How many bricks are in 1 cubic metre?

Using the Indian standard brick of 190×90×90 mm with a 10 mm mortar joint, about 500 bricks make up 1 cubic metre of brickwork.

How much cement and sand for brick mortar?

It depends on the mortar ratio and wall size. The mortar volume is the wall volume minus the brick volume, scaled by 1.33 for dry volume, then split by the cement:sand ratio. A 1:6 mix is common for general brickwork.

What is the standard brick size in India?

The Indian standard modular brick is 190×90×90 mm; with a 10 mm mortar joint it is treated as 200×100×100 mm for estimating.

How it's calculated

The wall volume is length × height × thickness. Each brick "occupies" its size plus a 10 mm mortar joint, so the brick count is the wall volume divided by that bricked-up size. The leftover space is mortar, scaled by 1.33 to dry volume and split by your cement:sand ratio.

Bricks = wall volume ÷ (brick + 10 mm joint). Mortar = wall volume − brick volume, then ×1.33, split by ratio.

Frequently asked questions

How many bricks in 1 m³?

About 500 standard Indian bricks (190×90×90 mm) with 10 mm joints.

Which mortar ratio?

1:6 is common for general brickwork, 1:4–1:5 for load-bearing or external walls.

Should I deduct doors and windows?

For a quick estimate the wastage covers minor openings; for large openings, reduce the wall area accordingly.
