That's 1,764 bricks — a serious delivery. Ask your supplier about curbside pallet drop-off.
How to Calculate How Many Bricks You Need
You know the wall size. The next question is simple: how many bricks do you actually need?
Enter your wall measurements and brick size into the calculator above to get an estimate.
The calculation starts with the area you need to cover. If your wall has doors, windows, or other openings, subtract those areas first. Then the calculator uses your brick dimensions and mortar joints to estimate the number of bricks required.
That gives you a starting number.
But wall size alone does not tell the whole story.
Brick Calculator by Wall Size
A small change in wall dimensions can change the number of bricks you need more than expected.
For example, a wall that is 10 feet wide and 6 feet high covers 60 square feet. A larger wall measuring 20 feet by 8 feet covers 160 square feet. The brick quantity increases with the area you need to cover.
This is why measuring the wall first is usually more useful than trying to guess how many bricks are needed per project.
Once you have the wall area, the next part is knowing how much space each brick actually covers.
Brick Size, Mortar, and Wall Thickness Can Change the Result
Not all bricks are the same size.
A calculator needs the dimensions of the brick you plan to use. Mortar joints also take up space between bricks, which means the final number can differ from a calculation based on brick size alone.
Wall thickness matters too.
A single-brick wall and a thicker wall may cover the same surface area but require very different quantities of bricks. Before ordering, make sure the calculator settings match the wall you are building.
Now you have a closer estimate.
The next question is the one that can prevent a frustrating problem: should you order exactly that number?
How Many Extra Bricks Should You Buy?
Usually, ordering the exact calculated number is risky.
Some bricks may break during transport or installation. Others may need to be cut to fit around corners, doors, windows, or other parts of the wall.
Buying a small number of extra bricks can help you avoid stopping the project because you are only a few bricks short.
The amount of waste depends on the project. A simple rectangular wall usually creates less waste than a design with many openings, corners, or cuts.
Once you know the approximate quantity, you can move to the next practical question: how much will those bricks cost?
Estimate the Total Cost of Your Bricks
The total brick cost depends on two numbers:
- How many bricks you need
- The price of each brick
Multiply the estimated brick quantity by the price per brick to get a basic material estimate.
Keep in mind that this does not automatically include delivery, mortar, labor, tools, or other building materials unless you add those costs separately.
The calculator gives you a useful starting point for planning. Before placing an order, check your final measurements, brick dimensions, wall thickness, and any areas that should be excluded.
Premixed Mortar vs. Site Mix
You have two choices for mortar. For small jobs, premixed bags (just add water) are easiest. For large walls, buying bulk Portland cement and masonry sand is significantly cheaper. Use the calculator above to toggle between the two and see the cost difference.
1 bag (60 lb) lays ~40 modular bricks. Best for DIY and small repairs.
1 bag Portland (94 lb) + 3 cubic feet of sand lays ~150 bricks. Best for pro masons.

Brick Calculator FAQs
How do I calculate how many bricks I need?
Measure the width and height of the wall, subtract any doors or windows, and use the brick dimensions and mortar joint size to estimate how many bricks are needed.
How many bricks are needed for a 10×10 wall?
It depends on the brick size, mortar joints, and wall thickness. A 10×10 wall covers 100 square feet, but the number of bricks required can vary.
How many bricks are in one square foot?
The answer depends on the size of the brick and the space used for mortar joints.
How many bricks are in one square metre?
Brick quantity per square metre depends on the brick dimensions and mortar thickness. Entering the exact measurements gives a more useful estimate.
Does the calculator include mortar joints?
That depends on the calculator settings. If mortar joint dimensions can be entered, use the measurements planned for your project.
What brick size should I enter?
Enter the dimensions of the actual bricks you plan to buy rather than assuming every brick uses the same standard size.
How many extra bricks should I buy?
The number depends on cuts, breakage, wall design, and the complexity of the project. Walls with more corners and openings may require more extra bricks.
How do I calculate bricks for a thicker wall?
Wall thickness changes the amount of brick required. Make sure the calculation reflects the actual wall construction rather than only the visible wall area.
Can I calculate the cost of the bricks?
Yes. Multiply the estimated number of bricks by the price of each brick. Add delivery and other material costs separately if needed.
How accurate is a brick calculator?
A brick calculator provides an estimate based on the measurements entered. The result is more reliable when the wall dimensions, openings, brick size, mortar joints, and wall thickness are entered correctly.
