How to use the 9-Inch Brick Wall Calculator

A 9-inch brick wall is the standard load-bearing wall used across Pakistan and India, and its brick count follows a simple rule: about 13.5 bricks cover one square foot of wall including mortar joints. This calculator multiplies your wall length by its height to get the area, then applies that rate so you can order the right quantity in one trip. Under-ordering stalls the mason, while over-ordering wastes money on bricks that crack in storage, so an accurate estimate before you visit the kiln or dealer saves both time and cash.

Formula

Bricks = wall length (ft) × wall height (ft) × 13.5 for a 9-inch wall (6.75 for a 4.5-inch wall), then multiply by 1.05 to add 5% wastage for breakage and cuts.

Worked example

A boundary wall 10 feet long and 10 feet high gives 100 square feet. At 13.5 bricks per square foot, that is 1,350 bricks. Adding 5% wastage brings the order quantity to 1,418 bricks — so you would order roughly 1,420 bricks from the kiln.
