What is the standard brick size in Pakistan / India?

229 x 114 x 76 mm — or 9 x 4.5 x 3 inches if you talk to the kiln owner — is the standard fired-clay brick across Pakistan and most of India. The local terms are Awwal (first-class), Doyam (second-class), and Khingar (overburnt). India also uses Modular bricks (190 x 90 x 90 mm) in newer construction. Here is the thing nobody warns you about: catalogue size is the dry kiln size, but actual delivery shrinks 2 to 3 mm because clay shrinks as it bakes. Plan with the catalogue dimension and add 5 to 10 percent wastage to absorb the dimensional drift plus breakage and edge cuts.

How many bricks are in 1 cubic metre of wall?

Using Pakistan Standard bricks (229 x 114 x 76 mm) with a 10 mm mortar joint, you fit roughly 500 bricks per cubic meter of finished wall — each brick plus its share of mortar occupies about 0.002 cubic meters. US Modular bricks pack denser at ~825 per cubic meter because they are smaller. CMU 8-inch concrete blocks drop the count to ~70 per cubic meter — one block does the work of seven bricks. AAC blocks at 600 x 200 x 200 mm drop it further to ~42. Bigger unit, fewer pieces, faster construction.

How many bricks per square metre of wall?

Quick mental math for Pakistan: a half-brick (single-wythe) wall using standard 9-inch bricks needs about 55 bricks per square meter of wall face. A full-brick (double-wythe / 9-inch-deep) wall needs roughly 110 per square meter. US Modular: ~64 per m squared single-wythe. UK Engineering: ~58. CMU 8-inch block: only ~12. AAC 600 x 200 face: ~8. The calculator works out the exact number from your specific brick dimensions, joint thickness, and wall depth — but those benchmark numbers are useful when a contractor quotes you a brick count over the phone and you want to know if it sounds right.

How much cement and sand do I need for brickwork?

For a 1:6 cement-to-sand mortar — the default mix for non-load-bearing brick walls — every cubic meter of dry mortar uses roughly 0.143 cubic meters of cement (about 4 bags of 50 kg) and 0.857 cubic meters of sand (about 1,370 kg). The calculator already applies the 1.33 dry-volume factor for you. Wet mortar is what fills the joints in the finished wall. Dry materials are what you actually buy and stack on site. Most homeowners ordering for the first time confuse the two and either over-order or under-order — let the calculator do that conversion.

What is the 1.33 dry-volume factor in mortar calculation?

When you mix dry cement and sand with water, the wet mortar settles into a smaller volume than the loose dry materials added up to — water fills the voids and the whole mix consolidates. To get the dry materials you need to buy, you multiply the final wet-mortar volume by 1.33 (a 33 percent uplift). This is the standard CPWD / IS 2212 allowance used across South Asia and the calculator applies it automatically. Skip the factor and you will be 25 to 30 percent short on cement on delivery day.

Which mortar mix ratio should I use?

1:4 (rich mix, more cement) for load-bearing walls, foundation brickwork, and exposed walls that take monsoon weather directly. 1:6 (the default for almost everything else) for standard internal partitions, boundary walls, and most domestic construction — best strength-to-cost ratio. 1:8 (lean mix) for non-structural partitions or where lime is added for plasticity. Honest take: do not over-engineer with 1:4 because it feels safer. A 1:4 mortar shrinks and cracks more than 1:6 — you trade structural strength for visible hairline cracks. Use 1:6 unless an engineer specifically calls for 1:4.

How much wastage should I include?

5 percent for straight unbroken walls laid by an experienced raj (mason). 7 to 10 percent for walls with multiple openings, corners, or stepped features — which is most real plots. 12 to 15 percent for fair-face exposed brickwork where only flawless bricks go on the visible side and the rejects get pushed to the back. Add another 5 percent if your bricks arrive from multiple kiln batches with visible size variation — a common Pakistani reality when the local kiln owner mixes loads to fill an order.

Do clay bricks, concrete blocks, or AAC blocks need a different calculation?

The math is identical — wall volume divided by brick-plus-mortar volume, times the wastage factor. What changes wildly is the unit volume per piece. An AAC block at 600 x 200 x 200 mm has about 31 times the volume of one Pakistan Standard clay brick, so you need 31 times fewer pieces for the same wall. Switch the brick-type tabs in the calculator and you can compare clay versus CMU versus AAC instantly — useful when you are debating whether to use lighter AAC blocks on upper-storey partitions to reduce slab load.

How accurate is the 2D / 3D plot visualization?

The 2D top-down view solves the actual quadrilateral footprint from your four wall lengths — it anchors the west wall vertical and computes the other three to close the shape geometrically. It does not just average everything into a rectangle. If the four lengths cannot form a closed quadrilateral (which happens if one measurement is wrong or you typoed a side), it shows a warning instead of a misleading figure. The 3D isometric extrudes the same footprint upward by your wall height with the brick texture you picked, so you can visually sanity-check the proportions before ordering 6,000 bricks.

Should I use this for load-bearing wall design?

No, and please do not. This calculator gives material quantities only — bricks, mortar, cement, sand. Structural load-bearing wall design — thickness, reinforcement, foundation depth, lintel sizing — requires a registered structural engineer who reviews your soil report, the local seismic zone, and the live-load requirements. Use this tool to budget materials AFTER an engineer has confirmed the wall thickness and bond pattern. Saving the engineer's fee by guessing wall thickness is how Pakistani buildings end up with cracked load-bearing walls in year two.

How do I handle openings (doors and windows) accurately?

Open the 'Doors and windows' accordion. Enter the count of each plus the width and height. The calculator multiplies count by width by height by wall thickness and subtracts that opening volume from the gross wall volume before working out the brick count. For multiple different opening sizes (one front door at 3 by 7, two windows at 4 by 4, a back door at 2.5 by 7), either combine them into the two input slots by area, or just take the total opening square-footage manually — even rough opening deductions save a meaningful number of bricks on a typical plot.

Step-by-step calculation

Formula

Wall vol = (perimeter × thickness × height) − corner overlap. Bricks = ⌈net vol ÷ brick-with-mortar vol⌉ × (1 + waste %). Mortar dry = (wall vol − solid bricks) × 1.33.

1Perimeter = 47 ft 4.0 in + 52 ft 7.0 in + 60 ft + 58 ft 10.0 in = 66.67 m
2Gross wall vol = 66.67 × 0.229 × 3.048 − 4 × T² × H = 45.820 m³
3Subtract openings (doors + windows) = 1.126 m³ → net 44.695 m³
4Brick (with 10 mm joint) vol = 0.00234 m³
5Raw brick count = ⌈44.695 ÷ 0.00234⌉ = 19,075
6With 7% wastage = ⌈19075 × 1.07⌉ = 20,411 bricks
7Mortar wet = wall vol − (raw bricks × solid brick vol) = 6.849 m³
8Mortar dry = wet × 1.33 (shrinkage factor) = 9.109 m³
9Cement = 9.109 × (1/7) = 1.301 m³ ≈ 37.5 bags (50 kg)
10Sand = 9.109 × (6/7) = 7.808 m³ ≈ 12492 kg

Reference, not a substitute for a site quantity surveyor. Real-world brickwork varies by bond pattern, jointing skill, and brick consistency. Add a 10% wastage allowance for novice masons and re-measure on site after the first lift.

Formula

A typical 5-marla Pakistani house perimeter wall (~73 ft × 8 ft, 9-inch thick) needs about 3,000 Pakistan Standard bricks before wastage.

A 10-marla house full construction (foundation to roof) typically uses 35,000–55,000 Pakistan Standard bricks across boundary walls, partitions, and load-bearing walls.

1 cement bag (50 kg) lays approximately 100–120 standard bricks at a 1:6 mortar mix. A 1,000-brick wall therefore needs ~9–10 bags.

A few things worth knowing

If you are about to call the brick supplier with an order, here is the thing nobody tells you upfront: a Pakistani 9 x 4.5 x 3 inch brick is the catalogue size, not the size that arrives on your plot. Kiln-fired bricks shrink 2 to 3 mm during baking, and the local kiln owner mixes batches of slightly different sizes into one delivery. That dimensional drift, combined with edge cuts at corners, breakage during unloading, and the inevitable rejection of overburnt khingar bricks, means you always need 5 to 10 percent more than the raw math suggests. For a 4-wall plot — which is how most boundary walls are calculated — the second trap is corner overlap: adjacent walls share a column of bricks at each of the four corners, and counting them twice inflates your order by 3 to 5 percent. This calculator handles both, plus 22 different brick and block standards (Pakistan Standard, AAC blocks, CMU, US Modular, UK Engineering), plus the 1.33 dry-volume factor for mortar, plus cement bag count at 50 kg, plus sand weight. Honest take: order brick by truck-load (a standard truck holds ~5,000 bricks), get the cement and sand delivered separately the day before the raj starts, and keep 200 to 300 spare bricks for repairs and the inevitable mid-job design change.

Pro tips most people learn the hard way

In Pakistan, the standard fired-clay brick is roughly 9 x 4.5 x 3 inches, but the actual delivery is always 2 to 5 mm smaller because they shrink in the kiln. Always order based on the catalogue size and add 7 to 10 percent wastage — the missing dimension shows up as wider mortar gaps you have to fill, plus the breakage during transport.
Corner overlap is the silent over-order on 4-wall plots. Adjacent walls share a column of bricks at each corner — count them once, not twice. The calculator subtracts 4 x thickness squared x height automatically, but if you are estimating by hand you will inflate your order by 200 to 400 bricks on a typical 5 Marla plot.
1:6 cement-to-sand mortar is the default mix for boundary and partition walls. Use 1:4 only when an engineer specifies load-bearing or exposed monsoon-facing walls. Over-mixing with 1:4 sounds 'stronger' but actually causes more shrinkage cracks in the joints — you trade strength for visible hairline cracks at year two.
The 1.33 dry-volume factor is non-negotiable for cement and sand ordering. Wet mortar fills the joints; dry materials are what you buy. Skip the 33 percent uplift and you arrive at site 25 percent short on cement on the very first day of bricklaying.
A bricklayer (raj) in Pakistan lays 50 to 70 standard bricks per hour on clean wall stretches. Budget around 500 bricks per mason per day, not the 1,000 contractors sometimes quote — that figure assumes ideal conditions and no plumbing, electrical, or door-frame coordination on site.

?What is the Brick Calculator?

The Brick Calculator estimates the exact number of bricks required to build a wall or an entire 4-wall plot, plus the mortar volume, the cement bags, and the sand weight needed to lay them. Use Single Wall mode for a boundary wall or one parition; use Plot Mode to calculate four walls of potentially different lengths (north, south, east, west) — useful for room outlines, plot boundaries, or any rectangular/quadrilateral footprint where each side is a different length. All measurements accept feet+inches, metres, centimetres, millimetres, decimal feet, or inches per field, so you can mix and match units freely. The calculator picks from 22 international brick and block standards: clay bricks (Pakistan/India 9″×4½″×3″, India Modular 190×90×90 mm, US Modular and Standard, US Roman and Queen, UK Engineering 215×102.5×65 mm, Australian Standard 230×110×76 mm, Germany NF and DF, China 240×115×53 mm), concrete masonry units (CMU 4″/6″/8″ blocks 390×190 mm series, Pakistan 16″×8″ concrete blocks), and AAC / lightweight blocks (AAC 600×200×100/150/200 mm, Fly-Ash 230×110×70 mm). Custom dimensions are also supported. Output shows total brick count (with wastage), gross and net wall volume, mortar wet and dry volume (with the 1.33 industry shrinkage factor), 50-kg cement bag count, sand weight in kg, and per-wall breakdown when in Plot Mode. It deducts opening volumes (doors and windows) and corrects for corner overlap so corners aren't double-counted in plot mode. The 2D top-view and 3D isometric renderings update live so you can sanity-check the plot shape against your site measurements.

The Formula

Bricks = ⌈Net Wall Volume ÷ (Brick + Mortar Joint Volume)⌉ × (1 + Wastage%). Mortar (dry) = (Wall Volume − Solid Bricks Volume) × 1.33. Cement = Mortar Dry ÷ (1 + ratio); Sand = Mortar Dry × ratio ÷ (1 + ratio).

Step 1 — Wall volume: For a single wall, V = Length × Height × Thickness. For a 4-wall plot, V = (Perimeter × Thickness × Height) − 4 × T² × H to subtract the corner overlap where adjacent walls share a column of bricks. Step 2 — Net volume: Subtract the volume of every door and window (count × width × height × wall thickness). This step prevents over-ordering on plots with many openings. Step 3 — Brick unit volume: A laid brick occupies its own size PLUS one mortar joint on its length and height edges. Effective unit = (L+m) × W × (H+m), where m is the mortar thickness (typically 10 mm). The width is unchanged because that's the wall-thickness direction. Step 4 — Brick count: Divide net wall volume by effective unit volume and round up. Multiply by (1 + waste%) where 5–10% is industry standard for clean walls. Step 5 — Mortar volume: Subtract the solid-brick volume from the net wall volume. This is the WET mortar volume. Multiply by 1.33 to get the DRY volume needed when buying cement and sand (the dry-volume factor accounts for mortar shrinkage when water is added). Step 6 — Cement and sand split: For a 1:N mix ratio (cement:sand), cement volume = mortar dry ÷ (1+N) and sand volume = mortar dry × N ÷ (1+N). Convert cement m³ to 50-kg bags by dividing by ≈0.0347 m³ per bag (1440 kg/m³ density). Sand kg = sand m³ × 1600 kg/m³.

Put It in Perspective

A typical 5-marla Pakistani house perimeter wall (~73 ft × 8 ft, 9-inch thick) needs about 3,000 Pakistan Standard bricks before wastage.

A 10-marla house full construction (foundation to roof) typically uses 35,000–55,000 Pakistan Standard bricks across boundary walls, partitions, and load-bearing walls.

1 cement bag (50 kg) lays approximately 100–120 standard bricks at a 1:6 mortar mix. A 1,000-brick wall therefore needs ~9–10 bags.

A truck of standard bricks holds ~5,000 pieces. A 5-marla house exterior wall fits in 1 truck; a full house build needs 7–10 trucks.

Bricklaying speed: a single mason lays 50–70 standard bricks/hour on a clean stretch — so 500 bricks/day per mason is a reasonable budget, not 1,000.

Switching from clay brick to AAC block on a 50 m² wall reduces the unit count from ~2,750 to ~400 and the wall weight from ~9.6 tonnes to ~3 tonnes — useful for upper-storey internal partitions.

Practical Examples

A 5 × 3 × 0.23 m single-brick wall using Pakistan Standard bricks (229×114×76 mm) with 10 mm joint and 7% waste needs ~530 bricks, ~0.83 m³ of dry mortar, ~3.4 cement bags (1:6 mix), and ~640 kg of sand.

A plot with N=47'4", S=52'7", E=60', W=58'10" walls at 10' height and 9" thickness uses ~6,800 Pakistan Standard bricks, ~10.5 m³ dry mortar, ~43 cement bags, and ~8 tonnes of sand.

Switching from Pakistan Standard to AAC 600×200×200 mm blocks for the same plot drops the unit count from ~6,800 to ~700 because each AAC block is ~10× the volume of a clay brick.

Adding 1 door (3'×7') and 2 windows (4'×4') to a 4-wall plot subtracts ~2.0 m³ of opening volume, saving ~330 standard bricks before waste.

A 100-foot-long × 8-foot-high boundary wall at single-brick thickness with 10% waste plans for ~4,200 standard bricks, ~6.4 m³ dry mortar, ~26 cement bags (1:6) and ~4.9 tonnes of sand.

Using a 1:4 (rich) mortar instead of 1:6 (standard) raises the cement bag count by ~40% on the same wall — useful for load-bearing walls but unnecessary for boundary walls.

A 5 Marla (~125 sq yd) plot perimeter of ~73 ft at 8 ft height with 9-inch walls needs ~3,000 Pakistan Standard bricks for the perimeter wall.

Hourly bricklayer output is roughly 50–70 bricks/hour for clean wall stretches; budget proportionally for labour days from this calculator's output.

Frequently Asked Questions

Switch to Plot Mode. Enter the four wall lengths separately — north, south, east, west — they almost never match exactly on a real Pakistani plot, and that is fine. Enter the wall height and the thickness (9-inch single-brick is standard for boundary walls). The calculator works out the perimeter, subtracts the four corner overlaps (because adjacent walls share a column of bricks at each corner — counting them twice is the most common manual-estimation mistake), deducts any door and window openings, and divides by the brick-plus-mortar volume to give you the count. The 2D top-view shows the actual quadrilateral shape so you can sanity-check it against your plot before placing the order.

Bricks = ⌈Net Wall Volume ÷ (Brick + Mortar Joint Volume)⌉ × (1 + Wastage%). Mortar (dry) = (Wall Volume − Solid Bricks Volume) × 1.33. Cement = Mortar Dry ÷ (1 + ratio); Sand = Mortar Dry × ratio ÷ (1 + ratio).

A typical 5-marla Pakistani house perimeter wall (~73 ft × 8 ft, 9-inch thick) needs about 3,000 Pakistan Standard bricks before wastage.

A 10-marla house full construction (foundation to roof) typically uses 35,000–55,000 Pakistan Standard bricks across boundary walls, partitions, and load-bearing walls.

1 cement bag (50 kg) lays approximately 100–120 standard bricks at a 1:6 mortar mix. A 1,000-brick wall therefore needs ~9–10 bags.

A few things worth knowing

Pro tips most people learn the hard way

In Pakistan, the standard fired-clay brick is roughly 9 x 4.5 x 3 inches, but the actual delivery is always 2 to 5 mm smaller because they shrink in the kiln. Always order based on the catalogue size and add 7 to 10 percent wastage — the missing dimension shows up as wider mortar gaps you have to fill, plus the breakage during transport.
Corner overlap is the silent over-order on 4-wall plots. Adjacent walls share a column of bricks at each corner — count them once, not twice. The calculator subtracts 4 x thickness squared x height automatically, but if you are estimating by hand you will inflate your order by 200 to 400 bricks on a typical 5 Marla plot.
1:6 cement-to-sand mortar is the default mix for boundary and partition walls. Use 1:4 only when an engineer specifies load-bearing or exposed monsoon-facing walls. Over-mixing with 1:4 sounds 'stronger' but actually causes more shrinkage cracks in the joints — you trade strength for visible hairline cracks at year two.
The 1.33 dry-volume factor is non-negotiable for cement and sand ordering. Wet mortar fills the joints; dry materials are what you buy. Skip the 33 percent uplift and you arrive at site 25 percent short on cement on the very first day of bricklaying.
A bricklayer (raj) in Pakistan lays 50 to 70 standard bricks per hour on clean wall stretches. Budget around 500 bricks per mason per day, not the 1,000 contractors sometimes quote — that figure assumes ideal conditions and no plumbing, electrical, or door-frame coordination on site.

Put It in Perspective

A typical 5-marla Pakistani house perimeter wall (~73 ft × 8 ft, 9-inch thick) needs about 3,000 Pakistan Standard bricks before wastage.

A 10-marla house full construction (foundation to roof) typically uses 35,000–55,000 Pakistan Standard bricks across boundary walls, partitions, and load-bearing walls.

1 cement bag (50 kg) lays approximately 100–120 standard bricks at a 1:6 mortar mix. A 1,000-brick wall therefore needs ~9–10 bags.

A truck of standard bricks holds ~5,000 pieces. A 5-marla house exterior wall fits in 1 truck; a full house build needs 7–10 trucks.

Bricklaying speed: a single mason lays 50–70 standard bricks/hour on a clean stretch — so 500 bricks/day per mason is a reasonable budget, not 1,000.

Switching from clay brick to AAC block on a 50 m² wall reduces the unit count from ~2,750 to ~400 and the wall weight from ~9.6 tonnes to ~3 tonnes — useful for upper-storey internal partitions.

Practical Examples

A plot with N=47'4", S=52'7", E=60', W=58'10" walls at 10' height and 9" thickness uses ~6,800 Pakistan Standard bricks, ~10.5 m³ dry mortar, ~43 cement bags, and ~8 tonnes of sand.

Switching from Pakistan Standard to AAC 600×200×200 mm blocks for the same plot drops the unit count from ~6,800 to ~700 because each AAC block is ~10× the volume of a clay brick.

Adding 1 door (3'×7') and 2 windows (4'×4') to a 4-wall plot subtracts ~2.0 m³ of opening volume, saving ~330 standard bricks before waste.

A 100-foot-long × 8-foot-high boundary wall at single-brick thickness with 10% waste plans for ~4,200 standard bricks, ~6.4 m³ dry mortar, ~26 cement bags (1:6) and ~4.9 tonnes of sand.

Using a 1:4 (rich) mortar instead of 1:6 (standard) raises the cement bag count by ~40% on the same wall — useful for load-bearing walls but unnecessary for boundary walls.

A 5 Marla (~125 sq yd) plot perimeter of ~73 ft at 8 ft height with 9-inch walls needs ~3,000 Pakistan Standard bricks for the perimeter wall.

Hourly bricklayer output is roughly 50–70 bricks/hour for clean wall stretches; budget proportionally for labour days from this calculator's output.
