Space-Themed Nursery: 12 Design Ideas With Wall Decals

Space nurseries have gone from niche to mainstream — and in 2026, they’re one of the most searched nursery themes online. The appeal is obvious: space is wonder, exploration, and endless possibility. Perfect themes for a child just beginning their story.

The challenge is execution. Done well, a space nursery feels awe-inspiring and timeless. Done poorly, it looks like a knockoff NASA cafeteria. The key is in the details — especially what you put on the walls.

Here are 12 design ideas that actually work, built around removable wall decals so you can change the room as your child grows.

Why Wall Decals Are Perfect for Space Nurseries

Space-themed wall murals and wallpapers are beautiful but expensive and permanent. Space nurseries have a natural shelf life — around age 4–6, most children develop their own preferences and want to redecorate.

Removable fabric wall decals give you:
– The visual drama of a space mural without the permanent commitment
– The flexibility to remove or swap pieces as the child grows
– A nursery that photographs beautifully for the memories
– Genuine cost savings (a decal set at $50–$80 vs. a painted mural at $600–$2,000)

All DecalHouse space wall decals are available in repositionable fabric — ideal for nurseries where walls will eventually change.

The 12 Ideas

Idea 1: Watercolor Galaxy Accent Wall

A large watercolor-style galaxy — soft washes of deep blue, purple, and teal with scattered stars — covers the wall behind the crib. Unlike hard-edged vector art, watercolor galaxy decals have soft, blended edges that feel dreamlike and painterly.

Best for: Modern, artistic nurseries. Gender-neutral.

Color palette to build around: Navy, dusty teal, soft gold, warm white.

Room note: Keep other walls neutral (white, very light grey, or warm ivory) so the galaxy wall remains the focal point.

Idea 2: Solar System Planet Collection

Individual planet decals arranged in a loose solar system arc across one wall — not to scale, but in the right order and with the right character. Saturn with its rings. Jupiter’s bands. Earth’s blue.

Best for: Educational angle; grows well with the child (planets are still interesting at age 8).

Sizing tip: Make the sun large (12–18 inches) and scale down from there. Place the sun at one end of the wall and trail the planets across the surface.

Idea 3: Astronaut Floating in Space

A single large astronaut figure — helmet, suit, tether trailing behind — positioned as if floating on the ceiling or high on the wall. The isolation of the figure against a white or dark wall creates a sense of wonder and scale.

Best for: Minimalist nurseries that want one strong statement piece.

Pairing: Add a handful of small star scatter decals around the astronaut for context without clutter.

Idea 4: Constellation Map Ceiling

Take the space theme vertical: constellation lines and star dots applied to the ceiling above the crib or reading chair. Looking up becomes an experience — like sleeping under the real sky.

Installation note: Use the same application technique as walls — prep the surface with an alcohol wipe, apply slowly. Ceiling work is easier with two people.

Bonus: Glow-in-the-dark versions of this concept (decals printed with phosphorescent ink) are increasingly available and genuinely magical in a nursery.

Idea 5: Rocket Ship Launch Scene

A classic retro rocket ship — fins, porthole, rising flame trail — positioned at the bottom corner of the wall with stars scattered above it. The rocket becomes a visual anchor that grounds the rest of the space-themed room.

Style direction: Vintage NASA aesthetic (cream, red, grey) for a retro room vs. bright modern cartoon style for a more playful nursery.

Idea 6: Moon Phases Strip

A horizontal strip of moon phases — new moon through full moon and back — running along the wall at adult eye level or along the top of the wall near the ceiling. Simple, elegant, and scientifically accurate.

Best for: Modern, minimal nurseries where complexity would feel busy.

Color tip: White or cream phases on dark navy or charcoal are the most striking. Gold moons on dark walls are also stunning.

Idea 7: “Reach for the Stars” Quote With Star Cluster

A two-element composition: a meaningful quote in a clean, modern typeface accompanied by a cluster of stars radiating outward from the text. This is both a visual element and a piece of meaning-making for the child’s room.

Popular quotes for space nurseries:
– “Reach for the Stars”
– “Born to Explore”
– “The Sky Is Not the Limit”
– “Adventure Awaits”

Idea 8: Pastel Planet Set (Gender-Soft Version)

Traditional space themes can skew masculine. A pastel planet set — planets in dusty rose, mauve, soft sage, and warm lavender — gives a space theme a softer, more traditionally “nursery” feel while keeping the astronomical subject matter.

Best for: Nurseries where the family wants a space theme but also appreciates a softer, more romantic palette.

Idea 9: Galaxy + Botanical Hybrid

An unusual but increasingly popular pairing: space elements (stars, moon phases, a single planet) combined with botanical elements (trailing vines, small leaves, tiny flowers) creates a “cosmic garden” aesthetic.

The contrast between the infinite and the organic feels both surreal and comforting — appropriate for a nursery in a way that pure cold sci-fi isn’t.

Idea 10: Full Crib Wall Mural (Peel-and-Stick)

For those who want maximum impact: a full-wall space mural — a detailed scene of a galaxy, nebula, or starfield — applied as a large-scale peel-and-stick panel to the wall directly behind the crib.

This gives wallpaper-level coverage with decal-level removability. Pair with simple furniture and minimal other decals to let the mural do all the work.

Idea 11: UFO and Alien Friends (Playful Version)

For a lighter, more whimsical take: cartoon UFOs, friendly green aliens, flying saucers, and retro space cars in bright, cheerful colors. This reads as “fun space” rather than “serious space” — better for families who want humor and play in the nursery atmosphere.

Color palette: Lime green, bright teal, electric blue, and white on a white wall for maximum cartoon energy.

Idea 12: Dark Accent Wall + White Constellation Overlay

Paint or use peel-and-stick wallpaper to create a single deep navy or charcoal accent wall. Then overlay it with white constellation line decals and small star dots.

The layered effect — dark background + white lines + tiny stars — is more sophisticated than any single decal can achieve alone and genuinely looks like a piece of intentional interior design.

This is the highest-effort but highest-impact option on this list. The result photographs beautifully and creates a room that feels special for years.

Putting a Space Nursery Together: Room Checklist

The wall:
Choose your anchor decal (galaxy scene, constellation ceiling, or planet arc) and build from there.

Furniture:
– White or natural wood crib (dark crib competes with the wall)
– Mid-century or Scandinavian style dresser/changing table
– Rattan or woven textures soften the “tech” feel of space themes

Textiles:
– Deep navy, dusty teal, or warm white crib sheets
– A star or constellation-print rug
– Blackout curtains in navy or soft grey (doubles as darkness for sleep)

Lighting:
– A warm-toned nightlight rather than cool white (cool lighting makes space themes feel clinical)
– A star projector for bedtime — the decals are static, but a projector adds magic

Accessories:
– Globe or lunar phases artwork on a shelf
– Natural wood toy rocket or astronaut figure
– Small NASA prints in thin frames
