In todays world with various digital methods providing anything you want the question is a little more difficult to handle. Add to it that certain aging members like me can no longer read some of the miniscule text that some draftspeople still can read. In my 35 years of experience I would say that the min size of text for a 22"x 34" sheet being reduced by 50% to fit on a 11x17" printer should not be less than .09" better is .10" as this becomes .045 or .05 respectively. Also gone from most drafting knowledge is that it is smart to leave a min of 2" clear space between objects, plans, sections etc for notes and dimensions. That is to mean you have to leave 2" x your scale of your drawing if anotating in model space. When I have some more time I may write a book on how to set standards for different type of drawings.....hmmm. Oh yes if you plan to print half scale or approximately half scale you need to put a scale bar on your drawing which indicates that tif plotted as full scale the scale bar represents 4" in length. ie "This bar scales 4" on original size".....Of course if metric place 100mm bar, and so on. Thats cuz some folk in civil do drawings in meters and feet, not in inches and millimetres.
