As many years ago, I still encounter the unwanted behaviour of the north Arrow is decreases in size when generating a series of maps.
I have made a map serie with the tool Strip Map Index Feature following long polyline (Dutch ****) and the orientation of the layout is landscape. When I generate the maps to pdf the north Arrow is rotating following the map orientation but decreases in size.
I am using 10.3 and wondering if there is a solution for this behaviour which persist already many years.
Below you can see a screen dump of the first(1) and the last (146) map and the significant different in size of the north Arrow. in map 146 the Arrow is almost not visible anymore
