10 DIY Small Space Decor Hacks That Make Your Home Look Bigger

A small room can become frustrating surprisingly fast. One extra chair blocks the walkway. A dark corner suddenly makes the entire room feel tighter. Then there’s the mirror you bought because every “make a room look bigger” article recommended one—only to discover it reflects a pile of laundry.

The trick isn't simply adding less furniture. It’s controlling what the eye notices.

Room Trends already covers the fundamentals of small-space planning, including circulation, furniture depth, vertical storage, and multifunctional pieces. This guide takes a narrower, more hands-on route: DIY decor changes that alter the visual proportions of a room without requiring a renovation.

Some cost almost nothing. Others need a Saturday afternoon, a drill, or a tin of paint.

The payoff can be surprisingly dramatic.

1. Hang Curtains Almost From the Ceiling

Most people install a curtain rod a few inches above the window. That works functionally, but visually it can emphasize the actual height of the window.

Try something different.

Move the rod considerably higher—ideally close to the ceiling—and use curtains that extend all the way to the floor. IKEA specifically recommends this approach for creating the impression of higher ceilings, and placing the curtains farther toward the room's edges can also make the space appear wider.

A simple DIY setup

1. Measure from the proposed rod position to the floor.

2. Buy or hem curtains so they reach the floor without a large puddle.

3. Position the rod several inches outside the window frame on both sides.

4. Keep the curtains pulled back when you want maximum daylight.

There's another useful trick: choose a curtain color close to the wall color. The window treatment then becomes part of the architecture rather than a dark visual stripe cutting across it.

Small room, taller illusion.

2. Build a Mirror That Reflects Something Useful

A mirror doesn't magically add square footage. Its value comes from what it reflects.

A large mirror facing a window can bounce daylight deeper into the room and create the impression of another visual opening. A mirror aimed at a blank wall, on the other hand, mostly gives you... another blank wall.

IKEA makes the same distinction in its small-space guidance, recommending mirrors for greater perceived depth and light.

For a DIY version, find a plain frameless or inexpensive framed mirror and upgrade the frame with thin wood trim.

A particularly practical example is IKEA's NISSEDAL mirror, available in a 15¾ × 59-inch size and designed to hang vertically or horizontally. Its manufacturer also specifies safety film on the glass.

Before drilling, stand where the mirror will go and look at its future reflection. If it captures a window, doorway, lamp, or open part of the room, you've found a good location.

If it captures clutter, move it.

3. Paint the Trim the Same Color as the Walls

This is one of those tiny changes that can be surprisingly effective.

Contrasting white trim creates a clear border around the room. That can look beautiful, but in a compact space it also creates more visual boundaries.

Instead, paint the baseboards, door trim, and walls in closely related shades—or use the same color with a different finish.

The result is quieter. The walls appear to continue rather than stopping at every piece of molding.

You don't necessarily need pure white, either. Paint manufacturers measure Light Reflectance Value (LRV) on a 0–100 scale, with higher numbers representing surfaces that reflect more light. Benjamin Moore, for example, lists Simply White OC-117 at an LRV of 89.52.

That doesn't mean “choose the highest LRV possible.” Test samples in the actual room. A color can behave very differently under morning sunlight, cloudy daylight, and artificial lighting.

4. Make a DIY Floating Shelf Instead of Adding Furniture

A small cabinet can consume 12–18 inches of floor depth. A wall-mounted shelf consumes almost none of it.

That makes floating shelves especially useful beside beds, above desks, or along narrow hallways.

The DIY version can be as simple as a wooden board, concealed brackets, sandpaper, and paint or stain.

But don't cover every inch of it with objects.

Use the shelf for two or three deliberate pieces: a small plant, framed photograph, candle, or a few books. Open shelving becomes counterproductive when it turns into a storage dump.

Room Trends' existing small-space guidance similarly warns that open shelving can create visual noise when every shelf becomes crowded.

The goal isn't maximum storage.

It's less furniture touching the floor.

5. Create a Faux Built-In With Paint

Built-ins look expensive because they visually merge storage with architecture.

You can fake part of that effect.

Take an inexpensive narrow bookcase or wall-mounted storage unit and paint the entire wall, trim, and shelving in one coordinated color. The individual furniture piece becomes less noticeable because its edges don't shout for attention.

For a brighter room, look at lighter neutral families rather than automatically reaching for stark white. Sherwin-Williams notes that LRV affects how a paint color responds to available light and recommends considering room orientation when selecting neutrals.

This hack works particularly well in small bedrooms and home offices.

One tall storage zone can look intentional.

Several unrelated cabinets usually look like several unrelated cabinets.

6. Swap a Heavy Lampshade for a Wall Light

Floor lamps are useful, but they occupy valuable floor area.

A wall-mounted sconce or compact plug-in wall light can move that function upward.

No rewiring is necessarily required if you choose a plug-in model.

Run the cable neatly down the wall using paintable cable clips or a slim cord cover. If you're renting, that can be a much easier solution than installing a permanent fixture.

For a bedroom, place the light beside the bed instead of using a nightstand lamp. For a desk, mount a directional light above or beside the work surface.

The room gains a little floor space—and the light itself becomes part of the wall rather than another object sitting on furniture.

7. Paint a Continuous “Window” of Light

Here's a slightly more creative DIY project.

Choose a pale, slightly warmer paint color and use it behind a window, mirror, or artwork area to create a visual focal zone. Keep the surrounding surfaces relatively quiet.

The trick is not to create a giant painted rectangle that looks like an accent wall from 2015. Instead, make the color transition subtle enough that the eye reads the whole area as one connected composition.

For very small rooms, soft whites, warm neutrals, and restrained natural tones are already a strong direction for 2026 interiors on Room Trends.

A painted focal area can therefore add personality without introducing another heavy visual object.

8. DIY a Slimline Picture Ledge

Gallery walls can become visually busy in compact rooms.

A picture ledge offers another option.

Install one narrow ledge and lean a few frames against the wall instead of hanging dozens of individual pieces. The artwork can be rearranged without drilling new holes every time you change your mind.

Keep the frame colors related. Mix sizes.

Then leave some wall visible.

That empty wall area matters. A small room doesn't benefit from having every surface decorated simply because there's available space. Visual breathing room helps the larger composition feel calmer.

If you want a more substantial effect, use two long ledges with generous vertical spacing rather than five tiny shelves scattered around the room.

9. Raise Visual Height With a DIY Vertical Stripe

Horizontal lines emphasize width.

Vertical lines pull the eye upward.

You don't need to wallpaper an entire room to use that principle. Create a subtle vertical pattern on one wall with painter's tape and two closely related paint colors.

For example, use a warm off-white base and a slightly deeper beige for narrow vertical stripes. Keep the contrast modest.

The result should be discovered rather than announced.

Another option is vertical wood battens, but measure carefully before cutting. Uneven spacing becomes painfully obvious once the pieces are on the wall.

And don't overdo it. One feature wall is usually enough.

10. Give Furniture an “Air Gap”

This final hack costs almost nothing.

Look underneath your furniture.

If every cabinet, sofa, bench, and table sits directly on the floor with a heavy solid base, the room can feel visually dense. Furniture with visible legs allows more floor to remain visible, which can make the room feel lighter.

IKEA specifically recommends furniture with lighter frames and bases, along with glass tops and doors, as ways to create a roomier visual effect.

You can sometimes create the same effect yourself.

Add tapered legs to a basic cabinet. Replace chunky feet with slimmer furniture legs. Raise a low bench slightly if its construction allows it.

Just don't compromise stability. A cabinet that wobbles because you wanted a two-inch visual gap isn't a successful decor hack.

A Few Mistakes That Can Undo the Effect

A mirror facing a messy desk isn't helpful.

Neither is a beautiful floating shelf covered with 17 objects.

The same goes for pale paint paired with heavy black curtains, oversized furniture, and a crowded floor. One clever trick can't compensate for five competing visual problems.

Start with the largest obstruction.

If the curtains are too short, fix them. If the room is dark, work on reflection and lighting. If the walls are fragmented by too many colors, simplify the palette.

And measure before cutting anything. Room Trends' broader small-space guidance makes the same practical point: furniture and layout decisions should be tested against real circulation rather than judged only from a floor plan or photograph.

Small-Space Decor FAQs

What is the easiest DIY way to make a small room look bigger?

Start with curtains and a strategically positioned mirror. Raising curtains toward the ceiling can exaggerate wall height, while a mirror reflecting daylight or an open area can add perceived depth.

Does painting a small room white really make it look bigger?

It can help, but white isn't the only option. Soft warm neutrals and pale colors can create a continuous, reflective background. Pay attention to LRV and the room's natural lighting rather than choosing paint based solely on a color card.

Should a small room have a large mirror?

Often, yes—but placement matters more than simply choosing the largest possible mirror. Aim it toward a window, doorway, light source, or open section of the room instead of a cluttered corner.

Are floating shelves better than cabinets in a small room?

Not automatically. Floating shelves preserve visible floor area, but closed cabinets are often better for hiding clutter. The right choice depends on what you're storing and how visually busy the room already is.

Can dark colors work in a small room?

Absolutely. Dark colors can create a dramatic, intimate effect, especially when used selectively. If the goal is specifically to make the room feel larger and brighter, though, lighter reflective surfaces are generally the safer starting point.

Make One Change Before Buying Anything

The best part of these hacks is that you don't need to redo the whole room.

Start with one wall.

Move the mirror. Raise the curtain rod. Remove the bulky lamp. Paint the trim. Build one floating shelf.

Then live with the change for a few days.

Small rooms are excellent teachers. You'll notice what blocks the light, what catches your eye first, and which piece of furniture feels unnecessarily heavy. That observation is often more valuable than another shopping trip.

Make the room visually lighter first. Then decorate the space you've created.
