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.
| Brick Size | Dimensions | Bricks per ft² |
|---|---|---|
| Standard | 8" × 2.25" × 3.75" | 6.55 |
| Modular | 7.625" × 2.25" × 3.625" | 6.86 |
| King Size | 9.625" × 2.75" × 3.625" | 4.61 |
| Utility | 11.625" × 3.625" × 3.625" | 3.00 |
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.
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.
| Wall Type | Material Cost/ft² | Total Installed/ft² |
|---|---|---|
| Single Wythe (veneer) | $5–$10 | $15–$30 |
| Double Wythe (structural) | $10–$20 | $30–$50 |
| Brick Patio (flat) | $4–$8 | $12–$25 |
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.
