The suggested ratio for medium coils is 4:1 through 5:1 so like 16"-20" long 
but that isn't an absolute necessity. People have made longer ones to keep 
topload to primary or strike rail arcing down, a problem that may have kept 
me from maximizing my 3" by 14" coil. I'm sure some other people on the list 
will have more info.
