Brick Calculator – Estimate the Number of Bricks Needed
This Brick Calculator helps you accurately estimate the number of bricks required to build walls, fences, or any masonry structure. Based on your wall dimensions and chosen brick size, this tool calculates how many standard, modular, or custom bricks you'll need — including mortar gaps and wastage.
How to Use the Brick Calculator
Enter the total length and height of the wall, the size of one brick (length, width, height), and the thickness of the mortar gap. Choose single or double wall construction. The result will include:
- Total number of bricks needed
- Wall area covered
- Volume and wastage buffer
Brick Calculation Formula
Total Bricks = (Wall Area ÷ Brick Area) × Wall Thickness Multiplier
Example (single wall):
If wall is 10ft × 10ft and brick size is 8"×2.25"×3.75", mortar gap 0.5", you can expect ~511 bricks for a single wall, excluding 5–10% wastage.
Common Brick Sizes (US Standard)
| Type | Dimensions (inches) | Bricks/sq ft |
|---|---|---|
| Modular | 7.5 × 2.25 × 3.5 | 6.8 |
| Standard | 8 × 2.25 × 3.75 | 6.5 |
| Queen | 7.75 × 2.75 × 2.75 | 5.8 |
Where Can You Use This Calculator?
- Brick wall construction (interior & exterior)
- Boundary wall & compound fencing
- Fireplace, garden bed, or brick patio
- House façade and architectural accents
Frequently Asked Questions (FAQs)
How many bricks are in 100 sq ft?
Depending on brick size and mortar thickness, around 650–700 modular bricks are needed per 100 sq ft of wall.
How much mortar is needed per brick?
On average, mortar accounts for 20% of the wall volume. This calculator includes mortar spacing in its estimates.
How much wastage should I account for?
Add 5–10% extra bricks to account for breakage, cuts, and site wastage.
Can I use this calculator for a double wall?
Yes, select "Double Wall" option to double the volume. Useful for structural or insulation walls.
What if I'm using custom-sized bricks?
You can enter any custom brick dimensions (in inches or cm) for precise calculations.
