Standard sizes: thicknesses, widths and lengths

Dimensions mean nominal sizes with the moisture content of the sawn timber at 20%.

The most common lengths vary between 2.7 m and 5.4 m in steps of 300 mm. Other lengths and modules must be agreed separately. Thickness and width dimensions mean the nominal sizes of the timber at a moisture content of 20%.

The standard measurements of sawn, dimensioned and all-round planed timber are shown in the following tables:
