Estimating bricks
A single-leaf wall of standard bricks needs roughly 60 bricks per square metre once mortar joints are included. Multiply your wall area by that figure and add about 10% for cuts, breakage, and the odd reject. Double-leaf (two-brick-thick) walls or different brick sizes change the count significantly.
