Print to a particular scale

Select File > Print.

Select Print to scale.

4 In the Drawing distance type the width that you would like to be equivalent to the paper width. For example, if you wanted a 1000x800 template to be printed at 1"=100 miles, and you had 10" of printable paper width you would type 10" in the Paper width and 1000 in the Drawing distance.
You can also type, for example, 1" in the paper width, 10' in the drawing distance (for dungeons or cities) to give you a scale of 1"=10’

Select Preview (just to check you've got everthing correct).
