Wall trim serves both decorative and functional purposes in a home. It frames windows and doors, conceals rough edges and gaps, and adds aesthetic interest to plain walls. With so many options to choose from, selecting the right trim style and material for your home can be overwhelming. This guide covers the five most common types of wall trim and tips on how to choose the best option for your space.
Crown Molding
Crown molding is installed where the wall meets the ceiling. It is the most ornate and formal option for trim. Crown molding comes in different styles:
Traditional Crown Molding
This type of crown molding has an elegant, carved appearance. It works well in formal spaces like dining rooms, living rooms, and master bedrooms. Traditional crown molding looks best when crafted from solid wood. It comes in standard profiles like ogee and dentil.
Contemporary Crown Molding
For a more modern, streamlined look, opt for contemporary crown molding. It has simple, geometric shapes with clean lines. Contemporary crown pairs nicely with modern decor. It comes in materials like MDF, polyurethane, or polystyrene for flexibility during installation.
Coffered Crown Molding
Coffered crown molding attaches to a recessed panel in the ceiling. This creates a coffered or boxed structure. Coffered crown is great for giving a room visual height and dimension. It works well in larges spaces like great rooms.
When selecting crown molding, consider the architectural style of your home. Measure the room to calculate the required length. Determine the crown’s height and projection based on the ceiling height. Install crown molding at least 6 inches high to make an impact.
Chair Rail Trim
Chair rail trim runs horizontally at wainscot height around a room. Traditionally used in dining rooms, it protects walls from chair backs. Nowadays, it adds decorative flair to any space.
Traditional Chair Rail
Traditional chair rail has a classically simple design. Made of wood or polystyrene, it typically includes a cap rail, a panel molding, and a bottom rail. Opt for simple, elegant profiles like an oval bullnose.
Beaded Chair Rail
For a touch of texture, choose a beaded chair rail. Wood beads add interest along the top rail. This trim style blends well with shaker or arts and crafts decor. Use it to frame wainscoting or wall panels.
Decorative Chair Rail
Decorative chair rail incorporates ornamental elements for visual appeal. Look for designs with carved ridges, fluting, curves, or applied moldings. Decorative chair rail works well in elegant, formal spaces.
Make sure chair rail trim coordinates with the room’s interior architecture. Install it at 32-36 inches above the floor – chair back height. Use rail molding to frame walls with horizontal divisions.
Baseboard Trim
Baseboard trim runs along where the floor and wall meet. It gives a finished look to the lower part of walls. Baseboard trim also conceals imperfections and gaps between flooring and drywall.
Standard Baseboard
This economical option includes a simple board trim capped with a quarter-round or small molding. Standard baseboard comes in wood like pine or vinyl. Use it for subtle definition.
Architectural Baseboard
For a built-in look, use architectural trim baseboard. Made of dense polymer or MDF, it has detailed profiles reminiscent of carved wood. Architectural baseboard makes a statement.
Wall-Height Baseboard
Wall-height baseboard extends from floor to nearly the ceiling. At 6-9 inches tall, it makes rooms appear grounded and proportional. Wall-height base fits both modern and traditional styles.
Measure walls and openings when calculating linear footage for baseboard installation. Select a height and style that balances proportions. Use extra-tall baseboard in rooms with high ceilings.
Door and Window Casing
Door and window casings create an attractive frame that conceals rough edges around openings. Casing profiles complement base and crown trim.
Door Casing
A door’s casing refers to the interior trim that surrounds the frame. It includes corner blocks and sometimes a header. Look for wide, simple profiles or ornate molded designs.
Window Stool and Apron
The stool and apron form the bottom and interior sides of a window casing. Opt for a profiled apron that matches the baseboard. Add a stool for a finished sill.
Exterior Window Trim
Exterior casing encloses outer window frames. Structural brickmould trim also diverts water. Look for historically-styled casings like Craftsman or Victorian.
Select door and window casings to enhance your decor. Use stool, apron, and sill components to dress up windows. Install casing trim with care for a seamless look.
Panel Trim
Panel trim and moldings create framed sections on walls. Available styles range from shaker to raised panels. Use them to form accent walls or wainscoting.
Square Panel Trim
Square, recessed panel trim has a versatile, contemporary look. The flat center and outer lip create a framed effect on the wall. Opt for clean lines in vinyl, wood, or MDF.
Raised Panel Trim
For dimension, choose raised panel trims with a decorative center profile. The inner panel sits higher than the outer frame. Use raised panels sparingly to avoid busyness.
Beaded Panel Trim
Add texture with beaded paneling. Small, rounded beads create interest and depth on the inner panel. Beaded panels work well with cottage or arts and crafts decor.
Wainscoting Trim
Frame the lower third of walls in wainscoting. Install panel trim or decorative chair rail to form the look. Choose profiles that match your baseboards.
How to Choose the Right Trim for Your Home

- Opt for moisture-resistant materials like PVC or synthetic wood trims in damp places like bathrooms.
- Look for sustainable trims made using recyclable materials or production processes.
- Purchase trims primed or pre-finished to reduce labor time. Opt for durable finishes that resist yellowing.
- Work with experienced trim carpenters for proper installation. Use construction adhesive for durability.

Trim Installation Tips
Proper trim installation results in an integrated look. Here are some tips for installing trim successfully:
- Check all walls for straightness before installation. Correct any issues to prevent uneven gaps.
- Seal raw drywall edges with primer to reduce seam swelling when paint is applied.
- Use painter’s tape when cutting trim to avoid damage. Make scarf joints for seamless corners.
- Cut trim lengths at least 1.5 inches longer than measurements. Trim and fit them precisely for tight joints.
- Miter inside and outside corners at 45 degree angles for clean lines. Anchor tightly with nails or adhesive.
- Use nail holes and wood putty on natural trim for an invisible finish. Look for pre-finished options to avoid this step.
- Work from the floor up when installing door and window casings for proper fit.
- Apply caulk between trim and wall surfaces for a professional finish. Use paintable caulk that coordinates.
- Allow all trim adhesives to fully cure before sanding or painting to prevent lifting or damage.
Trim installation takes skill and precision. Take time to prepare surfaces properly. Measure twice and cut once for tightly joined corners. Follow manufacturer’s directions for adhesive application and drying times. The end result will integrate beautifully with your home’s style.
