CORRECT ARROW LENGTH
Correct arrow length is measured from the bottom of the nock grove to the end
of the arrow shaft (see diagram). Note: Arrow point is NOT included in the
correct arrow length measurement.
Determining Correct Arrow Length:
As a general guide for all target and field archers (including bows
equipped with overdraws), the Correct Arrow Length can be
determined by the following method:
1. Draw your bow using an extra long arrow to your normal full draw.

2. Have someone mark the arrow shaft at least one inch directly in front of
the spot where the arrow contacts the most forward position of the arrow
rest. This is the correct arrow length for you.

Note: Beginners may want to add 1" or 2" to the correct arrow length to
ensure that the arrow will not be too short once their shooting technique
improves, or their technique changes.
Tips

If you don't have a second person to help you measure:

1. You can use your existing arrow or borrow one if you don't have.

2. Tape a clicker on your bow so that the arrow will pass through it at full
draw (just like if you are shooting with a clicker).

3. Measure the length of the arrow tip and distance between the clicker and
the most forward position of the arrow rest.

4. Your correct arrow length can then be calculated using this formula:

* Arrow Length = Measured Distance - Point Length + 1"

* Arrow length in this instance is calculated from the grove of the nock to the
end of the point.

Another way of putting it: Method of Arrow Measurement: The standard AMO
method of measuring an arrow is to find the distance between the groove of the nock (where
the string rests in the nock) to the end of the arrow, not including the insert or tip.
 

We measure and trim all arrows to length using this standard AMO (now the
ATA) method.  If you already have existing arrows which fit your bow properly,
simply measure one by this method and order the same size.  If you are unsure
about what arrow length is appropriate for your bow setup, the next section
may help.
Intro:  Arrows Make a Big Difference!

To bowhunters who select their arrows each season by grabbing a handful from the miscellaneous arrow bucket
at the local super-mart, you may be surprised to learn that shooting custom arrows will greatly improve your
success in the field - for less money than you might think.  If you want reliable and accurate performance from
your compound bow, shooting the proper arrow is very important.  All arrows are not created equal.  An arrow
should be built to match the specific settings and output characteristics of YOUR bow setup, so every shot
launches perfectly from your bow without fishtailing or porpoisng.  An improper arrow will not only fly poorly,
profoundly degrading your accuracy, but it may present a safety hazard for you and your expensive compound
bow.  

There are a number of important considerations to juggle: proper spine, FOC balance, weight, straightness,
fletching material, fletching angle, arrow length, etc., when selecting a set of hunting or 3D arrows.  And if you're
feeling a bit lost, don't worry.  This isn't exactly rocket-science - just a bit of background information you'll need to
know in order to make an informed choice.  These next sections will take you step-by-step through the process of
selecting and ordering arrows with just the right specifications to match your particular bow system.  We hope you
find this help section useful.


Parts is Parts:  Anatomy of an Arrow

Let start with the basics.  The parts of a modern hunting arrow are pretty straight forward, but these parts will be
referred to throughout this help guide.  So before we really get going here, let's take a moment to bone-up on our
arrow jargon.






The foundation of every arrow is the SHAFT, a long hollow tube usually made of aluminum or carbon/graphite
composite materials.  The rear of the arrow is fitted with a small piece of molded plastic called a NOCK, which
allows the arrow to physically attach to the bow's string.  At the front of the arrow is a small aluminum (sometimes
plastic) sleeve called an INSERT.  The insert gets glued into the end of the shaft and provides a threaded hole in
which to screw in the arrow's TIP.  A tip doesn't necessarily have to be a practice point (as pictured here).  A
standard insert allows you to screw-in and use of a variety of tips in the same arrow (broadheads, judo-points,
blunt-tips, field points, fishing tips, etc.).  The last component is the arrow's FLETCHING.  The arrow's fletching is
usually done with colorful parabolic shaped pieces of soft plastic (vanes) or feathers.  In most cases, the three
fletches are glued onto the shaft in an equally spaced circular pattern, with two fletches one color and the the third
fletch a different color (the cock-fletch).  The fletching is very important, as it provides steering and stabilization for
the arrow during flight.
