I have a 12x24 tile that is listed as 7mm thick. I am having trouble trying to figure out what tile edge sizing to go with. 1/4'' is converted to 6mm and 5/16 is converted to 7.93mm. I'm using Schluter Rondec for the tile trim. Not sure whether I should go bigger or smaller to prevent a sharp edge. Thanks! via /r/DIY https://ift.tt/2ZcfzdH
