spacing for canopy support postscolumns
 
spacing for canopy support posts/columns
anyone have any knowledge on how to determine an appropriate
spacing between metal posts or columns which would support a covered walk canopy?

depends on what your loads are and what your beam depth restrictions are to carry these loads to the columns. almost any column spacing is theoretically possible.
width and height of the canopy will play large roles, as they will determine the loads on each column (both downward and lateral). but generally a 15' to 20' spacing should be a reasonable starting point. i've found that the lateral forces (i.e., wind) tend to control the design of these structures, so this spacing will keep your column sizes within reason.
