Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. Horizontal rulers compare the selected spans; vertical brackets also identify height on the artwork. A ruler represents the selected distance or a measurement not visible in this view.

A little perspective

The height of a human is about 1.75 times 1 metre.
