Find Your Calculator

MasonCalc is a specialized online tool designed to help homeowners, DIY enthusiasts, and professional contractors accurately estimate the number of bricks, blocks, and mortar needed for any masonry project.

Simply select your masonry type (standard brick, modular brick, or concrete block), enter the dimensions of your wall (length and height), and input the size of your doors or windows. The calculator will handle the math for you.

Yes. You can enter the dimensions of any “openings” in your wall, and the calculator will automatically subtract those areas from the total material count to ensure you don’t overbuy.

As a general rule, one bag of mortar typically covers about 35–40 standard bricks or 8–10 concrete blocks. Our calculator provides a more precise estimate based on your specific wall area.

Yes, we recommend adding a 10% “waste factor” to your final count. This covers any bricks or blocks that may break during delivery or need to be cut to fit corners and edges.

The most common sizes are: Standard Brick (8″x2.25″x4″), Modular Brick (7.625″x2.25″x3.625″), and Concrete Block (16″x8″x8″).

By providing the total unit count, MasonCalc gives you the foundation to calculate costs. Simply multiply the results by the local price per unit at your hardware store.

Yes, the calculator is designed to support various units of measurement to ensure it’s useful regardless of your location or project requirements.

While MasonCalc provides accurate material estimates, we recommend consulting with a structural engineer or professional mason for load-bearing walls to ensure safety and code compliance.
