Brick Calculator
Calculate the number of bricks and mortar bags needed for your wall — with brick size presets, waste factor, and cost estimates.
Brick count includes 5% waste. Mortar estimate assumes standard 3/8" joints. Cost range covers common clay bricks — specialty bricks may cost more.
How It Works
This calculator determines how many bricks you need based on your wall dimensions, brick size, and waste percentage. It also estimates mortar bags and material cost.
Formula: Total Bricks = Wall Length (ft) × Wall Height (ft) × Bricks Per Sq Ft × (1 + Waste%). Mortar bags = Total Bricks ÷ 1,000 × 7 (80 lb Type S bags).
The bricks-per-square-foot value includes standard 3/8" mortar joints. Waste accounts for breakage and cuts around corners and openings.
Frequently Asked Questions
How many bricks do I need per square foot?
It depends on the brick size. Standard bricks require about 7 per square foot with mortar joints. Modular bricks need about 6.86, queen size about 5.76, and king size about 4.8 per square foot. These counts include standard 3/8-inch mortar joints.
How much mortar do I need for bricks?
A general rule is about 7 bags of 80 lb Type S mortar per 1,000 bricks. This assumes standard 3/8-inch mortar joints on a single-wythe wall. Thicker joints or double-wythe walls will require more mortar.
How much waste should I plan for with bricks?
Plan for 5% waste on simple, straight walls. Increase to 10% for walls with many openings (windows, doors) or corners. Complex patterns like herringbone or projects requiring many cuts may need 10-15% waste.
How much does a brick cost?
Common clay bricks cost $0.50-$1.50 each depending on type, color, and region. Standard red clay bricks are on the lower end, while specialty face bricks, clinker bricks, or handmade bricks can cost $1.00-$1.50 or more each.
How do I calculate bricks for a wall with openings?
Calculate the total wall area (length × height), then subtract the area of all openings (doors, windows). Enter the net wall dimensions into this calculator. The waste factor will help cover any extra cuts needed around openings.
