If the area I’m doing is 650 Square feet do I need 650 quarter round material? I thought it was to cover door ways and gaps?

Hello! Square feet is the measure of an area. You need to measure for linear feet for your quarter round molding needs. Linear feet is the measure of length. Order enough of the quarter round molding in linear feet for the areas where you need/want the molding. Thank you for your interest in Pergo. - Shanna
