About the Author

Mason ReidFounder and Lead Estimator at MeasureThen

Mason Reid founded MeasureThen after two decades of hands-on work in construction and estimating. Across residential and light commercial projects, he sized concrete pours, framed walls, hung drywall, and priced out roofing, fencing, and deck work — learning the exact math that every job depends on. At MeasureThen he writes the formulas, checks every calculator against real-world assumptions, and makes sure each one is simple enough for a homeowner to trust and a contractor to use. When he is not measuring twice, he is helping projects stay on budget.

Every MeasureThen calculator uses simple, transparent formulas and standard industry assumptions drawn from common construction practice. We show the math behind each result and include worked examples so you can follow along and double-check the numbers. Results are estimates: materials, labor, and pricing vary by region and market, so always confirm important figures with a licensed professional and your local building codes.

Our Approach

Every calculator uses simple, transparent formulas and standard industry assumptions. We show you the math behind each result and include worked examples so you can understand and double-check the numbers. We do not require accounts, and your inputs never leave your browser.

A Note on Accuracy

Our results are estimates. Materials, labor, and pricing vary by region and market, and real-world conditions differ from any formula. Always confirm important figures with a licensed professional and your local building codes. See our Disclaimer for details.
