Square Foot Calculator was created to give homeowners, installers, contractors, and DIY planners a cleaner way to estimate area, material quantity, and project cost — all from one free tool.

Who We Are

Square Foot Calculator is a small, focused team of web developers, engineers, and content specialists who build practical measurement tools for the web. We combine real-world construction, renovation, and landscaping knowledge with clean, modern software so that anyone can calculate area and material needs without guesswork.

Parent company: Square Foot Calculator is owned and operated by Rankviz, an independent digital products company. Rankviz is the legal entity and parent company responsible for the development, maintenance, and editorial standards of this website.

Our Story

Most online area calculators felt dated, confusing, or too limited for real-world jobs. We wanted a square foot calculator that combined polished design with practical utility — so we built one.

What started as a single rectangle area tool has grown into a full suite supporting 15 geometric shapes, automatic unit conversions, quantity planning, waste-factor estimation, and material cost calculation. Whether you are laying flooring, measuring a patio, or pricing landscape materials, the goal has stayed the same: get to an accurate estimate with less friction.

What We Do

We design and maintain free, browser-based calculators that turn measurements into actionable estimates. Our tools and services include:

• ✓ 15 shape formulas — rectangle, circle, triangle, trapezoid, L-shape, annulus, sector, parallelogram, and more
• ✓ 41 specialized calculators — room, kitchen, flooring, tile, paint, roofing, lawn, pool, driveway, and more
• ✓ Instant unit conversion — sq ft, sq yd, sq m, acres, sq in
• ✓ Material cost estimation — enter price per unit to get project totals
• ✓ Waste factor built in — add 10-15% surplus for cuts and breakage
• ✓ 100% free — no signup, no limits
