Planning Carpet Area
Carpet area starts with the floor dimensions of each space, usually length × width for rectangular rooms. Add separate room areas instead of measuring the building as one rectangle when walls, alcoves or hallways create an irregular layout.
The calculated floor area is a base quantity, not always the final purchase amount. Roll width, pattern matching, seams, stairs and trimming can require extra material. For ordering, compare the measured area with the supplier’s recommended waste allowance and keep all dimensions in the same unit.
