Count the tiles needed for a floor or wall with waste.
Each tile covers its length times its width, converted from inches to square feet. Dividing the total area including a waste allowance by this coverage rounds up to whole tiles. Tiles are sold as whole pieces and must be cut around edges, so a waste allowance of around ten percent is needed for a realistic order.
