How many bricks do I need per square foot?

For standard modular bricks with 3/8-inch mortar joints, you need approximately 6.75 bricks per square foot for a single wythe wall. This accounts for the mortar joint spacing between each brick.

How do I calculate bricks for a wall?

Multiply the wall height by the wall length to get total square footage, subtract window and door openings, then multiply by 6.75 bricks per square foot. Add 5-10% for waste, cuts, and breakage.

What is the standard brick size?

The standard modular brick in the US measures 3-5/8 x 2-1/4 x 7-5/8 inches. With a standard 3/8-inch mortar joint, the nominal dimensions become 4 x 2-2/3 x 8 inches, which simplifies layout calculations.

How much mortar do I need per 1,000 bricks?

You need approximately 7-9 bags (70 lb each) of pre-mixed mortar per 1,000 standard modular bricks. The exact amount depends on joint thickness, brick size, and the mason's technique.

How many bricks do I need per square foot?

Standard 8" × 2.25" brick with 3/8" mortar joint produces approximately 6.75 bricks per square foot of wall area. Modular brick is similar at 6.86 per sq ft. Queen brick (7.625" × 2.75") is about 5.76 per sq ft. King brick is about 4.5 per sq ft. Always add 5-10% waste for cuts around openings; rougher work (stack bond, intricate patterns) needs more waste.

How much mortar do I need per 1000 bricks?

Plan for 6-8 bags of mortar mix (70 lb bags) per 1000 standard bricks. Stack bond uses about 10% more mortar than running bond because all joints carry full mortar (no overlapping). Mortar mix bags typically include cement + sand pre-mixed; if buying raw cement plus sand separately, plan ~1 cubic foot of sand per bag of mortar mix equivalent.

What's the difference between standard, modular, queen, and king brick?

Standard brick is 8" × 2.25" × 3.625" — the traditional US dimension. Modular is slightly shorter at 7.625" × 2.25" × 3.625" and is now the most common in commercial work. Queen brick is wider and taller (7.625" × 2.75" × 3.125") — fewer bricks per sq ft but slightly more cost-efficient on tall walls. King brick is the largest at 9.625" × 2.75" × 3", used for fast residential veneer work — significantly fewer bricks needed but each brick is more expensive.

How fast can a mason lay brick?

Experienced masons average 60-80 bricks per hour on standard running bond exterior walls with good access. Production rate drops to 30-50 bricks/hour for stack bond, intricate patterns, or scaffolding-required work above 8 feet. New apprentices typically produce 30-45 bricks/hour. Plan labor cost accordingly — a 5,000-brick job is typically 60-85 mason-hours plus helper time for mixing and tending.

Do I need wall ties for brick veneer?

Yes — code requires wall ties (corrugated metal strips, typically galvanized) for any brick veneer wall. Minimum spacing per IBC: one tie per 2.67 sq ft of wall, with a minimum 16" horizontal and 24" vertical spacing. Ties anchor the brick veneer to the structural wall (wood-frame, CMU, or steel). Skip wall ties and the veneer will eventually separate from the substrate — code violation and a real structural problem.

Pro Tips

Order full cubes (typically 500-525 bricks per cube) rather than partial — pricing per brick is 10-20% better at full-cube quantities. Plan to use leftover bricks on the next job.
Mortar mix tip:Type N for above-grade veneer; Type S for load-bearing or below-grade work; Type M for heavy-duty structural. Don't use Type S where Type N is appropriate — Type S shrinks more and can crack veneer over time.
Order 5% extra wall ties beyond the calculation — corner conditions, jamb returns, and damaged ties during install all consume extras.
Pallet returns: Many suppliers credit $5-$15 per returned pallet. Mortar bags are NOT returnable but unopened brick pallets often are. Save your receipt and inquire when returning unused material.

How to Use This Calculator

Enter the length and height of each wall in feet, then set how many walls you are building. Choose the brick size and mortar joint thickness. If you have window or door openings, enter the count and average dimensions to subtract them from the total area. Adjust the waste factor (5-10% is typical) and select your bond pattern. The results update instantly.

Formula Used

Bricks per sq ft = 144 / ((brick length + mortar joint) x (brick height + mortar joint)). Total Bricks = Net Wall Area x Bricks per sq ft x (1 + Waste%). Mortar Bags (70 lb) = Total Bricks / 1000 x 7. Wall Ties = Net Area / 2.67.
