ProjectMetrica builds free calculators and practical guides for homeowners, DIYers and anyone planning a home or yard project. The goal is simple: make the material math visible before money is spent.
What ProjectMetrica does
Our tools convert project dimensions into planning quantities such as cubic yards, tons, bags, rolls, pallets, blocks, panels and estimated project costs. We focus on calculations that are useful before ordering materials or comparing quotes.
How we build the calculators
Each calculator shows the assumptions behind the result. Where a material density, waste allowance, supplier coverage or local price can vary, the input is editable so the estimate can be matched to the actual project.

What our estimates are not
ProjectMetrica is a planning resource, not an engineering, architectural, surveying or contracting service. Site conditions, building codes, manufacturer requirements and local prices can materially change a project. Verify the final specification before purchasing materials or starting work.
Corrections and partnerships
If you find a calculation issue, outdated assumption or content that could be clearer, please contact us. We also welcome relevant partnership enquiries, but commercial relationships do not change the formulas used in our calculators.
