Which wainscoting styles would you recommend most for a narrow hallway?

For a narrow hallway, you need to make sure that the walls are not overdone. For this reason, raised panel or flat panel wainscoting would work well as they are not busy styles and will not make the hallway feel overwhelming. In terms of profiles, IN09 and CR22 can be used to create the wainscoting as they are both flat profiles, pair well together and can design many different interior styles.
