Floor Tile Border Width Calculations


Basic Construction And Carpentry Techniques Home



Floor tile border widths are determined by the following procedure. The tiles are shifted , one at a time, so that the opposite borders are equal in width. Tiles bordering the walls should not be less than 150 mm wide or 1/2 a tile's width. If the distance between the wall and the tile is less than 150 mm or more than 275 mm, a new chalk line is snapped with the centre 150 mm closer to wall. The new borders at the opposite walls will be wider than 1/2 the tile width. If the original border is 70 mm wide on one wall, for example, the 70 mm border plus the 80 mm cut from the tile equals 150 mm. The new border width, after the tile is shifted 150 mm, will be equal to 300 mm tile width minus 80 mm or 220 mm. On the opposite wall, the 70 mm border plus 150 mm equals a tile border width of 220 mm. Each border tile width will include a reduction of 3 to 6 mm to create an expansion clearance between the border tile and the wall. If a 6 mm clearance is used, the border tile will be 214 mm wide and not 220 mm wide. The clearance space can be covered with a cove base after the tile is placed.
