Concrete & Masonry Guide Estimating bricks starts with wall area, brick face dimensions and mortar-joint size. Because brick dimensions vary, the most accurate calculation uses the actual brick being installed. Quick answer: calculate the wall area, determine the installed face area of one brick including mortar joints, divide the wall area by that value and add waste. Calculate bricks automatically Enter wall dimensions, brick dimensions and waste to estimate the number of bricks you need. Use the Brick Calculator Square Footage Calculator Step 1: Calculate Wall Area Wall Area = Width × Height A wall 20 ft long and 8 ft high has an area of: 20 × 8 = 160 ft² Step 2: Subtract Large Openings If the wall contains doors or windows, calculate their areas and subtract them. A 3 ft × 7 ft door is: 3 × 7 = 21 ft² Usable brick area: 160 - 21 = 139 ft² Step 3: Determine Brick Module Size For wall calculation...

Landscaping Guide Topsoil is sold by volume, so estimating it requires both the surface area of your project and the depth of soil you want to add.
