Change the settings to your bricks

The brick size, joint, mortar mix, dry-volume factor and wastage are starting values — measure your bricks and use the mix your mason or engineer uses. Bricks differ from kiln to kiln. The PDF lists every setting with the answer, so the shop and the mason see how it was worked out.

Questions people ask

How many bricks are needed for a wall?

Wall volume ÷ the volume of one brick with its mortar joint, plus wastage. Enter the wall size and your brick size; the page works out bricks, cement bags and sand.

How much cement and sand for brick work?

From the mortar: wet mortar = wall volume - bricks, dry = wet × a dry-volume factor (1.33 by default, change it), split by your mix (e.g. 1:6) into cement and sand.

Can I get a cost estimate?

Yes — fill in the prices you were quoted for bricks, cement and sand; the PDF shows the amount for each and the total.

Is my data uploaded?

No. Everything is worked out in your browser and the PDF is made on your device.
