Arrow Fletching Differences

An arrow's fletching consists of three or four equally-spaced fins glued to the back end of the shaft. These fins serve to stabilize and steer the arrow during its flight. There are many types of fletchings, each of which affects fired arrows in different ways. The choice of arrow fletching is a matter of the archer's individual preference.

  1. Material

    • In the early days of hunting and warfare, arrow fletchings were made from bird feathers. Feathers are extremely lightweight and serve to stabilize the arrow while preventing it from losing too much in the way of altitude over distance. However, they are also expensive and do not hold up well under harsh weather. Many modern-day arrow fletchings are made from flexible plastic "vanes." Vanes are inexpensive and far more durable than feathers, but are also heavier and afford the archer less range.

    Turn

    • Another distinguishing characteristic of fletchings is the turn, or physical arrangement, of the fins. A straight arrangement will prevent rotation and increase speed during flight, but is comparatively less accurate over long ranges. A right-offset arrangement rotates slightly in flight and offers a medium amount of speed and accuracy, but can cause problems with the fletching clearing the bow when fired. A right helical fletch behaves like a propeller, rotating the arrow constantly in flight, but slowing it down.

    Alignment

    • An offset or helical fletch will cause arrow rotation, but different alignment of the fins will cause it to rotate either clockwise or counterclockwise. From a physics standpoint, it makes no difference which way an arrow rotates; it will impact the target with the same amount of force and in the same place. However, right- or left-handedness can play a factor in which alignment an individual archer prefers.

    Size

    • Fletchings of modern-day arrows come in a variety of sizes. Both feathered and plastic fins are sold in sizes of 3, 4 and 5 inches. Larger fletchings have more surface area, and thus offer more air resistance and stability of flight. However, smaller fletchings are lighter, and thus cause less loss of altitude over long distances. The industry standard for arrows is the moderate 4-inch variety, which offers a medium level of weight and stability.
