Measuring & Material Planning Guides
Measure the project first. Plan material quantities separately.
Build on a clear measurement
Record the finished dimensions, divide irregular spaces into nonoverlapping rectangles, and check which surfaces will receive the material. An area measurement alone is not a cutting plan or a complete shopping list.
Keep floor and wall measurements separate. Apply an allowance at the material stage, then use the coverage printed on the selected package. For loose materials, confirm the additional depth and the supplier's delivery units.
Measure rectangle areas, choose a material calculator, or read the calculation methodology.
