How to Use the Brick and Mortar Calculator
Select your wall type (single or double brick), choose your measurement system, and enter the wall length and height. Pick the brick size that matches your project, specify the mortar joint thickness, and click Calculate. The tool will show you the exact number of bricks needed (with waste allowance) and the volume of mortar required.
Planning Tips for Brick Walls
- Always order 10-15% extra bricks to account for cuts, breakage, and future repairs.
- Standard mortar joint thickness is 3/8" (10mm), but check your project specifications.
- Double brick walls require roughly twice the materials plus mortar for the center joint.
- Consider ordering all bricks from the same batch to ensure consistent color matching.
