Use the calculator first
The quickest path is to start with Brick Calculator, then use this guide to sense-check the result and decide what to buy next.
Why this page exists
Best for wall-building jobs where the goal is to move from area into a sensible piece count, waste margin, and supporting mortar logic.
Core assumption
Masonry estimates depend on wall area, unit size, joint pattern, openings, and whether the buyer is ordering by piece count, pack, or pallet.
Common mistake
The most common problems are forgetting openings, using the wrong unit coverage rate, and overlooking mortar, cuts, and breakage at corners or reveals.
