Use this free brick calculator for walls to estimate whole bricks from wall dimensions or area, openings, brick size, mortar joint, table coverage, and waste.
20 ft x 8 ft wall - 24 ft2 openings
Coverage tables may give a slightly different count. Bond pattern, corners, piers, wall thickness, and mortar quantities still need a separate takeoff.
Recent brick estimates will appear here.
Brick estimates stay local and use wall dimensions or area, openings, brick coverage, mortar joint, and waste.

Plain-language answers about when to use the tool, what it does with your inputs, what to double-check, and how privacy works.
Use it when your task matches one of these common needs: Estimate brick count from wall length and height. Subtract measured door and window openings before adding waste. It works best when you already know wall dimensions or area, opening area, brick dimensions or supplier coverage, mortar joint, and waste percent.
In plain language: Dimension method: gross wall area = length x height, net area = gross area - openings, bricks per square foot = 144 / ((brick length + joint) x (brick height + joint)), and bricks = ceiling(net area x coverage x (1 + waste / 100)). Coverage-table method: bricks = ceiling(net area x bricks per 100 square feet / 100 x (1 + waste / 100)). The examples on the page are there so you can compare your inputs with a brick-wall example before copying the answer.
Wall dimensions: the gross wall length and height before doors and windows are removed. Openings: the combined door, window, and other area subtracted from the gross wall face. Brick dimensions: the visible face length and height of one brick in inches. Mortar joint: the planned gap between bricks, included in the face coverage estimate. Coverage table: bricks per 100 square feet for the exact brick designation and joint from a supplier or BIA table. Waste percent: extra bricks for cuts, breakage, corners, bond pattern, and color matching.
Read the headline estimate first, then check the material, waste, coverage, and unit lines. For project tools, the supporting lines are often the difference between a rough idea and a list you can actually shop from.
Brick counts can change with supplier coverage tables, bond pattern, corners, piers, returns, cuts, wall thickness, damaged units, mortar, ties, flashing, and professional masonry layout. Also check whether your brick dimensions are actual face dimensions, whether the coverage rate matches the exact joint, and whether openings were already subtracted.
Use Wall dimensions when you measured length and height, Known area when you already have gross square feet, or Coverage table when a supplier or Brick Industry Association table gives bricks per 100 square feet for the exact unit and joint.
Use 3/8 inch only if it matches your plan or supplier guidance. The Brick Industry Association tables often show 3/8 inch and 1/2 inch joint examples, and changing the joint changes brick coverage.
Enter the combined opening area separately. The calculator subtracts it from the gross wall area before applying the brick coverage and waste allowance.
A table may account for the brick designation, nominal coursing module, joint, and estimating conventions. Use Coverage table mode when you have a rate for the exact product instead of forcing the face-dimension result to match it.
No. This page estimates brick count. Mortar depends on brick type, joint thickness, bed depth, collar joints, waste, and the mortar product, so price and bag counts should be checked separately.
Only for a rough face-count check. Patio and paver layouts often need base gravel, bedding sand, edge restraints, pattern cuts, and drainage planning, so use a paver-specific calculator for that job.
Supplier tables may use a different brick size, nominal dimension, joint width, wall type, or no waste. Match the exact brick face size and joint before comparing numbers.
