Mortar Calculator helps homeowners, masons, and contractors estimate mortar quantities for brick, block, stone, and paving projects.
Our Story
Mortar Calculator started with a common jobsite frustration: ordering too little mortar and stalling a build, or over-ordering and wasting money on material that hardens before it is used. After enough back-of-the-envelope math and mismatched bag counts, we built a simple, reliable estimator that anyone could use without a spreadsheet.
What began as an internal tool for our own masonry projects grew into a free public calculator. Over time we added support for brick, block, stone, and paving, along with metric and imperial units, adjustable joint thickness, mortar ratios, and waste factors. Today the site is used by homeowners, DIY builders, and working contractors to plan materials before the first course is laid.
What We Do
The site is focused on one practical job: turning project dimensions into a clear mortar estimate. Enter the build size, unit type, joint thickness, mortar type, and waste factor, then review the estimated mortar volume and material quantities.
Why It Exists
Mortar estimates are easy to undercount when joints, unit sizes, and waste are handled by rough guesswork. This tool keeps the calculation transparent so you can plan materials before work starts.
Accuracy
Results are planning estimates based on standard ratios and common masonry assumptions. Site conditions, workmanship, material variation, and local building requirements can change final quantities, so critical projects should always be checked by a qualified professional.
Our Team
Mortar Calculator is maintained by a small team with hands-on experience in masonry, construction estimating, and web development. Our builders sanity-check the calculation logic and mix ratios against real jobsite practice, while our editors keep the guides and FAQ clear and accurate. Content on this site is reviewed by the Mortar Calculator Team rather than published anonymously.
Company Information
Mortar Calculator is an independently operated business and web property. It is not a subsidiary of, or owned by, any parent company — the site is run and published directly by the Mortar Calculator team, which is solely responsible for its content, calculations, and editorial decisions. We are not affiliated with any cement, brick, or building-material manufacturer, and we do not sell mortar or masonry products.
