Formula Reference

Brick Calculation Formula — All Methods

Bricks = Wall Volume ÷ Volume of One Brick (with mortar)

Step 1 — Wall Volume (CFT): Length (ft) × Height (ft) × Thickness (ft)
Step 2 — Brick Volume with mortar (CFT): (9.5 × 5 × 3.5) ÷ 1728 = 0.096 CFT
Step 3 — Net Bricks: Wall Volume ÷ 0.096
Step 4 — Add Wastage (5%): Net Bricks × 1.05
9 inch wall formula: Bricks/sq ft = 1/(brick vol in sq ft) ≈ 10–12 bricks per sq ft
Pakistan standard: 9×4.5×2.75 inch brick ≈ 475–500 bricks per m³

How To Use

Step-by-Step: Brick Calculation Formula

Select Calculation Method

Choose “By Wall Dimensions” if you know length, height, and thickness. Choose “By Area” if you have sq ft or sq m of wall area. Choose “By Volume” if you have cubic feet or cubic meters directly.

Enter Wall Dimensions

Enter length and height in feet or meters. Select wall thickness — 9 inch (most common in India), 4.5 inch (half brick), 12 inch, or custom. The 9 inch brick wall calculation is the default standard.

Select Brick Standard

Choose Indian standard (9×4.5×3″), Pakistan standard (9×4.5×2.75″), Modular, US, or custom size. The brick calculation formula in Pakistan uses slightly thinner bricks, giving higher brick count per volume.

Get Complete Estimate

Instantly see total bricks with wastage, net bricks without wastage, volume in CFT, and equivalent brass — ready for procurement and budgeting. Add 5% wastage for standard work, 10% for complex patterns.

FAQ

Brick Calculation Formula — People Also Ask

What is the brick calculation formula for a wall?

Brick Calculation Formula for wall: (1) Find wall volume = L × H × T in feet. (2) Find brick volume with mortar = (9.5×5×3.5) ÷ 1728 = 0.0961 CFT for standard Indian brick with 0.5″ mortar. (3) Number of bricks = Wall Volume ÷ 0.0961. (4) Add 5% wastage. Example: 20ft × 10ft × 0.75ft wall = 150 CFT ÷ 0.0961 = 1561 bricks + 5% = 1639 bricks total.

How many bricks in a 9 inch wall per sq ft?

For a 9 inch thick wall using standard Indian bricks (9×4.5×3 inch with 0.5″ mortar): approximately 10.8 bricks per sq ft of wall face area. So for 100 sq ft of 9 inch wall: 100 × 10.8 = 1080 bricks (net). Add 5% wastage = 1134 bricks total. Our 9 inch brick wall calculation tool handles this automatically.

What is the brick calculation formula in Pakistan?

Pakistan uses slightly thinner bricks: 9×4.5×2.75 inches (vs India’s 3-inch height). With 0.5″ mortar: brick volume = 9.5×5×3.25 ÷ 1728 = 0.0895 CFT. So bricks per CFT = 1 ÷ 0.0895 = 11.2 bricks/CFT. For a standard room in Pakistan: approximately 450–500 bricks per cubic meter of wall. Select “Pakistan Standard” in our brick calculator for accurate results.

How to calculate bricks in square feet?

Brick calculator square feet formula: Bricks = (Wall Area in sq ft × Wall Thickness in ft) ÷ Brick Volume in CFT. For a 4.5-inch (half brick) wall: Bricks per sq ft = 0.375 ÷ 0.0961 = 3.9 bricks/sq ft. For 9-inch wall: 0.75 ÷ 0.0961 = 7.8 bricks per sq ft (without mortar waste). Use our “By Area” mode for direct sq ft input.

How to use brick calculation formula in Excel?

Excel formula for bricks: =ROUNDUP((L*H*T)/(((BL+M)*(BW+M)*(BH+M))/1728)*(1+Wastage/100),0). Where L,H,T = wall length, height, thickness in feet; BL,BW,BH = brick dimensions in inches; M = mortar thickness in inches. Our online calculator does this automatically — just enter values and get results without building any spreadsheet.
