Building a wooden fence can be a great addition to your property. Not only does it provide privacy and security, but it also adds an aesthetic appeal to your yard. However, before you start building, it's essential to understand the different parts that make up a wood fence.

From posts and rails to pickets and caps, each component serves a specific purpose in creating a sturdy and attractive fence. Whether you're planning on building your own fence or hiring a contractor, this guide will provide valuable information about the various parts of a wooden fence so that you can make informed decisions about the design and construction of your project. Understanding the role of each fence part can also help you when budgeting for your fence project. So let's dive in!

Parts of a Wood Fence

A well-built wood fence can last for decades if properly maintained. However, before you start building your own wood fence or opt for professional fence installation, it's important to understand the different parts of a wood fence. This will help you plan and design your fence project more effectively.

Typically, a residential wood fence consists of three key parts: sturdy posts, pickets or in-fill boards, and rails. These components work together to create a beautiful and functional barrier around your property.

Wooden Fence Posts

Wooden fence posts are essentially vertical structural members of a fence that provide support and stability to the overall structure. These posts are usually made from various types of wood, such as cedar or pine, and are designed to be driven into the ground at regular intervals along the length of a fence line.

The dimensions of wooden fence posts can vary depending on the intended application and the type of fence they will support. Typically, these posts measure between 4 and 6 inches in diameter and are installed at intervals ranging from 6 to 10 feet apart.

The process of selecting the appropriate wood type for a given application involves careful consideration of factors such as climate conditions, soil composition, and expected lifespan. Proper installation techniques are crucial in ensuring that these posts remain strong and durable over time.

Wooden posts need regular maintenance to prevent rotting or decay that can compromise the integrity of the fence structure over time. With proper care and attention, wooden fence posts can provide a lasting and reliable solution for your fencing needs.

Pickets or Boards

Wooden fence panels or fence pickets, also known as slats or boards, are a timeless symbol of the American dream. From the iconic white picket fences in suburban towns to the rustic wooden boards of rural homesteads, these fence boards mark boundaries and create a sense of home.

Wooden pickets come in various sizes and thickness levels, allowing for customization and flexibility in fence design. Commonly, they are available in heights of 4 feet or 6 feet and thicknesses of 3/4 inch or 1/2 inch. The selection of the appropriate size depends on the desired level of privacy, the overall fence design, and the surrounding landscape.

The thickness of the pickets is also a factor to consider, with 3/4 inch pickets being more robust and providing a sturdier fence, while 1/2 inch pickets are often chosen for more budget-friendly options.

The arrangement of pickets in a wood fence allows homeowners to customize their level of privacy and the overall aesthetic appeal of their yard. For those seeking complete privacy, tightly placing pickets side by side is the ideal option. This arrangement leaves no gaps for onlookers to peer into the yard, creating a solid barrier that ensures maximum privacy. However, if you prefer a fence design that balances privacy and sunlight, a shadowbox arrangement is worth considering.

Supporting Rails

Supporting rails are an essential component of wood fences, providing structural stability and support to the pickets or boards. Typically running horizontally between the fence posts, these rails play a crucial role in holding the fence together and preventing sagging or warping over time.

Supporting rails are usually made from a durable wood such as pressure-treated lumber or cedar to withstand outdoor conditions and resist decay. The number of rails used in a fence can vary depending on the fence height and design. Commonly, a wood fence will have two or three rails, evenly spaced between the top and bottom.

The rails are attached to the fence posts using fasteners such as screws or nails. They serve as a framework for the pickets or boards, providing a secure attachment point and distributing the weight of the fence evenly. Proper installation and spacing of the supporting rails are crucial for maintaining the structural integrity of the fence and ensuring its longevity.

In addition to their functional role, supporting rails also contribute to the overall aesthetic appeal of the wood fence. They create clean, horizontal lines that complement the vertical pickets or boards, resulting in a visually pleasing design.

Additional Wood Fence Components

In addition to the primary components of a wood fence like posts, pickets or boards, and supporting rails, several other parts contribute to both the function and style of a wooden fence. These additional components enhance the fence's overall appearance, security, and longevity. Here are some of them

Post Caps

Post caps are decorative elements that are placed on top of fence posts. They serve both functional and aesthetic purposes. Functionally, post caps help protect the exposed end grain of the post from moisture, preventing rot and extending the lifespan of the fence. Aesthetically, they add a finishing touch to the fence, enhancing its overall appearance.

Post caps come in various designs, materials, and sizes to match different fence styles. Common materials include wood, metal, vinyl, or composite. They can be simple and classic, such as flat or pyramid-shaped caps, or more ornamental with intricate designs or decorative finials. Some post caps also feature built-in solar-powered lights, providing illumination to the surrounding area at night.

Cap Board

A cap board, also known as a top rail or a cap rail, is typically installed on top of the supporting rails, running horizontally along the uppermost part of the fence. It helps protect the exposed ends of the pickets or boards, preventing water infiltration and prolonging the life of the fence. Covering the top edges of the pickets or boards, it also adds a cohesive and polished appearance to the fence.

Cap boards can be made from the same material as the pickets or boards, ensuring a seamless and uniform look. Alternatively, they can be   crafted from a different type of wood or even a composite material for added durability and visual contrast. Commonly, cap boards are wider than the pickets, creating a visually appealing accent that adds character to the fence.


A kickboard, also known as a mud board or a baseboard, is a horizontal board that is installed at the bottom of a wood fence, usually between the ground and the first picket or board. The primary function of a kickboard is to protect against ground-level moisture, preventing the lower portion of the fence from rotting or decaying over time. By creating a barrier between the soil and the fence, it helps to extend the lifespan of the fence and maintain its structural integrity.

While not always necessary, incorporating a kickboard into a wood fence can provide added durability and protection, especially in environments where moisture exposure is a concern. It can help extend the lifespan of the fence and maintain its structural integrity over time.


A trim board, also known as a fascia board or a decorative board, is an additional element used in wood fences. It adds a finished look to the fence and can protect it from damage caused by insects, moisture, or weathering. The trim board is also used to cover visible hardware on a fence, such as screws, hinges, and other fasteners. This can help keep the appearance of the fence uniform and give it a more polished look.

When selecting trim boards, it's important to consider the material's durability, resistance to weathering, and compatibility with the rest of the fence components. Common materials for trim boards include wood, vinyl, or composite. Choosing the right trim board can enhance the overall aesthetic appeal and provide a cohesive and visually appealing finish to your wood fence.

Fence Gates

Fence gates are essential components of any fence, providing entry and exit points for both people and vehicles. They offer convenience, security, and functionality to a property, allowing for controlled access and protection of the enclosed area.

The design of a fence gate can vary, ranging from a simple single-panel gate to double gates or sliding gates for wider openings. Some fence gates feature decorative elements, such as arched tops, lattice patterns, or ornamental hardware, to enhance the visual appeal and complement the overall fence design.

Fence gates are not only functional components but also add to the curb appeal and value of a property. Whether it's a decorative garden gate or a sturdy driveway gate, choosing the right fence gate can enhance the accessibility, security, and overall aesthetic of your fenced area.

Frequently Asked Questions

What are the bars on a fence called?

The bars on a fence are typically called "rails." These horizontal components are responsible for providing structural support to the fence and connecting the posts. Rails can be made of wood, metal, or other materials, and their number and spacing vary depending on the fence design. They play a crucial role in maintaining the stability and integrity of the fence, ensuring it withstands external forces and remains secure.

What is the pointy part of a fence called?

The pointy part of a fence can vary depending on the type of fence. In some cases, they may be referred to as "finials" or "spears," which are decorative ornaments or pointed elements placed on top of fence posts or pickets. But in the context of a wood fence, the pointy parts are probably fence pickets. The pointed or tapered shape of pickets makes it more difficult for individuals to climb over the fence. They also contribute to the classic, timeless look that many homeowners associate with a wood fence.

What are the vertical parts of a fence called?

The vertical parts of a fence are commonly referred to as "posts." Fence posts are the vertical structural components that are set into the ground to support and anchor the fence. Fence posts are typically made of wood, metal, or concrete, and their size and spacing depend on the specific fence design and material used. They play a critical role in maintaining the overall integrity and strength of the fence. The vertical parts can also be "pickets" or "boards."
