Wainscoting Calculator
Wainscoting adds timeless elegance to any room while protecting walls from everyday wear. This calculator determines the panels, chair rail, and base cap molding you need based on your room perimeter, wainscoting height, and style preference, with automatic deductions for doors and windows.
The three main wainscoting styles have different material requirements. Beadboard uses 4x8-foot sheets of tongue-and-groove paneling cut to height. Raised panel wainscoting uses individual panel sections (typically 16-24 inches wide) set within a rail-and-stile frame. Flat panel (Shaker) uses MDF or plywood panels with applied molding strips.
Standard wainscoting height is 32-36 inches, roughly one-third of the wall height in a room with 8-foot ceilings. For rooms with 9 or 10-foot ceilings, 36-42 inches is more proportional. Chair rail molding caps the top edge and is both decorative and functional, protecting the wall where chair backs would contact it.
All styles require chair rail along the top and base molding along the bottom. Budget an extra 10% on trim pieces for miter cuts at corners and joints. For a DIY project, beadboard is the simplest to install, while raised panel wainscoting is best left to experienced carpenters or purchased as pre-made kits.
