Block Calculator
Our block calculator helps you easily estimate the number of blocks required to build your wall. Simply enter the height and length of your wall in meters, and the calculator will determine the total area and the approximate number of blocks you’ll need. The calculation includes a 10mm mortar joint for accuracy.
How It Works
- Input: Enter the height and length of the wall in meters.
- Calculation: The calculator multiplies the height and length to get the area of the wall. Based on an average block size covering 0.2 square meters, it will estimate the number of blocks needed, rounding up to ensure you have enough for your project.
This tool simplifies your planning process by providing accurate block estimates in just a few clicks.
