How big should a title block be on a page?
Is there a set height for title blocks, if not what is the standard height that people/ companies use?
It largely depends on the size of paper, size of the drawing, and what you want to include in the title block. My suggestion, is to place a desired drawing in a paper size of your choice. Then start drawing the title block around the drawing, including all relevant fields. What paper size(s) are you using?
