Fence Calculator

Planning to build a fence around your property in Nigeria? Our free fence calculator helps you determine exactly how many blocks you’ll need before you start your fencing project. No more guesswork, no more overspending on materials you don’t need.

How Our Fence Block Calculator Works

Simply enter your land dimensions, specify the height you want (measured in coaches), and indicate whether you're planning to include a gate. In seconds, you'll get an accurate estimate of the total blocks required for your fencing project.

What You'll Need:

• Length and breadth of your land (in feet)
• Desired fence height (number of coaches)
• Whether you're including a gate

Of course! Here's that text rewritten in a more fluent, conversational, and easy-to-follow tone.

Calculation

To find out how many blocks you need is simpler than it seems. We break it down step-by-step. Let's walk through a standard calculation for a plot of land, assuming there's no gate for now (we'll add that in later).

Here's the basic process:

1. Find the Perimeter: First, we calculate the total area of your land.
   • Formula: Perimeter = 2 × (Length + Breadth)
   • This gives us the total linear feet you need to fence.
2. Convert to Inches: Since block sizes are usually given in inches, we convert the perimeter.To convert to inches we use the standard unit : 1 feet = 12 inches
   • Conversion: Total Inches = Perimeter (in feet) × 12
3. Calculate the Blocks for One Row: Now, we find out how many blocks are needed for a single row (or "coach") around the perimeter.
   • Formula: Blocks per Coach = Total Inches ÷ 18 (since a standard block is often 18 inches long).
4. Decide on the Fence Height: The final step is to determine how tall you want your fence. A common and secure height is 7 feet, which typically requires about 9 rows of blocks.
   • Formula: Total Blocks = Blocks per Coach × Number of Coaches

What about a gate?

That's easy! If you're including a standard 12-foot-wide gate, we simply subtract that space from the initial perimeter before we start our calculations.

• Formula with Gate: Perimeter = [2 × (Length + Breadth)] - 12

What if I don't know my land size in feet?

No problem at all! This is a very common situation. To help you get started, you can use the standard plot sizes in the table below as a guide.

Land Size	Measurement (Ft)
1 plot	50 x 100 or 60 x 120
1/2 plot	25 x 50 or 30 x 60
1 Acre	66 x 660
1 Hectare	328 x 328
