ProjectQty is a free browser-based construction quantity calculator library for concrete, gravel, roofing, flooring, landscaping, and other material planning jobs. It helps homeowners, DIY planners, independent makers, and lightweight construction teams turn measurements into order-ready quantities without creating an account. Each calculator exposes formulas, assumptions, rounding behavior, waste allowances, and browser-local project guide notes, so users can understand the estimate instead of trusting a black-box number. ProjectQty is not a supplier quote, contractor marketplace, permit authority, or structural design service; it focuses on transparent quantity math before users compare products or order materials.
