Instructions: Wood Shrinkage Calculator

Width:
Enter the actual measured width of the lumber, in inches and fractions of an inch (centimeters, if metric).

Initial Moisture Content:
Enter the initial moisture content(MC). Do not enter decimals or fractions, and do not enter the percentage sign after the value. Values over 30% MC will be calculated as 30% MC. It is generally accepted changes in MC above 30% do not affect dimension because free water is present.

Final Moisture Content:
Enter the final moisture content(MC). Do not enter decimals or fractions, and do not enter the percentage sign after the value. Values over 30% MC will be calculated as 30% MC.

Type of Lumber:
By default, flatsawn is the type of lumber chosen. If you would like to calculate the shrinkage for radialsawn lumber, choose the radialsawn option.
