Beadboard is a row of narrow wood planks lined up vertically. In between each wood plank is a little indentation or ridge–also known as a “bead”. These days most ‘beadboard’ comes in long, monolithic sheets that are easy to install and imitate the look of narrow vertical planks. Beadboard comes about 1/3 up the sides of the wall, with the chair rail at the top and the baseboard at the bottom.
