In an article in Volume 2 Number 4 of The Compendium,  I briefly discussed sundial size using the Jaipur, Disney and Augustus sundials.  I compared them using isometric drawings that I made.  On the basis of area occupied by each dial, I calculated the following:

Augustus   -   103000 sq. ft.

Jaipur   -   21000 sq. ft.

Disney  -  11300 sq. ft.

The Guiness Book of Records, the last time I looked, listed the Disney Dial as the world's largest.  When I questioned them about their basis, I received no answer!
