How do I print the ruler at actual size?

Download the PDF, set scaling to Actual Size or 100%, and avoid Fit to Page. Then measure the printed calibration mark.

Why does the 12 inch ruler use Legal landscape paper?

A full 12 inch ruler does not fit across Letter paper at true size with readable margins, so this preset uses Legal landscape.

Does the centimeter ruler include millimeter marks?

Yes. The centimeter presets include millimeter ticks with stronger marks at every centimeter.
