5/8″ or 3/4″? Does board thickness really matter when building a fence?

Choosing Between 5/8″ and 3/4″ Western Red Cedar Fence Boards: What’s Best for Your Project?

When it comes to building a fence, selecting the right material is crucial for durability, aesthetics, and overall value. Western red cedar is one of the most popular choices for fencing due to its natural beauty, resistance to decay, and long lifespan. However, when deciding between 5/8″ and 3/4″ thick fence boards, there are key differences that impact durability, cost, and performance over time. In this blog post, we’ll explore the pros and cons of each option so you can make an informed decision for your fencing project.


Understanding Western Red Cedar

Western red cedar is renowned for its deep reddish-brown hues, rich grain patterns, and natural resistance to rot, insects, and weathering. Unlike pressure-treated lumber, it doesn’t require chemical treatments to withstand outdoor elements, making it an environmentally friendly and aesthetically pleasing choice.

However, within western red cedar fencing, the thickness of the boards plays a significant role in performance, longevity, and overall value. Let’s break down the differences between the standard 5/8″ thick boards and the more robust 3/4″ boards.


5/8″ Western Red Cedar Fence Boards

Pros

More Affordable – One of the primary reasons homeowners and contractors opt for 5/8″ fence boards is the cost savings. These boards are typically more budget-friendly than 3/4″ boards while still offering many benefits of western red cedar.

Lightweight and Easier to Install – Because they are thinner, 5/8″ boards are lighter, making them easier to transport and install. This can be particularly beneficial for DIY projects where handling heavy materials might be a concern.

Aesthetic Appeal – 5/8″ boards still maintain the rich natural grain and color of western red cedar, providing an attractive fence that enhances curb appeal. They are available in a variety of grades, so you can choose a quality that fits your budget and design preferences.

Sufficient for Many Applications – If the fence is primarily for aesthetic purposes or light-duty privacy, 5/8″ boards provide a good balance of durability and cost-effectiveness.

Cons

Less Durable Over Time – The thinner profile of 5/8″ boards makes them more susceptible to warping, cupping, and splitting, especially in extreme weather conditions. Over time, they may require more maintenance to maintain their structural integrity.

More Prone to Gaps and Shrinkage – Wood naturally expands and contracts with changes in humidity and temperature. Thinner boards are more prone to shrinking, which can create small gaps in the fence over time.

Lower Resistance to Impact and Strong Winds – If you live in an area with high winds or frequent storms, 5/8″ boards may not hold up as well as thicker boards. They are more likely to flex and may break under extreme conditions.


3/4″ Western Red Cedar Fence Boards

Pros

Superior Durability and Strength – The extra thickness provides better resistance to warping, cupping, and cracking. This results in a longer lifespan and reduced maintenance over time.

Better Wind and Impact Resistance – Thicker boards offer greater structural integrity, making them a superior choice in regions prone to high winds, storms, or other harsh environmental factors.

Improved Longevity – With proper installation and maintenance, 3/4″ cedar fence boards will last longer than their thinner counterparts, making them a better long-term investment.

More Luxurious and Substantial Appearance – The added thickness gives the fence a more premium, sturdy look, which enhances the overall aesthetic appeal and perceived value of your property.

Cons

Higher Cost – The primary drawback of 3/4″ boards is the increased cost. The extra material means a higher price per board, which can add up quickly for larger fencing projects.

Heavier and More Labor-Intensive Installation – The additional weight makes these boards more difficult to handle, requiring more effort and sometimes additional support for proper installation. This can increase labor costs if hiring a contractor.

Limited Availability in Some Regions – While 5/8″ boards are widely available, 3/4″ boards may not be stocked in all lumber yards, requiring special orders or sourcing from specialty suppliers.


Which Thickness is Right for Your Project?

The decision between 5/8″ and 3/4″ western red cedar fence boards depends on several factors, including your budget, climate, intended fence lifespan, and aesthetic preferences.

Choose 5/8″ If:

  • You are looking for a more budget-friendly fencing option.
  • The fence is for decorative purposes or light-duty privacy.
  • You live in a moderate climate with minimal exposure to harsh elements.
  • You want a lightweight material that is easier to install.

Choose 3/4″ If:

  • You want a fence with maximum durability and longevity.
  • You live in an area with high winds, storms, or other harsh conditions.
  • You are willing to invest in a premium, longer-lasting fence.
  • A more substantial and luxurious aesthetic is a priority.

Western Red Cedar Fence Board Grades

Day after day, we receive inquiries for the price of fence boards. Unlike traditional lumber yards and box home improvement stores, when a call like that is received at our shop, our staff provides a price for a Western Red Cedar fence board as well as the grade. In many cases, the person who is inquiring about the price does not have a clear understanding of what the grading means and may compare pricing of products from various sources that are not equal.

Imagine calling around to different restaurants and asking for the price of “cheeseburger”.  While it is called the same thing at a fast-food restaurant, as well as at a nice family restaurant, the “cheeseburger” at each location will be of different quality, and the pricing would reflect that. You would not purchase a cheeseburger based solely on price while not taking into consideration the quality, so therefore, you should not select a fence board based strictly on price either.

While there is no regulation or standards for “cheeseburgers”, there are established standards for fence boards that have been developed by the National Lumber Grades Authority, as well as the West Coast Lumber Inspection Bureau. It is important to note that “fence grade” is below knotty or clear grades of Western Red Cedar and should not be compared to the quality or held at the same standard as lumber in those grades.

The West Coast Lumber Inspection Bureau divides Western Red Cedar Fence Boards into three basic categories. Any grade may be rough or surfaced, Air Dried, Kiln Dried or “green”. Grade is determined by the best face.

No. 1 Fencing “Select”

  • Checks and Pinholes are not limited
  • Shakes are “Fine”
  • Skips are “hit and miss”, splits are “short”
  • Knots are sound and tight
  • Spike Knots can be approximately 1/2 face width or equivalent
  • Tolerance of 1/16″ over or under in thickness, width may vary along the piece of 1/8″, but not to exceed 20% of the pieces

No. 2 Fencing “Quality”

  • Checks and Pinholes are not limited
  • Shakes are “fine”
  • Skips are “hit and miss”, splits are “medium”
  • Wane can be 1/2 thickness as well as 1/3 width
  • There can be small spots or streaks of unsound wood
  • White speck not limited
  • There may be some knots that are not firmly fixed or are unsound but may not exceed 1/3 the width of the board
  • Spike Knots can be 3/4 of the face width
  • Maximum 1″ holes with 4 per foot allowed, unless “No Hole” is specified
  • Same tolerance of thickness and width as Select Fencing

This is a great example of our No. 2 Select “No Hole” Fencing, which is the standard fence board we supply unless otherwise specified. This particular fence is made from 3/4″ net thick material that the customer made a custom, decorative top cut to.

No. 3 Fencing “Rustic”

  • Lumber of this grade is suitable for low grade and permits all characteristics which do not interfere with the use of the piece
  • Thickness can be 3/16″ over or under invoiced thickness
  • Edge skips can not exceed 1/4″
  • Variation on width should not exceed 1/2″

We do not generally carry any No. 3 fencing or any fencing that allows for holes. On the off chance we have some, or order this product in for a particular order, we do not allow returns or exchanges on ANY No. 3 fencing, as the pricing reflects the quality of the material of the whole order.

  • “Light” or “Fine” Shake is not over 1/32″ wide
  • “Medium” Shake is not over 1/8″ wide
  • “Surface” Shake occurs on only one surface of the piece
  • Shake should not be confused with bark seams

Split – A separation of the wood through the piece of the opposite surface or to an adjoining surface due to the tearing apart of the wood cells.

  • “Very Short” is equal in length to 1/2 of the width of the piece
  • “Short” is equal in length to the width of the piece and does not exceed 1/6 the length
  • “Medium” is equal in length to twice the width of the piece and does not exceed 1/6 the length
  • “Long” is longer than a medium
