It all depends on the context. If it's a message you'll repeatedly send to a player, you may aswell stick with 128, because that is the output limit. There are very few places you'll need 256, but you're not bounded by binary numbers, so you could have 200 if you wanted. However, if you were just going to store a players name you would use MAX_PLAYER_NAME (Which I think is 24) as anything else would be a waste!
