What is the minimum size for the paths on a labyrinth?
I would say eight or nine inches. Even then, retaining one’s balance while walking begins to be an issue. If you have asked this question because you have limited space for a labyrinth, it is better to use a design with fewer circuits than to make them too small. Usually, this question comes from someone who really wants a Chartres pattern, but only has, say, 25 feet of space. It just can’t be crammed into that space. Better to choose a seven-circuit pattern, such as a classical labyrinth or a Santa Rosa.
