### Concrete Block Calculator - Find How Many Blocks You Nee

After you have found the square footage of both your wall and your block, determining the number of blocks you need is as simple as dividing the wall square footage by the block square footage. blocks = wall sq ft block sq f Now divide the total surface area of the wall by the surface area of one block Number of blocks= surface area of Wall/Surface area of the block 91/1.0625=86 Now consider 5% wastage of concrete blocks To estimate how many blocks you'll need per row, divide the total length of the wall by the length of the block. To figure out how many rows you'll need, divide the ideal wall height by the height of the block. Make sure to account for the first row being half-buried For example, if your standard concrete block is 1 foot by 0.5 feet and is separated from its neighbours by a half-inch of mortar, then each block accounts for 1.0417 x 0.5417, or 0.5643 square feet. Step 5 Divide the total surface area of the wall by the surface area of the representative block to get the total number of blocks in the wall How to calculate the quantity / number of blocks/bricks required to construct a wall. How to calculate the quantity / number of blocks/bricks required to construct a wall  Mortar bags needed for block count. Block count: Mortar Bags Required: (add approx. 5% to the total for waste) Wall reinforcing (Ladder or Truss type) Block count: L.F. Type. 16 24 Linear Feet Required: (add approx. 5% to the total for waste) Zonolite type fill. Wall (sq ft) Block Size. Number of blocks is total wall area divided by area of one block: Hence, number of blocks is:200,359,500/101,250= 1978.86 blocks. That's approximately1,980 blocks. You may want to add a certain percentage for breakages and off-cuts. If you use good quality vibrated blocks you only need to add a little To find the total number of blocks needed for the wall, multiply the number of columns by the number of rows; don't forget to subtract a row if using cap blocks.
