One aspect of brickwork which often causes confusion is estimating how numerous bricks or blocks will certainly be required for a planned wall - you don"t desire to run out before you finish but you also don"t want a pallet load of material left unused once you have actually finished. Do these approximates is reasonably straight forward using simply a few figures.

First the variety of bricks/blocks because that the total wall is calculated, climate the additional number of bricks for any piers. This are included together and also then a 10% allowance must be added for wastage and also breakages - the figures listed below do not encompass this allowance.

## Calculating the variety of bricks

Standard, UK, metric bricks are approximately 215 x 102.5 x 65mm, the mortar joints used are normally about 10mm both horizontally and also vertically.

### Half brick wall

A fifty percent brick wide wall surface requires 60 bricks per square metre.

So the first stage is simply to measure up the height and length (including any kind of piers) of the wall in metres, multiply them together to give the area in square metres, and also then main point this through 60.

So the total number of bricks for the wall is:

wall height (metres) x wall length (metres) x 60 = number of bricks

### One brick wall

A one brick wide wall requires 120 bricks every square metre.

So the first stage is just to measure the height and also length of the wall surface in metres, main point them together to provide the area in square metres, and also then main point this by 120.

So the total variety of bricks because that the wall surface is:

wall height (metres) x wall surface length (metres) x 120 = number of bricks

### Single brick piers in half brick walls

Where single brick piers are developed into a half brick wall, each pier requires second 14 bricks every vertical metre.

So the total number of bricks because that the piers is:

number that piers x wall surface height (metres) x 14 = number of bricks

### One and also a fifty percent brick piers in a fifty percent brick wall

Where one and a half brick piers are developed into a half brick wall, every pier requires an additional 34 bricks every vertical metre

So the total variety of bricks because that the piers is:

number the piers x wall surface height (metres) x 34 = variety of bricks

## Calculating the variety of blocks

Standard, UK, metric blocks are around 450 x 215 x 100mm (some space thicker however this will not effect the variety of blocks required per square metre that wall), the mortar joints offered are normally about 10mm both horizontally and also vertically.
