Calculators
Simple paint, flooring and tile calculators for early project planning.
Trazi calculators show the math behind early project estimates. They are intentionally editable: use the coverage, waste and carton figures from the exact product you plan to buy.

Coverage and waste are not universal constants. Surface texture, pattern, room shape, batch matching and manufacturer instructions can change the required quantity. Use the calculator for transparent arithmetic, then round purchases according to the product packaging.
