Estimate brick counts and mortar for wall area.

Educational US estimate only. Not engineering, structural, code, or professional construction advice. Mix designs, codes, and local conditions vary — verify with licensed professionals and your building department.

Estimator methodology

BuildToolsHub takeoffs separate net measured quantities from ordered quantities. Ordered qty = net × condition-based waste, then rounded for plant or package sizes (e.g. ready-mix to the nearest 0.5 yd³).

  • Concrete bags: Quikrete / SAKRETE published yields (80 lb ≈ 0.60 ft³). Ready-mix contingencies follow ASTM C94 purchaser practice.
  • Rebar: CRSI published lb/ft tables; optional lap allowance ≈ 40× bar diameter (confirm with drawings).
  • Roofing: NRCA squares (100 ft²); pitch factor √(1+(rise/12)²); ~3 bundles/square for standard shingles.
  • Aggregates / fill: ASTM C29-style densities; swell/compaction allowances for haul and place volumes.
  • Masonry: BIA / NCMA common unit factors (e.g. ~1.125 CMU/ft² for 8×16 face).

Use the Order tab for a supplier call sheet and the Assumptions panel for the exact factors applied to this run.

Why use Brick Wall Calculator

Enter wall area or dimensions and brick size to estimate unit counts with mortar joints and waste.

Bond pattern, openings, and soldier courses change counts. Verify with a mason for architectural work.

How to use

  1. Enter job dimensions. Pick a pour/layout condition to set industry waste %, or choose Custom.
  2. Review Net vs Order on the Summary tab — order the rounded quantity, not net alone.
  3. Open the Order tab for a supplier checklist, then print, export CSV, or share the link.

What waste percent is typical?

Often 5–10% for cuts and breakage; more for complex patterns.

Is this professional engineering advice?

No. Educational estimates only. Verify with a licensed professional and local codes.
