How we verify our calculatorsPlan the Layout Before You Count Boards
A clean board and batten wall starts with the repeat spacing. Decide whether a board or batten should land on the center of windows, doors, or the room focal point, then adjust the starting edge before ordering material.
Pro Tips
Plan the pattern before buying material. Centering a batten or board on windows and doors usually looks cleaner than starting from one corner.
Use 1x8 boards with 1x2 battens for a classic look. Wider boards create a calmer, more modern wall.
Calculate your board feet for lumber pricing with our board foot calculator when buying rough-sawn lumber for custom milling.
For wood siding, follow the product or association installation guide for priming, back-priming, gaps, fasteners, and flashing details.
For exterior applications, use corrosion-resistant fasteners recommended for the material and local exposure.
Fiber cement and engineered systems have manufacturer-specific trim, flashing, clearance, and fastening rules. Check the install guide before ordering.
For standard lap siding options, our siding calculator estimates vinyl, fiber cement, and wood siding materials.
How the Calculator Works
Enter wall length and height in feet or meters.
Set board and batten widths, then choose your material type.
Get board count, batten count, linear feet, and total cost estimate.
Formulas
Base boards = ceil(wall length / board width)
Base battens = max(boards - 1, 0)
Linear feet = (boards + battens) x wall height x waste allowance

Common Questions
How wide should board and batten boards be?
6 to 12 inches is common. 8-inch boards with 2-inch battens give a classic pattern, while 10 to 12 inch boards make the wall feel quieter and more modern.
What is the spacing between boards?
For full-board board and batten, boards usually run across the wall and battens cover the seams. This calculator treats board width as the repeat spacing and then counts battens over the seams.
How much does board and batten cost?
Material cost varies by wood species, engineered product, trim, fasteners, waste, and finish. Use the cost range as an order-of-magnitude material estimate, then price your exact supplier list.
Can I use board and batten on interior walls?
Yes. It is a popular accent wall and wainscoting treatment. Use MDF or pine for interior. No weatherproofing needed, so material costs are lower.
Vertical or horizontal board and batten?
Vertical is traditional and sheds water better for exteriors. Horizontal works for interior accent walls but requires different framing support.
Do I need furring strips behind board and batten?
Some exterior assemblies use furring strips or rain-screen details, but requirements depend on cladding, sheathing, climate, and code. Follow the siding manufacturer's guide.
How do I handle corners with board and batten?
Use corner boards (1x4 or 1x6) at inside and outside corners. Cut boards to fit tight against the corner board. Do not wrap battens around corners.
What is the best wood for exterior board and batten?
Cedar is a common natural choice, while pine needs careful paint and maintenance. Fiber cement, engineered wood, and PVC products can be better when low maintenance matters.

Board and Batten Mistakes That Cost You Money
Starting from one corner without a layout
A full-width board may land awkwardly beside a window or door. Dry-layout the repeat and center the pattern on the most visible feature first.
Ignoring trim and openings
Windows, doors, corner boards, base trim, and cap trim change the order list. Count the wall field first, then add trim pieces separately.
Forgetting material movement
Wood, engineered wood, and PVC move differently. Follow the product guide for gaps, priming, fasteners, and clearances.
Using the wrong exterior fastener
Outdoor fasteners need to match the siding material and exposure. Use the fastener type recommended by the manufacturer.
Mixing board widths from different batches
Nominal boards can vary between suppliers and product runs. Buy enough from the same source before laying out a tight pattern.
