Brick Calculator - Calculate Number of Bricks & Blocks
Calculate the number of bricks needed for a wall based on wall dimensions, brick size, mortar joint thickness, and wastage factor. Construction calculator for civil engineering and masonry projects. Supports standard Indonesian brick sizes and cement-sand mortar ratios.
Brick Requirement Formula
Number of Bricks = Wall Area × Consumption per m²Variables:
- Wall AreaLength × Height of wall (m²)Length × Height of wall (m²)(e.g.: 12 m²)
- Consumption/m²Number of standard bricks per square meterNumber of standard bricks per square meter(e.g.: 70 pieces for red brick)

Examples
House Wall Example
Problem:
Wall 4m long and 3m high using red brick.
Solution:
- 1.Area = 4 × 3 = 12 m²
- 2.Requirement = 12 × 70 (standard assumption)
- 3.Total = 840 bricks
Result:840 bricks
You need about 840 red bricks for that wall.
Frequently Asked Questions
How many red bricks per m²?
Generally, about 70–75 red bricks are needed per 1 square meter of wall.
What about lightweight blocks (hebel)?
For standard hebel size (60×20×10 cm), about 8.3 blocks are needed per m².
