Arrow Length - refers to the length of the arrow shaft. Arrow size - refers to the spine (stiffness) of the arrow. The shaft size is always referring to the diameter of the shaft, the wall thickness of the shaft and the distance that the arrow shaft will flex before it bends or breaks.
Arrow length â To standardize the ratings, the deflection of a static spine is measured with a 28â shaft; but obviously not everyone shoots arrows at that length. If an arrow shaft is cut to a shorter length, then the static spine is actually increased. Conversely, an arrow shaft longer than 28â will have a weaker deflection than what is published. Think of taking two pieces of the same type of string and tying them to posts at different lengths.
