Why Brick Calculation Matters

Ordering the right number of bricks saves money, prevents delays, and ensures your project goes smoothly. Too few bricks and you're stuck waiting; too many and you've wasted money on unused materials.

Step 1: Understand Brick Dimensions

Standard brick sizes vary by region:

US Standard Bricks

- Modular: 3 5/8" × 2 1/4" × 7 5/8"

- Queen: 3 1/8" × 2 3/4" × 7 5/8"

- King: 2 3/4" × 2 5/8" × 9 5/8"

Metric Bricks

- Standard: 215mm × 102.5mm × 65mm

Step 2: Calculate Brick Coverage

Formula for Single Brick Area

``

Brick Coverage = (Brick Height + Mortar Joint) × (Brick Length + Mortar Joint)

``

Standard mortar joints: 3/8" (10mm)

Bricks per Square Foot

Modular bricks with 3/8" joints: ~7 bricks per sq ft

Our [Brick Calculator](/brick-calculator) does all this math for you automatically.

Step 3: Calculate Your Project Area

1. Measure wall height and length

2. Multiply for total area

3. Subtract openings (doors, windows)

4. Multiply by bricks per sq ft
