About Block Estimator

Block Estimator is a free set of planning tools for concrete block and brick masonry projects. Each tool works in imperial or metric units and shows the assumptions behind its result.

Calculators

• Concrete Block Calculator: blocks for a wall, with door and window deductions, a waste allowance and optional cost.
• Mortar Calculator: bags of premixed mortar, from the coverage printed on your bag.
• Block Fill Calculator: grout or concrete to fill block cells, from the cell size you enter.
• Concrete Footing Calculator: concrete to order for strip and rectangular pad footings.
• Brick Calculator: bricks for a wall, using a counting method you choose.
• Rebar Quantity Estimator: total bar length, stock bars to buy and approximate weight, from the bar schedule on your plans.

Reference and planning

• Block Sizes & Dimensions: a reference table of common nominal and actual block sizes and the wall area each covers.
• Project Material List: collects results from the tools into one list you can price, print or download.

How it works

No account is needed. Calculations run in your browser. Your measurements, prices and material list are saved in your browser's local storage on this device, so they're still there when you come back. They are not sent to us. You can clear them on the Privacy page.

Results are planning estimates. They are not structural design, engineering advice or confirmation of building-code compliance. Always confirm quantities with your supplier.
