How many bricks per square foot?

Standard brick (3.5"×8"): 7 bricks per sq ft. Modular brick (3.5"×7.5"): 6.5 bricks per sq ft. Includes 3/8" mortar joints. Calculate wall area (length × height) × bricks per sq ft.

What is standard brick size?

Standard: 3.5"H × 2.25"W × 8"L. Modular: 3.5" × 2.25" × 7.5". Jumbo: 3.5" × 2.75" × 8". Norman: 3.5" × 2.25" × 11.5". Sizes include mortar joint in calculations.

How much do bricks cost?

Common red brick: $0.50-1.00 each. Face brick: $0.75-1.50 each. Engineering brick: $1.00-2.00. Per sq ft installed: $10-25 including materials and labor.

How much mortar do I need?

One 80lb bag covers 35-40 bricks. For 1000 bricks, need 25-30 bags of mortar. Type N mortar for above-ground walls, Type S for below-ground or high-strength applications.
