What is a Bricks Per Square Foot Calculator?

The Bricks Per Square Foot Calculator helps you determine how many bricks are required to cover a given wall area based on the size of each brick. This is a valuable tool for contractors, masons, and DIY home builders to plan and purchase the right number of bricks for construction projects.

It also optionally accounts for mortar gap thickness, which slightly increases the spacing between bricks.

Formulas Used

1. Brick Area (with mortar)

$\text{Brick Area (sq in)} = (\text{Brick Length} + \text{Mortar Gap}) \times (\text{Brick Width} + \text{Mortar Gap})$

2. Bricks per Square Foot

$\text{Bricks per Sq Ft} = \frac{144}{\text{Brick Area (sq in)}}$

(Since 1 sq ft = 144 sq inches)

3. Total Bricks Required

$\text{Total Bricks} = \text{Wall Area (sq ft)} \times \text{Bricks per Sq Ft}$

Example Calculation

Let’s say:

Wall Area = 100 sq ft
Brick Length = 8 inches
Brick Width = 2.5 inches
Mortar Gap = 0.5 inches

Step 1: Calculate Brick Area (with mortar)

$\text{Brick Area} = (8 + 0.5) \times (2.5 + 0.5) = 8.5 \times 3 = 25.5$

Step 2: Bricks per Square Foot

$\text{Bricks per Sq Ft} = \frac{144}{25.5} \approx 5.65$

Step 3: Total Bricks Required

$\text{Total Bricks} = 100 \times 5.65 = 565$

Final Output:

Bricks per Square Foot: 5.65
Total Bricks Required: 565

Conclusion

A Bricks Per Square Foot Calculator is an essential tool for planning construction projects. Whether you're building a wall, boundary, or pavement, it ensures accurate material estimation — saving time, money, and effort.
