Battens = With corners: Ceiling((Wall Width + Spacing) ÷ (Width + Spacing)), Without: Boards - 1
Total Material = (Boards + Battens) × Wall Height
Board and batten is a popular architectural siding and interior wall treatment that consists of wide boards placed side by side with narrow strips (battens) covering the seams between boards. This classic design creates a distinctive vertical pattern that adds texture, dimension, and visual interest to both exterior and interior walls. The board and batten calculator helps you accurately determine the amount of materials needed for your project, saving you time, money, and reducing waste.
Whether you're planning an exterior siding project, creating an accent wall, or adding character to a room with wainscoting, calculating the right amount of materials is crucial for a successful board and batten installation. Our calculator simplifies this process by providing precise measurements based on your specific project dimensions and design preferences.
Traditional board and batten construction typically uses wide wooden boards (ranging from 6 to 12 inches wide) with narrow battens (1 to 3 inches wide) covering the joints. However, modern applications have expanded to include various materials such as engineered wood, fiber cement, vinyl, and even metal, offering durability and lower maintenance alternatives to traditional wood.
The board and batten calculator uses several key formulas to determine the exact materials needed for your project. Understanding these calculations helps you plan your project more effectively and make informed decisions about material purchases.
The number of boards required depends on the width of your wall and the width of each board. The formula is:
For example, if you have a 10-foot (120-inch) wall and are using 8-inch wide boards:
The ceiling function ensures you always round up to the next whole number, as you can't purchase a partial board.
The number of battens depends on whether you're including corner battens and the spacing between battens. There are two common approaches:
When including battens at the corners of the wall, the formula is:
When battens are only placed between boards (not at corners), the formula is simpler:
The total linear feet of material needed combines the length of all boards and battens:
This calculation helps you determine how much raw material to purchase, especially when buying lumber by the linear foot.
To calculate the total square footage of material needed:
This calculation is particularly useful when purchasing sheet goods or when estimating paint or finish requirements.
In real-world applications, it's advisable to add a waste factor of 10-15% to your calculations to account for:

Board and batten is a versatile design element with numerous applications in both residential and commercial construction. Here are some common use cases:
Board and batten is a popular choice for exterior siding, particularly for:
For exterior applications, weather-resistant materials like cedar, redwood, fiber cement, or vinyl are recommended. The calculator helps determine the exact amount of materials needed to cover exterior walls, factoring in windows, doors, and other openings.
Board and batten accent walls add texture and visual interest to interior spaces, including:
For interior accent walls, materials like MDF (Medium-Density Fiberboard), pine, or poplar are commonly used due to their affordability and smooth finish. The calculator helps you determine the precise amount of materials needed for your specific wall dimensions.
Board and batten wainscoting is a popular wall treatment that typically covers the lower portion of a wall, usually 32-42 inches high. Common applications include:
When calculating materials for wainscoting, you'll need to adjust the wall height in the calculator to match your desired wainscoting height rather than the full wall height.
Board and batten techniques can also be applied to furniture and cabinetry projects:
For these smaller projects, the calculator can still be useful by entering the dimensions of each surface you plan to cover.
Board and batten is increasingly used in commercial settings for its aesthetic appeal:
The calculator helps commercial contractors accurately estimate materials for larger-scale projects, potentially saving significant costs.
While board and batten offers a distinctive look, there are several alternative wall treatments to consider:
Shiplap: Horizontal boards with rabbeted edges that overlap, creating a distinctive shadow line. Shiplap offers a more horizontal, coastal or farmhouse aesthetic compared to the vertical emphasis of board and batten.
Tongue and Groove: Interlocking boards that create a seamless, gap-free surface. This option provides a cleaner, more finished look than board and batten.
Beadboard: Narrow vertical boards with a rounded "bead" detail between each board. Beadboard offers a more traditional, cottage-like appearance with finer detailing than board and batten.
Panel Molding: Decorative frames created with applied molding, creating a more formal, traditional look than the rustic appeal of board and batten.
Brick or Stone Veneer: For a completely different texture and look, thin brick or stone veneers provide rustic character without the wood elements of board and batten.
Each alternative offers different aesthetic qualities, installation requirements, and cost considerations. Your choice should align with your overall design vision, budget, and maintenance preferences.
Board and batten construction has a rich history dating back centuries, evolving from practical necessity to a deliberate design choice.
The board and batten technique originated as a practical and economical building method in rural and agricultural settings. Its earliest documented use dates back to medieval European timber-frame construction, where it provided a simple solution for creating weather-resistant exterior walls.
In North America, board and batten became particularly prevalent during the 19th century. Early American settlers, facing the challenges of frontier life, adopted this straightforward construction method because:
Board and batten gained significant popularity during the Gothic Revival architectural movement of the mid-19th century. Architect Andrew Jackson Downing prominently featured board and batten in his influential 1850 book "The Architecture of Country Houses," promoting it as an appropriate style for rural cottages and churches.
This period saw the construction of numerous "Carpenter Gothic" churches and homes featuring board and batten siding, characterized by:
By the early 20th century, board and batten had fallen somewhat out of favor as mass-produced horizontal clapboard and later, manufactured siding materials became more economical. However, it remained popular in specific architectural styles:
Beginning in the late 20th century and accelerating in recent decades, board and batten has experienced a significant revival in both exterior and interior applications. This resurgence can be attributed to:
Today's board and batten applications often feature:
The enduring appeal of board and batten lies in its visual simplicity, textural interest, and adaptability to both traditional and contemporary design contexts.

59Board and batten siding is an exterior wall cladding style that uses wide vertical boards with narrow strips (battens) covering the seams between boards. This creates a distinctive pattern of alternating wide and narrow vertical elements, adding texture and visual interest to a building's exterior. It's commonly used in farmhouse, rustic, and some contemporary architectural styles.
To calculate board and batten materials, you need to:
The standard spacing between battens in board and batten construction typically ranges from 12 to 24 inches on center, with 16 inches being the most common spacing. However, this can vary based on aesthetic preferences and the specific look you're trying to achieve. Narrower spacing creates a more detailed, traditional appearance, while wider spacing offers a more contemporary look.
Board and batten refers to a construction method where wide boards are installed vertically with narrow battens covering the seams. Batten board (sometimes called "reverse board and batten") reverses this arrangement, with wide battens installed first and narrower boards covering the seams. The visual effect is similar but with different proportions and shadow lines.
For exterior board and batten, naturally rot-resistant woods like cedar, redwood, or cypress are ideal but expensive. More affordable options include pressure-treated pine, fir, or engineered wood products with proper sealing. For interior applications, pine, poplar, or MDF (Medium-Density Fiberboard) are popular choices due to their affordability and smooth finish for painting.
For exterior board and batten, boards should typically be 3/4" to 1" thick to provide adequate durability and weather resistance. For interior applications, 1/2" to 3/4" thickness is usually sufficient. Battens are typically 1/2" to 3/4" thick, regardless of whether they're used indoors or outdoors.
Yes, it's recommended to add a 10-15% waste factor to your calculated materials to account for cutting errors, material defects, complex cuts around windows and doors, and potential future repairs. For more complex projects with many corners or openings, consider using a 15-20% waste factor.
Yes, the board and batten calculator works equally well for interior accent walls. Simply enter the dimensions of your interior wall and your chosen board and batten specifications. For interior applications, you might typically use narrower boards and battens than for exterior siding.
To account for windows and doors:
Alternatively, you can calculate materials for the entire wall and then reduce by the approximate percentage of the wall taken up by openings, typically adding a slightly higher waste factor to account for the additional cuts needed around these features.
True board and batten uses individual boards with separate battens covering the seams. Faux board and batten often refers to techniques that create a similar look using plywood or sheet goods as the base layer with battens applied on top to create the appearance of separate boards. The faux method is often more economical and can provide better insulation but may not have the same authentic appearance as true board and batten.
The board and batten calculator is an essential tool for accurately estimating materials for your siding or interior wall project. By providing precise calculations based on your specific dimensions and design preferences, it helps eliminate guesswork, reduce waste, and ensure you purchase the right amount of materials.
Whether you're a DIY enthusiast tackling your first board and batten project or a professional contractor managing multiple installations, this calculator streamlines the planning process and helps you achieve professional results.
