8x3 Timber C16/C24 Grade

Also referred to as 8 x 3 wood or 3 x 8 timber, this relates to the old imperial sizes of 8 inch by 3 inch and 3 inch by 8 inch. Sold by the stated nominal size of 75 x 200mm, the actual finished size of the sawn carcassing timber is around 70 x 195mm but may vary slightly. The lengths of carcassing timber are regularised (regged) which gives a smoother edge that takes 5mm from nominal width and 2mm from the nominal thickness. Slightly rounded edges along the lengths are then achieved after this process which improves handling

Do I need C16 Timber or C24 Timber? What's the difference?

If you need wood for structural support, kiln-dried softwood like C16 and C24 are popular choices, but understanding their differences is key to a successful project.


Grading acts like a strength ranking. C24, the top performer, excels with exceptional strength and near-perfect appearance. C16, a close second, offers solid strength with possible minor imperfections.


Need maximum power? C24's the go-to. Perfect for heavy-duty uses like beams or load-bearing walls. C16, while robust, works best for less demanding tasks like stud walls or internal structures.

Always remember:

C16 and C24 grades are both suitable for construction. The key lies in matching the specific needs of your project with the strengths and characteristics of each grade.

Things to consider that effect grading:

• Knots - More knots mean less strength
• Insect damage or woodworm holes
• Shakes or splits along the grain of the wood
• Slope of the grain
• Wane - bark or a lack of wood fibre on the edge of a piece of lumber

8 x 3 C24 timber is visually graded and is therefore a higher quality product.

Owing to the ever increasing demand, most locations in the UK will now supply C24 graded timber. In some regions though, 8x3 C16 timber will be supplied. If you have a specific requirement, please check before buying.

What is 8 x 3 Timber used for?

C24 8x3 timber offers impressive strength, perfect for structural applications such as:

• Wall framing

• Timber rafters

• Roof joists

• Floor joists

• Base for decking (must be treated if used externally)

If you need to know more about 8x3 rough sawn timber, we have great timber for roofing blog.

If you're planning on using 3x8 timber for 200mm joists, care must be taken to ensure the clear spans are suitable to take the required load. If you're not sure, check the Span Table.
