What Will You Need?
To create your wooden door trim, you will need the following materials:
- Wood boards (such as pine, oak, or maple)
- Measuring tape
- Saw (hand saw or power saw)
- Sandpaper
- Hammer and nails
- Wood glue
- Paint or stain (optional)
Once you have gathered all the necessary materials, you can create your custom wooden door trim. It is important to note that the specific measurements and tools may vary depending on the type of door and trim design you want to achieve.

8 Easy Steps on How to Make Wooden Door Trim
Step 1: Measure the Door Frame
Start by carefully measuring the dimensions of the door frame to ensure an accurate and snug fit for the trim. Use a measuring tape to measure the height and width of the door frame, recording the measurements on a notepad for reference. Be sure to measure from the inside edge of the frame, as this is where the trim will be installed.
Double-check your measurements to avoid errors, as even small discrepancies can lead to gaps or improper alignment. Additionally, if your door frame has any irregularities or uneven edges, make note of these so you can account for them during the cutting and installation process. Proper measurement is a critical first step for achieving a professional-looking finish.
Step 2: Cut the Trim to Size
Using the measurements you took earlier, carefully cut the trim pieces to the appropriate lengths. It’s essential to use a miter saw or a miter box to create clean, angled cuts for the corners, typically at a 45-degree angle, to ensure a snug fit.
Double-check each piece against the door frame before proceeding to confirm accuracy. If working with painted or stained trim, handle the pieces carefully to avoid scratches or chips during cutting. Take time with this step, as precise cuts are essential for a seamless and polished result.
Step 3: Attach the Trim to the Door Frame
Attach them to the door frame once all trim pieces are cut and double-checked for accuracy. Start with the top piece, positioning it carefully to align perfectly with the frame. Use finishing nails or a nail gun to secure the trim, ensuring the nails are evenly spaced for stability and a neat appearance.
Follow with the side pieces, making sure the mitered corners align snugly to form clean, continuous joints. Check the alignment frequently throughout the process, and use a level to ensure everything is straight. Don’t overdrive the nails, as that could damage the trim.

Step 4: Fill and Sand the Nail Holes
Once all the trim is securely in place, use wood filler to fill any visible nail holes or small gaps at the joints. Apply the filler with a putty knife, pressing it firmly into the holes to create a smooth, even surface. Allow the filler to dry according to the manufacturer’s instructions. After drying, use fine-grit sandpaper to gently sand the filled areas until flush with the trim surface. This step ensures a seamless finish and prepares the trim for painting or staining.
Step 5. Sanding the Trim
After filling and smoothing the nail holes, inspect the entire trim for rough patches, uneven edges, or imperfections. Use fine-grit sandpaper to sand the trim surfaces thoroughly, working along the wood grain to avoid scratches. This step ensures a smooth and professional finish while also helping the paint or stain adhere more effectively. Be sure to wipe down the trim with a damp cloth or tack cloth afterward to remove any dust generated during sanding.
Step 6. Priming the Trim
Once the trim has been sanded and cleaned, the next step is applying a primer coat. Primer helps seal the wood, covers any remaining imperfections, and provides an ideal surface for the paint to adhere to. Apply a high-quality primer evenly with a brush or roller, ensuring full coverage. Allow the primer to dry completely per the manufacturer’s instructions before moving on to the painting step.
Step 7. Painting the Trim
After the primer has dried, it’s time to paint the trim. Choose a high-quality paint suitable for trim, typically a semi-gloss or high-gloss finish, for durability and ease of cleaning. Use a brush or a small roller to apply the paint in thin, even coats, following the wood grain if applicable. Depending on your paint, you may need to use a second coat after the first one has dried completely. Be sure to check the manufacturer’s drying time for best results.

Step 8: Clean Up and Final Touches
Once the paint has dried thoroughly, carefully remove any painter’s tape to avoid peeling the fresh paint. Inspect the trim for imperfections or uneven areas, and touch up as needed with a small brush. Finally, clean your brushes and rollers promptly to maintain their quality for future use. Take a step back and admire your freshly painted trim, noting how it enhances the overall appearance of the space.
By following these steps and using high-quality materials, you can achieve a professional-looking paint job on your trim.
5 Things You Should Avoid
- Using Low-Quality Materials: Avoid purchasing cheap or low-quality wood and tools for your project. Inferior materials can lead to warping, splintering, and a lackluster finish, compromising the durability and appearance of your door trim.
- Neglecting Precise Measurements: Failing to measure accurately can result in ill-fitting pieces that create gaps or uneven edges. Always double-check your measurements before cutting to ensure every piece fits snugly.
- Skipping Sanding: Skipping the sanding process can leave the trim with a rough surface, making it difficult to achieve a smooth and polished final look. Proper sanding is essential to enhance the wood’s texture and ensure even paint or stain application.
- Applying Paint or Stain Too Soon: Rushing to paint or stain the trim without allowing proper preparation, such as drying after sanding or priming, can lead to poor adhesion and an uneven finish. Take the time to prepare the surface beforehand properly.
- Incorrect Installation Techniques: Using improper installation methods, such as incorrect nailing or gluing techniques, can cause loose or misaligned trim over time. Always follow best practices and use tools like a level to ensure accuracy during installation.
