Why is it Difficult to Find Custom Lumber Dimensions?

January 31, 2023
Custom Lumber Dimensions

A modern-day lumber mill in the U.S. is highly sophisticated and can turn logs into standard ready-to-use lumber in a matter of minutes. But what about custom lumber dimensions?

But the process is highly automated, using X-ray scanning, 3-D modeling, lasers, and a host of computer analysis to determine the maximum value of lumber a log can yield. For this reason, mills are rarely able to stop the production line to re-tool to run custom lumber dimensions and sizes.

Examples of standard lumber dimensions include:

  • No. 1, No. 2, No. 3., and studs (2˝ to 4˝ thick, 2˝ and wider)
  • No. 1 and No. 2 Prime (2˝ to 4˝ thick, 2˝ to 12˝ wide)

Examples of custom sizes include, but are not limited to:

  • Dense and non-dense select structural
  • No. 1 and No. 2 dense and non-dense
  • Construction (2˝ to 4˝ wide only)
  • Standard (2˝ to 4˝ wide only)
  • Utility (2˝ to 4˝ wide only)
  • Timbers: 5˝ x 5˝ and larger
  • E-rated Structural Laminations: 4˝ and less in thickness, 2˝ and wider
  • Glued Lumber: 4″ and less in thickness, widths vary by product
  • Scaffold Plank: 2˝ and 3˝ thick, 8˝ and wider
  • Stadium Grade: 2˝ thick, 4˝ to 12˝ wide
  • Seawall Grades: 2˝ to 4˝ thick, 6˝ to 14˝ wide
  • Marine Grades: 1˝ to 20˝ thick, 2˝ to 20˝ wide
  • Decking, Heavy Roofing and Heavy Shiplap: 2˝ to 4˝ thick, 4˝and wider

If you need custom lumber dimensions or sizes, it’s often best to order from a “remanufacturing” operation or export wholesaler with the capability to re-saw lumber into the desired size.
