Brick & Stone Veneer Calculator
Manufactured stone and thin brick veneer are sold as boxes of flats covering a set area, with corner pieces priced separately by linear foot. This calculator estimates flats only — add corners from your supplier's coverage.
Project type
Wall measurements
Enter each wall's length and height in feet and inches. Wall area = length × height.
Gable ends
No gables added. Gable area = base × rise ÷ 2.
Windows & doors
No openings added. Each opening's area is subtracted from your gross siding area.
Siding material
Waste factor
Waste accounts for cuts at corners and openings, gable angles, damaged pieces, and pattern matching. 10% is a common starting point for a simple rectangular home; complex roof lines or diagonal cuts often need more.
Trim & accessories
Actual accessory requirements vary by installation method and manufacturer — use these as a starting checklist, not a final order.

Contact usHow it's calculated
- 1. Net siding area = gross wall and gable area minus openings.
- 2. Required area = net area plus your waste allowance (15% is a common starting point for veneer).
- 3. Box coverage defaults to 9 sq ft per box of flats — edit this to match your product label.
- 4. Boxes needed = required area ÷ box coverage, rounded up.
Worked example
A home with 1,200 sq ft of net wall area and a 15% waste factor:
| Net area | 1,200 sq ft |
| Plus 15% waste | +180 sq ft |
| Required area | 1,380 sq ft |
| Siding squares | 13.8 squares |
| Boxes to order | 154 boxes |
Outside corner pieces are ordered separately by linear foot and are not included in this box count.
Assumptions
- • Box coverage varies significantly by manufacturer and stone or brick profile — the default is a generic starting point.
- • Corner pieces are priced and ordered separately from field flats; use your supplier’s corner coverage per linear foot.
- • A 15% waste factor is typical for veneer, higher than most siding materials due to cutting and breakage.
Tips
- • Order corner pieces first — running short delays a job more than running short on flats.
- • Buy a few extra boxes from the same production lot; stone and brick color can vary noticeably between lots.

Frequently asked questions
How many boxes of stone veneer do I need?
Divide your required siding area (net area plus waste) by your product’s coverage per box of flats, then round up. This doesn’t include corner pieces, which are ordered separately by linear foot.
What waste factor should I use for brick or stone veneer?
15% is a common starting point; go higher for intricate cutting around openings or a highly textured profile with more breakage.
