If you choose more than \u201cNone\u201d, enter each opening\u2019s <strong>width<\/strong> and <strong>height<\/strong> and pick the shared <strong>Opening unit<\/strong> (ft, in, or m).<\/li>\n<li>Pick a <strong>Brick size<\/strong>: US modular 7\u215d \u00d7 2\u00bc in, US standard 8 \u00d7 2\u00bc in, UK 215 \u00d7 65 mm, or <strong>Custom size<\/strong>. For a custom brick, enter the face <strong>length<\/strong> and <strong>height<\/strong> in inches or millimetres.<\/li>\n<li>Enter the <strong>Mortar joint thickness<\/strong> \u2014 3\/8 in is typical in the US, 10 mm in the UK.<\/li>\n<li>Choose the <strong>Wall type<\/strong>: single wythe (one layer of bricks) or double wythe (two layers).<\/li>\n<li>Set the <strong>Waste allowance<\/strong> (5\u201310% is common) and, optionally, <strong>Mortar bags per 1,000 bricks<\/strong> and <strong>Price per brick<\/strong> to get a cost estimate.<\/li>\n<li>Read the results: net wall area, bricks per ft\u00b2, the number of bricks to buy, mortar bags, and estimated cost.<\/li>\n<\/ol>\n<h2>What the brick calculator does<\/h2>\n<p>This calculator estimates the number of bricks needed to build a wall based on its dimensions, the brick size, and the mortar joint. It subtracts windows and doors, adds a waste allowance, and converts everything into practical purchase quantities: bricks, bags of mortar, and \u2014 if you enter a price \u2014 the material cost.<\/p>\n<p>The key step is the brick density, bricks per square foot. A brick laid on the wall occupies its face length and height plus half a mortar joint on each exposed side \u2014 in practice the joint is added to both dimensions. Dividing 144 square inches by the area of this brick-plus-joint rectangle gives how many bricks cover one square foot. For a US modular brick with 3\/8 in joints that is about 6.86 bricks per ft\u00b2; for a UK standard brick with 10 mm joints it is about 60 bricks per m\u00b2.<\/p>\n<p>The two result counts answer different questions. \u201cBricks needed (before waste)\u201d is the theoretical count from geometry alone. \u201cBricks to buy (incl. waste)\u201d adds your waste allowance and rounds up to a whole number \u2014 this is the figure to order. Cuts at openings and corners, damaged bricks, and colour-matching across batches all make some surplus essential.<\/p>\n<p>The mortar result uses the classic rule of thumb of about seven 80 lb bags of premixed mortar per 1,000 modular bricks. If you are mixing your own from masonry cement and sand, or using larger or smaller bricks, adjust the rate \u2014 the <a href=\"https:\/\/wpcalc.com\/en\/life\/sand-calculator\/\">Sand calculator<\/a> can help you estimate the sand volume for a custom mix.<\/p>\n<h2>Assumptions, limitations and tips<\/h2>\n<ul>\n<li>The calculator assumes a <strong>running bond<\/strong> pattern with bricks laid on their faces. Flemish bond, herringbone, and other decorative patterns use more bricks because of extra cuts.<\/li>\n<li>Only the wall face is counted. A <strong>double wythe<\/strong> (two layers) doubles the count, but piers, columns, and footings need to be estimated separately.<\/li>\n<li>Openings are subtracted as simple rectangles. In reality, a lintel and extra cuts around each opening use additional bricks, which the waste allowance should cover.<\/li>\n<li>A 5% waste allowance suits simple, rectangular walls; use 10% or more for walls with many openings, intricate details, or thin mortar joints, where more bricks end in cuts.<\/li>\n<li>Bricks are sold in cube or pack quantities, so round up to the nearest pack when ordering. Mortar estimates vary with joint thickness, brick absorption, and mix design, so treat the bag count as a planning figure.<\/li>\n<li>The cost estimate covers bricks only. Mortar, sand, wall ties, lintels, flashing, and labour are extra \u2014 for other materials in the project, see the <a href=\"https:\/\/wpcalc.com\/en\/life\/square-footage-calculator\/\">Square Footage calculator<\/a> and the <a href=\"https:\/\/wpcalc.com\/en\/life\/drywall-calculator\/\">Drywall calculator<\/a> for interior finishes.<\/li>\n<li>Check local building codes before building: many regions require minimum wall thickness, ties, and reinforcement for brick walls.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Estimate how many bricks you need for a wall of any size.
