How to calculate square feet?
A good square foot calculator is available at http://jmhomeowner.com/toolbox/sqftcalc.asp or http://www.arroyohardwoods.com/Resources/Calculators.html. To figure out square footage without a calculator, you would take the length in feet and muliply it by the width in feet. For example a 12 X 9 room would equal 108 square feet.
