Calculation Results
Calculated using verified construction formula: Bricks = Wall Area (sq ft) * (144 / ( (Brick Length + Joint) * (Brick Height + Joint) )) * (1 + Waste Margin / 100)
Quick Summary
The Brick Calculator computes exact brick quantities, mortar mix bags, total brick weight in tons, and material cost estimates for single-wythe brick veneer walls, retaining walls, fireplaces, and brick pavers.
- Total Brick Count: Computes exact modular brick count including 3/8-inch mortar joints.
- Mortar Bag Estimates: Calculates 80lb pre-mix masonry mortar bags required.
- Waste Allowance: Includes 10% safety margin for half-brick cuts and jobsite breakage.
How to Use the Brick Calculator
- Enter total Wall Length in feet.
- Enter total Wall Height in feet.
- Enter Mortar Joint Thickness in inches (3/8 inch standard).
- Adjust the Waste Margin (%) (10% standard).
- Click Calculate to view brick count, mortar bags, weight, and material cost.
Brick Calculator Formula & Method
This tool utilizes verified construction geometric formulas to compute material requirements:
Bricks / Sq Ft = 144 / Effective Brick Area (sq in)
Total Bricks = (Wall Length * Wall Height * Bricks / Sq Ft) * (1 + Waste Margin / 100)
Where:
- Standard Modular Brick: 2-1/4 inches high by 8 inches long by 3-5/8 inches deep.
- Mortar Joint: Standard 3/8-inch (0.375 in) gap filled with Type N or Type S masonry mortar.
- Bricks per Sq Ft: Standard modular brick yields 6.85 bricks per square foot.
Worked Example
Example: 20ft Long * 8ft High Wall (3/8 Mortar Joint) with 10% Waste
- Wall Face Area: 20 ft * 8 ft = 160 sq ft
- Effective Brick Size: (8.0 + 0.375) * (2.25 + 0.375) = 8.375 * 2.625 = 21.98 sq in
- Bricks Per Sq Ft: 144 / 21.98 = 6.55 bricks/sq ft
- Base Brick Count: 160 sq ft * 6.55 = 1,048 bricks
Applying the formula yields:
Total Bricks Needed (10% Waste): 1,048 * 1.10 = 1,153 Bricks
80lb Mortar Mix Bags Needed: (1,153 / 1000) * 7.5 = 9 Bags
Estimated Brick Cost: 1,153 * .85 = .05
What This Calculator Includes vs. Does Not Include
What This Calculator Includes
- Masonry Wall Scoping: Measures bricks, mortar mix bags, and pallet weights for brick veneer walls.
- Mortar Joint & Waste Inclusion: Incorporates 3/8-inch mortar joint dimensions and 10% breakage allowance.
What This Calculator Does Not Include
- Wall Ties & Metal Lintels: Galvanized brick ties and steel angle lintels.
Tips & Best Practices
- Order 10% Extra Bricks from the Same Production Batch: Brick colors vary slightly between manufacturing kilns; buying all bricks in one batch ensures uniform color matching.
- Mix Bricks from Multiple Pallets During Laying: Pulling bricks randomly from 3 different pallets blends natural color variations across the entire wall face.
Common Mistakes to Avoid
- Forgetting Mortar Joint Width in Brick Calculations: Calculating bricks based on raw brick dimensions without adding 3/8 inch for mortar joints overestimates brick count by 20%.
Frequently Asked Questions (FAQ)
How many bricks do I need for a 20x8 wall?
A 20x8 foot brick wall (160 sq ft) requires approximately 1,048 standard modular bricks (or 1,153 bricks with 10% waste).
How many bricks are in a square foot of wall?
Standard modular bricks require 6.85 bricks per square foot of wall face area (assuming 3/8-inch mortar joints).
How many bricks are on a full pallet?
A standard pallet (cube) contains 500 to 525 modular bricks and weighs approximately 2,200 to 2,400 lbs.
How many bags of mortar do I need per 1000 bricks?
It takes approximately 7 to 8 bags of 80lb pre-mix masonry mortar per 1,000 standard modular bricks.
What is the standard size of a red brick?
Standard US modular bricks measure 2-1/4 inches high by 3-5/8 inches deep by 8 inches long.
How much does a single brick cost?
Standard face bricks cost between .60 and .20 per brick ( to ,200 per thousand).
How do you calculate bricks for windows and door openings?
Calculate total gross wall surface area, subtract the square foot area of windows/doors, then multiply remaining net area by 6.85.
What type of mortar should be used for brick walls?
Type N mortar is standard for exterior above-grade brick walls; Type S is used for load-bearing or below-grade walls.
