Each sheet is cut across into 2 strips 36 in high. Sheets are counted for full-width strips, so offcuts are not assumed usable.

This plans beadboard sheets ripped to height, plus the chair rail that caps it.

How it works

A 4 × 8 sheet is cut across into strips at your height. Sheets = wall length ÷ the run each sheet gives. Chair rail adds 10%.

Before you order

  • A height near one-third of the wall usually looks balanced.
  • Mark studs above the panel line for nailing the cap.
  • Keep cuts at the top so factory edges land at the floor or chair rail joints.

Common questions

How high should wainscoting be?

Around 32 to 36 in is common in 8 ft rooms, and taller in rooms with higher ceilings.

Why does 32 in cost less than 36 in?

A 32 in strip lets you get three strips from one 96 in sheet. At 36 in you only get two, so waste jumps.
