We love adding picture frame moulding to rooms that lack character and personality. From the architectural detail it adds to the way it instantly evokes a sense of old-home charm, it’s subtle but dramatic, traditional yet modern, and (best of all) a totally approachable DIY project.
We’ve added this kind of moulding to our projects such as Greene Avenue Glow Up and New Heights Reno, and every time it transforms the room. Whether you want to elevate a dining room, create a focal wall in a hallway, or add polish to a bedroom, this guide will walk you through everything you need to do it right.
What You’ll Need
Pre-primed moulding or trim pieces (choose your favorite profile)
Level or laser level for precision
Nail gun + finish nails
Caulk (paintable)
Paint (our favorite paint for moulding)
Step 1: Plan Your Layout
Start by deciding how many “frames” you want on the wall and how large each should be. A typical layout includes symmetrical rectangles that are vertically aligned with even spacing between them.
We suggest:
- 4–6″ between moulding and ceiling/baseboards
- 2–4″ between each frame
- Even spacing left-to-right
Step 2: Cut Your Moulding
Once you’ve finalized your layout, measure each frame side and cut your moulding at a 45° angle using a miter saw. The cuts should meet cleanly in the corners to create the picture frame shape.
Pro tip: Label the back of each piece as you go to avoid mix-ups during installation.
Step 3: Install the Frames
Using a nail gun or finishing nails, install each piece directly onto the wall. Start with the bottom piece of each frame and build your way up, using a level to ensure straight lines.Apply a little wood glue at the joints if you want an extra-strong hold. Once each frame is up, step back and admire your handiwork!
Step 4: Fill, Caulk, and Sand
Now the polish. Use wood filler to patch nail holes and seams. Caulk along the edges where moulding meets the wall for a seamless look. Once everything’s dry, lightly sand until smooth.
Step 5: Paint
This is where it all comes together. You can match your wall color for a subtle, architectural look—or choose a contrasting shade to make the moulding pop. Want to go full drama? Paint everything the same deep hue for a tone-on-tone moment that feels rich and enveloping.

Picture frame moulding is a designer trick we’ll never stop loving. It’s elegant, timeless, and completely customizable. It gives flat walls texture, adds value, and—most importantly—makes your space feel finished.
Whether you’re restoring a brownstone to its former glory or simply want to upgrade a blank builder-grade wall, this is a project that delivers a major impact with minimal materials.
