The movement of hardwood flooring is driven by changes in moisture content. When wood gains or loses moisture, it expands and contracts. Because this change happens across the width of the board rather than the length, wider planks experience a greater total amount of change than narrower ones. For example, a 7-inch wide plank will show a wider gap between boards during a dry winter than a 3-inch wide plank, simply due to the accumulation of movement across the surface area of the floor. NWFA guidelines emphasize the importance of stable environments when choosing wider widths, particularly for solid flooring. Proper acclimation is crucial; the flooring must be at the correct moisture content relative to the subfloor before installation begins. For wider planks, engineered construction is often recommended because it provides the visual beauty of the wide format while utilizing a core structure that significantly resists the expansion and contraction that would typically plague a solid wide-plank floor.
