    World's longest slide rule is now 350 feet,  6 1/2 inches set in 2001.

    Prior to that, the record was

    323 feet 9.5 inches in length completed on Nov 11, 1979 by Greg Maggs and Robert Kolstad at the University of Illinois College of Law Building in Champaign, Ill. Guiness Book of World Records, 1983, Sterling Publishing Co, New York, NY USA.

    This was laid out in the hall of my law school by Greg Maggs, the son of my "Contracts" professor.

    Interesting question. Everything is scaled up, including the width of the lines, so even tho the linear spacing between marks is larger, one could argue that the thicker lines oppose a concomitant increase in precision. That being said, I suppose the rule could be re-marked with finer increments making interpolation more reliable.
