Picture rail molding helped make a compact 140-square-foot bedroom feel noticeably taller, in a moody green makeover by photographer Meghan Beierle-O'Brien. The project is a clear case study in how a single horizontal trim detail can change the perceived scale of a small room, proving you do not need structural changes to make a cramped space feel more generous.
The inspiration behind the makeover
Beierle-O'Brien was inspired by a client's project and by her own dark green IKEA curtains, which finally pushed her to transform the primary bedroom she shares with her husband into a space she actually wanted to spend time in. Rather than fight the room's small footprint, she leaned into it, building a rich, enveloping scheme anchored by those existing curtains.
Starting from something she already owned kept the project grounded. Instead of choosing a palette in the abstract, she let the green of the curtains dictate the direction, which is a reliable way to keep a small-room scheme cohesive and personal rather than generic.
Why picture rail molding works in small rooms
Picture rail molding runs horizontally around the upper portion of a wall, originally designed so artwork could be hung from it without nailing into plaster. In a tight 140-square-foot footprint, it does something more useful: it draws the eye upward, which is a classic decorating trick for adding a sense of height and architectural character to a low or boxed-in room.
- Room size: 140 square feet, a genuinely small bedroom.
- Key detail: Picture rail molding to add perceived height.
- Palette: Moody dark green, tied to existing IKEA curtains.
- Goal: A primary bedroom the owners genuinely enjoy spending time in.
Pairing trim with a moody palette
The combination at work here is deliberate and worth copying. A darker, enveloping color can make a small room feel cozier and more intentional rather than simply smaller, dissolving the corners so the walls feel less confining. A horizontal trim line near the top of the wall then guides the eye upward, counteracting the low, boxed-in feeling that plagues many small bedrooms.
Tying the whole scheme to an existing element, in this case the dark green curtains, keeps the look unified and gives the palette a clear anchor. The trim and the color are not competing; they are working toward the same goal of making 140 square feet feel taller and more considered.
The takeaway for your own space
The makeover is a reminder that small bedrooms do not have to feel cramped or like an afterthought. A considered color scheme paired with a height-enhancing trim such as picture rail molding can transform how a modest room feels, without the cost or disruption of knocking down walls or raising ceilings. For anyone weighing whether a compact or rented bedroom is worth the effort, this project makes the case that thoughtful detailing pays off even in just 140 square feet.
It also shows the value of drawing inspiration from work you already admire, then adapting it to your own constraints, exactly as Beierle-O'Brien did with a client's project and her own curtains.

Frequently asked questions
What is picture rail molding?
It is a horizontal trim that runs around the upper portion of a wall, traditionally used to hang artwork. In small rooms it doubles as a design device, drawing the eye upward to make the space feel taller.
How big was the bedroom in this makeover?
Just 140 square feet, a genuinely compact primary bedroom, which is what makes the perceived height gain from the trim so notable.
Does a dark color make a small room feel smaller?
Not necessarily. As this project shows, a moody, enveloping color can make a small room feel cozier and more intentional, especially when paired with a height-enhancing detail like picture rail molding.
