Standards Cited
- ASTM C216 — Standard Specification for Facing Brick (Solid Masonry Units Made from Clay or Shale)
Defines standard US modular brick dimensions (194 x 92 x 57mm) used in the calculator - TMS 402/602 — Building Code Requirements and Specification for Masonry Structures

Formulas Used
- Wall area:
wallArea = wallLength x wallHeight
Source: Basic geometry - Net wall area:
netWallArea = wallArea - openingArea
Source: Standard deduction method - Bricks required:
bricksRequired = ceil(netWallArea x bricksPerM2 x (1 + wastage/100))
Source: ASTM C216 / TMS 402/602 — Bricks per m2: stretcher bond = 60, English/Flemish/header bond = 120
Key Assumptions
- US modular brick size: 194 x 92 x 57mm (7-5/8 x 3-5/8 x 2-1/4 in) — ASTM C216
- Default mortar joint width: 10mm (3/8 in) — TMS 402/602
- Running/common/stack bond uses ~74 bricks per m2; flemish bond uses ~111 bricks per m2 — BIA Technical Note 10
- Typical wastage allowance of 5-10% for cutting and breakage — Industry standard practice
