This will give you a pretty good idea of pitch angles on approach. Figure
adding four degrees for a nice flare, and I think you'll find, with wings level, you still have almost 2 degrees to spare (assuming struts compressed....struts extended, you have almost 4 degrees to spare).
FCOM 3.03.22 P3 shows how these margins are reduced with increased bank angle.
In theory, you can scrape metal with FLAPS 3, a significant bank angle at touchdown, and improper flare. However, by following
SOP, a FLAPS 3 landing should not force a meeting and subsequent carpet dance in the chief pilot's office.
Fly safe,
