Calculating the Number of Bricks - Guideline:


One aspect of brickwork which often causes confusion is estimating how many bricks or blocks will be required for a planned wall - you don't want to run out before you finish but you also don't want a pallet load of material left unused when you have finished. Making these estimates is fairly straight forward using just a few figures.

First the number of bricks/blocks for the total wall is calculated, then the additional number of bricks for any piers. These are added together and then a 10% allowance should be added for wastage and breakages - the figures below do not include this allowance.

Single Brick Wall

A single brick wide wall requires 52 standard bricks per square metre. (see above diagram)
So the first stage is just to measure the height and length (including any piers) of the wall in metres, multiply them together to give the area in square metres, and then multiply this by 52.

So the total number of bricks for the wall is:
wall height (metres) x wall length (metres) x 52 = number of bricks

Double Brick Wall

A double brick wide wall requires 104 bricks per square metre.
So the first stage is just to measure the height and length (including any piers) of the wall in metres, multiply them together to give the area in square metres, and then multiply this by 104.

So the total number of bricks for the wall is:
wall height (metres) x wall length (metres) x 104 = number of bricks

 

Single Brick Piers

Where single brick piers are built into a single brick wall, each pier requires an additional 12 bricks per vertical metre.

So the total number of bricks for the piers is:
number of piers x wall height (metres) x 14 = number of bricks

 

 

One and a Half Brick Piers


Where one and a half brick piers are built into a single brick wall, each pier requires an additional 29 bricks per vertical metre.

So the total number of bricks for the piers is:
number of piers x wall height (metres) x 29 = number of bricks

 

Please note that this is a guideline only and should be used as such.

For all other brick types adjust accordingly.
