Using a Scale Ruler is one of the most important skills share by both designers and technicians. This video shows my demonstration on how to use a Scale Ruler pdf (free) and a plastic scale ruler to start measuring and marking a Scale Ruler Worksheet my students need to complete for class.

Note about the PDF scale ruler and the worksheet:

These scale rulers are certainly not as accurate as the plastic versions that you should actually use. Please check your settings on your computer before printing these out to make sure that you are printing the page at 100%. If your printer output is set to “fit to page,” these will be significantly off.
