The area estimate uses a joint-inclusive rectangular module and rounds to tiles and then packs. It cannot decide whether individual edge offcuts can be reused. Small rooms or narrow borders may need more pieces than this area method predicts. Compare the rectangular tile layout planner and use actual pack quantities before ordering.

Calculation method
n ≈ ceil(A × (1 + r / 100) / ((w + j) × (L + j))); N = ceil(n / nₚ)Measure. Calculate. Build.
