Sometimes the world of bow hunting and archery can become a little overwhelming. With so many different terms describing different archery equipment, techniques and specs it can often become a maze to the beginner archer starting out on his bow hunting journey.

The smallest amount over or under can significantly change that draw weight to, and in turn will significantly change your arrow speed as it hurdles down range, changing point of impact. Well for starters getting the most energy from any bow, especially compounds, still depends on your draw length. Longer draw length means more energy transferred to the arrow, and shorter means less. Also, when we talk about draw weight being measured to the wall on a compound, this weight can vary as well depending on your ability to hold the same anchor point time after time.

This is where kissing buttons can be a great aid in how to measure bow draw weight that same anchor point time after time. Their are a range of reasons how to paint blue sky and clouds on ceiling draw weight is important, but most notably knowing and using the correct draw weight that suits you will greatly enhance your ability to have the correct technique and form to pull off the perfect shot every time.

Not having and not knowing your draw weight can end up causing more harm then good to your shooting accuracy. As stated above, being just how to measure bow draw weight an inch off of your draw length can change your draw weight by as much as 6lbs in some cases.

This is why anchoring is so important to making sure your on target. Not so much the point that it will change your sight alignment, but the point that it can change the fundamentals of arrow flight significantly resulting in different points of impact due to the draw weight changes.

These scales can come in both digital and manual style scales. So thats a quick run down on how to measure your bow draw weight and why it is important to understand the fundamentals of draw weight and what it means.

In this post we also talked a lot about draw length and how it may affect your overall draw weight. If your unsure on how to find your draw length check out our article here on a couple of different methods of finding draw length.

Dec 14,  · The standard for determining draw weight on these types of bows is measuring the force necessary to pull the bow back to 28inches. Say for example you have a 40 pound recurve bow. This means the draw weight will be 40 pounds when pulled back to 28 inches. If you pull it back a few inches shorter, the draw weight will be less. May 12,  · Measuring draw weight of a bow, the standard of 28 inches and what it means to your draw your draw weight scale here; Nov 03,  · Using a hanging scale and/or a bathroom scale to determine a new bow's draw weight.

The topic of draw weight is often brought up by new initiates into the art of archery. How do we define draw weight? What draw weight should they go with for their first bow?

How does one measure the actual weight of a bow? When measuring the draw weight of a particular bow, there are some important things to consider.

This article examines these considerations. We will discuss how to measure the draw weight of a bow as well as some recommendations for choosing an appropriate draw weight if you are a beginner.

The draw weight of a traditional bow is defined as the amount of force in pounds that is required to draw the bowstring 28 inches from the back of the bow. If somebody tells you that the traditional bow they just purchased is 40 pounds, it means the force on the string at 28 inches is equivalent to 40 pounds. We will discuss more how draw weight applies to different bows in the section: Consideration 2: Type of Bow.

Well, what if an archer has a draw that is longer than 28 inches, or shorter than 28 inches? This is only a rough guide, and depending on the type of bow composite reflex, longbow , draw weights at different draw lengths can vary considerably.

Assume the guideline of plus or minus 2. An archer with a inch draw length will require a force of approximately Hold your arms out parallel with the ground.

Hands and fingers should be outstretched. Measure from the tip of the longest finger on one hand to the tip of the longest finger on the other hand. Divide this number by 2.

The result of this computation will give you your draw length. Note, it is best to use inches as the standard for draw weight is measured at 28 inches. As previously mentioned, drawing a bow shorter or farther than 28 inches will result in a different draw weight at a particular draw length. Also, as previously mentioned, the archer could expect a variance of about 2.

This is only a rough estimation, however. We could then plot this data on a graph. We will designate the y-axis to represent the force or draw weight of the bow.

The x-axis will represent the distance draw length. This data will give us a more accurate representation of how the bow behaves at various draw lengths. The graph is not linear. The draw weight increases at first but at a slower and slower rate until it reaches the inch mark represented by the dotted vertical line. The draw weight then increases at an exponential rate past the inch mark. Can you tell what type of bows they are? Just by looking at this graph, you should be able to make an educated guess.

What sticks out the most when first observing the graph? Well first off the graph uses the metric system with force in Newtons and distance in meters, but these can easily be converted to pounds and inches. The interesting feature here is what happens at about the 0. The draw weights increase quite linearly up to this point, then there is a sudden drop.

This is a result of the cams at the ends of modern compounds which allow for the archer to hold a bow at full draw at a considerably lighter draw weight. Different materials react differently to tension and compression. The types of materials and the way in which they are assembled greatly influence the draw characteristics. The geometry or shape of the bow will also have a great impact on its draw weight at various lengths.

A recurve or reflex horsebow for example, stores more energy at lower draw weights that does a self bow because of its design. The limbs are still under greater tension when the bow is strung and at rest than for a self bow. As we all know, a bow is a device that stores potential kinetic energy. It is derived from the area under the force draw curve of a particular bow.

As can be noted from the above graph that bow A has a greater force at lower draw weights. Many recurve and reflex horsebows exhibit this characteristic.

Many recurves will also exhibit great stacking near the end of their physical draw limit. So, things are not so straight forward, are they? If you are new to archery and considering purchasing a bow, you may be wondering what poundage or draw weight you should get.

It is recommended that you gradually increase draw weight. You should get a light bow to start and work your way up. Some graphs and tables exist to give a rough guide as to what draw weight is suitable but there is one thing these tables fail to consider: the fitness of the archer.

Archers of the past were trained from early childhood with light bows. They gradually increased the size and power of their bows as they aged. As a result, they possessed the necessary musculature to fire very heavy bows.

The draw weights of English Longbows recovered from the Mary Rose had draw weights of pounds up to pounds! Many exercise regiments involving resistance training of some sort could assist the archer in training to help develop the physique required to draw heavier bows. Several bow draw weight scales are available that are designed for this purpose. We recommend CyberDyer Its ergonomic grip and max weight limit of pounds makes it ideal for measuring archer draw weights.

It can also be used to measure luggage weight and other items. Click the images below to view the product on Amazon. A fish scale also provides a similar means to take an accurate measurement.
