Concrete Block Calculator
Calculate how many concrete blocks you need for your construction project with our comprehensive calculator. Determine blocks, materials, and costs for walls and structures.
Step 1: Wall Specifications
Understanding Wall Dimensions
Standard concrete blocks are typically 20cm tall and 40cm long. Wall thickness can vary based on structural requirements and insulation needs.
Step 2: Block & Material Parameters
About Mortar Joints
Mortar joints are typically 10mm thick. Thicker joints can affect the number of blocks needed as they reduce the effective coverage area of each block.

Block Calculation Breakdown
Block Calculation Formula
Blocks = (Wall Length / (Block Length + Mortar)) × (Wall Height / (Block Height + Mortar)) × Wall Thickness Factor
To calculate blocks needed: Divide wall dimensions by block dimensions (including mortar joints), then multiply the results and apply wastage percentage.
