Hey Product Hunt community! 👋 Estimating materials for masonry and retaining walls is often either needlessly manual with scratchpads or locked behind bloated, ad-cluttered contractor tools. I built Block Wall Calculator to fix that. It is a lightweight, zero-fluff utility designed to give accurate material estimates in seconds—whether you're planning a DIY garden retaining wall, a cinder block privacy fence, or a full structural boundary. What it handles out of the box: Accurate Quantities: Calculates standard CMU/blocks, mortar bags, core-fill grout, and rebar requirements based on wall dimensions. Waste & Cut Allowances: Configurable buffer percentages so you never run short mid-project. Cost Estimations: Plug in local unit prices to generate instant baseline budgets. Instant Export: Clean, printable summaries ready for hardware store runs or client quotes. Since this is a soft launch, my main goal today is gathering real-world feedback on the calculation edge cases and usability: Are there specific block sizes, bond patterns, or reinforcement standards you’d like added? What export formats (PDF, CSV, or shareable links) would make this most useful on an active job site?
