Calculate Wainscoting

For the Wainscoting Calculator, enter total wall run, wainscot height, waste allowance, material price, and coverage per unit. It separates measured area from allowance-adjusted order area, then reports square yards, package count, and optional material cost.

Formula used

Area = length × width; order area = area × (1 + waste ÷ 100); square yards = order area ÷ 9

Worked wainscoting example

Wainscoting Calculator example: 25.9 ft × 3.2 ft = 82.88 ft². With 10% allowance the order area is 91.17 ft², equal to 10.13 yd².

Turn area into a material list

Use the square-foot result for field panels, but prepare separate linear-foot counts for rails, stiles, cap, shoe, and corner trim.

Layout details outside the area formula

Panel module, stile and rail widths, inside and outside corners, cap and base trim, outlets, and pattern centering affect material use.

Questions specific to this calculation

Does the area result include rails, stiles, cap, and base trim?

Use total wall run as the first dimension and installed wainscot height as the second, then remove large openings only when the layout truly omits them.
