Masonry Brick, Mortar Mix & Bag Calculator
Calculate brick quantities, mortar volume (Type N, S, M), cement bags, masonry sand tons, and pallet cubes for single and double wythe walls.
| Material Element | Quantity Required | Packaging & Trade Standard |
|---|---|---|
| Net Wall Surface Area | - | Gross wall area minus openings |
| Brick Quantities | - | Net bricks + waste allowance |
| Pre-Mixed Masonry Mortar Bags (80 lb) | - | Approx 1 bag per 35 to 40 standard bricks |
| Site-Mixed Mortar: Masonry Cement (70 lb) | - | 1 bag masonry cement per 240 lbs sand |
| Site-Mixed Mortar: Washed Masonry Sand | - | Clean angular plaster/masonry sand |
| Corrugated Metal Wall Ties | - | 1 tie every 2.67 sq ft (16" vertical × 24" horizontal) |

How to Use the Masonry Brick & Mortar Ratio Calculator
Input Wall Dimensions & Openings
Enter total wall length, height, and subtract window and door openings to establish net surface area.
Select Brick Size & Wythe
Choose Standard Modular, Queen, King, or Utility bricks, and select single veneer or double solid masonry.
Choose Mortar Specification (Type N/S)
Select Type N for above-grade exterior walls or Type S for high-wind, structural, or below-grade masonry.
Review Pallet Cubes & Mortar
Get exact commercial order quantities for brick cubes (approx 500 bricks per pallet) and pre-mixed mortar bags.
Engineering Reference & Technical Manual
Masonry brick veneer and structural load-bearing brick walls provide exceptional thermal mass, fire resistance, acoustic dampening, and aesthetic permanence. Under ASTM C216 (Facing Brick) standards, a modular brick has nominal dimensions of $4 times 2^{2/3} times 8$ inches (including a $3/8$-inch mortar joint), yielding exactly 6.75 bricks per square foot of wall face.
Mortar selection is governed by ASTM C270 using the classic MaSoN wOrK mnemonic (Types M, S, N, O, K in descending order of compressive strength). Type N (750 PSI) is the industry standard for exterior above-grade veneer walls, offering the ideal balance of flexural bond strength and elasticity to accommodate building movement. Type S (1,800 PSI) is specified for high lateral wind loads, seismic zones, retaining walls, and below-grade foundations.
Mortar volume estimating is critical to preventing project shutdowns. On average, 1,000 standard modular bricks require approximately 7 bags of 80-lb pre-mixed mortar (or 1 ton of masonry sand and 7.5 bags of 70-lb masonry cement). Brick veneer tied to timber or light-gauge steel framing must be anchored with corrosion-resistant corrugated galvanized wall ties spaced at least every 2.67 square feet under IRC Section R703.8.

Frequently Asked Questions
A standard pallet (or "cube") of modular brick typically contains 500 to 525 bricks and weighs approximately 2,000 to 2,400 lbs depending on the clay core holes.
Type N mortar has a minimum compressive strength of 750 PSI and is best suited for above-grade exterior walls and chimneys. Type S has a compressive strength of 1,800 PSI and is required for below-grade walls, foundations, and high-wind structural applications.
For standard modular bricks with 3/8-inch joints, you need approximately 25 to 28 bags of 80-lb pre-mixed mortar (or 1 ton of masonry sand plus 7 to 8 bags of 70-lb masonry cement) per 1,000 bricks.
