There is always going to be a limit to the length of a ruler, unless something clever comes our way. The Consistent-motion Ruler is clever and innovative. It has moving parts that require your thumb and index finger for support. Simply adjust them along the length of the ruler and keep extending the line. Fantastic!

This is brilliant, if the thumb base/slider doesn’t sip out of the ruler’s guide.
