Fly Proportions: Wet Fly

Proportions:

Head equals eye (1/16- 1/8")

Wing equals hook

Tail equals body length

Beard equals body (should end between the point and the barb)

Body equals shank less head 

Rib: 5 turns

 

As with all fly styles, there are artistic variations on these proportions listed. This is only for the experienced tyer, since there are still ratios that have to be maintained for a uniform look. 

Also keep in mind that some flies when tied according to the original formulas differ from these ratios, usually since they represent a particular insect or food item that varies from the typical one. If in doubt, get a book on tying patterns. My personal favorite is Leiser's book.
