ProjectQty
Construction quantities with formulas you can inspect
ProjectQty provides 41 free construction material calculators for concrete, gravel, roofing, flooring, landscaping, and related DIY planning jobs. It helps homeowners, DIY planners, and lightweight construction teams turn measurements into order-ready quantities with formulas they can inspect before buying materials.
The product focuses on transparent estimating rather than black-box project management. Each calculator shows the assumptions, unit conversions, waste settings, rounding behavior, and worked quantity logic behind the result. Users can plan in imperial or metric units, compare material quantities, print or share result pages, and keep browser-local project guides without creating an account.
ProjectQty is useful when someone needs a quick but defensible material estimate for a slab, gravel base, mulch bed, paint job, flooring layout, roofing project, masonry wall, fence, patio, or similar field task. The site is free to use and does not require sign-up.
