Calculate brick slips, brick tiles, corners and accessories in one place.
This dedicated brick slips calculator helps customers measure a wall, choose a product from the brick slips collection and build a complete order with boxes, corner brick slips and installation accessories. It is useful for anyone planning brick slips, brick tiles, brick veneer, brick cladding, fireplace brick slips, kitchen brick tiles, internal brick feature walls or external brick slip projects.
The calculator uses a 0.5m² box guide for flat brick slips, adds optional 10% wastage and calculates external corner brick slips separately at 14 corner brick slips per linear metre. After checking the quantity, customers can continue to the main shop all brick slips page, add brick slip accessories, or read the how to install brick 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 brick slips cut to fit.

Brick slips calculator buying guide
Use this brick slips calculator when working out how many brick slips you need for a feature wall, fireplace, kitchen splashback, bathroom wall, exterior brick cladding project, hallway, bedroom or living room. Brick slips are also searched for as brick tiles, brick slip tiles, brick effect tiles, brick veneer and thin brick cladding, so this page brings the measuring and buying process together in one place.
For fireplace brick slips 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 corner brick slips. For internal fireplace recesses, straight slips are usually cut to fit.
Accessories are included because a brick slip order is rarely just the slips themselves. Adhesive and mortar are estimated at approximately 3-5m² per bag, primer is estimated up to 7m², 10mm spacers are estimated up to 5m² and fire cement is optional for hot areas only. This supports searches such as how much adhesive for brick slips, brick slip mortar coverage, brick slip spacers, brick slips per m2 and brick slips with corners.
After calculating, customers can continue to the main UK brick slips collection, read the brick slips installation guide, check the brick slips 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 0.5m² box coverage and separately calculates external corners.
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.
