How we verify our calculatorsSpace boards 1/8 inch apart behind each batten to allow for wood expansion. Cedar and pine move significantly with humidity changes.
Use 1x8 boards with 1x2 battens for the classic look. Wider boards (1x10 or 1x12) create a more modern, farmhouse feel.
Calculate your board feet for lumber pricing with our board foot calculator when buying rough-sawn lumber for custom milling.
Pre-prime all six sides of wood boards before installation. Back-priming prevents moisture absorption and cupping that causes boards to pull away from the wall.
For exterior applications, use stainless steel or hot-dipped galvanized nails. Regular nails rust and leave black streaks down the siding within a year.
Fiber cement board and batten costs more but lasts 50+ years with zero rot. It is the best long-term value for exterior siding in wet climates.

Formulas
Pattern Width = Board Width + Batten Width
Boards = ceil(Wall Length / Pattern Width) + 1
Linear Feet = (Boards + Battens) x Wall Height
How wide should board and batten boards be?
6 to 12 inches is standard. 8-inch boards with 2-inch battens are the most popular classic look. Wider boards (10 to 12 inches) give a modern farmhouse feel.
What is the spacing between boards?
Boards are placed edge to edge (or 1/8 inch gap for wood expansion) with battens covering the seams. The batten is the spacer.
How much does board and batten cost?
$3 to $10 per linear foot installed for wood. Cedar runs $2 to $4/LF for material, pine $1 to $1.75/LF. Fiber cement costs $2.50 to $5/LF.
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?
Yes for exterior siding over sheathing. 1x3 furring strips create a rain screen gap that prevents moisture damage. Not needed for interior applications.
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 the best natural wood (25+ year lifespan). Pine needs paint and lasts 15 to 20 years. Fiber cement is the most durable at 50+ years.
A single living room accent wall. Budget $592 to $1,184 for cedar materials.
Half-height wainscoting around a bedroom perimeter. Budget $460 to $805 for pine.
One side of a detached garage. Fiber cement lasts 50+ years. Budget $1,725 to $3,450.
Total exterior perimeter of a mid-size home. Budget $8,262 to $16,524 for cedar.
Not back-priming wood boards
Moisture warps and cups unprimed backs. Pre-prime all six sides before installation to prevent boards from pulling away from the wall within the first year.
Using regular nails on exterior
Standard nails rust and leave black streaks down the siding within one year. Use stainless steel or hot-dipped galvanized fasteners for any exterior application.
Forgetting expansion gaps behind battens
Wood expands with humidity. Leave 1/8 inch between boards behind each batten. Without gaps, boards buckle outward in summer heat.
Not accounting for windows and doors
Deduct window and door openings before calculating total board count. Over-ordering by 20%+ wastes hundreds of dollars on large projects.
Mixing board widths from different batches
A nominal 1x8 varies by up to 1/16 inch between mills and batches. Buy all boards from the same supplier and lot for consistent spacing.
