First ensure there is plenty of room by removing all the furniture in the room. Scour the bottom and top edges of the chair with a utility knife. Ensure that you work below the chair-rail line to ensure they are not covered by wainscoting. Scrape the old wallpaper that is underneath the chair rail. Ensure that you figure out the vertical framing and spacing for the panels. In addition, put into consideration the room outlets.

Furthermore, you should take the height of one dining room chair in the room. Ensure that you establish how far off the chair rail should be. Mark the wall in one position and use a level to mark up the rest of the room. Determine the size of the panels by measuring the lengths of the walls. Ensure that you mark the vertical lines by using a level to keep the level.
