Have you installed, or tried to install crown molding but just couldn't get the corners to meet up correctly? Or did you get it right, but it took a lot of time and wasted material? If so, this Crown Molding calculator app is for you! For Do-It-Yourselfers and Professionals alike, this Crown Molding app calculates the miter and bevel angles to use with a miter saw when cutting crown molding for installation. Crown Molding supports both horizontal corners (for typical flat ceilings and mantels, etc) and vertical corners as required for cathedral or vaulted ceilings. Easy-to-understand illustrations are displayed to assist with placing the piece of crown molding on the saw for the perfect cut. No more guessing or wasted material. Cut it right the first time!
