National Wood Floor Consultants has developed calculators to help guide you through some of the problem related areas to wood flooring.  These calculators are only a guide to provide approximations to the architect, general or flooring contractor, homeowner, designer, etc.  Wood flooring being commercial harvested and manufactured today may include both cuts of wood, quarter sawn and plain sawn.  Due to this scenario, there is no real scientific conclusion of expansion or contraction other than approximations.

These calculators can help you resolve differences of opinions and project many flooring problems before they arise.
