The Fly Hook

  • The size of the fly is determined by the width of the gap. The larger the number, the smaller the fly. For example, dry flies are commonly tied from size #8 (fairly large) down to tiny #22 flies (midges, tricos, etc.).
  • The length of the shank may change from one hook style to another. For example, dry flies are commonly tied on hooks with a “normal” shank length. Streamers are often tied on 3XL (3 extra long) hooks.
