Stone Veneer Calculator — ft, sqft, cost
How to use this calculator
Select a stone type, enter wall dimensions (length × height), subtract openings (windows, doors), add corner linear feet, and set waste percentage. Results show flat area, corner pieces, mortar bags, metal lath rolls, and total cost.
Stone Types — Natural thin veneer, Manufactured/cultured stone, Fieldstone, Ledgestone. Coverage per box varies by type.
Corners — Subtract corner lf × 0.75 ft from flat area (corners cover ~0.75 ft² per lf).
Mortar & Lath — Optionally estimate mortar bags and metal lath rolls needed.

Stone Veneer Quantity & Cost Estimating
Adhered manufactured and natural thin stone veneer is ordered by the flat box and by the linear foot of outside corner. Corner units wrap roughly 0.75 ft² of face per lineal foot, so this tool subtracts that wrapped area from the flat field before sizing flat boxes — ordering corners and flats off the same gross area double-counts and over-buys. Net area is gross wall minus window and door openings; add 10% waste for straightforward gables and 15% for jobs with heavy cutting around openings, returns, and tight courses.
How to Use
Enter wall length and height in feet and inches, total the opening area, and measure outside corner runs in linear feet. Pick the stone type to set box coverage (manufacturers publish 8–10 ft² per flat box, 6–8 lf per corner box). Veneer is applied over a scratch coat on metal lath; for the structural backup behind it, size the wall with the block wall calculator or the brick wall calculator.
Formulas
Net = (L × H) − openings. Flat field = Net − (corner lf × 0.75). Flat boxes = ⌈Flat field × (1 + waste) ÷ box coverage⌉. Corner lf = corner run × (1 + waste). Scratch/setting mortar runs about 4–5 bags (80 lb) per 100 ft²; cross-check bag yield with the mortar & grout calculator. Diamond metal lath covers roughly 70 ft² per 2.5×28 ft roll.
FAQ
Do I deduct openings? Yes — only the veneered face is purchased, so subtract full window and door areas. Why order corners separately? Corner units are L-shaped, priced per linear foot, and cannot be cut from flats. Foundation and footing? A veneer ledge or concrete footing supports the assembly — size it with the concrete bag calculator or a concrete grade beam. Work follows TMS 402/602 and ASTM C1670 for manufactured units.
On install day
Three line items estimators miss on stone veneer. Corners run short first — corner units are priced per lf and ship 6–8 lf per box, so a chimney with eight 10-ft runs (80 lf) is 10–14 boxes before waste; under-ordering corners stops the job because flats cannot be cut to an L. Substrate — over wood frame you need a WRB plus 2.5 lb diamond metal lath nailed every 6 in. into studs (TMS 402 §12.4); over CMU or poured concrete the scratch coat bonds directly and lath drops off the takeoff. 2025 budget — manufactured flats run $8–14/ft² and corners $14–25/lf delivered; natural thin veneer is $15–30/ft². Always add a separate line for the scratch and setting bed mortar and for the structural backup — sized with the block wall calculator or retaining-wall calculator when the veneer faces a freestanding wall.
