Many factors come into play when determining the speed at which an arrow leaves your bow, and how much kinetic energy it retains when it reaches its target downrange. One of the most crucial of these factors is a bow’s draw weight. This naturally inspires many archers to question what compound bow draw weight is right for them.
If you find yourself with a similar question of this nature, the following information will not only assist you in coming to a well-researched conclusion but will assist you in better understanding how such a decision is made.

How Much Draw Weight Is Needed?
The amount of draw weight that is needed centers around what is required to achieve ample arrow penetration, leading to a quick, clean, and efficient kill.
Contrary to popular belief, arrow speed itself does not dictate an arrow’s ability to penetrate its target. Read all about the best beginner compound bows!
Instead, kinetic energy is the standard figure that is used to determine an arrow’s level of penetration. The formula for figuring the kinetic energy produced by your bow’s current set-up is as follows:
Fps2 X Weight of Arrow / 450,240 = Arrow’s Kinetic Energy
The following factors all play a large role in determining a particular bow’s kinetic energy.
Draw Weight
As a bow’s draw weight increases, so does its potential to create. This stems from the fact that draw weight and other factors such as arrow weight directly influence a bow’s observed arrow speed.
This is important since arrow speed is one variable in the equation used to figure kinetic energy.
Draw Length
With every additional inch of draw length, a bow’s arrow speed increases by approximately 10 FPS (Feet-Per Second).
This makes draw length a valuable figure in the kinetic energy equation for much the same reason as draw weight. This stems from the fact that kinetic energy is ultimately dictated to a point-by-arrow speed.
Brace Height
Brace height is another factor relating to a bow’s kinetic energy. As we have already learned, arrow speed is not the only dictating factor of kinetic energy but plays a large role.
The shorter a bow’s brace height, the faster shooting it typically is. This is because short brace heights allow an arrow to remain in contact with the bowstring longer.
Arrow Weight
The other value that must be considered when figuring out kinetic energy is the weight of your arrow. The gains produced by the previous three elements can be enhanced or negated, depending on the weight of the arrow you shoot.
Even a bow with a short brace height, long draw length, and heavy draw weight can suffer from the effects of an overly heavy arrow.
How Do You Know If Your Draw Weight Is Too Heavy?
Although conventional wisdom would lead most to believe that the heavier your draw weight, the more efficient bowhunter you will be, this couldn’t be further from the truth.
As draw weight increases, so does the strain on your muscles as they attempt to overcome the significant force that this requires.
Whether you are a bowhunter, target archer, or both, shooting too much poundage can negatively impact every aspect of your experience.
This can ultimately lead to confidence issues and a barrage of frustration. No amount of kinetic energy comes as any benefit if you cannot shoot your bow with precision.
When shooting too much poundage, target archers become more susceptible to target panic. When this occurs, archers become anxious about the shot process itself and punch their release rather than triggering it slowly.
This leads to poor accuracy and worsening anxiety.
When hunting with a bow that features an excessively high draw weight, it often becomes difficult to hold at full draw for the extended periods that are sometimes required before the perfect shot becomes available.
Additionally, muscle tightness due to frigid temperatures often makes drawing a bow much harder than it would be in fair weather, especially with the exceedingly high draw weight.
There are several notable signs that an archer can follow to tell if their draw weight is set too heavy.
1.) If a bow cannot be smoothly drawn without aiming upward, jerking backward on the bowstring, or straining excessively, its draw weight likely exceeds what it should be.
Ideally, a bow should be able to be drawn and fired over 20 times in a row, with only minimal fatigue.
2.) If you notice pain in your shoulders, back, or chest at any point when shooting your bow, it is quite likely that you are pulling an excessive amount of draw weight.
The regular shooting of a bow that is set to an excessively high draw weight can often cause damage to joints, ligaments, and tendons.

Heaviest Compound Bow Draw Weights
In today’s market, 70-pounds is typically the average top-end on draw weight. However, several companies manufacture and sell bows with limbs that are rated for up to 80-pounds of draw weight.
In the past, there have been a limited number of bows that were specified for a draw weight of up to 100 pounds, although this is quite rare.
Selecting The Perfect Draw Weight
Above all other factors, the best draw weight is one that you can draw smoothly, hold at full draw for as long as needed, and shoot comfortably.
The inability to complete any of these three tasks satisfactorily will create difficulty, and limit an archer’s enjoyment, whether target shooting or bowhunting.
A Handful of Essential Points to Note:
- When hunting game animals, it’s vital to prioritize shot placement for a successful and ethical outcome.
- Aiming for the chest cavity, where the animal’s vital organs reside, is the key to a quick and humane kill.
- For larger game like antlered deer, having a comfortable draw weight on your bow is essential.
- Selecting a draw weight that aligns with your physical strength and shooting prowess ensures the right balance of comfort and power to pierce the game animal’s chest cavity.
- While a bow’s maximum draw weight may be alluring, it’s not always necessary. Instead, strive for a peak draw weight that allows you to maintain proper form and precision.
- Heavier arrows, like aluminum ones, can also enhance penetration and boost the chances of an ethical shot.
- Bow hunters and crossbow hunters alike should opt for fixed-blade broadheads, which offer consistent cutting and reduce the risk of deflection upon impact.
- Modern compound bows enable higher draw weights and swifter arrow speeds, but be aware of potential minimum poundage requirements set by regulations to ensure ethical hunting practices.
- No matter the draw weight you select, maintaining proper form is crucial for accurate and effective shooting.
- Regular practice and good shooting mechanics are key to honing your skills. Some hunters favor mechanical blades on their broadheads because they open upon impact, creating larger wound channels.
- However, it’s important to take into account the average draw weight you can comfortably handle and choose broadheads accordingly.
- By concentrating on shot placement, draw weight, arrow choice, and adhering to ethical guidelines, hunters can enhance their odds of a successful and humane hunting experience.
