When we talk about Fencing projects, I know someone would want to wonder why fencing is very important to us. Well, fence is very important as it helps secure your plot of land from encroachment. Now I am going to write on how you could easily calculate the number of Blocks Required to Fence a Plot Of land with ease.
Do not forget that I have an article describing how to calculate fencing Project but on that post, I chose to use a plot measuring 100ft by 60ft as a case study.
On this current post, I’ll be using a plot measuring 100ft by 50ft but then, it’s all the same procedure except you’ve never been a fervent reader here.
So how do we calculate the number of blocks required to fence one plot of land?
From this Post, You will get to know:
The number of bags of cement needed for this project,
Amount of sharp sand that will be required as well as the
Number of trips of granite you’ll need
The simplest way to calculate the numbers of blocks you need for your fence project, assuming you are fencing a land measuring 100 feet by 50 ft, a standard plot
This calculation is based on 6 inches block fence and by the time I’m done, you’ll only need to ask your engineer when he’s commencing work on your site.
How To Calculate The Number Of Blocks To Fence One Plot Of Land
Before we start, lets understand The measurement we are using is 100 ft (length) and since we have two lengths that is multiply by 2 which is 200 ft. (10 x 2) = 200
The breadth is 50 ft and also since we have 2 breadths that equal 100 ft (50 x 2) = 100
Then (200 + 100) that is 300 feet perimeter line fencing.
The calculation For Number a of Blocks Goes Thus
(we are to convert this 300 feet to inches ) since a foot is 12 inches , now let us multiply 12 inches by 300 ft which is 3600 inches.
Now to get the line numbers of blocks that will go around the fence perimeters of 3600 inches or 300 feet, we would need to divide 3600 by 18 inches, since the length of any block be it 6 inches or 9 inches is 18 inches.
Now 3600 inches divided by 18 inches is approximately 200 line of blocks , then we must multiply that by the numbers of coaches of blocks you want for your height, assuming 7 ft which is 9 coaches that means 200 multiplied by 9 which is 1800 blocks and that is all you need anything aside from this is fake and fraud.
Note: Its always recommended that you make an allowance by adding 10% of the total number of blocks to cater for breakages but you can still decide to work with just 1800 since I know we didn’t leave space for joints.
Now let’s consider other things
Now that we’ve known the number of blocks required to fence a plot of land, the next question would focus on ascertaining the number of bags of cement that would enable us bond the 1800 blocks calculated above.
HOW MANY BAGS OF CEMENT WOULD BE REQUIRED TO BOND THE 1800 BLOCKS?
In our normal English we call the act of bonding Setting of block
By standard, it is required that a bag of cement be used for 70 blocks (it could be lower if you’re using hollow blocks)
Therefore, for 1800 blocks, you’ll need 1800/70 = 25.71 bags of cement or approximately 26 bags of cement.
Note: This highly depends on the mix ratio used for mortar. Mix ratio could differ, it all depends on the engineer on site.
As For the number of Trips Of granite you’ll need, it all depends on what your pocket can carry.
While I recommend that granite be incorporated into the foundation concrete, it’s not compulsory that it be used. This of course depends on where you are, for a plot of land situated in a highly swampy area, casting is very compulsory, it may even be decided that reinforced concrete be used before introducing blocks.
Well, I hope I’ve been able to describe in details how to easily calculate the number of blocks required to fence your plot of land in Nigeria, especially for a 100 by 50ft plot.

Quickly this site will indisputably be famous among all blogging people, because of its fastidious articles or reviews.
Thanks for saying so dear. It means a lot to me
Wow this is beautiful.
More Grace to you
Dear Sir, what if the land is dry one, does iron rod needed for pillar fencing again? And how many trip of granite needed likewise.
Can you give us the cost price of all these items please. Thanks
You're welcome sir
Please use any of the contact details on the "Contact Page" to send the dkmensions of the piece of land under consideration
Hello, thanks for this valuable information. Is the number of blocks for pillars included in the 2119 please? Thank you.
Nope. This is for a flat wall only.
Awesome.
Thanks for the clear explanation
Please Sir can you calculate for me the amount of blocks and cement needed to fence 70/100 plot of land (8 feet high) which has 3 bedrooms built on the land.
Hopefully it would be the same number of blocks if it was a 10 bedroom house or just 1 bedroom mansion…as long as the plot was only 70 X 100 at 8ft. High…
Very helpful.Thanks a million
Great piece. I find this very useful as it will sure help my planning. Thanks Mr. Nwachukwu.
I'm glad you found it useful sir.
Wow! Thumbs up guys. This is so comprehensive. Thanks so much for this article. This blog is dope.
Enter your comment…sir concerning 1acre of land, sir how many 6inch block will b needed to fence it up to 12coach
Nice one sir, very useful…but what of the blinding for the foundation of the fence?
If the 1 acre of land is 200 x 200 ft, then I'll need to work extra to get the number of blovks required
So confirm the dimension
At each corner, does it also requires a concrete with iron rods and d middle
Greetings. My Engr. I have a land measuring 200feet x 200feet to fence. With d calculation pattern u stated above,I have used it to get d total of blocks I needed, which is 2500 blocks and 40 bags of cement for bonding d blocks together. The ideal coaches or level is 4 coaches or levels. My question is, does it require a reinforced concrete plant at d middle of the line of each side of the land?
@Seysony
The use of Reinforced concrete on fence projects depends on a few factors
1. Location of Fence with reference to the road. If the fence is very close to a busy road, specially that plied by heavy duty trucks/Heavy vehicular traffic, then its highly recommended that you put a column at every 6th block
2. The nature of the soil: If the site is located on a plot with weak soil/peat or swampy area, you can use Columns also
3. Size of the Plot: This is where I think you need most. You mentioned 200 x 200. So if you're fencing this, I think you'll need to place columns at regular intervals. The gap between each column is something that must be decided by the site engineer considering factors 1 & 2 above.
However, if you have money, you can also use columns wherever you want it
Enjoy
Great job thanks for that.
Great, thanks engr it really means a lot to me.
Now I can estimate how much it will cost me to make a fence in my land
Thanks for the great work done. Please may I know the trip of sand that will be needed for the block sitting for 1575 blocks
Thanks for your detailed blogging. God bless you sir.
You are very much welcome dear
Thanks for your help. This is good and helping.
You're welcome sir. Thanks for finding time to read through

Thank you.
Nice write up. I enjoyed reading your article. Thanks and keep it up.
Please quickly reach me on +2347035528329
Interesting
Hello there, great job with your calculations . It is very helpful. However, i wish to point out a fundamental point of note in your calculation. Your calculation was for a flat fence that had all for sides sealed. if you make a provision for a gate, then the width won't be 50×2 because the gate will take up a large chunk of the front wall. Great article sir.
Thanks for your enlightenment, it helped a lot
Thank you so much…I've gained a lot..
I am glad it helped you sir
Cost of rods and qty of sand for mortal for a plot of land
It's not every fence that requires rod.
As for sand and mortar, check other posts under Fencing topic.
This is very informative
@seysony that's a long length and I will advice you introduce pillars maybe at each 10 blocks space
Introducing a pillar at 10 block span will leave a weak wall. Make a pillar every 6 blocks especially if the said plot is located close to a road way!
6 blocks will be strong but also ensure you consider the nature of the soil as some soil would require reinforcements due to weak or poor bearing capacity
Awesome
How many blocks is required to complete a fence of 11coaches of 6plot of land including coloums and bags of cement
I APPRECIATE YOUR INFORMATION,BUT YOU SHOULD HAVE SPECIFY TO PEOPLE THAT ARE NOT IN THIS FILED THAT THERE WILL BE A MIDDLE REINFORCEMENT OR BLOCK PILLARS TO PARTITION THE FENCE WALL WHICH I BELIEVE WILL ADD MORE NUMBER OF BLOCKS OR CEMENT REQUIRED. ALSO THE FENCE NEED TO BE CHAIN IN ORDER TO AVOID CRACK THAT WILL DEVELOP WHEN THE SOIL SETTLE.
So i can make it
I was wowed reading this masterpiece. I got all the information I needed on this article.
May God almighty replenish ur knowledge. I gained a lot here. Thank you Sir.
And bless you too for dropping by
Good PM bro, pls can I get the estimate of fencing a 120 by 50 plot of land I try getting what it will cost me but can't figure it out. And the cost my engineer gave me is outrageous. Thanks
Your information is very useful. God bless you.
You're very welcome sir
You can easily reach me with the contact details on contact us page.
Once you contact me, I'll give an estimate depending on the number of coaches you want your wall to be
Thanks so much. I find this article timely, helpful and informative.
Thanks for your generosity. Your piece is most helpful. May God reward you.
Good day Mr Richard, pls how can you calculate the number of blocks for a fencing that have block pillars? How can you calculate the number of blocks in each block pillars? Thanks

Quickly see the post here https://guardianconstructors.com/2019/12/what-is-cost-of-fencing-plot-of-land.html?m=1
Good sir well done for that great calculation you made
But then I do oberserve that when u are doing your convertion from feet (ft) in to inches you used 12 , but. I think it should be 25.4 which will give on inches not 12
Good
So grateful for this. Thumbs up
Thank you so much I really appreciate your time to explain all this in detail it's going to help alot.
Very helpful information
Great information very accurate and precise
That's a very good idea
From Ghana. I appreciate this..
I am walling my one hector plot. Great tip
Thanks for that information sir
Sir. I used the calculations methond mentioned above to calculate for 132 ft by 82.5 and I got 4290 blocks and 61 bags of cement, but I am finding it difficult to calacut the cement and crush stones.
Crush stones for foundation you mean? If yes, there is another content for that, respond let me link you to it sir
