Frequently Asked Questions

A brick calculator estimates the number of bricks and mortar needed for a wall project. By entering wall dimensions, brick type, mortar joint thickness, and bond pattern, the calculator tells you how many bricks you need including a 10% waste factor and estimates the mortar quantity and material cost.
A standard modular brick (3.625 x 2.25 x 7.625 in) with a 3/8 inch mortar joint covers approximately 7 bricks per square foot. Queen bricks cover about 5.8 per sq ft, king bricks about 5.4 per sq ft, engineer bricks about 6.2 per sq ft, and closure bricks about 5.5 per sq ft. These values change slightly with different mortar joint thicknesses.
As a general rule, one 60 lb bag of mortar mix covers approximately 35–40 bricks, and one 80 lb bag covers approximately 45–50 bricks. For standard modular bricks, you need about 3 bags of mortar mix per 100 bricks. These estimates can vary based on joint thickness, waste, and brick type.
Stretcher bond has all bricks laid lengthwise in overlapping rows. Running bond offsets each row by half a brick. Stack bond aligns all bricks vertically and horizontally without offset. Herringbone lays bricks at 45° angles in a zigzag pattern. Stretcher and running bonds are the most common for structural walls, while stack and herringbone are decorative.
Yes, always add a waste factor to account for broken bricks, cuts around openings, and other installation losses. Our calculator automatically adds a 10% waste factor. For complex patterns like herringbone or walls with many openings, consider increasing the waste factor to 15–20%.
