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.
