Questions about this calculator
Do I subtract windows and doors?
Yes. Enter opening area so bricks are not counted across voids.
Are mortar joints included?
Yes. Coverage assumptions include standard modular brick joint spacing.
Can I use mixed units?
Yes. Choose feet, inches, metres or centimetres and the calculator converts each input before calculating.
Is this a final material order?
No. Confirm drawings, product coverage, local code and site conditions before buying or building.
