Moulding Linear Feet Calculator
Professional trim and moulding calculator for construction and woodworking projects. Calculate linear feet requirements, material costs, and cutting optimization with real-time waste analysis.
⚠️ MOULDING INSTALLATION NOTICE
Accurate measurements are critical for moulding installation. Always measure twice and account for inside and outside corners, door/window openings, and waste. Use proper safety equipment when cutting and installing trim.

Linear Feet Calculation
Accurately calculate linear feet by measuring room perimeters and accounting for corners, openings, and waste. Different moulding types require different calculations.
Cutting Optimization
Minimize waste by planning cuts efficiently. Consider standard lumber lengths and plan joints at inconspicuous locations for professional results.
Corner Calculations
Inside and outside corners require different approaches. Account for miter cuts and cope joints when calculating material requirements.
Installation Tips
Proper installation requires accurate measurements, quality tools, and attention to detail. Plan your installation sequence for best results.
Frequently Asked Questions
Measure the perimeter of the room where moulding will be installed. For baseboard, measure around the floor perimeter. For crown moulding, measure around the ceiling perimeter. Subtract door and window openings, then add 10-15% for waste.
Plan for 10% waste on simple rooms, 15% for complex layouts with many corners, and 20% for intricate patterns or if you're inexperienced. Always order extra pieces for future repairs and touch-ups.
Inside corners (like room corners) typically use coped joints for baseboard or mitered joints for crown moulding. Outside corners (like around columns) always use mitered joints. Each requires different cutting techniques and material planning.
Subtract the width of door and window openings from your linear feet calculation. However, if installing case trim around openings, add the perimeter of each opening to your total. Consider the trim style and reveal when calculating.
Common lengths include 8', 10', 12', 14', 16', and 20'. Some specialty mouldings may be available in longer lengths. Plan your cuts to minimize joints and waste by choosing appropriate standard lengths for your project.
Calculate each room separately, then add the totals together. Consider whether rooms connect (shared walls don't need double moulding) and plan your material orders to minimize waste across the entire project.
