Bricks for a 30 × 4 ft wall
A wall this low is a garden or seat wall, a planter edge or a short boundary wall. This wall is 120 sq ft. At 3/8 in mortar joints, the count for one layer of brick (a single wythe) is:
| Brick | Per sq ft | No waste | With 8% waste | Pallets |
|---|---|---|---|---|
| Modular (7⅝ × 2¼ in) | 6.75 | 810 | 875 | 1.8 |
| Norman (11⅝ × 2¼ in) | 4.5 | 540 | 584 | 2.0 |
| Utility (11⅝ × 3⅝ in) | 3 | 360 | 389 | 1.4 |
| Roman (11⅝ × 1⅝ in) | 6 | 720 | 778 | ask supplier |
How much waste to allow
Cuts, breakage and variation use up bricks. Use 5% for a plain straight wall, 8 to 10% for most jobs, and 15% for arches, corners and patterned work (modular brick).
| Waste | Modular bricks | Pallets |
|---|---|---|
| 0% | 810 | 1.6 |
| 5% | 851 | 1.7 |
| 8% | 875 | 1.8 |
| 10% | 891 | 1.8 |
| 15% | 932 | 1.9 |
Taking off doors and windows
Subtract the area of each opening from the wall area before you count (modular brick, 8% waste).
| Openings | Bricks |
|---|---|
| No openings | 875 |
| One door (about 21 sq ft) | 722 |
| A door and a window (about 40 sq ft) | 584 |
| A door and three windows (about 60 sq ft) | 438 |
Mortar is bought separately. Use the brick calculator for your own wall, and read how many bricks you need for the formula and joint sizes. Double walls need twice as many bricks, and walls over 4 ft need footings.
