How long should my guitar be?

I have seen alot of bass guitars an alot of other guitars. I know my first one was to small for me didnt know the length ( my old acoustic ) so i do know length is important due to the size of the player. I am six foot tall an 240 pounds. So how long should my bass guitar be i was thinking between 38-43 inches. I would prefur answers from bass players. particularly ones of my stature
