A rapier would most likely have a 30" +/- blade, as it was likely to be needed as a weapon. See the specs for epees and foils in various fencing threads. [Also bear in mind Crocodile Dundee's comment when a thief tells him to give up his cash because he has a knife: "That's no knife, THIS is a knife."] Similarly, a 19" blade would be a laughing stock.
