Wainscoting Calculator

Your details

Shadow box adds a raised rectangular frame on a flat backer. Board and batten uses vertical battens spaced across a horizontal backing board.
Choose whether you want the calculator to find the right number of panels from your desired width, or divide the wall by a fixed panel count.
Measure the total horizontal length of the wall (or run of walls) to be panelled.
in
Height from the floor to the top of the cap moulding. Typical range is 32 to 48 inches (81 to 122 cm).
in
Ideal panel opening width. The calculator finds the nearest whole number of panels that comes closest to this width.
in
Width of each vertical frame member (stile) or batten. Typically 2 to 3.5 inches (5 to 9 cm).
in
Height of the horizontal rail at the top of the panel opening (below the cap moulding).
in
Height of the horizontal rail at the bottom of the panel opening (above the baseboard).
in
Height of the baseboard at the base of the wall. Baseboard material is listed separately in the take-off.

Standard interior doors are assumed to be 32 in (81 cm) wide for deduction purposes.
Width of each door opening to deduct from usable wall length.
in
Standard windows are assumed to be 36 in (91 cm) wide for deduction purposes.
Width of each window opening to deduct from usable wall length.

7 panels at 17.71 in wide each

  • Your 144.0 in wall fits 7 panels, each 17.71 in wide by 25.50 in tall.
  • The panel proportions fall in the classic portrait ratio (roughly 1:2 to 3:4), which gives a traditional, elegant look.
  • Total material needed (with waste allowance): 76.6 linear ft.
  • Estimated material cost: $191.58 USD based on your entered price per linear foot.

Next stepAdd a 10% buffer to your panel and stile order for on-site cuts and any pieces with grain or colour mismatch.
