Construction Calculator
This blog post features a handy calculator to help you estimate the materials needed for bricklaying and wall plastering projects. Simply enter your dimensions and get the quantities of bricks, cement, and sand you'll need. The instructions below explain how it works.

How It Works
This application provides two calculators to help you estimate materials for your construction project.
Brick & Mortar Calculator
This calculator estimates the number of bricks and the quantity of cement and sand required for a brick wall.
- Inputs: You can define the dimensions of your wall (length, height, thickness), the size of your bricks, the mortar joint thickness, and the cement-to-sand ratio for your mortar.
- Calculations: The number of bricks is calculated based on the wall's total area and the area of a single brick plus a mortar joint. The mortar volume is then derived by subtracting the total volume of bricks from the total wall volume.
- Ratios and Wastage: By default, it uses a 1:6 cement-to-sand ratio for the mortar. A 33% wastage factor is also applied to account for mortar spillage and other losses during the bricklaying process. A water-to-cement ratio of 0.5 by weight is used to estimate the water requirement.
- Outputs: The results are given in pieces for bricks, 50kg bags for cement, cubic meters (m³) for sand, and liters for water.
Wall Plastering Calculator
This calculator helps you determine the amount of cement and sand needed for plastering a wall.
- Inputs: You define the length and height of the wall to be plastered, the desired plastering thickness, and the cement-to-sand ratio.
- Calculations: The total volume of plaster is calculated by multiplying the wall's area by the plaster thickness. This volume is then used to determine the required cement and sand based on the specified ratio.
- Ratios and Wastage: By default, it assumes a 1:4 cement-to-sand ratio for plastering. A 30% wastage factor is also included to account for material losses. A water-to-cement ratio of 0.5 by weight is used to estimate the water requirement.
- Outputs: The results are given in 50kg bags for cement, cubic meters (m³) for sand, and liters for water.
