MaxiCode is a fixed size symbology. The size of a single symbol including quiet zone is 1.11 inch x 1.054 inch nominal. The quiet zone itself should be the size of one element on all sides. A nominal element size should be a 0.035 inch x 0.041 inch hexagon. By default, all MaxiCode symbols created will conform to specification. Should you need to change the symbol's size for some reason, this can be accomplished by unchecking the Hold to Specifications check box.
