A 12 ft × 8 ft wall in Stacked Stone interlock needs 16 panels, about $1,599 in panels. Use the coverage printed on your product page, never the nominal 2 × 4 size: these panels are 24 × 48 in overall but cover between 6.70 and 7.80 sq ft depending on the design, and on this wall that spread is the difference between 14 panels and 16.
Panels are cut to fit, so this one works in area. List each wall separately if you have more than one.

Every coverage figure on this page comes from Texture Plus, because those are the panels we actually install. They design, tool and manufacture their own product in a 25,000 square foot plant in Lincolnton, North Carolina, having moved the operation there from New York in 2018. Their catalogue runs to more than a thousand designs across brick, stone, wood, concrete, slate, tile, bamboo and metal. Panels are 2 × 4 ft nominal and start at $99.95 each in the 1 to 24 tier.
We specify them for reasons that only show up once you are on a job. The range is wide enough that a whole house can come out of one catalogue, which matters more than it sounds when a client picks a look. Quality has been consistent. The panels weigh roughly five to six pounds, so one person can hold one against the wall while the other checks the line, and that single fact changes how fast a job goes. Their samples are actual product rather than a printed swatch, so what a client approves is what turns up. Quotes have matched invoices, which for a made-to-order product is not a given.
The longer version, including the places these panels do not work, is in what we have learned installing faux panels. Their own installation guide and FAQ are worth reading before you order.
Faux panels are sold as 2 × 4 foot, and category pages say "24″ x 48″ overall size. Coverage varies." That last phrase is doing a lot of work. On a standard panel the coverage dimensions match the overall dimensions, so Historic Brick measures 47½ × 23½ in and covers all 7.80 sq ft of it. On an interlock panel the edges overlap to hide the seam, so a Stacked Stone panel is 47 in long but only covers 41½ in of wall — 6.70 sq ft.
That is a 14% spread between the highest and lowest coverage in the range. Any calculator that assumes one number for every design has to be wrong for most of them, and the manufacturer's own tool says as much: it asks only whether your panel is standard or interlock, and carries the disclaimer that "as our panels vary in size and design, our calculator is an approximation." Ours asks for the figure printed on your product page instead. It takes five seconds and it is the difference between one delivery and two.
Lead time is 10 to 20 business days, custom and special orders are non-returnable, and a cancellation once an order is in production carries a fee. Returns on stock items run to 15 days with an RMA, the original box, buyer-paid return shipping and in some cases a 25% restocking charge. None of that is unusual for a made-to-order product, but it does mean a short order is expensive in time rather than money. Count the corners and the adhesive before you press the button, not after.
Texture Plus is explicit that panels go up with construction adhesive and screws, and that both belong in every joint. Joints are butted on straight runs and mitred at corners, then every joint and screw hole is filled with colour-matched caulk. Budget one tube per five panels, one per ten corners and one per ten ledgers, which is what this calculator does.
The fire-rated version carries an ASTM E84 Class A rating and costs $13.25 more per panel. It is also not waterproof, so unlike the standard panels it cannot go outside. If you are speccing an exterior wall, that upgrade is not available to you.
Work out your wall area, add a waste allowance, then divide by the coverage of the specific design you chose. The critical step is using real coverage rather than the nominal 2 × 4 ft size. Texture Plus panels are 24 × 48 in overall but cover between 6.70 and 7.80 sq ft depending on design, because interlocking panels overlap. On a 96 sq ft wall that spread is the difference between 14 panels and 16.
On a standard panel the coverage dimensions equal the overall dimensions. On an interlock panel the edges overlap to hide the seam, so coverage is smaller than the panel: a Stacked Stone interlock panel measures 47 in long but covers 41½ in of wall. Texture Plus recommends interlock for any run longer than 4 ft, which is where butt seams start to show.
One tube per five panels, one per ten corners and one per ten ledgers, per Texture Plus. Panels are fixed with construction adhesive and screws, not one or the other, and every joint and screw hole is caulked afterwards in a colour-matched caulk.
Standard panels are rated for exterior use, described as weather proof with near zero UV degradation. The exception is the fire-rated version, which Texture Plus states is not waterproof and is interior only. That upgrade also adds $13.25 per panel.
About 5 to 6 lbs a panel. On thickness the manufacturer's own pages disagree: the FAQ says an average of ½ to ¾ in, while several product pages list thicker profiles, up to 1 to 1½ in on Random Rock. Read the product page for the design you are buying rather than the general FAQ.
