Several elements make up the perfect shot; however, getting the correct draw length is the most significant difference for many.

Compound bows are made to be drawn back at an exact distance, in contrast to traditional bows, which can be pulled back from almost any distance. Moreover, the bows have cams. These are pulleys that aid in drawing and releasing the bowstring.

Draw length for your bow has to be adjusted according to your height, which allows you to draw comfortably and with the highest power and precision.

In this article, we’ll explain how to calculate the ideal draw length while going through a detailed look at how to adjust the draw lengths of the compound bow to suit the bow’s strength, power, and height.

How To Measure Draw Length?

There aren’t rules that can guarantee the ideal draw length. Now, if you’re wondering, what is my draw length? It is determined by your height, size, and weight.

That said, a solid calculation exists that many archers have used for many years. It is called the “Arm Span” method.

It is a good draw length measurement starting point to find the ideal draw length for you. Of course, the best length is that at which you are shooting your best. Therefore, be sure to make changes as needed.

Arm Span Method

This method provides a comfortable draw length for most archers. Here’s how to perform an Arm Span:

Stand with your arms stretched out naturally and measure your arm span length in inches.

Ask a person to take your measurement from the tip of your left hand’s middle finger to the end of your right hand’s middle finger.

Divide your length by 2.5, and you’ll have a draw length you can use to draw your compound bow.

How to Adjust your Draw Length?



You can install a broad range of bow cams. They all function to alter/customize drawing length.

The cam you are using will significantly affect how you shoot. The right length can make shooting more enjoyable and improve your shots’ accuracy. So be sure to take note of this vital part of archery.

The following are methods dependent on the composition of the bows for adjusting the draw lengths of a compound bow.

Adjustable Bow Cams

The adjustable cam system is excellent for archers just beginning their careers who aren’t sure of their drawing length. They let the archer alter their length by using a hexagonal wrench without pressing the compound bow. Based on the compound bow, adjustable cams permit archers to adjust anything from 3 to 13 inches.

Draw Length-Specific Bows for Cams

They make use of specific cams that deliver various drawing lengths. In this instance, the archer must purchase the right cam and then mount the cam to alter the draw length.

Changing the cam on a compound bow is a bit difficult as it requires the bow to be pressed. If the archer is not certified to perform the job, the archer must get this done in their local pro shop.

Modular Bow Cams

They have drawn length-specific components that adjust to accommodate archers of different sizes. Modular Cams can be changed using a hexagonal wrench and can be done without pressing the compound bow. Although some companies offer lifetime module modifications, most new modules must be purchased.

Comfortable Draw Length and Weight

Many archers have stated that their most relaxed draw weight and length require using about 75 percent of their strength. If you’re using an overbowed bow, it’ll be only a couple of shots before you’re exhausted, and your practice will end. When your upper and back strength increase, you can extend your draw to make a more efficient shot.

Here is a general overview concerning weight, which will give you an idea of the most common draw weight. Make sure you follow this as a general guideline and adjust accordingly until your bow feels comfortable.

– Children weighing 45 to 70 pounds – between 10 and 15 pounds are the most common draw weight.
– Children aged 70 to 100 pounds- 15 to 30 pounds are the most common draw weight.
– Small-frame girls and boys ranging from 100 to 130 pounds to 30 to 40 pounds are the common draw weight.
– Women with large frames and boys weighing 130-150 pounds – 40 to 55 pounds are the common draw weight.
– Men who weigh between 150 to 180 pounds – 45 and 65 pounds are considered the common draw weight.
– Men weighing 150 to 180 pounds setting bows for hunting or 3d archery – 50 to 70 pounds is the common draw weight.
– Muscular and large frame men – 65 to 80 pounds are the common draw weight.


There’s no one-size-fits-all length, and many prefer to adjust independently. So, follow the above advice and adjust the draw length according to the above guidelines.
