How to calculate brick masonry & mortar cement, sand?
In this article we will discuss the most easiest way, for brick work calculation, bricks for wall calculation, mortar for brick masonry. If you are seeking an answer to how many bricks do i need or need to find bricks for patio. You landed on right blog.
Masonry is done with either bricks, blocks or stone, but for joinning, same kind of cement mortar is used. For brick masonry analysis one of standard measuring unit is adopted, which is used to calculate bricks and mortar.
There’s mainly two systems, British system & MKS system. British system brick size is 9″×4.5″×3″, on other hand in MKS system 20×10×10 cm. In standard brick masonry there’s 1350 bricks in 100 cubic feet and 500 bricks in 1 cubic meter.
In same manners, for masonry 100 cft bricks it needs 30 cft of dry mortar, while 1 cum brick masonry needs 0.30 cum of dry mortar.
How to calculate brick masonry for 100 cubic feet in mortar ratio (1:5)?
- Brick work = 100 cft
- Number of bricks used = 1350 (1350 is standard, we mention above)
- Ratio of cement mortar = (1:5)
- Sum of ratio = 1+5 = 6
Quantity of dry mortar = 30 cft (30 is std also mention above)
How to calculate quantity of cement for mortar?
(Ratio of cement / sum of ratio) × Quantity of mortar
- (1/6)×30 = 5cft of mortar = 5/1.25 = 4 bags (1 cement bag volume is 1.25 cft)
How to calculate quantity of sand for mortar?
- (Ratio of sand / sum of ratio) × quantity of mortar
- (5/6)×30 = 25 cft
or you can do it simply by multiplying cft of cement with ration of sand. Because sand is that much times more than cement.
TOTAL; BRICK= 1350, CEMENT= 4 bags, SAND= 25 cft

How to calculate brick masonry for 1 cubic meter in mortar ratio (1:6)?
- Brick work = 1 cu.m
- Number of bricks = 500
- Ratio of cement mortar = 1:6
- Sum of ratio = 7
Total quantity of dry mortar = 0.30 cum (std for 1cum B.W)
How to calculate quantity of cement?
- (Ratio of cement / sum of ratio) × quantity of mortar
- (1/7)×0.30 = 0.043 cu.m
- 0.043/0.035 = 1.228 cement bags (1 bag of cement is 0.035 cu.m)
How to calculate quantity of sand?
- (Ratio of sand / sum of ratio) × quantity of mortar
- (6/7) × 0.30 = 0.257 cu.m.
TOTAL; BRICKS= 500, CEMENT= 1.228 BAGS, SAND= 0.257 cu.m
