Brick Quantity Calculator

Whether you're building a boundary wall, a home, or laying a brick floor, knowing the exact number of bricks required is essential for planning and budgeting. Our Brick Quantity Calculator is designed to help you estimate the number of bricks needed for any construction project quickly and accurately.

This tool is especially useful for homeowners, contractors, and civil engineers who want a reliable method to calculate brick quantity based on the wall or floor area. You can calculate in square feet, square meters, or use custom brick sizes all without manual math.

How to Calculate Brick Quantity Manually?

To calculate brick quantity, the basic method is to find the volume of the wall and divide it by the volume of one brick (including mortar). The formula remains the same whether the wall is 4.5 inches, 9 inches, or even a custom thickness.

Standard Formula:

Number of Bricks = Wall Volume / Brick Volume (with mortar)

Where:

• Wall Volume = Length × Height × Thickness
• Brick Volume = (Brick Length + Mortar Thickness) × (Brick Width + Mortar Thickness) × (Brick Height + Mortar Thickness)

Always add 5% to 10% extra bricks to account for breakage and wastage.

Brick Quantity Calculator: How to Use?

Using our calculator is simple:

Step-by-Step Guide:

1. Enter wall length and height in feet, meters, or inches.
2. Select wall thickness (4.5 inch, 9 inch, or custom).
3. Choose standard brick size or enter custom dimensions.
4. Add mortar thickness and wastage percentage.
5. Click “Calculate” to get the exact number of bricks required.

Common Calculations in Feet & Meters

1. How Many Bricks Are in 100 Sq Ft?

Assuming standard 9 inch wall, standard brick size (190mm x 90mm x 90mm), and 10mm mortar:

• Wall Volume = 100 sq ft × 0.75 ft (9 inch) = 75 cu ft = 2.12 m³
• Brick Volume = 0.20 × 0.10 × 0.10 = 0.002 m³
• Bricks = 2.12 / 0.002 = 1060 bricks (approx.)
• With 10% Wastage = 1166 bricks

2. How Many Bricks in a 10x10 Wall?

10 ft × 10 ft = 100 sq ft. Same as above roughly 1160 bricks for a 9-inch thick wall.

3. How Many Square Feet Does 1000 Bricks Cover?

Reversing the formula:

• Brick Area with Mortar = (0.20 × 0.10) = 0.02 m² = 0.215 sq ft
• Total area = 1000 × 0.215 = 215 sq ft (approx.)

So, 1000 bricks can cover around 215 square feet (for a 4.5-inch wall thickness).
