Wall area = 20 × 4 = 80 sq ft. Bricks/ft² = 144 / (8.375 × 2.625) = 6.55. Total = 80 × 6.55 × 1 × 1.1 = 576 bricks. Mortar = 576/50 = 12 bags. Cost = 576 × $0.75 = $432.

Wall area = 30 × 8 = 240 sq ft. Bricks/ft² = 6.55. Total = 240 × 6.55 × 2 × 1.1 = 3,458 bricks. Mortar = 3,458/50 = 70 bags. Cost = 3,458 × $0.75 = $2,594.

Frequently Asked Questions

Q

How many bricks do I need per square foot?

For standard bricks (8 × 2.25 in) with 3/8" mortar joints, you need about 6.55 bricks per square foot for a single-wythe wall. Double that for a double-wythe wall. Modular bricks (7.625 × 2.25 in) need about 6.86 per sq ft.

  • Standard brick (8" × 2.25"): 6.55 bricks/ft² with 3/8" mortar joints
  • Modular brick (7.625" × 2.25"): 6.86 bricks/ft² with 3/8" joints
  • King-size brick (9.625" × 2.75"): 4.61 bricks/ft²
  • Always add 10–15% waste for cuts, breakage, and pattern matching
  • Herringbone or complex patterns can require up to 20% extra bricks

Q

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

You need approximately 20 bags (80 lb each) of mortar mix per 1,000 standard bricks. That is roughly 1 bag per 50 bricks. Also need about 10 cubic feet of sand per 1,000 bricks.

  • 1 bag (80 lb) of Type S mortar covers approximately 50 standard bricks
  • Type N mortar ($8–12/bag) is best for above-grade walls and veneer
  • Type S mortar ($9–13/bag) is best for below-grade and high-wind areas
  • Sand requirement: approximately 10 ft³ per 1,000 bricks ($25–40)
  • Cold weather slows curing – use winter-grade mortar below 40°F
Q

How much does a brick wall cost per square foot?

Brick wall material costs $5-15 per square foot. Bricks: $0.50-1.50 each ($3-10/sq ft), mortar: $0.50-1.00/sq ft, labor: $10-25/sq ft. Total installed cost: $15-40 per square foot for a single-wythe wall.

  • Standard clay bricks: $0.50–$0.75 each ($3.25–$4.90/ft²)
  • Facing/decorative bricks: $1.00–$1.50 each ($6.55–$9.83/ft²)
  • Mortar materials: approximately $0.50–$1.00/ft² (bags + sand)
  • Professional mason labor: $10–$25/ft² depending on region and complexity
  • A 100 ft² garden wall (DIY): roughly $500–$800 in materials only
Wall TypeMaterial Cost/ft²Total Installed/ft²
Single Wythe (veneer)$5–$10$15–$30
Double Wythe (structural)$10–$20$30–$50
Brick Patio (flat)$4–$8$12–$25
Q

What is the difference between single and double wythe?

Single wythe is one brick thick (about 4 inches), used for veneer and non-structural walls. Double wythe is two bricks thick (about 8 inches), used for structural walls and requires twice the materials.

  • Single wythe: 3.75–4" thick – veneer only, needs backing wall or support
  • Double wythe: 8–9" thick – load-bearing, used in structural applications
  • Double wythe uses 2× the bricks and ~2.5× the mortar of single wythe
  • Most modern homes use single-wythe brick veneer over wood or steel framing
  • Older buildings (pre-1950) commonly used multi-wythe solid brick construction
