When embarking on any construction or woodworking project, selecting the right materials is paramount to achieving both aesthetic appeal and structural integrity. For those drawn to the natural beauty, durability, and pleasant aroma of cedar, understanding its grading system is essential. Two of the most commonly encountered grades are #1 Cedar and #2 Cedar. While both are genuine cedar, their differences in appearance, knot content, and suitability for various applications can be significant. This comprehensive guide will delve deep into the distinctions between #1 and #2 cedar, empowering you to make informed decisions for your next project.
What Defines Cedar Lumber Grades?
Before we dissect the specifics of #1 and #2, it’s crucial to grasp the fundamental principles behind lumber grading. Lumber grades are established by industry standards, primarily through organizations like the Western Wood Products Association (WWPA) for Western species like Western Red Cedar and Idaho Cedar. These grading systems are designed to categorize lumber based on its visual characteristics, particularly the presence, size, and location of knots, as well as other natural defects like checks, splits, and wane. The primary goal of grading is to provide a consistent and predictable way for consumers to select lumber suitable for their intended use and budget. Higher grades generally indicate more visually appealing lumber with fewer defects, while lower grades may contain more knots and imperfections but can still be perfectly functional for many applications.
A Deep Dive into #1 Cedar
1 Cedar is often considered the premium grade, representing the finest available cedar lumber. It is characterized by its superior visual quality, making it a highly sought-after material for applications where aesthetics are a top priority.
Appearance and Visual Characteristics of #1 Cedar
The defining feature of #1 Cedar is its remarkable visual appeal. You can expect lumber with a predominantly clear face, meaning it will have very few, if any, knots. When knots are present, they are typically small, tight, and well-encapsulated, posing no threat to the structural integrity of the board. The color of #1 Cedar can range from a rich, warm reddish-brown to a lighter, creamy blonde, often exhibiting a pleasing consistency across the board. The grain patterns are generally straight and uniform, contributing to its elegant and sophisticated appearance.
Knot Content in #1 Cedar
As mentioned, #1 Cedar is graded for minimal knotting. The standards allow for very limited, small, tight knots. These knots are firm, well-seasoned, and do not extend through the board. They are essentially ornamental and do not detract from the wood’s strength or workability. This scarcity of knots is a primary reason for its premium status and higher cost.
Suitability and Applications for #1 Cedar
The pristine appearance of #1 Cedar makes it ideal for a wide array of visible applications where visual perfection is paramount.
- Exterior Siding: Its ability to resist weathering, rot, and insect infestation, combined with its beautiful grain and color, makes #1 Cedar an excellent choice for premium exterior siding, from traditional clapboard to contemporary shiplap.
- Decking: For those who desire a flawless and luxurious outdoor living space, #1 Cedar decking offers unparalleled beauty and durability.
- Fencing: A fence crafted from #1 Cedar provides a sophisticated and long-lasting boundary.

Understanding #2 Cedar
2 Cedar, while still a quality cedar product, is a more utilitarian grade compared to #1. It allows for a greater presence of knots and other natural characteristics, making it a more economical choice for many projects where minor imperfections are acceptable.
Appearance and Visual Characteristics of #2 Cedar
2 Cedar exhibits a more rustic and character-filled appearance. It will contain a higher number of knots than #1 Cedar, and these knots can be larger and may not always be tight or firmly set. The color can also be more varied, with more pronounced differences between boards. While it still possesses the inherent durability and aroma of cedar, its visual appeal is less pristine.
Knot Content in #2 Cedar
The grading standards for #2 Cedar permit a significantly higher knot count than #1 Cedar. Knots in #2 Cedar can be larger, round or oval, and may be loose or sound. These knots can extend through the board and may occasionally have small amounts of bark in the edges. While these knots do not typically compromise the structural integrity of the wood for many applications, they are a noticeable visual characteristic.
Suitability and Applications for #2 Cedar
Despite its higher knot content, #2 Cedar remains a very capable and cost-effective material for a wide range of building and woodworking applications.
- Deck Framing and Joists: While #1 Cedar might be preferred for the decking boards themselves, #2 Cedar is an excellent and economical choice for the structural framing of decks, as the knots are usually not visible once the deck is completed.
- Fencing Posts and Rails: For the underlying structure of a fence, #2 Cedar provides the necessary durability and rot resistance at a lower price point.
- Shed and Outbuilding Construction: For the walls, roofing, and framing of sheds, garages, and other ancillary structures where pristine appearance is not the primary concern, #2 Cedar is a practical and durable option.
- Utility Buildings and Structures: Any construction that prioritizes function over form can benefit from the cost-effectiveness of #2 Cedar.
- Wood Paneling (Rustic Applications): For a more rustic or cabin-like interior aesthetic, the knots in #2 Cedar can add character and charm.
- Farm Structures: Barns, stables, and other agricultural buildings can utilize the natural resilience of #2 Cedar.
- Some Decking Applications: While not as visually perfect as #1 Cedar, #2 Cedar can be used for decking where a more knotty, natural look is desired, or where budget is a significant consideration.

Factors to Consider When Choosing Between #1 and #2 Cedar
The decision between #1 and #2 Cedar ultimately hinges on a combination of project requirements, aesthetic preferences, and budget constraints.
Aesthetics vs. Functionality
The most significant factor influencing your choice will be the intended visibility of the finished project. If the cedar will be prominently displayed and visual perfection is a high priority, investing in #1 Cedar is likely the best course of action. For structural components or applications where the material will be largely hidden from view, #2 Cedar offers a practical and economical solution without sacrificing the inherent benefits of cedar.
Budget Considerations
As a general rule, #1 Cedar will be more expensive than #2 Cedar due to its superior visual quality and limited defects. If you have a tight budget, #2 Cedar can allow you to achieve a cedar aesthetic for less, particularly for larger projects or structural elements. Carefully consider how much of the material will be visible to determine if the cost difference is justified.
Project Specifics
The type of project itself plays a crucial role. For a high-end custom home’s exterior siding or a luxury deck’s surface, #1 Cedar might be the standard. Conversely, for the framing of a garden shed or a fence’s foundational posts, #2 Cedar will likely suffice and prove more cost-effective. If you are using cedar for a project where you want a consistent, clear look, but your budget is tight, you might consider using #1 Cedar for the most visible parts and #2 Cedar for less prominent areas, provided the knots in the #2 grade are acceptable for those specific applications.
Workability and Durability
It’s important to note that both #1 and #2 Cedar are sourced from the same species of cedar and therefore share the same fundamental properties of natural resistance to rot, decay, and insect infestation. Both grades are also easy to work with, cut, and fasten. The primary difference lies in the visual appearance dictated by the presence and severity of knots and other minor surface imperfections.
Conclusion: Making the Right Choice for Your Cedar Project
Choosing between #1 and #2 Cedar is not about selecting a “good” or “bad” material; rather, it’s about selecting the appropriate material for your specific needs. #1 Cedar offers the pinnacle of visual perfection, making it the ideal choice for projects where aesthetics are paramount.

By understanding the grading criteria, considering the visual requirements of your project, and being mindful of your budget, you can confidently select the grade of cedar that will best contribute to the success and longevity of your build or woodworking creation. Whether you opt for the pristine elegance of #1 Cedar or the character-rich charm of #2 Cedar, you are investing in a material renowned for its natural beauty and enduring performance.
What is the primary visual difference between #1 and #2 cedar lumber?
The most noticeable distinction between #1 and #2 cedar lumber lies in the presence and size of knots. #1 grade cedar is characterized by its relative freedom from knots. When knots are present, they are typically sound, tight, and small, allowing for a more uniform and aesthetically pleasing appearance. This grade is often favored for applications where visual appeal is paramount.
In contrast, #2 grade cedar lumber will exhibit a greater number of knots, and these knots may be larger and potentially looser or have encased bark. While still functional, the increased knotting can affect the overall visual uniformity and may be perceived as less refined. This grade is generally considered more rustic in appearance.
How do the grading standards for #1 and #2 cedar impact their usability in different projects?
The grading standards directly influence the suitability of #1 and #2 cedar for various construction and finishing projects. #1 grade, with its minimal knotting, is ideal for applications where a clean, smooth finish is desired, such as premium siding, fencing, decking, and interior trim. Its uniformity also makes it easier to work with and finish consistently, leading to a more polished final product.
2 grade cedar, while more rustic, is perfectly functional for many outdoor and structural applications where aesthetics are secondary to durability and cost-effectiveness. This includes applications like general utility fencing, pergolas, outdoor furniture, and structural framing where knots do not compromise the integrity of the lumber. It offers excellent value for projects that don’t demand the pristine appearance of #1 grade.
Are there differences in the durability or structural integrity between #1 and #2 cedar?
In terms of inherent durability and structural integrity, both #1 and #2 grades of cedar lumber are generally comparable. Cedar, in general, is known for its natural resistance to decay, rot, and insect infestation due to its natural oils. The grading system primarily focuses on visual characteristics, not fundamental wood quality or its resistance to the elements.
The presence of knots in #2 grade can, in some instances, slightly affect localized strength if the knots are large and loose, potentially leading to minor checks or splits over time under extreme stress. However, for most typical construction and finishing applications, the structural difference between the grades is often negligible and not a primary concern when selecting between them.
What is the typical cost difference between #1 and #2 cedar lumber?
Generally, #1 grade cedar lumber is more expensive than #2 grade. This price difference is directly attributable to the stricter grading criteria for #1, which requires a more selective milling process to minimize imperfections like knots and defects. The higher yield of usable material from a log when producing #1 grade is less, thus increasing its per-unit cost.
The cost savings associated with choosing #2 grade can be significant, making it a more budget-friendly option for projects where the aesthetic demands are less stringent. This makes #2 cedar a popular choice for DIY projects, larger-scale outdoor installations, and applications where the visual impact of knots is not a primary concern.
Which grade of cedar is generally preferred for high-end outdoor living spaces like decks and patios?
For high-end outdoor living spaces such as decks and patios where visual appeal and a premium finish are highly valued, #1 grade cedar lumber is typically the preferred choice. Its clean appearance, with minimal knots and a smooth surface, contributes to a sophisticated and inviting atmosphere, enhancing the overall aesthetics of the outdoor environment.
The uniformity and limited defects of #1 grade also mean less waste during installation and a more consistent look across the entire surface. While #2 grade can certainly be used and can still look attractive, #1 grade offers that extra level of refinement that often distinguishes a truly high-end outdoor living space.
Does the knot pattern in #2 cedar lumber offer any aesthetic advantages for certain styles of projects?
Yes, the knot pattern found in #2 cedar lumber can offer distinct aesthetic advantages for certain styles of projects, particularly those aiming for a more rustic, natural, or traditional look. The presence of knots can add character and warmth, contributing to a charming and inviting ambiance.
This grade is often chosen for applications like rustic fencing, country-style porches, barn-style structures, or even certain interior accent walls where a less formal and more organic appearance is desired. The natural imperfections become a feature, adding depth and visual interest that a perfectly clear board might not provide.
When considering a DIY project, how does the choice between #1 and #2 cedar affect ease of installation and finishing?
For a DIY project, the choice between #1 and #2 cedar can impact both ease of installation and finishing, primarily due to the presence and nature of knots. #1 grade cedar is generally easier to work with and finish because the absence of large or loose knots means fewer potential tear-outs when routing, planing, or sanding.
