Comfort Level: Wood flooring will perform best when the interior environment is controlled to stay within a relative humidity range of 30% to 50% and a temperature range of 60 to 80 degrees Fahrenheit. Fortunately that is about the same comfort range that most humans enjoy. The chart below indicates the moisture content wood will likely have at any given combination of temperature and humidity. Although some movement can be expected even between 6% and 9% humidity, wood can expand and contract dramatically outside that range.
