Trim & Baseboard Calculator

Our trim and baseboard calculator helps you determine the linear feet of material needed for baseboards, door casing, and window trim throughout a room. Whether you're finishing a new construction, renovating, or replacing damaged trim, this tool provides accurate material estimates for your project.

Interior trim gives rooms a finished, polished appearance by covering joints between walls, floors, and openings. The calculator accounts for room perimeter minus door openings for baseboard, plus estimates casing material based on standard door and window trim requirements.

This calculator is ideal for DIY homeowners installing baseboard for the first time, carpenters estimating materials, and anyone asking "how much trim do I need for a room?" or "how many linear feet of baseboard per room?" Add 10-15% for miter cuts and waste.
