Chair rail molding is easy to install, and there are many styles to choose from. There are plenty of modern, simple, and inexpensive chair rail ideas for all rooms of the house, from bedrooms and stairways to hallways and kitchens. For example, chair rail tile trim (often called pencil tile) in a bathroom often offers a clean divide for a tile and wallpapered wall. 

Chair rail can be added to any room. Below, find considerations to keep in mind and instructions to install chair rail in your home.

Purpose of Chair Rail

Chair rail moldings installed along the walls first came into use as a buffer to prevent the backs of chairs from hitting delicate plaster walls in dining rooms, where chairs were constantly being moved back and forth around the table. As plaster walls turned into wallboard and formal dining rooms lost their popularity, so too did chair rails. But now the chair rail, along with other traditional types of ornamental trim, such as wainscoting, tall baseboards, and crown molding, has surged back into homes as a desirable design element. 

Difference Between Chair Rail and Wainscoting

Wainscoting is paneling that goes on a wall. Chair rail is the trim that is placed on the top edge of wainscoting to give it a finished look. However, chair rail can be installed on a wall without wainscoting.

How High Up Should Chair Rail Be?

Chair rail molding is typically installed between 30 and 48 inches from the floor. Installation at this height (or higher) will be decorative but it can also serve its traditional function to protect the walls from the backs of dining room chairs.

If you prefer to place the chair railing where it will protect the walls from the back of the chairs, simply measure the height of the chair backs and position the chair rail molding at this height. Otherwise, consider these specific heights depending on your room's ceiling height:

  • 8-foot tall ceiling: Place chair railing between 32 and 36 inches up from the floor.
  • 10- to 12-foot tall ceiling: A room with high ceilings can accommodate a chair rail that is between 40 and 48 inches up from the floor.

Pairing Chair Rail With Wainscoting

It's popular to use chair rail as a top finishing edge for wainscoting. Traditionally, wainscoting was made from wood panels set within moldings. But in the modern form, it often takes the form of "faux wainscoting," in which vertical lengths of molding are attached to the wall from the chair rail to the baseboard to create the look of panels.

This entire bottom section of the wall can be painted a different color to create the look of a solid wainscot, or the faux panels within the molding outlines can be painted a different color to contrast with the moldings. Any rough edges where the vertical lengths of molding butt against the chair rail and baseboard can be smoothed over with caulk or wood putty. 

How to Install Chair Rail

A chair rail is the ultimate DIY project since few tools are needed and almost anybody can do it. This is a project that provides a lot of satisfaction for a modest investment in time and materials. Even though chair rail molding can be fairly pricy, you won't be using a lot of it.

Tip

Consider painting your chair rail molding before attaching the pieces to the wall. This can be much easier than trying to paint a chair rail after it is attached.

What You'll Need

Equipment / Tools

  • Tape measure
  • Chalk line
  • Pencil
  • Stud finder
  • Circular saw
  • Coping saw
  • Power nailer with long brads, or hammer and finish nails
  • Drill and 1/16-inch twist bit (if necessary)
  • Hammer and nail set (if you are using finish nails)

Materials

  • Chair rail molding
  • Wood putty (if necessary)

Instructions

  1. Mark the Wall

    • Mark the wall at one end to indicate the top of the chair rail molding. Normally, this will be between 32 and 36 inches above the floor in a typical room with an 8-foot high ceiling.
    • Make an identical mark at the opposite end of the wall. 

  2. Snap a Chalk Line

    Snap a chalk line between the two marks to make a reference line to indicate where the top of the chair rail molding will fit. 

  3. Check for Studs

    • Use an electronic stud finder to find the positions of the vertical wall studs where they intersect the chalk reference line.
    • Mark the line at these points, using a pencil. In most cases, the studs will be spaced 16 inches apart, measured on-center. 

  4. Cut Molding

    • Cut a length of chair railing molding to fit across the first wall. If possible, use a single length of molding to cover the entire length of the wall 
    • If two pieces are necessary, use a scarf joint—a joint where the ends are angled at 45 degrees—where the two pieces meet in the center.
    • The ends of the molding should be cut square at 90 degrees to fit tightly against the adjoining walls of the room. 

  5. Attach Molding to Wall

    • Nail this first piece of molding to the wall, driving brads or finish nails into the wall at the stud locations.
    • If you are driving finish nails with a hammer, use a nail set to recess the nail heads slightly below the surface of the wood. A cordless finish nailer can make quick work of this task.
    • Thin pieces of chair rail, especially if they are hardwood, may benefit from drilling pilot holes for the nails to avoid splitting the wood. 

  6. Repeat on Next Wall

    • Repeat steps 1 to 3 on the wall on either side of the first wall. 
    • For the end that meets the already installed piece, cut the molding at a contour to match the profile of the adjoining moldings, using a coping saw. These joints are known as coped joints, which are tighter and provide a more professional look than angled miter joints. 

  7. Repeat on Remaining Walls

    On the remaining two walls, repeat the entire process. The final piece will need a coped joint on each end.

  8. Fill Nail Holes

    Use wood putty to fill any nail holes in the molding. 

FAQ
  • Does chair rail add value to a home?

    Chair rail is a classic design element and an elegant architectural detail. When added, this small touch can increase the value of your home.

  • What can I use instead of chair rail?

    If you love the look of chair rail, but don't want to permanently install it, use an alternative, such as peel-and-stick decals that can include the look of wainscoting with chair rail. You can also look for actual peel-and-stick chair rail that goes on the wall with adhesive instead of nailing it on.

  • How do you modernize a chair rail?

    Designers often put modern wallpaper above a chair rail to freshen up a room. For an even more modern appearance, add flattened wood trim in place of traditional rounded chair rail trim.

  • Does chair rail have to match the baseboard?

    Matching the color of your chair rail to the baseboard will give your room a more unified look.

  • Should a lighter or darker color go above or below a chair rail?

    Most people paint the wall above the chair rail a different color than what's below. Here's a good rule of thumb when choosing paint colors: Use a darker color below the chair rail to ground the room and a lighter color above the chair rail to highlight the space. If you have dark furniture, you may want to paint the bottom a lighter color, or white, and the top of the rail a shade or two darker (but not too dark).
