Block Wall Calculator: Accurate Measurements & Cost Estimates

This tool calculates the number of blocks you need to build a wall based on your specified dimensions.

Block Wall Calculator

This calculator helps you determine the number of blocks needed to build a wall based on the wall’s dimensions and the size of each block, plus the thickness of the mortar.

How to Use the Calculator:

  1. Input the wall length in meters.
  2. Input the wall height in meters.
  3. Input the block length in meters.
  4. Input the block height in meters.
  5. Input the mortar thickness in meters.
  6. Click “Calculate” to get the total number of blocks needed.

Explanation:

The calculator works by determining the effective area of each block including the mortar thickness, and then divides the total wall area by this effective block area to get the number of blocks needed. The result is rounded up to account for whole blocks.

Limitations:

  • This calculator assumes uniform block and mortar dimensions.
  • It does not account for special patterns or designs.
  • It does not include waste or breakage.
