Planed Softwood Timber 16x100mm (0.5 x 4 inch) finished size 12x94mm is planed timber designed for interior carpentry where a smooth, finished appearance matters. It’s available in a range of lengths to suit everything from small fixes to larger builds.

Nominal size is 16x100mm; finished size is 12x94mm. The timber is softwood and planed on all faces, with two common finish options: Planed Square Edge (PSE) or Planed All Round (PAR). PAR has all faces planed and is typically used where every side is visible, and it tends to cost more than PSE.

interior use is the norm, with exterior use possible if the timber is properly treated. Planed timber accepts stains, oils and lacquers well, making it versatile for a variety of finishes. The smooth, splinter-free surfaces help achieve a clean look on shelves, panels and joinery.

  • Smooth planed surfaces with minimal splinters for easier handling on site
  • Suitable for staining, oils or lacquers to achieve different finishes
  • Lengths range from 0.9 m up to 4.2 m to cover a wide range of projects
  • Ideal for interior applications such as shelving, sash windows and feature pieces; can be used outside with proper treatment
  • Competitive pricing achieved through direct sourcing and stock availability

Practical tips for best results: acclimatise the timber in a dry environment before cutting to minimise movement after fitting. Store timber off the ground in a dry, well-ventilated area. When installing externally, apply an appropriate treated coating or finish to protect against moisture and mould. Plan for minor size changes after installation by allowing for expansion gaps where appropriate, and pre-drill to reduce the risk of splitting on nailing or screwing.

Smooth Finish, Square Edges

This planed timber is machined on all faces to produce a smooth surface and crisp square edges. It reduces splintering and helps you achieve a clean finish in visible areas. It suits shelves, linings, trims, and general carpentry where straight lines matter.
The PSE profile supports accurate fitting because the faces are consistent and easy to mark out. It also makes finishing quicker, as the surface is already smooth and ready for coating.

Length Options for Better Planning

This timber is available in length variants from 0.9m to 4.2m, which helps match material to your cut list. Shorter lengths work well for repairs, braces, and smaller joinery tasks. Longer lengths suit continuous runs such as shelving rails and straight battens where fewer joins improve the finish. Choosing the right length reduces waste and speeds up installation.

Nominal vs Finished Size

The nominal size of 16x100mm refers to the section before machining. Once planed, the finished size supplied is 12x94mm. This difference matters when setting out work, especially where timber must fit into tight openings or align with existing pieces. Use the finished size for accurate spacing, fixing positions, and final appearance.

Ready for Paint, Stain, or Oil

This softwood is easy to cut, drill, and fix with standard tools. The smooth face accepts paint, stain, oil, or lacquer, giving you control over the final look. It is commonly used for interior joinery, but can be used externally when treated correctly. Treatment helps protect against moisture and improves service life in exposed settings.

Clear Coverage and Weight Control

Coverage is simple because this is a linear product, so each variant covers its stated length. With an approximate weight of 575g per metre, you can estimate handling and loading more accurately. The weight scales with length, which helps when ordering mixed sizes for a project. Using one consistent profile also improves alignment across multiple runs, keeping the finish neat.
