This guide will provide homeowners with an overview of the different types of moulding and millwork, their uses, typical sizes, and how to choose the right materials for your rebuild, repair or remodel.

Types of Moulding and Their Uses

Moulding refers to the Trim or finishing elements used in home construction to provide a polished look where surfaces meet. Different types of moulding serve various purposes, and their selection can affect both the functionality and design of a space.

1. Baseboard Moulding

  • Use: Installed along the bottom of interior walls, baseboards cover the joint between the wall and floor, protecting the wall from damage and adding a decorative Finish.

  • Typical Sizes: Heights range from 3 to 8 inches, with common thicknesses between ½ inch to 1 inch.

  • Materials: Baseboards are available in wood, MDF, and PVC. Wood baseboards offer a traditional look, while MDF is more affordable and easy to paint.

2. Crown Molding

  • Use: Crown moulding is installed where walls meet the ceiling, adding a decorative transition and an upscale feel to rooms. It is often used in formal spaces like living rooms, dining rooms, or hallways.

  • Typical Sizes: Heights vary from 3 to 6 inches for standard rooms, but larger rooms or high ceilings may require 8-12 inch moulding. Thickness ranges from ½ inch to 1 inch.

  • Materials: Available in wood, plaster, MDF, and polystyrene. Wood and plaster offer a classic and detailed look, while MDF and polystyrene are more affordable and easier to install.

3. Chair Rail Moulding

  • Use: Installed horizontally across walls, typically at 32-36 inches above the floor, chair rails protect walls from furniture damage and serve as a visual divider between different wall treatments, such as paint and Wallpaper.

  • Typical Sizes: Widths range from 1 ½ to 3 inches, depending on the style and room scale.

  • Materials: Commonly available in wood and MDF, chair rails can be simple or highly decorative with patterns and grooves.

4. Casing

  • Use: Casing is used to frame doors and windows, covering the gap between the wall and the door or window frame. It provides a finished look while protecting the edges of Drywall or plaster.

  • Typical Sizes: Widths range from 2 to 4 inches, and thicknesses are typically ¾ inch.

  • Materials: Wood, MDF, and PVC are popular choices for casing. Wood is often chosen for its durability and finish options, while MDF and PVC are lower-cost alternatives.

5. Picture Rail Molding

  • Use: Installed high on the wall, near the ceiling, picture rails provide a way to hang artwork without damaging walls. This type of moulding is more common in older or traditional homes but can be used to add vintage charm to modern spaces.

  • Typical Sizes: Typically 1 ½ to 2 inches wide.

  • Materials: Available in wood and MDF.

6. Shoe Moulding and Quarter Round

  • Use: These are smaller mouldings installed at the joint between baseboards and flooring. Shoe moulding offers a more subtle finish than quarter round, but both are used to cover gaps between the baseboard and floor.

  • Typical Sizes: Shoe moulding is about ¾ inch wide, while quarter round has a ¾ inch radius.

  • Materials: Commonly made from wood, MDF, or PVC.

7. Panel Moulding

  • Use: Panel moulding is used to create decorative wall panels, often seen in Wainscoting or as frames on walls for a classic or upscale look.

  • Typical Sizes: 1 ½ to 3 inches wide.

  • Materials: Available in wood, MDF, and polyurethane, panel moulding can be painted or stained to match interior designs.

Types of Millwork and Their Uses

Millwork refers to any woodwork that is custom-made or pre-fabricated, including items such as doors, window frames, and stairway components. Millwork adds functional design elements that often define the architectural style of a home.

1. Doors

  • Use: Interior and exterior doors are customarily part of a home’s millwork. They come in a variety of styles, including paneled, flush, and French Doors.

  • Typical Sizes: Standard doors are 80 inches tall and 24-36 inches wide, though custom sizes are available.

  • Materials: Wood, Fiberglass, and MDF are commonly used. Solid wood doors offer durability and sound insulation, while MDF and fiberglass are budget-friendly alternatives.

2. Window Frames

  • Use: Window millwork includes sills, frames, and casing, which add structure and visual appeal to windows.

  • Typical Sizes: Custom sizes depend on window dimensions, but standard casing widths range from 2 ½ to 3 ½ inches.

  • Materials: Common materials include wood, PVC, and MDF. Wood provides a classic look, while PVC and MDF are often used in moisture-prone areas like bathroom.

3. Stair Components

  • Use: Stair millwork includes balusters, handrails, newel Posts, and treads. These elements are critical to both the structural integrity and aesthetic of a Staircase.

  • Typical Sizes:

    • Balusters: Heights range from 30 to 42 inches, depending on building codes and design.

    • Handrails: Typically 2-3 inches wide and must be positioned between 34-38 inches above the stair treads.

    • Treads: Common depths are 10 inches with a nosing that overhangs by about 1 inch.
