Enter your wall size and get the full estimate: how many bricks to buy, the cement bags and sand for the mortar, and the brick cost in Rupees — using the standard Pakistani brick (9 × 4.5 × 3 inches) with a 10 mm mortar joint.
Standard Pakistani brick: 9 × 4.5 × 3 inches, laid with a 10 mm mortar joint — so each brick with mortar occupies about 0.0903 cubic feet, and about 831 bricks fill a 10 × 10 ft, 9-inch wall. The rate box uses Rs 18,000 per 1,000 as a starting point for Awwal (first-class) bricks — change it to your local kiln rate.

Bricks to buy include your wastage allowance. Mortar is calculated for the bricks actually in the wall (before wastage): cement in 50 kg bags, sand in cubic feet (cft). The brick cost uses your rate per 1,000 — labour and mortar materials are not priced here.
Standard 9 × 4.5 × 3 inch bricks, 10 mm mortar joints, 5% wastage included, no door/window deduction except where stated:
| Wall | Bricks Needed |
|---|---|
| 10 × 10 ft wall — 4.5 inch thick | 437 |
| 10 × 10 ft wall — 9 inch thick | 873 |
| Per 100 sq ft — 9 inch wall | 873 |
| 12 × 14 ft room — 4 walls, 10 ft high, 9 inch thick, minus 1 door + 1 window | 4,248 |
For a whole room, enter the total length of all walls (for example 52 ft for a 12 × 14 room) or use the "Same Walls" count for repeated walls.
Check it yourself: a 10 × 10 ft, 9-inch wall has a volume of 75 cft → 75 ÷ 0.0903 ≈ 831 bricks before wastage — the same figure published brick-calculation guides give for this wall.
For a 9-inch wall built with the standard 9 × 4.5 × 3 inch brick and 10 mm mortar joints, about 831 bricks before wastage — 873 with the usual 5% wastage added, which is what this calculator shows by default. A 4.5-inch partition wall needs about half as many: 437 for the same 100 square feet with wastage.
The standard kiln brick in Pakistan is 9 × 4.5 × 3 inches (about 225 × 113 × 75 mm), laid with a mortar joint of about 10 mm. This calculator uses exactly that size — if your bricks are a different size, your count will differ.
Awwal (first class) bricks are well-burnt, uniform in size and colour, with sharp edges and a clear metallic ring when two are struck together — they are used for main and load-bearing walls. Dom, also spelled Doem (second class), bricks are a little irregular or less evenly burnt and cost less; they are used where strength matters less. Below them comes the cheapest third-class (Khangar) brick.
Bricks are heavy and made in local kilns (bhatta), so the rate you pay depends on the kiln, fuel costs and how far the bricks travel. Market reports checked on 2 Nov 2026 put Awwal bricks roughly between Rs 16,000 and Rs 22,000 per 1,000 in different cities. That is why the rate in this calculator is an editable box — enter your own local rate for a true estimate.
Yes. The mortar estimate (cement bags and sand) is calculated from the actual mortar in the wall — wall volume minus the volume of the bricks — increased by the standard dry-volume factor of 1.30 and split by the mix ratio you choose. Wastage is separate: pick 0%, 5% or 10% (5% is the usual allowance for breakage and cutting).
