Brick Calculator
Estimate the number of bricks, mortar bags, and pallets needed for single or double wythe masonry walls, deducting door and window openings.
Calculation Results
Effective wall area after deducting doors, windows, and openings.
Total number of individual facing bricks required including waste.
Standard supplier delivery cubes (typically 500 bricks per wrapped cube).
Pre-mixed 80 lb bags of Type N masonry mortar (approx. 8.5 bags per 1,000 modular bricks).
How This Calculator Works
Follow these steps to estimate bricks for your project:
- Select Brick Size: Modular is standard for commercial and classic residential homes; King size is common for modern cost-effective home facades.
- Enter Dimensions: Input wall length and height.
- Deduct Wall Openings: Enter total square footage of all windows, entry doors, and garage headers to avoid over-ordering.
- Select Structure: Choose single-wythe for siding veneer or double-wythe for freestanding solid structural walls.
- Review Delivery Takeoff: The calculator outputs total individual bricks, pallet cubes (500 bricks per strap), and 80lb mortar bags.
Formula & Calculations
Brick calculations are determined by dividing the net wall surface area by the nominal face area of the chosen brick type (incorporating the 3/8-inch mortar joint):
1. Brick Coverage Multipliers (Per Square Foot)
- Modular (7-5/8" × 2-1/4"): Requires
6.75 bricks/sq ft(3 courses = exactly 8 inches in height). - Standard (8" × 2-1/4"): Requires
6.55 bricks/sq ft. - King Size (9-5/8" × 2-5/8"): Requires
4.75 bricks/sq ft(popular for residential veneer because it requires 30% fewer bricks). - Queen Size (7-5/8" × 2-3/4"): Requires
5.65 bricks/sq ft. - Utility (11-5/8" × 3-5/8"): Requires
3.00 bricks/sq ft.
2. Wythe Thickness Factor
A single-wythe veneer is one brick thick (approx. 4 inches). Structural load-bearing brick walls and historic masonry consist of two structural layers tied together (double wythe), doubling the brick and mortar takeoff.
3. Mortar Requirements
Laying 1,000 modular bricks requires approximately 7.0 cubic feet of wet mortar. This equals 8.5 eighty-pound bags of Type N mortar mix.

Frequently Asked Questions
How many standard modular bricks are in a square foot of wall?
There are exactly 6.75 modular bricks per square foot of wall when laid with standard 3/8-inch mortar joints. Three vertical courses of modular bricks equal exactly 8 inches in height.
How many bricks are on a standard pallet or cube?
In the United States, a standard factory-strapped cube contains approximately 500 to 525 modular bricks and weighs between 2,000 and 2,400 lbs depending on whether the bricks are solid or cored with holes.
Why do residential builders prefer King Size bricks over Modular?
King size bricks are longer (9-5/8") and taller (2-5/8"). Only 4.75 King bricks are needed per square foot compared to 6.75 Modular bricks. This reduces the total number of bricks laid by approximately 30%, saving significant mason labor and mortar costs.
What type of mortar should be used for exterior brick walls?
ASTM C270 Type N mortar is the industry standard for exterior brick veneer. It provides a balanced compressive strength of 750 PSI with superior water resistance, flexibility, and thermal expansion properties.
How much waste should I budget for brickwork?
Budget 10% waste for straightforward rectangular walls. For complex designs with gable peaks, window arches, soldier courses, or intricate herringbone accents, budget 12% to 15% to accommodate angled cuts and minor shipping chipping.
What is the difference between single wythe and double wythe brick walls?
A single wythe wall is a single continuous layer of masonry (standard 4-inch veneer tied back to wood or metal framing). A double wythe wall consists of two parallel brick tiers bonded together, forming an 8-inch or 9-inch solid masonry structural wall.
