GQ Calc

GQ Calc (Get Quick Calculations) is a statically generated library of transparent material estimators for US homeowners, DIYers, landscapers, and small construction teams. The current release includes 50 free calculators across Concrete & Masonry, Landscaping, Walls & Ceilings, Flooring & Tile, Lumber & Carpentry, and Roofing Geometry. Every calculator keeps geometry, editable product assumptions, waste, whole-package rounding, and result limitations visible. US customary and metric inputs share the same internal formulas. The tools help turn job-site measurements and product-label coverage into clear material quantities, purchasable package counts, rounding excess, and project-cost estimates. GQ Calc is designed for real construction and home-improvement projects and works directly in the browser without an account. The calculators estimate material quantities; they do not provide structural design, code compliance, installation approval, product suitability, or professional advice.
