Brick walls add charm and privacy to your yard. Using brick to build a garden wall is more complicated than just slapping some mortar and brick together. You will need to design, budget and plan the wall well before you begin building. One of the most important aspects of planning the design of a brick fence is understanding how much the wall is going to cost and how much brick to buy.

Draw a detailed sketch of your fence. You will need to plant the height and width of the fence as well as any decorative elements like columns. Brick walls higher than 3 feet need to have piers every 6 feet. Piers are support columns keeping the wall upright and sturdy.

Calculate the square footage of the fence. This calculation is determined by multiplying the length of each section of the fence by its width. Do not include the piers in this calculation.

Add in additional square footage for each pier. Calculate the square footage of each pier by multiplying the length by the width and height of the column.

Add the square footage of the sections to the square footage of the piers. This is your total square footage.

Multiply the total square footage by five. The typical brick is 4 inches wide and 8 inches long. It takes five bricks to create 1 square foot of wall. The total number will be the minimum number of bricks needed to build your brick fence.

Increase the total number of bricks needed by 5 per cent. Extra brick will allow for broken bricks and scrap from cuts. Multiply the total number of bricks found in step 5 by 1.05 to get the total bricks.

Calculate the cost of the brick. Visit your local paving store or home improvement centre to determine the cost of each brick. Ask the salesperson about any volume based discounts you might be eligible for. Multiply the total number of bricks by the price per brick. Add any taxes or service fees to the total.

#### Tip

If you are planning a double thick brick wall with two layers of brick, you will need to double the calculation for the fence segments found in step 2. Piers will be the same measurement regardless of the thickness of the wall.
