The guideline for rectangular bodies is 4% of the gross width. Think of U-Haul trailers.

My basis for comparison is always the VW Beetle. The original Beetle had a windshield header that rolled 90° to meet the glass. Over the years the windshield was increased in height, later models had the header meet the glass at more like 45°. But the overall contour didn't change.
