Brick Quantity Calculator The calculator instantly shows you the total number of bricks needed for your wall.
You can even find out the number of bricks for multiple walls by repeating the process for each one and then adding the totals together.
Brick Calculation Formula (Explained Simply)
For the curious minds who wonder what happens behind the magic, here’s the simple formula the calculator uses. Don’t worry, it’s not scary!
The general formula is:
Number of Bricks = (Wall Area) / (Brick Area + Mortar Gap)
Let’s break that down into plain English:
- Wall Area: This is the total surface you want to cover with bricks. You find it by multiplying the Wall Length by the Wall Height.
- Brick Area: This is the face of one brick. You find it by multiplying the Brick Length by the Brick Height.
- Mortar Gap: This accounts for the space the cement takes up. The calculator adds a little extra to the brick’s size to make room for the mortar.
A Simple Example:
Brick Quantity Calculator If your wall is 10 feet wide and 8 feet tall, the wall area is 80 square feet. If each brick is 8 inches long and 4 inches high, the calculator will figure out that you need around 1,400 bricks, including space for the mortar.
Visualizing Your Brick Needs
The chart below helps you visualize how brick quantity changes with wall size and brick dimensions. It’s a quick way to see the relationship at a glance!

As you can see from the dummy data, as the wall area gets bigger, the number of bricks needed increases in a straight line. A 50 sq. ft wall needs about 700 bricks, while a 200 sq. ft wall needs around 2,800 bricks.
Different Types of Bricks (With Examples)
Brick Quantity Calculator Did you know bricks come in different types? The kind of brick you choose can change the look, strength, and cost of your project. Here are some common ones:
- Common Burnt Clay Bricks: These are the classic red bricks you see everywhere. They are great for building most homes and walls.
- Fly Ash Bricks: These are eco-friendly bricks made from waste. They are very strong and good for the planet.
- Concrete Bricks: Made from solid concrete, these are often used for fences or decorative walls because they can be made in different colors.
- Hollow Bricks: These are lightweight bricks with holes in them. They are excellent for keeping heat out, making your house cooler.
- Engineering Bricks: These are the super-strong superheroes of bricks! They are used in places that need extra strength and water resistance, like basements or drainage channels.
Each brick type has different sizes, so the calculator adjusts automatically when you enter the dimensions.
Standard Brick Sizes (Global Examples)
A brick isn’t the same size everywhere in the world! This is why measuring your bricks is so important. Here are some standard sizes from different regions:
- India: 190 mm × 90 mm × 90 mm
- USA: 194 mm × 92 mm × 57 mm
- UK: 215 mm × 102.5 mm × 65 mm
- Australia: 230 mm × 110 mm × 76 mm
Different regions use different brick sizes, so always measure before calculating. The great thing about the Brick Quantity Calculator is that it can work with any size you enter.
Mortar Thickness and Its Impact
What holds the bricks together? It’s the mortar! Mortar is a mix of cement, sand, and water that acts like a powerful glue. The thickness of this mortar joint affects how many bricks you will need.
- Typical mortar thickness is about 10 mm (or 1 cm).
- More mortar = fewer bricks. Thicker mortar lines mean each brick takes up more space, so you need fewer bricks to cover the wall.
- Less mortar = more bricks. Thinner mortar lines mean you can fit more bricks in the same wall area.
Our calculator lets you adjust the mortar thickness to get the most accurate count possible.

How to Calculate Brick Quantity for Multiple Walls
Building a room or a whole house? You’ll have more than one wall. Figuring out the total bricks is easy!
Step 1: Measure the length and height of each wall separately.
Step 2: Use the Brick Quantity Calculator for each wall to find out how many bricks it needs.
Step 3: Add the totals for all the walls together to get the number for your full project.
Fun Tip: You can even calculate for fences, rooms, or garden walls! Just treat each section as a separate wall.
Wastage and Extra Bricks
Bricks can break during transport or handling. Sometimes, you need to cut a brick to fit in a corner. This is why it’s always smart to buy a few extra bricks.
It is recommended to add 5–10% extra bricks for wastage and cutting.
Example: If your calculation says you need 1,000 bricks, you should buy around 1,050 to 1,100 bricks to stay safe. This small extra cost can save you from big headaches later!

Common Mistakes to Avoid
When calculating bricks, people sometimes make small errors that lead to big problems. Here’s what to watch out for:
- Not Including Mortar Gap: Forgetting the mortar will make you think you need more bricks than you actually do.
- Forgetting Openings: If your wall has a door or a window, you don’t need bricks for that space! Remember to subtract it.
- Mixing Different Brick Sizes: Make sure all your bricks are the same size for the calculation. Don’t mix and match sizes in one calculation.
- Not Adding Extra for Wastage: Always remember to add that 5-10% extra for broken or cut bricks.
Brick Calculation for Openings (Doors & Windows)
Walls aren’t just solid rectangles. They have doors and windows! Here’s how to account for them.
Step 1: Calculate the total wall area (Length x Height).
Step 2: Calculate the area of all doors and windows on that wall (Height x Width for each).
Step 3: Subtract the total door/window area from the total wall area. This gives you the net wall area that needs bricks.
Step 4: Use the formula or calculator with this new net area.
Example:
- Total Wall Area = 120 sq. ft
- Door Area = 20 sq. ft
- Net Area for Bricks = 100 sq. ft
- Brick Count ≈ 1,300 bricks
FAQs (Frequently Asked Questions)
How do I calculate the number of bricks for my wall?
You can use the formula (Wall Area / (Brick Area + Mortar Gap)) or, much easier, use our online Brick Quantity Calculator by entering your wall and brick sizes.
What is the formula for brick calculation?
The basic formula is: Number of Bricks = (Wall Length x Wall Height) / ((Brick Length x Brick Height) + Mortar Gap).
How do I include mortar in the calculation?
Our calculator has a special field for mortar thickness. If you’re calculating manually, you add the mortar thickness to the brick’s length and height before calculating its area.
