Wainscoting Calculator
Estimate wainscoting panels and trim linear feet.
Estimate wainscoting by the linear foot at panel height. Measure the covered perimeter, subtract doorways, and divide by the panel width to calculate the panel count. Standard heights are 32–36 inches for chair rails or 48 inches. Add rail, stile, and cap trim equal to the run, plus 10% for waste. Enter the wall run to calculate panels and trim.

How does the wainscoting calculator work?
Panels = (room perimeter in inches ÷ panel width). Chair rail and base run the full perimeter, with 10% added for cuts.
What else do people ask about this calculator?
How tall should wainscoting be?
1/3 of ceiling height is a classic rule — usually 32–36 in for 8 ft ceilings, up to 60 in for tall rooms.
How much do I subtract for doors?
Subtract each door width from the perimeter for panel count; chair rail and base still run under trim.
