The minimum average length is the shortest average length you will receive in your order. Most manufacturers have minimum average lengths that are quite short (often as short as 2 feet). We offer two length classes on our floors: long and extra long. Either way, our minimum average length is much longer than that of other manufacturers. When comparing prices, be sure to ask the manufacturer about their minimum average plank length and what percent of your floor planks will be longer than the minimum average length. The bottom line: for our price you get longer and larger planks, which are a premium product that adds aesthetic value to your floor.
