How much wastage should I allow?
Five to ten percent is typical for cutting and breakage. Complex openings and patterns may require up to fifteen percent.
Brick Calculator
Estimate brick count, mortar volume, and pack requirements for masonry walls.
Brick Calculator Formula
- Wall Area
Wall Length × Wall Height - Wall Volume
Wall Area × Wall Thickness - Brick Volume with Mortar
(L + mortar) × (H + mortar) × (W + mortar) - Bricks Required
Wall Volume ÷ Brick Volume × (1 + Wastage %) - Mortar Volume
Wall Volume − (Net Brick Volume × Brick Count)
Assumptions
- Preset brick sizes use common nominal dimensions for standard, modular, and engineering types.
- Mortar thickness is applied uniformly on all sides of each brick.
- Recommended packs assume 500 bricks per pack.
Frequently Asked Questions
What if I use custom brick sizes?
Select the custom brick type and enter length, width, and height in the same unit as the wall dimensions.
Is mortar volume exact?
Mortar volume is an estimate based on net brick volume within the wall. Actual mortar use varies with joint profile and workmanship.
