Calculate stone cladding, stone slips, corners and accessories in one place.
This dedicated stone cladding calculator helps customers measure a wall, choose a product from the stone cladding collection and build a complete order with boxes, corner packs and installation accessories. It is useful for anyone planning stone cladding, stone slips, stone wall cladding, fireplace stone cladding, chimney breast cladding, media wall stone cladding, internal feature walls or selected exterior stone cladding projects.
The calculator uses a 0.8m² box guide for flat stone cladding, adds optional 10% wastage and calculates external stone corner packs separately using a 1 pack per linear metre guide. After checking the quantity, customers can continue to the main shop all stone cladding page, add stone cladding accessories, or read the how to install stone slips guide.
What counts as an external corner?
An external corner is a corner that points outwards, such as the front edges of a chimney breast, the corner of a house, a pillar, a return edge or a window reveal. Internal corners, such as the inside back corners of a fireplace recess, normally use straight stone slips cut to fit.

Stone cladding calculator buying guide
Use this stone cladding calculator when working out how much stone cladding you need for a fireplace, chimney breast, feature wall, kitchen wall, media wall, hallway, garden room, porch return or selected exterior wall. Stone cladding is also searched for as stone slips, stone wall cladding, stone veneer, pre-cast stone cladding, stone cladding panels and faux stone cladding.
For fireplace stone cladding and chimney breast projects, measure the main front wall separately from any returns. If the edge turns outwards and remains visible, enter the height of the external corner so the calculator can estimate stone corner packs. For internal fireplace recesses, straight stone pieces are usually cut to fit.
Accessories are included because a stone cladding order is rarely just the stone itself. Adhesive and mortar are estimated at approximately 3-5m² per bag, primer is estimated up to 7m² and fire cement is optional for suitable hot areas only. This supports searches such as how much adhesive for stone cladding, stone cladding mortar coverage, stone cladding per m2 and stone cladding corner calculator.
After calculating, customers can continue to the main UK stone cladding collection, read the stone cladding installation guide, check the stone cladding FAQ page or browse the Brick-Slips.UK blog for more project advice.

Calculator FAQs
How does this calculator work?
It multiplies your wall height by width, optionally adds 10% wastage, divides by 0.8m² box coverage and separately calculates external corner packs.
Do I need external corners?
Only use external corners for outward-facing returns such as chimney breast edges, house corners, pillars and window reveals.
Are accessory quantities exact?
They are practical buying estimates based on stated coverage. Actual use can vary depending on wall condition, joint size and fitting method.
External corners explained
External corners point outwards. Use corner pieces where the finish wraps around a visible outside edge. Internal corners point inwards and are usually completed by cutting straight slips to fit.
Count these: chimney breast front edges, outside house corners, porch returns, pillars and window reveals. Do not count these: inside fireplace recess corners or alcove back corners.
