A Free Tools Brick Calculator is an online construction tool that helps builders, homeowners, contractors, architects, and DIY enthusiasts estimate the number of bricks, mortar, and material costs required for a wall or masonry project. Instead of calculating everything manually, the calculator provides fast and accurate estimates based on your project dimensions.
Whether you’re building a garden wall, house exterior, retaining wall, fireplace, garage, or commercial building, a brick calculator saves time, reduces waste, and helps create a more accurate budget.
How a Brick Calculator Works
A brick calculator typically requires several basic measurements:
- Wall length
- Wall height
- Wall thickness
- Brick dimensions
- Mortar joint thickness
- Number of openings (doors and windows)
- Waste percentage (usually 5–10%)
After entering the measurements, the calculator estimates:
- Total wall area
- Total wall volume
- Number of bricks required
- Mortar volume
- Estimated material cost
- Waste allowance
Basic Formula
Step 1: Calculate Wall Area
Wall Area = Length × Height
Example:
- Length = 30 ft
- Height = 8 ft
30 × 8 = 240 sq ft
Step 2: Calculate Brick Face Area
Example brick:
8 in × 2.25 in
Convert to feet:
0.667 × 0.188 = 0.125 sq ft
Step 3: Estimate Bricks Needed
Bricks = Wall Area ÷ Brick Face Area
Or use standard brick coverage values.
Standard Brick Coverage
Approximate bricks needed per square foot:
| Brick Type | Bricks per sq ft |
|---|---|
| Modular Brick | 6.75 |
| Queen Brick | 5.5 |
| Engineer Brick | 6.5 |
| Standard Clay Brick | 7 |
These values include mortar joints.
Example Calculation
Wall:
- Width: 25 ft
- Height: 10 ft
Wall Area
25 × 10 = 250 sq ft
Using modular bricks:
250 × 6.75
= 1,688 bricks
Add 5% waste:
1,688 × 1.05
≈ 1,772 bricks
Mortar Estimation
A brick calculator also estimates mortar.
Average mortar requirement:
- About 1 cubic yard of mortar for every 1,000 standard bricks.
Example:
2,000 bricks
≈ 2 cubic yards of mortar
Cost Estimation
Example:
Brick cost:
$0.80 each
Required:
1,772 bricks
Brick cost:
1,772 × $0.80
= $1,417.60
Mortar:
$180
Delivery:
$150
Total:
$1,747.60

Frequently Asked Questions
Is a Brick Calculator accurate?
Yes, it provides reliable estimates when you enter accurate measurements. Actual usage may vary slightly depending on cutting, bond pattern, and workmanship.
Does it include mortar?
Many brick calculators estimate both the number of bricks and the volume of mortar required.
Can it calculate costs?
Yes. Many calculators allow you to enter the price per brick, mortar costs, and other expenses to estimate the total project cost.
Can it handle metric and imperial units?
Most modern brick calculators support both measurement systems and automatically convert between them.
Why should I add extra bricks?
A waste allowance helps account for broken bricks, cuts, installation errors, and spare bricks for future maintenance.
