Standard brick (3.75" × 2.25" × 8") requires about 6.75 bricks per square foot for a single-wythe wall with 3/8-inch mortar joints. For a patio, use 4.5 bricks per square foot flat-laid.

Q: How much mortar do I need for 1,000 bricks?

For every 1,000 standard bricks in a wall, you need approximately 10 cubic feet of mortar mix, or about 7 bags of 60lb mortar mix.
