Building a garden wall requires accurate brick and mortar quantities to avoid costly over-ordering - yet it is one of the easiest jobs to get wrong at the materials stage. A single-skin wall uses roughly 60 bricks per square metre of face area, while a double-skin wall doubles that. Mortar mix ratios, joint thickness and waste all affect the final figure, which is why a dedicated brick calculator gives far more reliable results than a rough rule of thumb.

Getting the foundation concrete volume right is equally important. A strip foundation that is too shallow or too narrow will crack and shift over time, while over-ordering ready-mix concrete is an expensive mistake. This kit covers every material stage from foundation trench through to the finished brickwork - enter your wall dimensions once and each calculator opens pre-loaded with the relevant inputs. Work through each step at your own pace and save each result directly to your project.

What this kit covers

Work through these 4 calculators in order. Each one uses your wall dimensions to pre-fill the key inputs - just refine the details and save each result to your project.

1
Brick Calculator
Calculate the number of bricks needed for your garden wall. Choose between single-skin (102mm) or double-skin (215mm) construction and the calculator works out quantities with waste.

2
Masonry Mortar
Work out the sand and cement quantities (or pre-mixed mortar bags) needed for laying the brickwork.
Open calculator
3
Concrete Volume (foundations)
Calculate the concrete needed for the strip foundation. Enter the trench dimensions - typically the wall width plus 150mm either side and 300-450mm deep.

4
Aggregate & Ballast
Work out hardcore or ballast quantities for the foundation trench fill or sub-base.
