Crown Molding Calculator

Our crown molding calculator helps you determine the linear feet and number of pieces needed to install crown molding around any room. Whether you're adding elegant trim to a formal dining room or upgrading your bedroom aesthetics, this tool provides accurate material estimates for your project.

Crown molding installation transforms a room by adding architectural interest where walls meet ceilings. The calculator accounts for the room perimeter and standard molding lengths to estimate pieces needed. Most crown molding comes in 8, 12, or 16-foot lengths - longer pieces mean fewer joints but are harder to handle for DIY installation.

This calculator is perfect for homeowners planning their first crown molding project, carpenters estimating materials, and anyone wondering "how much crown molding do I need for a 12x14 room?" Remember to add 10-15% for waste due to corner cuts and mistakes.
