Calculate each room, subtract only true non-floor areas, add layout-specific waste, then round up to complete packages using actual package coverage.
Measure by room and material
Keep rooms and flooring products separate so the order reflects actual package coverage and dye or production lots.
Match waste to layout
Straight layouts usually waste less than diagonal, herringbone, borders, small mosaics, or rooms with many offsets. Follow manufacturer guidance.
Price preparation and details
Include demolition, disposal, moisture tests, leveling, substrate repairs, moving contents, doors, base, transitions, stairs, delivery, and protection.
