Striped wallpaper can be bold or understated depending upon the colors and widths of the pattern. For a modern approach, position the wallpaper horizontally to visually expand the width of the walls. Vertical stripes offer a more traditional approach, but can be coordinated with a variety of styles. Tone-on-tone striped wallpaper is less prominent. For example, a white stripe alternated with a shimmery silver one can be very subtle. A striped pattern with highly contrasting tones such as black and white has a more dramatic effect in your room.
A primary concern of adding striped wallpaper to a room involves how to coordinate it with other elements in the room. Rooms with very little pattern in them to begin with might benefit by adding striped wallpaper. Color-coordinate striped wallpaper with other patterns such as florals or other stripes. For balanced contrast, consider a wide stripe when there are other small patterns in the room. Use a narrow stripe in a room with a large-scale pattern elsewhere, such as on a rug or on fabric. With multiple patterns, consider applying wallpaper with a color pulled from the room on just one accent wall for a subtle finishing touch. For instance, use yellow and white-striped wallpaper in a room that has floral curtains with yellow as the dominant color.
Stripes act as a strong visual texture for a room. Solid painted or metal furniture acts as a counterpoint to the wall pattern. Reflective pieces such as mirrors or mirrored furniture duplicate the pattern in the room. Furniture or fabric that has a similar tone to one of the wallpaper colors blends and unifies the space. Stripes offer a strong backdrop for bold, solid colored fabric such as wool or leather.
Unless you have experience hanging wallpaper, it is best left to the professionals, especially when it involves a pattern. If you are determined to try it yourself, buy a sample of your chosen design and do a test in an inconspicuous area or use a wood board as a sample wall. Stripes may seem easier than other patterns because the lines allow for a straight edge, but if you are unsure, consider saving yourself the time by hiring a professional so that you can enjoy the results.
