Understanding Brick Calculations
Brick calculations depend on the brick size, mortar joint thickness, and project type. Standard modular bricks require approximately 7 bricks per square foot for walls and 4.5 pavers per square foot for flat applications.
Brick Sizes and Coverage
| Brick Type | Size (L x H x W) | Bricks per Sq Ft |
|---|---|---|
| Modular | 7-5/8" x 2-1/4" x 3-5/8" | 6.86 (wall) |
| Standard | 8" x 2-1/4" x 3-3/4" | 6.55 (wall) |
| Queen | 7-5/8" x 2-3/4" x 2-3/4" | 5.76 (wall) |
| King | 9-5/8" x 2-5/8" x 2-3/4" | 4.8 (wall) |
| Paver | 8" x 4" x 2-1/4" | 4.5 (flat) |
Mortar Requirements
| Project Type | Mortar per 100 Bricks | Notes |
|---|---|---|
| Single Wythe Wall | 7-8 bags (60 lb) | Type S or N mortar |
| Double Wythe Wall | 10-12 bags (60 lb) | Includes collar joint |
| Paver (Sand Set) | N/A | Use polymeric sand |
| Paver (Mortared) | 3-4 bags (60 lb) | For permanent install |
Popular Brick Patterns
- Running Bond: Most common, bricks offset by half (5% waste)
- Stack Bond: Bricks aligned vertically (minimal waste)
- Herringbone: 45 or 90 degree angles (10-15% waste)
- Basket Weave: Pairs of bricks alternate direction (5-10% waste)
- Flemish Bond: Alternating headers and stretchers (decorative walls)
Brick Buying Tips
- Always buy 10% extra for cuts, breakage, and future repairs
- Order all bricks from the same lot for color consistency
- Check for chips, cracks, and color variations before accepting delivery
- Store bricks off the ground, covered, and away from moisture
- Use appropriate mortar type for your application and climate
- Consider hiring a professional for structural brick walls
Mortar Types
Type M: High strength, below-grade applications. Type S: General purpose, good for most walls. Type N: Medium strength, above-grade exterior. Type O: Low strength, interior non-load bearing.

Frequently Asked Questions
How accurate are the results?
The Brick applies a standard formula to your inputs — accuracy depends on how precisely you measure those inputs. For planning and estimation, results are reliable. For high-stakes or professional decisions, cross-check the output with a domain expert or primary source.
Can I use this on mobile?
Yes — the calculator is designed to work on any device. For complex multi-input calculations on small screens, landscape orientation gives more room to see all fields and results simultaneously.
How should I interpret the Brick output?
The result is a calculated estimate based on the formula and your inputs. Compare it against the reference values or benchmarks shown on this page to understand whether your result is high, low, or typical. For decisions with real consequences, use the output as one data point alongside direct measurement and professional advice.
When should I use a different approach?
Use this calculator for quick, formula-based estimates. If your situation involves multiple interacting variables, time-varying inputs, or safety-critical decisions, consider a dedicated software tool, professional consultation, or direct measurement. Calculators are most reliable within their stated assumptions — check that your scenario matches those assumptions before relying on the output.
