Wainscoting calculator with panel spacing and trim quantities
Estimate wainscoting proportions from wall size, panel count, stile width, and rail sizes. The tool calculates equal panel widths, trim quantities, and draws the full layout so you can check the balance before installation.
Equal-width panel layout
Set the wall length, panel count, and stile width to calculate evenly spaced panel widths across the wall.
Rails and stile quantities
The tool estimates each stile length, top and bottom rail lengths, and total trim quantity with wastage.

See the wainscoting arrangement drawn on the wall so you can judge the proportions before you cut or quote.
Estimate panel widths, rails, stiles, and trim length
This first version is focused on clean equal-width panel layouts across a single wall. It gives you a quick diagram, trim quantities, and proportion checks in metric or imperial.
