How do I calculate how many bricks I need?

Calculate net wall area in square feet, divide by the brick face area including the mortar joint, then add a waste allowance and round up.

How much waste should I add for brick?

A 5-10% waste allowance is common for simple walls. Complex layouts, cuts and matching existing brick may need more.

Does this replace a masonry design?

No. It is a material estimate only. Structural masonry, reinforcement, wall ties, flashing and local code must be checked separately.

Modular brick, actual 7.625 x 2.25 x 3.625 in; 0.375 in mortar joint. Use this for material takeoffs; wall ties, flashing, lintels, and structural checks are outside this estimate.

Estimate bricks for a wall

English brick-calculator intent is a material takeoff: wall square footage, brick face size, mortar joint, openings, waste and cost. The result should help plan how many bricks or pallets to price before confirming the layout with a supplier.

W a l l a r e a = L e n g t h_{f t} \times H e i g h t_{f t} - O p e nin g s_{f t^{2}}

B r i c k s = ⌈ \frac{W a l l a r e a}{B r i c k f a ce a r e a} \times (1 + W a s t e) ⌉

What can change the order quantity

Actual modular, utility, queen, engineer and veneer bricks use different face dimensions.
Bond pattern, cuts, corners, returns, pilasters, openings and breakage can change the final count.
Structural masonry, flashing, wall ties, reinforcement and code details are outside a simple brick count.
