Brick Slips Calculator
This brick slips calculator is designed for customers planning a fireplace, feature wall, kitchen brick tile splashback, exterior brick cladding project or commercial interior. Choose the exact brick slip product you want, add your wall measurements and the calculator will estimate full boxes, external corner slips and the key installation accessories needed for the job.

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 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. Measuring accurately before ordering helps reduce waste, avoid under-ordering and choose the right amount of adhesive, mortar, primer and spacers.
The calculator uses a 0.5m² box guide for flat brick slips, adds optional 10% wastage and calculates external corner slips separately at 14 corner 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. Select the exact brick slip product first, then enter your wall height and width in metres. The calculator estimates the flat wall area, applies optional wastage and converts the total into box quantities based on the coverage used on your brick slip product pages.
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 and corner slips are not normally needed. This helps customers understand the difference between a visible external return and an internal corner before ordering.
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 makes the page useful for 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. For a complete fitting list, visit brick slip installation accessories.
After calculating, customers can continue to the main UK brick slips collection to compare rustic red brick slips, reclaimed style brick slips, grey brick slips, white brick slips, London yellow brick slips and other brick tile finishes. They can also read the brick slips installation guide, check the brick slips FAQ page or browse the Brick-Slips.UK blog for more project advice. These links help customers move between measuring, learning and buying without leaving the correct brick slips section of the website.

Calculator FAQs
How does this calculator work?
It multiplies your wall height by width, optionally adds 10% wastage, divides by the product 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 a practical guide based on stated coverage. Actual use can vary depending on wall condition, joint size and fitting method.
Need help?
Unsure how to measure or whether your project needs corners? Send your measurements or project photos before ordering.
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.
Examples of external corners: chimney breast front edges, outside house corners, porch returns, pillars and window reveals. Examples of internal corners: the inside corners of a fireplace recess or alcove.
