Inputs

Section 1: Building & Corners

Overall Wall Height

ℹ️Used with Outside Corners to size corner linear footage — use the tallest point a corner run must cover, e.g. the full two-story height where applicable. Each wall section's own height (below) drives its own net area.

Outside Corners

ℹ️A simple rectangular house has 4 outside corners; add more for an L-shaped footprint, bay windows, or bump-outs. Corner linear footage reduces the flat panel order, since corner units physically replace that strip of flat veneer.

Every window and door entered here is fully deducted from this wall's net area — adhered veneer units are not a reusable cut-off material, so there is no "normal opening absorbed into waste" exception.

Each row is a separate wall elevation — up to 20 sections, combined into one total. Leave window/door counts at 0 for a blank wall.

Section 3: Veneer, Substrate & Joints

Veneer Type

Covers adhered/thin veneer only — not full-thickness anchored clay brick veneer with ties and an air gap. See the FAQ below for the scope boundary.

Substrate Type

Frame + Lath needs metal lath and a scratch coat behind the veneer, plus a required weep screed and lath fasteners.

Framing Spacing

▾

ℹ️Sets the lath fastener grid's horizontal spacing — confirm the required spacing for your local code/sheathing before finalizing.

Joint Style

Grouted joints need a grout bag quantity for the visible mortar joints between units.

Section 4: Advanced Product Figures

These default to commonly cited figures for the selected veneer type — leave blank to use the default, or enter your own product's published numbers.

Flat Box Coverage

ℹ️How many square feet of flat panel one box of your chosen product covers.

Corner Box Coverage

ℹ️How many linear feet of outside corner one box of corner units covers.

Corner Deduction Factor

ℹ️How much flat panel one linear foot of corner removes from the flat order. Commonly cited 0.5-0.75 — manufacturers disagree, so confirm against your product's installation guide.

Unit Weight

ℹ️Saturated installed weight of the veneer units alone, per sq ft — used for the total weight estimate and the 15 lb/sq ft lightweight threshold flag.

What Is a Brick Veneer / Stone Veneer Calculator?

If you're pricing a thin brick veneer or manufactured stone veneer cladding job, this calculator answers how many flat panel boxes, corner unit boxes, scratch coat and setting mortar bags, grout, lath, and fasteners you need from your own wall sections, window and door openings, veneer type, substrate, and joint style. It returns flat and corner box counts, scratch coat and setting mortar bags, grout bags (if grouted), self-furring lath sheets, lath fasteners, weep screed, installed weight, and an optional material + labor cost.

It is built for homeowners, masonry and siding contractors, and estimators pricing an adhered veneer cladding job on a house with one or several distinct wall elevations, each with its own size and openings.

What this calculator covers — and what it doesn't:

This calculator covers ADHERED/THIN veneer only: Thin Brick Veneer (clay units about 3/8-1 in thick) and Manufactured Stone Veneer (lightweight concrete), both installed the same way — over a weather-resistive barrier, metal lath, and a scratch coat on a frame wall, or bonded directly to masonry/concrete with setting mortar alone. It does NOT cover full-thickness ANCHORED clay brick veneer (4 in nominal units with corrugated metal ties into the studs, a 1 in air gap, flashing, and weep holes) — a structurally different, far heavier masonry-veneer assembly. If that's what you need, use this site's Brick (Masonry Wall) Calculator instead.

The headline differentiator — corner units reduce the flat panel order:

Corner units physically replace the flat panel that would otherwise cover that strip of wall, so this calculator subtracts (outside corner linear footage x a deduction factor) from the net wall area before computing the flat panel box count — most competitor tools skip this step entirely and simply over-order flat panel. Meanwhile, the lath, scratch coat, setting mortar, grout, and weep screed are all driven by the FULL net wall area, since those materials are consumed across the entire wall surface regardless of whether a given square foot ends up under flat panel or a corner unit.

Applicable standards:

ASTM C1780 (Installation of Adhered Manufactured Stone Masonry Veneer) and the Masonry Veneer Manufacturers Association (MVMA) Installation Guide govern lath, scratch coat, and setting mortar requirements, which should always be confirmed against the current edition and the specific product's own evaluation report (e.g. an ICC-ES ESR).
Local building code (e.g. weather-resistive barrier and weep screed requirements) may differ from the general figures used here and should always take precedence.
This calculator estimates material quantity and cost only, not structural wall design or an engineered seismic weight review.

How the brick/stone veneer calculation works

Net area comes from gross wall area with EVERY window and door fully deducted; the flat panel order is then further reduced by the corner deduction, while every other material (lath, scratch coat, setting mortar, grout, weep screed) is driven by the full net area.

Step 1 - Net area and corner linear footage

Net Area = SUM(Wall Width x Height) - SUM(ALL Window Area + ALL Door Area)

Corner Linear Ft = Outside Corners x Overall Wall Height

Waste-Adjusted Net Area = Net Area x (1 + Waste % / 100)

Every window and door is fully deducted — adhered veneer units are not a reusable cut-off material, so there is no partial-deduction exception. Corner linear footage comes from the building's outside corner count and the tallest run a corner must cover.

Step 2 - Flat panel order (the corner deduction)

Deducted Flat Sq Ft = Corner Linear Ft x Corner Deduction Factor (default 0.75 sq ft per linear ft)

Real Flat Panel Sq Ft = MAX(Net Area - Deducted Flat Sq Ft, 0)

Flat Boxes = CEIL(Real Flat Panel Sq Ft x Waste Multiplier / Flat Box Coverage)

Corner Boxes = CEIL(Corner Linear Ft x Waste Multiplier / Corner Box Coverage)

Corner units physically replace the flat panel that would otherwise cover that strip of wall. The deduction factor is genuinely manufacturer-dependent (commonly cited 0.5-0.75 sq ft per linear ft) — this calculator defaults to 0.75 but exposes it as an editable advanced input.

Step 3 - Lath, scratch coat, setting mortar, grout, and weep screed (driven by the FULL net area)

Scratch Coat Bags = CEIL(Waste-Adjusted Net Area / 11 sq ft per bag) — Frame + Lath only

Setting Mortar Bags = CEIL(Waste-Adjusted Net Area / 15 sq ft per bag) — both substrates

Grout Bags = CEIL(Waste-Adjusted Net Area / 40 sq ft per bag) — grouted joints only

Lath Sheets = CEIL(Net Area x 1.06 lap factor x Waste Multiplier / 18 sq ft per sheet) — Frame + Lath only

Weep Screed Pieces = CEIL(Total Wall Base Width x Waste Multiplier / 10 ft stock length) — Frame + Lath only

These all consume material across the ENTIRE net wall area regardless of whether a given square foot ends up flat panel or a corner unit — changing the corner deduction factor never changes any of these five quantities, only the flat/corner box split. Direct-to-Masonry needs no lath, scratch coat, fasteners, or weep screed at all.

Step 4 - Fasteners and weight

Lath Fasteners per Wall = (Stud Lines Across Width) x (Nail Lines Up Height) — Frame + Lath only

Installed Weight (units only) = Net Area x Unit Weight (lb/sq ft)

Lath fastener grid is the same fencepost-counted shape as this category's Stucco Calculator. Installed weight covers the veneer units themselves (both flat and corner together cover the whole net area one way or another) — it does not include mortar or scratch coat weight, which is disclosed in the Limitations below.

Real-World Brick/Stone Veneer Calculation Example

This example uses the active calculator inputs above and follows the same steps from the formula section.

Input Values Used

Input	Value	Why it is used
Wall Sections	1 section(s)	Sums to the total net area (openings fully deducted)
Veneer Type / System	Thin Brick Veneer (Frame + Lath)	Sets default box coverage, weight, and whether lath is computed at all
Outside Corners	4	Drives corner linear footage and the flat panel deduction
Waste Allowance	10%	Added to net area, flat panel, corner footage, mortar, lath, and weep screed

Step 1 — Net Area & Corner Footage

Calculation	Formula / Substitution	Result
Gross area minus every window/door (full deduction)	270 sq ft - 44 sq ft	226 sq ft net area
Waste-adjusted net area	226 x (1 + 10/100)	248 sq ft
Corner linear footage	4 corners x 9 ft	36 linear ft

Step 2 — Flat Panel & Corner Boxes

Calculation	Formula / Substitution	Result
Deducted flat sq ft (corner units replace this strip)	36 ft x 0.75	27 sq ft
Flat panel boxes	CEIL(218.5 / 7.3)	30 box(es)
Corner unit boxes	CEIL(39.6 / 5.5)	8 box(es)

Step 3 — Mortar, Grout & Lath

Calculation	Formula / Substitution	Result
Scratch coat bags	CEIL(248 / 11)	15 bag(s)
Setting mortar bags	CEIL(248 / 15)	17 bag(s)
Grout bags	CEIL(248 / 40)	7 bag(s)
Lath sheets	CEIL(226 x 1.06 x 1.1 / 18)	15 sheet(s)

Therefore, for this job you need 30 flat panel box(es), 8 corner unit box(es), 17 setting mortar bag(s), 15 lath sheet(s), and 7 grout bag(s).

How to Use the Brick/Stone Veneer Calculator

Enter the overall wall height and your building's outside corner count.
Add one wall section per elevation with its width, height, and any window/door counts and average sizes.
Choose the veneer type (Thin Brick or Manufactured Stone) and the substrate type (Frame + Lath or Direct-to-Masonry).
Choose the joint style (grouted or dry-stack), and adjust the advanced product figures if your chosen product's own data sheet differs from the defaults.
Set a waste allowance, then add optional cost inputs for a full material + labor estimate.

Practical Brick/Stone Veneer Tips

Set corner units first at every outside corner, then cut flat units in against them — never the reverse.
Dry-lay a few boxes on the ground first to blend color and texture across boxes before setting anything permanently.
Confirm your setting mortar achieves 100% coverage behind each unit — spot, perimeter, or donut mortaring methods do not meet manufacturer installation guides and risk water intrusion.
Never let veneer extend below the weep screed, and keep at least 4 in of clearance above grade (2 in above hardscape).
Order 5-10% extra from the SAME production run/lot if color-matching a future repair is a concern — batch-to-batch color can vary.
Check the specific product's own installation guide for its exact corner deduction factor before finalizing a flat panel order.

Common Mistakes

Ordering flat panel for the full wall area without subtracting the corner deduction, over-ordering flat boxes.
Skipping a weep screed, or installing it below the required grade clearance, trapping moisture behind the veneer.
Using a spot, perimeter, or donut mortaring method instead of full, void-free setting mortar coverage behind every unit.
Confusing this adhered/thin veneer system with full anchored brick veneer, which needs ties, an air gap, and flashing this calculator does not estimate.
Choosing a generic corner deduction factor instead of checking the specific product's own installation guide.
Not checking the entered unit weight against the 15 lb/sq ft lightweight threshold before assuming no structural review is needed.

Brick/Stone Veneer Calculator Limitations

This calculator covers adhered/thin veneer only — it does not cover full-thickness anchored clay brick veneer (ties, air gap, flashing, weep holes), which is a structurally different masonry-veneer assembly.
This calculator provides estimation only and does not replace a manufacturer's installation guide, ASTM C1780/the MVMA Installation Guide, or a site-specific survey.
The corner deduction factor (default 0.75 sq ft per linear ft) is a commonly cited figure that genuinely varies by manufacturer (0.5-0.75 cited across sources) — always confirm against your chosen product before ordering.
Installed weight includes the veneer UNITS only, not the setting mortar or scratch coat, since no reliably sourced weight figure for those at this calculator's modeled thickness was available — treat the reported weight as a lower bound, not the full assembly weight.
The 15 lb/sq ft lightweight threshold is a planning flag, not a structural or code determination — a wall's actual total weight and any engineering requirement should be confirmed with a design professional.
Every window and door is fully deducted from the net area, since adhered veneer units have no reusable offcuts.
Lath fasteners are counted from each wall's own gross width/height grid, ignoring exact opening cutouts — a disclosed planning approximation, not a substitute for an actual framing layout.
Each wall section is modeled as a rectangle. A triangular gable end should be entered with an average height approximation, or measured separately.
Lath sheet and accessory stock sizes are disclosed assumptions (27x96 in lath, 10 ft weep screed stock) — confirm your actual supplier SKU before ordering.
This calculator does not compute control/expansion joints, flashing takeoff, or a weather-resistive barrier quantity — see this site's House Wrap Calculator for that.
This calculator estimates material quantity and cost only, not structural wall design or an engineered seismic weight review.
Final mortar type, lath weight/gauge, fastener spacing, and weep screed/flashing details should follow the local building code and the specific product's installation guide.

FAQ

Only adhered/thin veneer: Thin Brick Veneer (clay units about 3/8-1 in thick) and Manufactured Stone Veneer (lightweight concrete), both installed the same way — over a scratch coat and lath on a frame wall, or bonded directly to masonry/concrete. It does NOT cover full-thickness ANCHORED clay brick veneer (4 in nominal units with corrugated metal ties into the studs, a 1 in air gap, flashing, and weep holes) — that is a structurally different, far heavier masonry-veneer assembly with its own ties/air-gap/flashing takeoff. If that is what you need, use this site's Brick (Masonry Wall) Calculator instead, which covers full brick wall construction.

Corner units physically replace the flat panel that would otherwise cover that strip of wall — a corner piece has a long leg and a short leg that together wrap both faces of the corner, so ordering flat panel for that same strip would double-order material. This calculator subtracts (outside corner linear footage x a deduction factor) from the net wall area before computing the flat panel order. The deduction factor itself is genuinely manufacturer-dependent: Stoneyard and Petracraft both cite about 0.75 sq ft removed per linear ft of corner, while Eldorado Stone's own guidance works out to about 0.5 sq ft per linear ft. This calculator defaults to 0.75 but exposes it as an editable advanced input — always confirm the exact figure against your chosen product's own installation guide before ordering.

Those materials are all consumed across the ENTIRE net wall area regardless of whether a given square foot ends up under flat panel or a corner unit — the lath and scratch coat go under both, and setting mortar bonds every unit, flat or corner, to the wall. Only the FLAT PANEL box count is reduced by the corner deduction, since corner units are a different, separately-boxed product that replaces flat panel on that strip. Changing the deduction factor shifts how much of the (fixed) net area is covered by flat boxes versus corner boxes — it does not change the total area needing lath, scratch coat, setting mortar, grout, or a weep screed.

Most adhered manufactured stone and thin brick veneer products are evaluated and sold at or under about 15 lb/sq ft (saturated installed weight) — a figure commonly cited across manufacturer ICC-ES evaluation reports. This matters because many jurisdictions require an engineered wall-design check once the SUPPORTING WALL's total weight — including the veneer, its setting bed, and any scratch coat — exceeds the limits in IRC Section R301.2.2.2 (especially in seismic design categories). This calculator flags when your entered unit weight exceeds that commonly cited 15 lb/sq ft ceiling as a planning note only, not a structural determination — a wall's actual total weight and any engineering requirement should be confirmed with a design professional, especially for anything exceeding one story or in a higher seismic zone.

Frame + Lath applies when the veneer is going over a wood- or steel-stud wall with sheathing — it needs a weather-resistive barrier, metal lath keyed with a scratch coat, lath fasteners, and a weep screed at the base for drainage. Direct-to-Masonry/Concrete applies when the substrate itself (CMU block, poured concrete, existing masonry) is already a solid, sound surface the veneer can bond straight to with setting mortar — no lath, scratch coat, fasteners, or weep screed are needed at all, and this calculator zeroes those quantities out entirely rather than showing a misleadingly small nonzero number.

Grouted joints are the traditional look with visible mortar lines between units, finished by packing grout into the joint after setting — this calculator estimates a grout bag quantity from your net wall area for that style. Dry-stack/tight-fit joints butt units directly against each other with little or no visible joint and no grout packed in afterward, common with many manufactured stone profiles — selecting this style zeroes the grout quantity out completely, not just to a small nonzero number.

Flat veneer units are simply field-cut and butted through an inside corner with no dedicated accessory the way an OUTSIDE corner needs a wrap-around corner unit — an outside corner is the vulnerable, exposed edge that needs a clean factory-formed piece, while an inside corner is just two flat courses meeting at an angle. This is the same simplification this category's Stucco Calculator makes for its own corner bead, and Fiber Cement/Wood Siding make for their corner boards.

A weep screed sits at the base of a Frame + Lath wall and gives any moisture that gets behind the lath/scratch-coat assembly a path to drain out rather than wicking into the framing — it's the same drainage accessory this category's Stucco and House Wrap calculators rely on for their own frame systems. It commonly needs to sit at least 4 in above grade (2 in above any hardscape), with veneer never extending below it, so that drainage path never gets buried or blocked. A masonry/concrete substrate has no such cavity behind the veneer to drain, so Direct-to-Masonry needs no weep screed at all.

10% (the default here) covers a typical job with straightforward rectangular walls and a normal number of openings — use 5% for a simple, low-cut job, and 15% for a complex job with many openings or extensive field-cutting. The allowance applies to net area, the flat panel order, corner linear footage, scratch coat, setting mortar, grout, lath, and weep screed — all scale with the same waste-adjusted area or length.

The cost estimate is only as accurate as the per-box and per-bag prices you enter — this calculator does not look up regional pricing. Enter your own supplier's quoted prices in the currency you select, and treat the total as a planning estimate to compare scenarios, not a quote.
