How much bullnose do I need for my job?
Bullnose needed is calculated by the linear foot, although most bullnoses are not a foot long. To figure bullnose or other trim, take the length of the edge to be covered in inches and divide it by the length of the bullnose (i.e. 8 feet or 96 inches of edge would use 16 pieces of 6 inch bullnose). If the tile does not have bullnose corners available (and most don’t) figure one extra piece of bullnose for each corner to be made. Corners are made by cutting mitered corners with the bullnose just like a picture frame.
