Calculating Wood Movement

To use this chart: Multiply the width of the board by the amount in the blue-tinted column corresponding to its cut type, then by the percent change in moisture content to determine the amount of movement. For example, to calculate movement for a flatsawn red alder board 8" wide with a 6 percent change in moisture content: 8 x .0026 x 6 = .1248" (or about 1⁄8").
