What We Do
FreeBoardAndBatten.com is a free set of planning tools designed to take the guesswork out of board and batten wall installations. Whether you're tackling a single accent wall, a full room, exterior siding, or wainscoting, our calculators give you the exact numbers you need before you pick up a saw.
Every tool on this site is free to use with no account, no login, and no paywall. Enter your measurements, get your layout — that's it.
Our Tools
We offer purpose-built calculators for every stage of a board and batten project:
- Board & Batten Calculator — the full planning tool: spacing, installation marks, cut list, stock optimization, material quantities, and cost estimate in one place.
- Spacing Calculator — focused on finding the right batten spacing for your wall width and batten count.
- Material Calculator — generates a complete cut list and stock optimization plan to minimize waste.
- Cost Calculator — estimates lumber and material costs based on your layout.
- Wainscoting Calculator — the same full calculator configured for half-wall (wainscoting) installations.
How It Works
Our calculation engine runs entirely in your browser. Your project data never leaves your device — there are no servers storing your measurements, no accounts to manage, and no data to protect beyond your own browser session.
The engine computes batten positions from the wall origin to prevent rounding drift, handles openings (doors, windows, fireplaces) as real span constraints, and applies First Fit Decreasing bin packing to minimize stock board waste. Results are planning estimates — always verify field measurements before cutting material.
Our Guides
Beyond the calculators, we publish in-depth guides on board and batten spacing, measurement, siding, installation, design ideas, and cost. These are designed to give you the context behind the numbers so you understand why a layout works, not just what the calculator outputs.
