The arrows seem like a good measuring point. I am not a professional saddle fitter, and I am also an english rider. . .however I think the rule is that you want the saddle to meet the length of the rib cage, atleast not to go longer/behind the end of the ribcage.
Also the seat size it just the seat, your going to need to add a couple inches for the actual saddle length as a whole, depending on the saddle type for just how many inches to add, you could also ask the seller to measure the entire lenght of the saddle.
hope that helped a little :)
