Fencing Blocks: Tips To Calculate

What are the tips to calculate the number of fencing blocks required for a building?

A fence is a building that surrounds a space that is normally outdoors, such as a field, a yard, etc. It is usually made of wood, wire, and blocks, although it can take other shapes as well. On the other hand, the computation of the materials required to construct a block fence is the topic of this article.

This article serves as guidance on how to determine how many fencing blocks you will need to build a fence. Our calculation is based on a 9-inch block fence and uses a model plot of land that is 120 feet by 60 feet for fencing purposes.

We are measuring a fence that is approximately 120 feet long from the dimensions of our model land, and since there are two lengths, we will multiply by two to get a total of 240 feet. (120 x 2) = 240

For our 60-foot breadth, the same procedure would be followed. This is because 60 x 2 = 120 feet, or two breadths, are present.
In order to get a 360-foot perimeter line fencing, we would then add the two lengths (240 + 120) together.

The next step is to convert 360 feet to inches. A foot is 12 inches long, therefore we multiply 12 by 360 feet to get the total number of inches, or 4320.

We must divide 4320 by 18 inches to obtain the line numbers for the blocks that will form the fence’s 4320-inch perimeters. This is due to the fact that all blocks, whether they are 6 inches or 9 inches in length, are 18 inches long. There are roughly 240 lines of blocks when 4320 inches are split by 18 inches.

The entire line of blocks will then be multiplied by the number of coaches of blocks you desire based on your height. Assuming you are 7 feet tall, this translates to 9 coaches, which equals 240, which is then multiplied by 9 to become 2160 blocks.

For our example, land fencing is all you need. But always keep in mind to purchase an extra 10% of blocks in case of any break.

Approximately 70 standard blocks should be covered by a bag of cement, speaking of that material. Our model fence will therefore require roughly 34 bags of cement in total.

Because they are necessary, pillars must be taken into account when constructing a fence. In this scenario, there would be 40 pillars, with each pillar being 6 blocks away from the one before it (240 divided by 6). For those 40 pillars, about 17 sacks of cement would be required.

About 15 sacks of cement would be required for the floor binding of the fence. It would take around 66 bags of cement in total to complete the project.

Additionally, the gate and the pillars that are taking up space in the fence need to be removed. Our model gate is 12 feet in length; if the gate columns or pillars are 14 inches each and there are two of them holding the gate, that is 28 inches or 2; 4 feet plus 12 feet = 14.4 feet; roughly 15 feet.

In light of this, each pillar or column made of 9 inches of concrete is 9 inches square, which we will multiply by the previously mentioned 40 pillars. 30 feet plus 15 feet is 45 feet, thus 9 x 40 = 360 inches, or (30 feet + 15 feet = 45 feet) / 18 inches = 30 blocks multiplied by the number of coaches, or 30 x 9 = 270 blocks less 2160 blocks, or 1890 blocks altogether.

Materials Used for Fencing Blocks

Asides from block and cement, here are some other materials to be used;

  • 40 lengths of 12mm iron rod since one pillar is equivalent to 1 length.
  • 3 lengths of 16mm iron rod for the 2 big pillars for holding the gate.
  • 90 planks of softwood for the framing of the fence
  • 1 truck of granite to be used for the wall foundation
  • 4 trucks of sharp sand
