Description
25x150mm Planed Timber
Planed softwood timber with a nominal size of 25x150mm (1 × 6 inch) and a finished size of 19x144mm. Supplied as 5ths Redwood, this smooth planed timber is suited to shelving, internal carpentry, joinery, furniture, trim and general woodworking projects.
Nominal: 25 × 150mm | Finished: 19 × 144mm5ths Redwood
A traditional timber trade quality description for redwood softwood, suitable for a range of internal carpentry and woodworking applications.
Planed All Faces
The timber is planed to provide smooth faces, making it easier to work with and reducing preparation before finishing.
19 × 144mm Finished
The finished dimensions are smaller than the nominal 25 × 150mm size because material is removed during the planing process.
25x150mm nominal size — 19x144mm finished size
Timber is commonly sold using its nominal or trade size. Once the timber has been planed, the actual finished dimensions are smaller. This is normal for planed softwood and is why this product is listed as 25x150mm nominal but measures approximately 19x144mm finished.
What does 5ths Redwood mean?
This timber is graded and sold as 5ths Redwood. The term combines a traditional trade quality description with Redwood, the common UK timber trade term for a type of softwood used extensively for internal carpentry, joinery and general woodworking.
For buyers, the important point is that 5ths Redwood describes the timber's trade quality and appearance characteristics. It should not be confused with a structural strength class such as C16 or C24.
What "5ths" means
5ths is a traditional timber trade grading description used to indicate the quality and general appearance of redwood softwood.
As with other timber grades, characteristics such as knots, grain and overall appearance can influence the grade.
What is Redwood?
In UK timber terminology, Redwood is a common trade description for softwood used for applications including internal carpentry, shelving, joinery, furniture and general woodworking.
It is different from the American timber species commonly known as California Redwood.
Why does the grade matter?
Knowing the timber grade helps you understand what you are buying and whether the material is appropriate for your project.
5ths Redwood is particularly relevant where a planed, workable softwood is required for internal carpentry and woodworking rather than a specified structural strength class.
What can 25x150mm planed timber be used for?
The 19x144mm finished section gives you a useful, relatively wide piece of planed softwood for internal carpentry and woodworking. Common uses include:
Key features
Choosing the right planed timber size
Step 1 — Check the finished dimensions
Planed timber is smaller than its nominal size. For this product, the nominal 25x150mm dimensions become approximately 19x144mm after planing.
If your project requires a specific finished dimension, use the finished size rather than the trade size when planning your project.
Step 2 — Consider how the timber will be used
Consider whether you need the timber for shelving, joinery, trim, furniture, framing within a non-structural project or general woodworking.
If the project has a specified structural timber requirement, make sure the timber you select has the required structural grade.
Step 3 — Check the available lengths
This product has a Choose a Length option. Select the required length on the product page before adding the timber to your basket.
Step 4 — Allow for natural timber characteristics
Timber is a natural material. Knots, grain variation and other natural characteristics can occur. The 5ths Redwood grading gives you useful information about the trade quality of the timber, but individual pieces can still show natural variation.
Planed timber vs sawn timber
Planed Timber
- Smoother finished surfaces
- Reduced preparation before finishing
- Consistent finished dimensions
- Suitable for visible internal applications
- Easy to cut, drill and fix
Sawn Timber
- Rougher surface texture
- Usually requires more preparation for visible work
- Typically supplied at a larger sawn dimension
- Commonly used where a rough timber finish is acceptable
- Often selected for construction and general site work
Planning a project with 25x150mm timber?
For shelving
The 144mm finished width provides a useful shelf depth for many storage and workshop applications. Consider the span, expected load, support arrangement and fixing method when designing your shelving.
For furniture and woodworking
The smooth planed faces make this timber suitable for cutting, drilling, sanding and finishing as part of DIY furniture and woodworking projects.
For painting or staining
Planed timber generally requires less surface preparation than rough sawn timber. Depending on the finish required, light sanding, preparation and suitable primer or treatment may still be necessary.
For structural projects
Do not assume that a 5ths Redwood timber product is structurally graded simply because it is a substantial timber section. Where structural performance is required, use timber with the appropriate specified strength class and certification.

The nominal size is 25x150mm, while the finished planed size is approximately 19x144mm.
What does 5ths Redwood mean?
5ths Redwood is a traditional timber trade quality description for redwood softwood. It relates to the timber's trade quality and appearance characteristics rather than being a structural strength classification.
Is 5ths Redwood the same as C16 or C24?
No. C16 and C24 are recognised structural strength classes. 5ths Redwood should not automatically be treated as a C16 or C24 structural timber.
What can 25x150mm planed timber be used for?
Typical applications include shelving, internal carpentry, joinery, furniture, trim, storage projects and general woodworking.
Can planed timber be painted or stained?
Yes. The smooth planed surface is suitable for painting, staining or sealing after appropriate preparation and use of a suitable finishing system.
Why is the finished size smaller than 25x150mm?
Planing removes material from the timber to create smoother and more consistent surfaces. This is why timber sold as 25x150mm can have a finished dimension of approximately 19x144mm.
Is this timber suitable for structural work?
This product is described as 5ths Redwood rather than a structural strength class. If your project requires C16, C24 or another specified structural grade, use timber that has been specifically graded and supplied for that purpose.
25x150mm planed timber for carpentry and joinery
25x150mm planed timber is a versatile softwood section for internal carpentry, shelving, joinery, furniture making and DIY woodworking. Although commonly referred to by its 25x150mm or 1x6 inch trade size, the actual finished dimensions are approximately 19x144mm after planing.
This product is supplied as 5ths Redwood, providing a useful option where a planed redwood softwood is required for general internal woodworking. The smooth planed faces make the timber convenient to cut, drill, screw, nail and prepare for finishing.
When ordering planed timber, always check the finished dimensions rather than relying solely on the nominal timber size. This is particularly important when designing shelving, storage, trim, furniture or joinery where the finished dimensions need to fit a specific space.
