high
⚠️ You cannot draw smoothly
Leaning back, raising the shoulder, jerking through the draw, or needing a “sky draw” are strong signs that the bow is too heavy for productive practice.
⚠️ Form collapses as the session continues
If anchor, bow-arm alignment, release, or group size deteriorates as you tire, lower the weight or shorten the session before practicing poor movement patterns.
⚠️ Pain, not normal exertion
Stop if shooting produces sharp, persistent, or worsening shoulder pain. A calculator cannot assess an injury; reduce load and seek qualified medical advice when appropriate.
✅ The controllable-weight test
The right range lets you draw with normal posture, settle at full draw with stable alignment, and repeat good shots without fighting the bow. There is no universal 30- or 60-second hold rule required to prove fit.
How to increase draw weight safely
Increase only after the current weight is controlled
There is no universal calendar such as “add 5 lb every 3 months.” Progress when you can draw smoothly, hold with stable alignment, and complete normal practice without pain or deteriorating form.
Use small, model-approved changes
On adjustable compound bows, stay within the manufacturer's adjustment instructions. Mathews, for example, specifies model-dependent limb-bolt limits and tells owners to keep both limb bolts adjusted equally.
Build archery-specific strength
Regular shooting with a manageable bow develops the specific movement pattern, but stop before fatigue destroys form. USA Archery also publishes structured strength and endurance exercises for archers.
Bow poundage calculator FAQs
What draw weight should I start with?
Start with a weight you can draw smoothly using normal posture and repeat for a full practice session without pain or collapsing form. This calculator provides a conservative test range, but a qualified coach or bow technician can fit you more precisely.
What draw weight do I need for deer hunting?
There is no single draw weight that is both legal and ideal everywhere. Check the current law where you hunt. Easton also notes that draw length, arrow weight, bow efficiency, broadhead type, shot distance, shot placement, and form all contribute to an ethical setup. Use our kinetic energy calculator for the physics, not as a legal pass/fail test.
Can draw weight be too high?
Yes. If the bow forces you to lean, shrug, jerk through the draw, shorten your hold, or lose repeatable form, the weight is too high for productive shooting even if you can pull it once.
How do I know if my draw weight is too heavy?
Watch the shot process rather than a stopwatch rule. Warning signs include struggling to start or finish the draw, shoulder elevation, leaning backward, shaking, collapsing at full draw, pain, or accuracy deteriorating as the session continues.
Should women shoot lighter draw weight than men?
Draw weight should be fitted to the individual rather than chosen from a gender rule. Strength, shoulder health, technique, experience, bow type, let-off, and the intended discipline are more useful fitting inputs.
How long until I can increase draw weight?
There is no fixed timetable. Increase only after the current weight is controlled with good alignment and repeatable accuracy and normal practice does not create pain or form breakdown. Use small, manufacturer-approved changes.
Is 70 lbs too much for deer hunting?
It may be appropriate for an experienced archer who controls it comfortably, but it is not required simply because the target is deer. Legal requirements vary, and a lower draw weight with a properly matched arrow and broadhead can be an effective setup. Do not sacrifice form to reach a heavier number.
Do compound bows have adjustable draw weight?
Many do, but the adjustment range and procedure are model-specific. Some manufacturers permit limited limb-bolt adjustment; others use different limb or module configurations. Follow the exact bow manual or an authorized retailer.
