Painted Trim Ideas: 15 Bold Outline Tricks That Make a Plain Room Look Custom

Painted trim ideas are taking over home feeds this month, and one question started it: outlining a room in black? A bedroom makeover reel that traced the ceiling line, closet doors and window in dark paint pulled about 931,000 views and 29,000 likes in less than a week, and part two added another 480,000 views. It looks like expensive millwork, but it is just paint, tape and patience. Renters are copying the look with peel and stick trim and fabric walls too. Here are 15 bold outline tricks, from a single black line at the ceiling to a sweet scalloped edge, that make a plain room look custom..

Painted Trim Ideas That Fake Expensive Millwork

Have you ever walked into a room and thought it looked custom, even though nothing fancy was added? Often the secret is just a few lines of paint. A thin dark outline at the ceiling, a painted frame around a window or a faux panel on a flat door can make a plain room look like it has expensive millwork. The best part is that paint is cheap, forgiving and easy to change. With painter’s tape, a steady hand and an afternoon, you can try one of these looks this weekend. Which room in your home feels a little too plain..

You will need: Painter’s tape, a small angled brush, a mini foam roller, a level, a pencil and sample pots of paint.

How to make it: 1. Pick one wall or one door to start. 2. Choose a color darker than your wall. 3. Tape and level every line. 4. Paint two thin coats and pull the tape while the paint is still a little wet.

A Black Line Where the Wall Meets the Ceiling

This is the look behind the bedroom makeover reel that asked, outlining a room in black? It reached about 931,000 views and 29,000 likes in less than a week. A thin black line traced where the walls meet the ceiling makes the room look sharp and finished, almost like a drawing. It hides wobbly ceiling edges too. Use a ladder safely and have someone hold it. Start with one room before you commit to the whole house. Would you be brave enough to try black?

You will need: Painter’s tape, a small angled brush, black paint in an eggshell or satin finish, a level and a sturdy ladder.

How to make it: 1. Run tape along the ceiling edge. 2. Run a second line of tape about one inch below it on the wall. 3. Paint between the tapes in two thin coats. 4. Peel the tape slowly at an angle.

Faux Panels on Flat Closet Doors

Flat closet doors are one of the most boring things in a home. In part two of the same makeover, which passed about 480,000 views, plain doors got painted outline panels with softly rounded corners. From across the room, they look like real molding. Use a jar lid or a small plate to trace the curves. Black looks bold and modern, while a soft taupe looks classic. This is one of the easiest painted trim ideas to undo if you change your mind. Which doors in your house would you try first?

You will need: Painter’s tape, a jar lid for corners, a pencil, a ruler, a fine angled brush and paint.

How to make it: 1. Measure and mark one or two rectangles on each door. 2. Trace curved corners with a jar lid. 3. Tape the straight sides. 4. Paint the outline with a fine brush and touch up the curves.

Frame a Window Like a Piece of Art

A painted frame a few inches outside the window trim makes the window look bigger and turns the view into a picture. It works best on a window you already love looking out of, and it is one of the quickest painted trim ideas to finish. Keep the outline straight with a level, and choose a width that matches the room: thin for small rooms, wider for big ones. Add linen curtains and a few plants and it feels like a cozy cottage. Have you ever thought of your window as wall art?

You will need: Painter’s tape, a level, an angled brush and paint in a darker shade.

How to make it: 1. Mark a line about two to three inches outside the window trim. 2. Tape both edges of the stripe. 3. Paint two thin coats. 4. Remove the tape and touch up corners.

Contrast Door Frames and Baseboards

Painting your trim a deep color instead of white is one of the biggest decor shifts of the year. Chocolate brown, deep green or charcoal on door frames and baseboards makes the walls look softer and the room feel cozy. It also hides scuffs from shoes and vacuums. Use a semi gloss finish so it wipes clean. Clean and lightly sand the trim first so the paint sticks. Would you go brown, green or charcoal?

You will need: Sandpaper, a damp cloth, painter’s tape, a 2 inch angled brush and semi gloss trim paint.

How to make it: 1. Clean the trim and sand it lightly. 2. Tape the wall edge and the floor. 3. Paint two thin coats with an angled brush. 4. Let it cure for a few days before scrubbing.

Painted Trim Ideas for the Ceiling: A Faux Coffered Border

Coffered ceilings cost a fortune, but a painted border gives a similar framed look for the price of a quart of paint. Tape a stripe a short distance in from the ceiling edges and paint it in a deep color. It draws the eye up, makes a light fixture look grand and feels very custom. Working overhead is tiring, so take breaks and keep the ladder steady. This is one of the boldest painted trim ideas, and guests always notice it. Which room has a ceiling worth framing?

You will need: A tape measure, painter’s tape, a mini roller with an extension pole, an angled brush, paint and a sturdy ladder.

How to make it: 1. Measure the same distance in from each wall. 2. Tape both edges of a 3 to 4 inch stripe. 3. Roll and brush two thin coats. 4. Pull the tape and touch up.

A Painted Arch Instead of a Headboard

No headboard? Paint one. A big arch behind the bed in terracotta, sage or dusty pink gives the room a calm focal point. Tie a string to a pencil and a nail to draw a perfect curve. It is a renter friendly idea too, since it is just paint you can cover later. The arch should be a little wider than the bed and reach about two thirds up the wall. What color would make your bedroom feel calm?

You will need: A pencil, string, a small nail, painter’s tape, a small roller, an angled brush and paint.

How to make it: 1. Mark the center above the bed. 2. Use the string and pencil to draw the curve. 3. Tape the straight sides. 4. Paint inside the lines and do the curve by hand.

A Thin Line at Chair Rail Height

Want the look of a chair rail without cutting wood? Paint a thin line around the room at about one third of the wall height. Paint the wall below a slightly different shade and the line looks like real trim. It is perfect for dining rooms and hallways. Use a laser level or a long level to keep it straight, since this line runs a long way. Many painted trim ideas start here because it is simple and fast. Would you pick a soft or bold pair of colors?

You will need: A level, painter’s tape, two wall colors, a dark accent color and a small brush.

How to make it: 1. Mark a line about 32 to 36 inches from the floor. 2. Paint the lower wall first. 3. Tape a thin stripe over the color change. 4. Paint the stripe in a dark accent color.

Painted Trim Ideas for Stairs: Outlined Risers

Stairs are a great place to play with outlines. A thin dark border around each riser makes a plain staircase look crisp and designed. Keep the treads plain and non slip for safety, and only paint the risers. Work from the top down so you never have to step on wet paint, or paint every other step one day and the rest the next. Would you outline your stairs in black or a color?

You will need: Painter’s tape, a small angled brush, a sanding sponge and floor or trim paint.

How to make it: 1. Clean and lightly sand each riser. 2. Tape a border about one inch in from the edges. 3. Paint the border carefully. 4. Paint every other step first so the stairs stay usable.

Painted Trim Ideas for Living Rooms: Picture Frame Boxes

Picture frame molding is a classic look in old homes. You can fake it with painted rectangles in a shade slightly darker than the wall.

Peel and Stick Trim for Renters

Renting does not mean living with plain walls. Thin self adhesive trim strips can be stuck on in rectangles and painted the same color as the wall for a real molded look. When you move out, they peel off. The same creator even draped a canvas drop cloth from a ceiling rod for a soft fabric wall, and that video passed about 312,000 views.

A Checkerboard Doorway Outline

For a playful twist, paint a checkerboard border around a doorway. It looks fun in kids rooms, playrooms and laundry rooms.
