Calculate the number of bricks, mortar, and materials needed for your wall project. Get accurate estimates including waste allowance, bond patterns, and material costs.
Most common, bricks offset by half
0.0 sq ft × 7.0 bricks/sq ft
• Standard modular bricks are most common (7.625" × 2.25")
• 3/8" mortar joints are typical for most applications
• Add 10-15% waste for cutting and breakage
• Running bond is easiest for DIY projects
• 1 bag of mortar covers approximately 142 bricks

The number of bricks needed per square foot depends on the brick size and mortar joint thickness. Here are the standard coverage rates with 3/8" mortar joints:
| Brick Type | Per Sq Ft |
|---|---|
| Standard Modular | 7 |
| Queen | 6.5 |
| King | 5.5 |
| Engineer | 7 |
| Roman | 6 |
Mortar joint thickness significantly affects brick coverage:
3/8" joints (standard)
Base coverage rates apply
1/2" joints
Use 8% fewer bricks
5/8" joints
Use 15% fewer bricks
The bond pattern affects both aesthetics and the amount of waste material. More complex patterns require more cutting and waste:
Most common, bricks offset by half
Bricks stacked vertically
Alternating headers and stretchers
Alternating courses of headers and stretchers
Diagonal V-pattern
Best for beginners, minimal waste, fastest installation. Each course offsets by half a brick.
Traditional patterns with headers (short ends) and stretchers (long sides). Requires more skill.
Most complex, typically used for patios and walkways. Requires significant cutting expertise.
| Brick Type | Actual Size (W × H) | Per Sq Ft | Common Use |
|---|---|---|---|
| Standard Modular | 7.625" × 2.25" | 7 | Most common residential |
| Queen | 7.625" × 2.75" | 6.5 | Commercial buildings |
| King | 9.625" × 2.625" | 5.5 | Large commercial walls |
| Engineer | 7.625" × 2.75" | 7 | Structural applications |
| Roman | 11.625" × 1.625" | 6 | Decorative facades |
Note: All sizes are nominal dimensions. Actual dimensions may vary slightly by manufacturer.
General purpose, above grade walls. Medium strength (750 psi).
High strength (1800 psi). Best for exterior walls, below grade, and high wind areas.
Maximum strength (2500 psi). For below grade retaining walls and foundations.
Standard Coverage (Type S):
• 1 bag covers approximately 142 bricks
• 7 bags per 1000 bricks
• 1 bag = 60-80 lbs depending on brand
Sand is mixed with mortar cement (typically 3:1 ratio):
• 1 cubic foot sand per 100 bricks
• Use clean masonry sand
• Dry sand recommended for accurate mixing
For standard modular bricks: 7 bricks/sq ft with 3/8" joints, 6.5 bricks/sq ft with 1/2" joints, and 6 bricks/sq ft with 5/8" joints. Larger joints reduce brick count but may affect structural integrity.
Face bricks have a finished appearance on one or more sides and are used for exposed surfaces. Common bricks are rougher and cheaper, typically used for structural purposes where they won't be visible. Face bricks cost 2-3 times more.
Add 10-15% for standard running bond with straight walls. Complex patterns like herringbone need 15-20%. Include extra for cuts around openings, breakage during transport, and future repairs. Always order from the same lot to ensure color matching.
Thicker joints (1/2" to 5/8") require less bricks but more mortar, creating a different aesthetic. Standard 3/8" joints provide best balance of strength and appearance. Building codes typically require 3/8" minimum for structural walls.
Running bond is easiest for DIY and has minimal waste. Stack bond looks modern but is weaker structurally. Flemish and English bonds are traditional and strong but require more skill. Herringbone is best for patios, not vertical walls.
Wait 24-48 hours for mortar to cure. Use a stiff brush and water first. For stubborn mortar stains, use a mild muriatic acid solution (1:10 ratio). Always wet the wall first, apply acid, scrub, and rinse thoroughly. Wear protective equipment.
Standard pallets typically hold 500-600 modular bricks, depending on size and manufacturer. Larger bricks like kings may have 400-450 per pallet. Always verify with your supplier as pallet sizes vary.
While possible for decorative purposes, mixing sizes complicates installation and mortar joint alignment. If mixing, plan the pattern carefully and add 20-25% waste. Consult a mason for structural walls.
