Wondering how many bricks per square foot you need? A modular brick wall takes about 6.75, and that number moves with brick size and joint width.
Here is how it works for each common type, so you can order the right amount the first time.
How Many Bricks Are in a Square Foot?
A square foot of modular brick wall holds about 6.75 bricks, with a standard 3/8 inch mortar joint included. Bigger bricks cover more wall, so you need fewer of them. Smaller bricks cover less, so you need more.
Masons count bricks per sq ft with nominal sizes.
A nominal size is the real brick plus one mortar joint. That way, every brick gets its own slice of mortar in the math.
Bricks Per Square Foot Chart by Brick Type
The chart below shows typical bricks per sf for common types, assuming a 3/8 inch joint. Treat the “about” figures as close estimates, because makers vary slightly.
| Brick Type | Bricks per Sq Ft | Bricks for 100 Sq Ft |
|---|---|---|
| Modular | 6.75 | 675 |
| Standard | about 6.55 | about 655 |
| Engineer | about 5.6 | about 560 |
| Roman | 6.0 | 600 |
| Norman | 4.5 | 450 |
| Utility | 3.0 | 300 |
| King size | about 4.8 | about 480 |
| Queen size | about 4.6 | about 460 |
| UK standard (215 x 65 mm) | about 5.5 | about 550 |
These counts cover wall area only. Waste comes later in this guide.
Modular Brick Per Square Foot
Modular brick per square foot equals 6.75, and you can check it with quick math. Its nominal face measures 8 inches long and 2-2/3 inches high, which gives 21.33 square inches.
A square foot holds 144 square inches. Divide 144 by 21.33 and you land on 6.75.
Three courses stack to exactly 8 inches, so planning heights feels easy. That is why modular brick per sf is the number most builders carry in their heads. It suits houses, chimneys, and garden walls.
King and Queen Size Brick Per Square Foot
King size brick per square foot is about 4.8, and queen size brick per square foot is about 4.6. Both units are bigger than modular bricks, so each one covers more wall.
A king brick runs roughly 9-5/8 inches long and 2-5/8 inches tall. Add a 3/8 inch joint and it covers about 30 square inches. Divide 144 by 30 and you get 4.8.
A queen brick stands a touch taller, so it covers a little more. Makers differ on exact sizes, so ask your supplier for the real dimensions. A tiny change in height can shift your count more than you expect.
How Many Bricks for 100 Square Feet?
A 100 square foot wall of modular brick needs about 675 bricks before waste. Add 10 percent for extras and plan on roughly 743.
Now picture a wall with a 20 square foot window in it. You only brick 80 square feet. Multiply 80 by 6.75 and you get 540 bricks.
Add 10 percent for waste and the order rises to 594. That order is about 150 bricks smaller than the raw 100 sq feet estimate. Subtracting openings pays off.
How to Calculate Brick Per Sq Ft Yourself
To find bricks per square foot for any brick, divide 144 by the area of one brick face plus its joint. This works for every size and every joint. Follow these steps:
- Measure the wall’s length and height in feet.
- Multiply them to find the wall area.
- Subtract doors, windows, and vents.
- Multiply what remains by the bricks per sq ft for your type.
- Add 5 to 10 percent for cuts, chips, and breakage.

What Changes Your Brick Count on a Real Job?
Joint width, wall thickness, bond pattern, and waste all change the final brick count. Miss one and you could run short on delivery day.
Joint width. A wider joint means fewer bricks per square foot. A 1/2 inch joint trims the modular count a little. A thinner joint pushes it up.
Wall thickness. A double-wythe wall stacks two layers of brick. That doubles the count for the same face area.
Bond pattern. Running bond uses the base numbers. Patterns with header bricks, such as English or Flemish bond, use more because short ends face outward. Soldier courses also change things, since the bricks stand upright.
Waste. Cuts around windows, corners, and gables create scrap. A simple wall needs about 5 percent extra. A detailed one needs closer to 10 percent.
Brick Veneer Over Block: Count Both Layers
For brick veneer over a block backup wall, count the brick and the block separately. A nominal 8 x 16 inch block covers 128 square inches, or about 0.89 square foot. That works out to roughly 1.125 blocks per square foot.
Our concrete masonry calculators guides explain block sizes and quantities in detail. Read them alongside this chart and both layers will line up.

Most miscounts come from a handful of habits. Fix these and your order tightens up fast.
- Using actual size instead of nominal size. Actual sizes skip the joint, so they inflate the count.
- Forgetting openings. Doors and windows remove brick area, so subtract them first.
- Skipping waste. Even careful masons chip and cut bricks.
- Trusting the word “standard.” Check the supplier’s spec sheet before you order.
- Mixing units. Metric and imperial bricks do not match, so stay in one system.
Also ask how many bricks ship on each pallet. Then you can round your order to full pallets and avoid a second delivery fee.
Final Thoughts
Brick counts look simple, yet small details shift the total. Modular brick needs about 6.75 per square foot, while king and queen sizes need closer to 4.6 to 4.8. Subtract openings, add a waste buffer, and confirm sizes with your supplier.
Measure twice, order once, and keep a few spare bricks for future repairs.
