Half of every DIY budget disappears in “just-buy-a-few-extra” guesswork. I hit that wall swapping kitchen tiles and hunting for a lighting formula that wasn’t locked behind a signup. So I built a zero-friction hub where the math is instant, the interface is calm, and every tool is free. What’s new & unique 4 pro-grade calculators under one roof – tile, flooring, lighting and even solar-panel sizing—no separate apps, one bookmark calculateproject.com calculateproject.com Unit-agnostic inputs – mix feet, meters, inches; results update live. Smart padding – waste factors for diagonal, herringbone or roll seams baked in (no more “add 10 %… I guess?”). Edge-served & tracker-free – pure HTML/CSS/JS on Cloudflare; 100/100 Lighthouse, loads fast on job-site Wi-Fi. Built-in mini-guides – every calculator comes with a step-by-step explainer so first-timers know why the numbers matter. What we’re proud of In <50 KB of code we turned spreadsheet chaos into a two-minute workflow for weekend renovators—and kept it completely anonymous and ad-light. Fire it up, plan your project, and tell me what you’re building. Let’s nail that renovation on budget! 🛠️🏡
