Tip Order all bricks from the same production lot to ensure consistent color. Bricks from different lots can have noticeable color variations.
Pro Tip Use Type S mortar for exterior walls in harsh climates, Type N for above-grade protected walls.

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.
