Line width greater than 2.11 mm

I'm drawing a 1 acre lot.
All available line widths (0.00 to 2.11 mm) are basically super thin. I'd like to make a line width of like several inches so that you can have thick-looking lines on a 1 acre lot. Is this possible?

Only in drawing mode the lines appear thin. Switch to Print Preview mode, set the intended scale and you will see how the lines will look when printed on paper or exported to pdf.
