Stone veneer packs Calculator: measuring notes and method
Separate flats from corners
Enter the area covered by flat veneer pieces and the installed coverage per pack. Corner pieces often have a different ordering unit; measure them separately and follow the supplier’s rule for any flat-area deduction.
Coverage depends on the layout
Check whether the stated pack coverage includes joint gaps. Returns, irregular boundaries and colour blending can change how much usable coverage comes from a pack. Adhesive and pointing material are additional items.
Formula
Packs = net area × (1 + waste ÷ 100) ÷ installed coverage per pack, rounded up.
