How many blocks does it take to build a house? It can take about 9380 blocks to build a 6 bedroom double-story house with third-floor space. The house would be about 4500 sqft. If you plan on building a larger house then the no. of blocks required would increase. Similarly when you build a smaller house the no. of blocks required would suddenly decrease a lot. For e.g. if you build a double story 5 bedroom house on the square footage of about 2250 sqft. then the no. of blocks required would be about 3/4 what the previous estimate was i.e about 6500 to 7000 blocks would be required in total. But if you then go on and build a single-story house in the same square footage then it will be about half of 6500 i.e. about 3250 blocks. So it all depends. You need to calculate the total wall area of your house and then divide it by the area of the block to get the no. of blocks required for the building. The actual formula to calculate the no. of blocks is :

Total wall area of one wall = Length of one wall x Height of one wall

Total wall area of all the walls = Sum of wall areas of all walls

The total area of one block = Length of one block x Height of one block = 16″ x 8″ / 12″= 10.67 ( I have given the size of the standard block here. If you are using different size blocks then you would need to calculate their area by multiplying their length and height. Do not use the depth of the block in this formula as it will give you false results).

Total no. of blocks required = Total area of all walls / Area of one block

Note: This is a rough method used by builders, contractors, and masons. To calculate the exact no. of blocks to the dot you should see this video. It explains the method to calculate the no. of blocks using volume which gives much more accurate results. It also discusses the space used by mortar. It is mostly used by civil engineers and is quite complex, but I have linked it here for completeness.

How many blocks do I need to build a 3 bedroom house?

To build a three-bedroom house you would need about 2650-3250 blocks if you are building a single-story house with a square footage of 2250 sqft. If you plan on building a double-story house then the no. of blocks required would be about 6500. It is very often that people overestimate the no. of blocks required to build their house. This is mostly based on the false assumption, that blocks will break during construction, This is hardly the case. If you build by employing full size and half size blocks, which rarely occurs then you can significantly cut down on the breakage.

How many blocks do I need for a 4 bed house?

For a four-bedroom house, the no. of blocks required would be about 6700. You may think this is the same as the three-bedroom house. Which is very true. The no. of blocks required vary very little if you build an extra room. It takes about 100 extra blocks to build each wall of a room, give or take. If you increase the no. of rooms by one then you would only add 200 blocks to the total no. of blocks required. This is because you would only need to put two internal walls only to wall off space into an extra room.

How many blocks can build a fence 50 by 100?

If the height of a standard fence is about 5 ft. then you would have to multiply 5 x 100 which comes out to be a wall area of about 500 sqft. For the second wall, the wall area would be 5 x 50 = 250 sqft. We now need to add both these areas twice which comes out to be 1500 sqft. If you divide this area by 10.67 which is the area of a standard block, you would get about 141 blocks which is the actual no. of blocks required to build such a fence. Don’t just multiply 50 x 100 and get 489 blocks as the answer as that would be wrong.

How do you calculate building blocks?

You use the following formulas. Be mindful to convert feet to inches and vice versa.

Total wall area of one wall = Length of one wall x Height of one wall

Total wall area of all the walls = Sum of wall areas of all walls

The total area of one block = Length of one block x Height of one block = 16″ x 8″ / 12″= 10.67 ( I have given the size of the standard block here. If you are using different size blocks then you would need to calculate their area by multiplying their length and height. Do not use the depth of the block in this formula as it will give you false results).

Total no. of blocks required = Total area of all walls / Area of one block

Note: This is a rough method used by builders, contractors, and masons. To calculate the exact no. of blocks to the dot you should see this video.
