There's no way it's longer than 3 feet. 4 to 5 feet, as you suggested, is possible for his sword in ALfheim Online, as that is a huge sword. But despite it's fantasy looks, it remains at realistic proportions, and longswords are historically anywhere from 30 to 45 inches. Or 2.5 to 3.75 feet. But since it's also a game, and it's likely that the weapons would size themselves to the size of the character like they do in many modern games, the sword is probably significantly shorter, due to Kirito not being fully grown yet.
