1200mm was always the key one for us. When we were being taught all about flag laying back in the 1970s, the 3x2 flags (900x600) were the most popular size laid on highways and a then 4ft level was long enough to mark a diagonal on such a flag, and also to cover two full 600mm wide course, or three courses partially, when checking levels and falls.
I hear what others say about a boat level (handy for checking kerbs are laid with just enough crossfall) and 600mm levels for MH construction, and the super-long levels beloved of brickies, but the 4ft/1200mm level is still my go-to tool of choice.
