HOW DO I MEASURE CORRECT ARROW LENGTH? Correct arrow length is measured from the bottom, inside of the nock groove (deepest point where the string goes into the nock) to the cut end of the shaft, not including the point or point insert.

How do you determine arrow length?

The standard way to measure arrow length is from the back of the point to the throat of the nock. Your draw length and arrow spine will influence your arrow length. If you're a 28-inch draw length and want an arrow that ends at the front of the riser, your arrow length would be around 27 inches.

What does the length of an arrow indicate?

Drawing Force Arrows

The length of the arrow corresponds to the magnitude of the force, with longer arrows indicating forces with larger magnitudes. The direction of the arrow corresponds to the actual direction that the force is being exerted.
