Does pipe size affect water pressure?

Increasing the pipe diameter won't change the static pressure (the pressure when no water is flowing). When you open a spigot, however, the water pressure at that spigot decreases somewhat, and because a larger pipe provides a lower resistance to flow, the water pressure will decrease less with the larger pipe.
