Ready for trim?

Provide your wall length and desired number of panels to see the cut dimensions for each section.

Overview

Symmetry is the most important factor in a professional wainscoting installation. The challenge lies in distributing the vertical 'stiles' (trim pieces) so that every decorative panel is exactly the same width. This calculator subtracts the combined width of all vertical stiles from the wall length and divides the remainder equally among your panels.

Pro Tips

In metric regions, 90mm is a common width for MDF stiles, which is very close to the standard US 3.5-inch width.
If your panel width comes out too narrow (less than 12 inches), consider reducing the panel count by one for a cleaner look.
Remember to account for corner baseboard depth if you are running the stiles all the way to a corner.

Fun Facts

"Traditional wainscoting usually rises to roughly 1/3 the height of the wall (approx 32-36 inches)."
"The 'stile' is the vertical member of the frame, while the 'rail' refers to the horizontal top and bottom pieces."
"Odd numbers of panels (3, 5, or 7) are often preferred by interior designers for a more natural visual balance on shorter walls."

Formula: Panel Width = [Wall Length - (Stile Width × (Panels + 1))] / Panels
