Brick Calculator - Calculate Bricks, Mortar & Cost
Professional brick calculator tool for construction projects. Calculate the exact number of bricks needed, mortar quantity, and total cost for your wall construction project. Get accurate results instantly with our free, mobile-friendly calculator.
How to Use the Brick Calculator
Step 1: Enter Wall Dimensions
Input the length, height, and thickness of your wall. You can choose from standard thickness options or enter a custom value.
Step 2: Select Brick Size
Choose from common brick sizes like Standard, Modular, King, or Queen bricks. For custom sizes, select "Custom size" and enter dimensions.
Step 3: Set Mortar Specifications
Enter the mortar joint thickness (typically 8-12mm) and wastage percentage (usually 3-10% for breakage and cutting).
Step 4: Add Pricing (Optional)
Enter brick and mortar prices to calculate the total cost of your project materials.
Step 5: Calculate
Click the "Calculate" button to get detailed results including number of bricks, mortar volume, and total cost.
Formula Used
Number of Bricks Calculation
Basic Formula:
Number of bricks = (Wall Area / Brick Area) × (1 + Wastage%)
Where:
- Wall Area = Length × Height
- Brick Area = (Brick Length + Mortar Thickness) × (Brick Height + Mortar Thickness)
- Wastage is typically 3-10% for breakage and cutting
Mortar Volume Calculation
Formula:
Mortar Volume = Wall Volume - (Number of bricks × Brick Volume)
Simplified:
Mortar Volume ≈ Wall Volume × 0.25 to 0.30 (25-30% of wall volume)

Calculation Examples
Example 1: Standard Residential Wall
Given:
- Wall: 10m × 3m (single brick thickness)
- Standard bricks: 230×110×76mm
- Mortar thickness: 10mm
- Wastage: 5%
Calculation:
- Wall area: 10 × 3 = 30 m²
- Brick area (including mortar): 0.24 × 0.086 = 0.02064 m²
- Bricks needed: 30 / 0.02064 = 1,453 bricks
- With wastage: 1,453 × 1.05 = 1,526 bricks
Example 2: Garden Wall
Given:
- Wall: 5m × 1.5m (single brick thickness)
- Modular bricks: 194×92×57mm
- Mortar thickness: 8mm
- Wastage: 8%
Result:
- Approximately 432 bricks needed
- Mortar volume: ~0.19 m³
- About 8 bags of mortar required

Frequently Asked Questions
How many bricks do I need for a wall?
The number of bricks needed depends on the wall dimensions, brick size, and mortar thickness. Our calculator uses the formula: Number of bricks = (Wall area / Brick area) × (1 + wastage factor). For a standard 10m × 3m wall using standard bricks, you'll need approximately 1,500-1,600 bricks including wastage.
How do you calculate mortar for bricks?
Mortar volume is calculated based on the joints between bricks. The formula considers horizontal and vertical mortar joints, typically requiring 25-30% of the total brick volume in mortar. Our calculator accounts for mortar thickness and provides volume in cubic meters and number of bags needed.
What is the standard brick size?
Standard brick sizes vary by region. Common sizes include: Standard (230×110×76mm), Modular (194×92×57mm), King (194×92×70mm), and Queen (194×92×70mm). Our calculator supports all these sizes plus custom dimensions.
What wastage percentage should I use?
Typical wastage ranges from 3-10% depending on the project complexity and worker skill level. For simple straight walls, use 3-5%. For complex layouts with many cuts and corners, use 8-10%. Our calculator defaults to 5% but allows customization.
How thick should mortar joints be?
Standard mortar joint thickness ranges from 8-12mm. Most construction uses 10mm joints. Thicker joints (12mm+) are used for irregular bricks or aesthetic purposes, while thinner joints (8mm) are used for precise work with high-quality bricks.
Can I use this calculator for different wall thicknesses?
Yes, our calculator supports both single brick (110mm) and double brick (230mm) walls, as well as custom thicknesses. The wall thickness affects the total volume but not the face area calculation for brick count.
