How brick counts are calculated
modular: 7.0/sq ft · queen: 5.8 · king: 4.8 (⅜″ joints, single wythe)
A 20 × 6 ft garden wall (120 sq ft) in modular brick needs 840 bricks before waste — order 925 at 10%. Counts are for a single-wythe (one brick thick) wall; a double-wythe structural wall doubles it.
Bricks per square foot by size
| Brick | Face size | Per sq ft | Per 100 sq ft |
|---|---|---|---|
| Modular | 7⅝ × 2¼″ | 7.0 | 700 |
| Standard | 8 × 2¼″ | 6.55 | 655 |
| Queen | 7⅝ × 2¾″ | 5.8 | 580 |
| King | 9⅝ × 2⅝″ | 4.8 | 480 |
Ordering tips
- One production run: brick color varies batch to batch — order the whole job at once and blend from multiple cubes as you lay.
- Don't forget openings: subtract windows and doors from the wall area, but keep the waste factor — arches and cuts eat bricks.
- Mortar and sand: the result above uses premix bags; for site-mixing quantities see the mortar calculator, and pair it with the sand calculator.
- Building with block instead? The concrete block calculator handles CMUs.
Frequently asked questions
How many bricks per square foot of wall?+
Modular bricks (7⅝ × 2¼ inches) run about 7 per square foot of single-wythe wall with ⅜-inch joints. Queen bricks run ~5.8 per square foot and king bricks ~4.8, which is why larger units go up faster and cheaper.
How many bricks do I need for a 100 square foot wall?+
About 700 modular bricks before waste — order 735–770 with a 5–10% waste factor for cuts and breakage. The same wall in king brick needs about 480 bricks.
How much does a brick wall cost?+
Standard modular bricks cost $0.50–$1.00 each ($350–$700 per 1,000); face brick with special finishes runs higher. With mortar, sand and accessories, DIY materials land around $4–$8 per square foot; professionally laid walls run $25–$45 per square foot.
How many bricks come on a pallet?+
A standard pallet ("cube") holds around 500–525 modular bricks and weighs about 2,000 lb. Suppliers sell by the cube for full pallets, so a 700-brick job means ordering a cube and a half or two cubes.
Do I need a footing for a brick wall?+
Yes — any freestanding or structural brick wall needs a concrete footing below frost depth, typically twice the wall width and at least 8–12 inches thick. Brick veneer on a house bears on the foundation ledge instead.
