ARE TILE SIZES EXACT?

ap_justtiles/node.tpl.php

THE SIZES THAT ARE STATED ARE THE SIZES THAT ARE MANUFACTURED TO, THEY ARE NOMINAL SIZES. MEANING THAT DUE TO THE MANUFACTURING PROCESS AND NATURE OF CERAMIC TILES THE EXACT SIZES CANNOT BE MANUFACTURED CONSISTANTLY AND THAT BATCHES OF THE SAME TILE CAN VARY IN SIZE AS MUCH AS 2MM, WHICH IS WITHIN AN ALLOWABLE TOLERANCE.
