Board and Batten: A Scandinavian Idea, a Modern Farmhouse Obsession
Board-and-batten siding is one of the oldest exterior cladding techniques in continuous use. The pattern — wide vertical boards laid edge to edge, with narrow battens nailed over every joint to shed water — shows up on Norwegian stave churches from the 12th century, on Swedish barns painted Falu red, and on early American agricultural buildings from Pennsylvania to Tennessee. It made sense in places where sawmills cut wide planks but pre-fabricated lap siding wasn't yet available; you simply ripped boards to whatever width your tree produced, butted them up, and capped the joints. The result was cheap, weather-tight, easy to repair plank by plank, and visually striking from a hundred yards across an open field.
The technique nearly disappeared in the postwar US suburbs as vinyl and aluminum lap took over, surviving mainly on outbuildings and historic restorations. Then came the modern farmhouse revival of the mid-2010s. HGTV's Fixer Upper, Joanna Gaines's design vocabulary, and a generational appetite for an exterior that felt like the inside of a Brooklyn coffee shop — white, vertical, intentional — turned board and batten into the single most-requested siding pattern on new American homes. Walk through any new-construction neighborhood from Texas to Tennessee to Minnesota and you'll see white LP SmartSide or James Hardie board-and-batten on at least one elevation of half the homes. The cycle is now broadening into "modern moody" — the same vertical rhythm, but in deep black, charcoal, hunter green, and even cedar stained dark for a Scandinavian throwback that closes a 900-year loop on where the style began.
Whether you're cladding a 12-foot shed or a 4,000 sq ft modern farmhouse facade, the material math is the same: count the boards that fit across the wall length (wall length ÷ board width, rounded up), add one batten per board joint plus one at each end, multiply by wall height for linear feet, and add 10% for waste. This calculator does that automatically across multiple walls with door and window cutouts, then translates the linear feet into actual purchased board pieces at 8, 10, 12, 14 or 16 ft lengths and prices them by material — cedar, pine, cypress, redwood, LP SmartSide, or James Hardie fiber cement.
