I just joined this forum, & put this app on my phone. Not too sound to stupid, how do you measure your square footage on your floor to have rug, tile, or wood flooring installed. I've always paid to have it installed, might tackle wood flooring in kitchen myself.ive heard that you measure the width & length , & multiplie it. But if there is cabinets on floor, you just use the widest width & length without cabinets? Please help confused!
