दीवार में कितनी ईंट लगेगी — Brick Calculation Formula

Construction शुरू करने से पहले exact brick quantity calculate करना ज़रूरी है। ज़्यादा order करो तो पैसा waste, कम करो तो काम रुक जाता है। यह guide simple formulas देती है।

Standard Brick Size (India)

- Length: 9 inch (228 mm) - Width: 4.5 inch (114 mm) - Height: 3 inch (76 mm) - Mortar joint: 0.5 inch (10 mm)

Brick with mortar: 9.5 × 5 × 3.5 inch

Formula: Bricks Per Square Foot

4.5 inch wall (Half brick): Bricks per sq ft = 144 / (9.5 × 3.5) = 4.33 ≈ 5 bricks (with wastage)

9 inch wall (Full brick): Bricks per sq ft = 144 × 2 / (9.5 × 3.5) = 8.66 ≈ 10 bricks (with wastage)

13.5 inch wall (One and half brick): Bricks per sq ft = 144 × 3 / (9.5 × 3.5) = 12.99 ≈ 15 bricks (with wastage)

Quick Reference Table

Room Example — 10 × 12 ft Room

Walls: - 2 walls of 10 ft × 10 ft = 200 sq ft - 2 walls of 12 ft × 10 ft = 240 sq ft - Total wall area = 440 sq ft

Minus openings: - 1 door (3 × 7 ft) = 21 sq ft - 2 windows (4 × 4 ft each) = 32 sq ft - Net wall area = 440 - 21 - 32 = 387 sq ft

Bricks needed (9 inch wall): 387 × 10 = 3,870 bricks Add 5% wastage = ~4,064 bricks

Full House Calculation — 1000 sq ft

Note: This is conservative. Many homes need 40,000-50,000 bricks for better specification.

Pro Tips
