Wood Moulding Types
If you’re planning to install laminate or engineered wood flooring, understanding the different wood moulding types is essential. Floor moldings and trims give your space a clean, professional finish by covering gaps, protecting edges, and creating smooth transitions between rooms and flooring surfaces.
What Is a Wood Moulding Profiles Chart?
A wood moulding profiles chart shows the different shapes and sizes of molding available from a manufacturer. Each profile is designed for a specific purpose, such as connecting two floors, covering expansion gaps, or finishing stair edges.
Using a profile chart helps you:
-
Choose the right molding for each area
-
Match your flooring color and style
-
Ensure a proper fit and professional finish
It’s a helpful reference when planning your flooring project.
Floor Wood Moulding Types
Below are the most common wood moulding profiles for flooring and how they are used.
Threshold Moulding (Baby Threshold)
Threshold molding is installed in doorways to finish the edge where the flooring ends. It is also used to connect two surfaces of different heights, creating a smooth and safe transition between rooms.

Flush Stair Nose Moulding
Flush stair nose molding is used on steps, landings, and elevated floors to protect edges from damage. The flush profile connects at the same level as the flooring, creating a seamless and modern look.

Quarter Round Moulding
Quarter-round molding is installed where laminate or engineered wood meets the baseboard. It covers expansion gaps and adds a finished appearance. It can also be used around cabinets and steps.

Reducer Moulding
Wood reducer molding slopes on one side to connect two floors of different heights, such as wood to tile, vinyl, or carpet. It reduces tripping hazards and creates a smooth transition.

T-Moulding
T-molding is used to join two floors of the same height. It is commonly installed in doorways without thresholds and in large rooms where expansion gaps are needed.
