Introduction

If you've been researching timber for a DIY, joinery or construction project, you've probably come across the term PAR timber. For many people, it's one of those industry phrases that appears regularly but isn't always clearly explained.

The good news is that PAR timber is actually quite simple to understand. In fact, it's one of the most versatile and widely used timber products available in the UK.

Whether you're building shelves, constructing furniture, creating decorative features or tackling home improvements, understanding PAR timber can help you achieve a cleaner, more professional finish.

In this guide, we'll explain exactly what PAR timber is, how it's produced, where it's commonly used and why it's often the preferred choice for interior timber projects.

What Is PAR Timber?

PAR timber stands for Planed All Round. This means the timber has been machined smooth on all four sides, creating a consistent finish and accurate dimensions.

Unlike rough sawn timber, which comes straight from the sawmill with a coarse surface, PAR timber has been carefully processed to remove imperfections and create a smooth, ready-to-use product.

This makes it ideal for projects where appearance matters as much as performance.

Because the timber has already been planed, it typically requires less preparation before painting, staining or installation.

Why Is It Called Planed All Round?

The name simply describes the manufacturing process. After the timber has been cut to size, it passes through specialist machinery that planes every face of the timber.

This process creates:

• Smooth surfaces

• Consistent dimensions

• Rounded or eased edges

• Improved appearance

The result is a timber product that is easier to handle, easier to finish and more suitable for visible applications.

Understanding this process helps explain why PAR timber is often chosen for joinery and decorative work.

PAR Timber vs Sawn Timber

One of the most common questions people ask is whether they should choose PAR timber or standard sawn timber.

The biggest difference is the finish.

Sawn timber has a rougher appearance and is often used where the timber will be hidden within a structure. PAR timber has a smooth, finished appearance designed for projects where the timber remains visible.

For example, structural framing may use sawn timber, while shelving, furniture and decorative projects often benefit from PAR timber.

Neither option is necessarily better; they simply serve different purposes.

Common PAR Timber Sizes

One advantage of PAR timber is the wide range of sizes available.

Because it is often used for joinery and finishing work, PAR timber is available in dimensions suited to furniture making, shelving, trim work and decorative installations.

Common sizes include:

• 44mm x 18mm

• 69mm x 18mm

• 94mm x 18mm

• 144mm x 18mm

Exact dimensions vary depending on the project and supplier.

Understanding available sizes helps ensure you choose timber that balances strength, appearance and practicality.

Why PAR Timber Is Popular for DIY Projects

DIY enthusiasts often favour PAR timber because it simplifies project preparation.

Since the timber arrives already planed and smooth, less sanding and finishing work is required before installation. This saves time and helps achieve a more professional result.

Projects such as shelving, storage units, benches and decorative wall features are all excellent applications for PAR timber.

For beginners, the ease of use can be particularly beneficial.

Best Uses for PAR Timber Around the Home

One reason PAR timber remains so popular is its versatility.

It can be used in a wide variety of interior projects, including:

• Shelving

• Furniture

• Window boards

• Decorative panelling

• Storage solutions

Its clean appearance makes it suitable for both functional and decorative applications.

This flexibility has made PAR timber a favourite among homeowners and professional joiners alike.

Is PAR Timber Suitable for Furniture Making?

Furniture making is one of the most common applications for PAR timber.

The smooth finish and consistent dimensions make it easier to achieve precise joints and attractive final results. Many furniture makers choose PAR timber because it reduces preparation time while maintaining a professional appearance.

Tables, shelving units, benches and storage furniture can all benefit from using planed timber.

For projects where appearance matters, PAR timber is often an excellent choice.

Can PAR Timber Be Used Outdoors?

Although PAR timber is primarily associated with interior projects, some versions can be used outdoors when properly treated.

Outdoor use requires additional protection against moisture and weather exposure. Treated PAR timber can be suitable for certain garden features, decorative structures and external joinery applications.

However, untreated PAR timber is generally best reserved for dry indoor environments.

Choosing the correct treatment level is important for long-term durability.

The Advantages of Choosing PAR Timber

There are several reasons why both DIYers and professionals choose PAR timber regularly.

The key benefits include:

• Smooth finish

• Consistent dimensions

• Reduced preparation time

• Improved appearance

These advantages help create projects that look more professional while reducing overall workload.

Common Mistakes When Buying PAR Timber

One mistake people often make is assuming all PAR timber products are identical.

Timber species, dimensions and moisture content can all influence performance. It's important to choose timber that matches the requirements of the project rather than selecting solely on appearance.

Another common mistake is forgetting that planing reduces the final finished dimensions compared to rough sawn timber.

Understanding these differences helps avoid problems during installation.

Why Buying PAR Timber from a Specialist Matters

Quality matters when purchasing PAR timber. Properly machined timber is easier to work with, more consistent and produces better results.

Many customers browsing timber products through Woodworks Timber appreciate the ability to choose from a range of PAR timber options suited to everything from simple shelving projects to larger joinery applications.

Expert advice can also help ensure the correct size and timber type are selected from the outset.

Sustainability and Responsible Timber Choices

Like many timber products, PAR timber can be a sustainable material when sourced responsibly.

According to Timber Development UK, responsibly managed timber products help support sustainable construction practices while providing a renewable alternative to many other building materials.

Choosing quality timber and using it efficiently benefits both projects and the environment.

Final Thoughts: Is PAR Timber Right for Your Project?

Understanding PAR timber is an important step when planning DIY, joinery or home improvement projects.

Its smooth finish, accurate dimensions and versatility make it one of the most useful timber products available. Whether you're building furniture, creating shelving or installing decorative features, PAR timber offers a practical and professional solution.

By choosing the right size, the right timber species and a trusted supplier, you'll be well positioned to achieve a high-quality finish that lasts.
