Every input includes a simple explanation.

Wall lengthThe end-to-end measurement of the wall, room, slab, bar, or surface.

Wall heightThe bottom-to-top measurement of the wall or room.

Wall thicknessThe side-to-side wall width or the planned layer thickness.

Opening areaThe combined area of doors, windows, or other gaps to subtract.

m²

Brick lengthThe longest side of one brick, without the mortar joint.

Brick widthThe side-to-side thickness of one brick, without the mortar joint.

Brick heightThe top-to-bottom size of one brick, without the mortar joint.

Mortar jointThe planned thickness of mortar between neighbouring bricks.

Mortar sand ratio (cement = 1)The sand amount compared with one equal part of cement.

parts

Mortar dry-volume factorThe extra dry material needed to make the required wet mix volume.

Brick wastageExtra material added for cuts, breakage, spillage, or small site differences.

Your result

Bricks to order

1,231 bricks

Purchase quantities are rounded up; site bonding, cuts and workmanship can change consumption.

Cement2.9 bags (round up to 3)

Sand0.6 m³

Wet mortar0.53 m³

Use this for preliminary quantity estimation only. Final structural design, reinforcement and safety decisions must be made by a qualified civil or structural engineer.

How this was calculated

Formula used

Brick modules determine count; dry mortar is divided by the entered cement:sand ratio

Your values in the formula

2.3 m³ ÷ 0.002 m³/module × wastage = 1,231 bricks

Assumptions and rounding

Cement density 1,440 kg/m³ and 50 kg bags are editable constants in methodology.
Dry-volume factor is an estimate.

This is an early quantity estimate. Site conditions, drawings, product details and workmanship can change the final requirement.

How to use this calculator

Use a real value. Check an appliance label, bill, site measurement, product sheet or official record.
Replace the examples. Example values show how the tool works; they do not describe every home.
Check the working. Open “How this was calculated” to see the formula, your values, losses and rounding.
Verify before you act. Use the result for learning and early planning, then check the important decision where shown.

What can change the answer

Check these details

Real site dimensions and workmanship affect the quantity.

Transport, cutting, pattern and breakage affect how much extra material to order.

This is an early quantity estimate. Site conditions, drawings, product details and workmanship can change the final requirement.

Understand your result

What this answer means

What it means

The calculation links brick modules to mortar void volume, then separates dry mortar into cement and sand by the entered ratio.

What to check next

Confirm the wall bond, brick size, joint thickness, mortar mix and bag mass in the project specification.

Common mistake

A brick count alone cannot determine cement and sand without modelling the joint volume and dry-volume allowance.

Check final plans with a professional

Use this calculator only for an early quantity estimate. A qualified civil or structural engineer must decide the final structure, reinforcement and safety details.
