I have a piano roll scanner that I built which can scan rolls as wide
as 13.75 inches.  I am considering enlarging the paper path to
accommodate wider rolls.  Increasing the width to 15.25 inches will be
easier than anything wider as I will have to make many more parts over
again to accommodate anything wider.

The question is, what rolls might be wider than 15.25 inches, and is it
worth the extra effort to be able to scan them?
