Brick Calculator India 2026 Accurate
Plan your construction with precision. Get brick quantity, cement bags, and sand for 9-inch & 4.5-inch brick walls using Indian standard brick size (190×90×90 mm). Updated for 2026, including wastage and mortar ratio.
Brick, Cement & Sand Calculator
Estimates based on Indian standard brick (190×90×90 mm) + 10mm mortar → effective 200×100×100 mm. Cement calculated for 1:6 mix (dry volume factor 1.33). Wastage applied on bricks.
How to Calculate Bricks for a Wall: Step-by-Step Formula
Whether you are planning a boundary wall, a partition, or a full house, knowing the brick calculation formula saves material cost and avoids waste. In India, the most common brick size is 190 mm × 90 mm × 90 mm. With a 10 mm mortar joint, the modular size becomes 200 mm × 100 mm × 100 mm. Our brick calculator uses this standard to give you precise numbers for 9 inch brick wall calculation and 4.5 inch brick wall calculation. Follow these professional steps for manual check:
- Step 1: Measure wall length & height (in feet/meters). Compute gross wall area (length × height).
- Step 2: Deduct openings (door/window area) to get net brickwork area.
- Step 3: Multiply net area by wall thickness (0.75 ft for 9-inch, 0.375 ft for 4.5-inch) → volume of wall in cubic ft.
- Step 4: Convert volume to cubic meters (1 m³ = 35.315 ft³) or use brick volume with mortar: 0.2 × 0.1 × 0.1 = 0.002 m³ per brick.
- Step 5: Number of bricks = wall volume (m³) / 0.002. Add 5–10% wastage for breakage.
- Step 6: Calculate mortar volume = total wall volume – (actual brick volume × number of bricks). Then compute cement & sand using ratio 1:6.
Brick Quantity per 100 Sq.ft (Approx) – India Standard
| Wall Type | Bricks per 100 sq.ft (without openings) | Cement bags (approx) | Sand (cft) |
|---|---|---|---|
| 4.5-inch (half brick) | 500–520 bricks | 4.2–4.8 bags | 18–22 cft |
| 9-inch (full brick) | 1000–1040 bricks | 8.5–9.5 bags | 38–44 cft |
*Values vary with mortar thickness & wastage. Always use our dynamic calculator for exact dimensions.
Exclusive Pro Tips: Accurate Brick Work Calculation for 2026
- Check brick quality: Use first-class burnt clay bricks with uniform size. Variation >3mm affects count.
- Mortar ratio choice: For load-bearing walls use 1:6 (cement:sand); for plaster and non-structural 1:8 is also used but our calculator sticks to 1:6/1:4.
- Wastage wisdom: Add 5–8% for standard projects, up to 10% if irregular cutting required. Our tool applies wastage directly.
- Openings deduction: Always subtract door/window area to avoid over-ordering bricks by up to 15%.
- 9-inch vs 4.5-inch: 9-inch walls are structural, provide strength and insulation; 4.5-inch are for partition and non-load bearing walls.
Brick Calculation for Different Scenarios
Whether you need how to calculate bricks for a 10×10 room or estimate material for a compound wall, our brick calculator India handles all. For 1 cubic meter brick work (1m³), the approximate brick count is 500 bricks including mortar. Similarly, for a 9-inch wall, you need roughly 12–13 bricks per square foot. Use this guide alongside the interactive tool to cross-check:
- 1 sqm 9-inch wall: ~130 bricks (including 10mm mortar).
- 1 sqm 4.5-inch wall: ~65 bricks.
- Brick cement sand calculator: For 1000 bricks, cement ≈ 6–7 bags (1:6 ratio) and sand ≈ 30–35 cft.
Our calculator also provides mortar volume in m³, crucial for ordering ready-mix or site mixing. Updated for 2026 construction trends — we follow IS 2212 (Brickwork Code) and current market practices.

Frequently Asked Questions – Brick Calculation
Indian standard brick size is 190 mm × 90 mm × 90 mm. With 10 mm mortar, the modular size becomes 200×100×100 mm, used in most brick calculators.
Approximately 1,000 to 1,040 bricks, depending on mortar thickness and wastage. Use our 9 inch wall brick calculator for exact figures.
First find mortar volume (wall volume minus total brick volume). Multiply dry volume factor (1.33) then apply mix ratio (e.g., 1:6). Our brick cement calculator does this instantly.
Yes, select wall thickness dropdown – our tool automatically adjusts thickness and shows bricks, cement, sand for both cases.
Absolutely, you can enter openings (door/window area in sq.ft) and set custom wastage percentage. It gives you net required bricks and material.
For 1 m³ brickwork (1:6 mortar), about 0.3 m³ of wet mortar → dry volume ~0.4 m³ → cement approx 1.5 bags (75 kg) and sand ~0.34 m³ (12 cft).
