Calculate bricks needed for a wall. Enter wall area to get brick count, mortar bags, and material estimates with waste factor.
Brick is one of the oldest and most enduring building materials, prized for its beauty, durability, and fire resistance. Whether you're building a brick veneer on a home, a garden wall, a brick mailbox, or an accent feature, knowing exactly how many bricks to order is essential for efficient construction.
This calculator determines the number of standard modular bricks needed for your project based on wall area. Standard modular bricks measure 3-5/8" × 2-1/4" × 7-5/8" and require approximately 6.75 bricks per square foot of wall (with standard 3/8" mortar joints).
The calculator includes a waste factor for cutting, breakage during delivery, and on-site damage. It also estimates the number of mortar bags needed, so you can order all materials at once.
This data-driven approach helps contractors minimize rework, avoid delays caused by material shortages, and deliver projects on time and within the agreed budget. By quantifying this parameter precisely, construction teams can optimize material orders, reduce on-site waste, and ensure structural requirements are met safely and efficiently.
Bricks are sold by the thousand, and each pallet costs hundreds of dollars. Under-ordering means a second delivery charge and potential color lot mismatch. Over-ordering means returning heavy pallets or storing them indefinitely. This calculator gets you to the right number. Regular use of this calculation supports compliance with building codes and inspection requirements, helping projects proceed smoothly through the permitting and approval process.
Wall area (ft²) = Length × Height − Openings Bricks = Wall area × 6.75 (modular bricks per ft²) With waste: Bricks × (1 + waste %) Mortar bags ≈ Bricks ÷ 35 (80-lb bags)
Result: 1,157 bricks
Net wall area = (25 × 8) − 20 = 180 ft². Bricks = 180 × 6.75 = 1,215. With 7% waste: 1,300. Mortar: 1,300 ÷ 35 = 38 bags of 80-lb Type S masonry cement.
Modular: 3-5/8" × 2-1/4" × 7-5/8" (6.75/ft²). Queen: 3-1/8" × 2-3/4" × 9-5/8" (5.76/ft²). King: 3-5/8" × 2-5/8" × 9-5/8" (4.5/ft²). Utility: 3-5/8" × 3-5/8" × 11-5/8" (3.0/ft²). Always verify the actual brick dimensions with your supplier.
Running bond is the most common (each course offset by half a brick). Common bond adds a header course every 6th course. Flemish bond alternates headers and stretchers in each course for a decorative look. Stack bond is purely decorative and requires horizontal joint reinforcement.
Subtract the opening area but add bricks for soldier courses (upright bricks) above windows and doors, and for rowlock sills below windows. These accent courses use more bricks per linear foot than standard running bond.
Standard modular bricks: 6.75 per ft². Queen size: 5.76 per ft². King size: 4.5 per ft². These counts include standard 3/8" mortar joints.
Type N mortar is standard for above-grade brick walls. Type S is used for below-grade, structural, and high-wind areas. Type N provides better workability and is less likely to crack versus the harder Type S.
A standard pallet contains about 500 bricks and weighs approximately 2,000–2,500 lbs. Each modular brick weighs about 4–4.5 lbs. Delivery trucks typically carry 7–10 pallets.
Brick alone costs $4–$10 per square foot. Installed brick veneer (labor + materials) costs $12–$25 per square foot depending on region and complexity. Specialty or imported bricks can cost significantly more.
A structural brick wall is load-bearing (usually two wythes thick). Brick veneer is a single-wythe decorative facing attached to a structural frame or block wall. Most modern residential construction uses brick veneer.
Build corners (leads) 4–5 courses high first, checking plumb and level carefully. Then fill in between the leads using a mason's line stretched between corners. This ensures straight, plumb walls.
