How This Tool Works
Enter your wall's length and height to calculate the number of bricks needed, adjusting the bricks-per-square-foot rate for your specific brick size.
Formula & Method
Wall area = length × height. Bricks needed = area × bricks per sq ft (default 7 for standard modular brick), plus your waste factor.
Example Calculation
A 20 ft long, 6 ft high wall (120 sq ft) at 7 bricks per sq ft with 10% waste needs about 924 bricks.
Frequently Asked Questions
How many bricks are in a square foot of wall?+
Standard modular brick with 3/8" mortar joints averages about 7 bricks per square foot of wall face.
Does this include mortar?+
No, this calculates brick count only. Mortar needs vary by joint size and brick type — typically about 3 bags of mortar mix per 100 bricks as a rough guide.
Should I order extra bricks?+
Yes, a 10% waste allowance covers cuts and breakage. For irregular walls or intricate patterns, consider 15%.
