Space-Themed Kids’ Room Ideas for Your Little Astronaut

If your child is fascinated by rockets, planets and everything beyond our atmosphere, a space-themed room gives their imagination plenty of room to explore. The best part is that you don’t need to transform every inch of the bedroom into a spaceship to make the theme come to life.

A few well-placed planets, a moon above the bed or rockets travelling across the wall can completely change how the room feels. Keep the furniture and larger pieces simple, then use the walls to tell the story.

The key to creating a space-themed kids’ room is choosing one main celestial feature, then building around it with smaller planets, stars, moons or rockets. Leaving some open wall space between the designs keeps the room feeling balanced rather than busy.

If you’re looking for a place to start, browse our Kids’ Space Wall Decals Collection for planets, spaceships, moons, stars and other celestial designs.

1. Build the Room Around the Planets

Planets make a great starting point because they instantly create a space theme without making the whole room feel overly decorated. They also work for a wide range of ages, from a baby’s nursery to an older child’s bedroom.

Our Blue Planets Wall Decals bring different planetary shapes and details to the wall with a watercolour-inspired look. Instead of arranging the planets in a straight line, place them at different heights and vary the distance between them. The irregular layout helps create the illusion that the planets are actually floating through space.

You can also take a softer approach with more neutral celestial colours. Warm whites, beige, cream, natural wood and muted planetary tones can create a space-themed room that feels calm rather than bright or heavily themed.

Whichever direction you choose, resist the urge to fill every empty spot. A few larger planets surrounded by open wall space can make just as much impact as an entire galaxy.

2. Let the Rockets Tell a Story

Planets create the setting, but rockets are where the adventure begins.

Our Spaceship Wall Decals can be arranged individually, which means you can create movement rather than placing everything in a predictable row. Position a rocket as though it’s blasting off beside the bed, send another toward a planet, then scatter smaller stars and celestial details along its path.

This works especially well around a bed, play area or reading nook because the wall becomes part of the child’s imagination. Suddenly, the bed isn’t just a bed. It’s mission control.

You also don’t need to use every piece in the same area. Let a few rockets or stars travel onto an adjoining wall to make the room feel more connected.

3. Make the Moon the Main Attraction

If you prefer a simpler space-themed room, start with one oversized element rather than lots of smaller pieces.

A large Blue Moon Wall Decal can become the focal point behind a bed, crib, dresser or reading chair. Add a few stars or planets around it if you want more detail, or leave plenty of the original wall showing and let the moon stand on its own.

This is a great option if you want the room to feel celestial without making everything space themed. Keep the bedding and furniture simple, bring in a few colours from the wall decor, and let the moon be the piece that gives the room its personality.

Sometimes one giant moon is all it takes to send a room into orbit.

4. Scatter Stars Across the Room

Stars are one of the easiest ways to connect all the larger elements in a space-themed bedroom. They can fill the gaps between planets and rockets, lead the eye from one side of the room to the other or extend the design beyond a single feature wall.

Rather than spacing every star evenly, vary the distance between them. Cluster a few together, leave larger gaps in other areas and use them to create movement around the room. The finished wall will feel more like a night sky and less like a repeating pattern.

You can also let a few stars travel upward toward the ceiling. This can make the space theme feel more immersive without covering every wall in the room.

If you’re combining several types of decals, place your largest planets, moons or rockets first. Once those anchor pieces are in position, use the stars to fill in the spaces that need a little something extra.

5. Create a Space Nursery That Can Grow With Them

A space nursery can be sweet and playful without feeling overly babyish. That makes celestial decor especially useful if you’d like the room to last beyond the crib stage.

For a softer look, pair moons, stars and planets with warm white, cream, pale blue, beige or natural wood. Smaller celestial designs can create enough interest around the crib or changing area without making the room feel too busy.

As your child gets older, the crib can become a bed and the baby accessories can disappear, while the overall space theme still works. You can add more adventurous elements, like rockets and constellations, or simply keep the planets and stars as the room evolves.

A theme that can survive the jump from baby to big kid is always a win.

How to Arrange Space Wall Decals

Before installing your decals, decide which part of the wall should attract attention first. This could be a large moon, a cluster of planets or a rocket near the bed. Place those larger elements first, then work outward with your medium and smaller designs.

Avoid creating perfectly straight rows unless that’s the look you specifically want. Varying the height, direction and distance between pieces creates more movement and makes the arrangement feel natural.

For a softer, simpler space room, spread the decals farther apart and leave plenty of the original wall visible. If your child wants to feel surrounded by their own galaxy, bring the elements closer together and use stars or smaller designs to connect them.

Before sticking everything down, take a moment to step back and look at the wall from across the room. Sometimes what looks perfectly spaced when you’re standing two feet away feels completely different from the doorway.

What Colours Work in a Space-Themed Kids’ Room?

Blue and navy might be the first colours that come to mind when you picture outer space, but they’re far from your only options.

For a classic space room, blue can be paired with white, grey and natural wood. For something warmer, try adding tan, rust, camel or walnut. A softer nursery can use cream, pale blue and light wood, while neutral planets can look beautiful against warm white or beige walls.

You can also let the wall decor determine the rest of the palette. Pick two or three colours from your planets, rockets or stars and repeat those shades in the bedding, rug, storage or smaller accessories.

The room will feel coordinated without requiring every single thing in it to have a planet printed on it.

How Do You Create a Space Room Without Overdoing the Theme?

Choose where you want the theme to make the biggest statement.

If you’ve created an entire galaxy on the wall, you probably don’t also need rocket bedding, star curtains, planet lamps and an astronaut rug. Let the walls do the fun part and give the rest of the room some breathing room.

Simple bedding, natural wood furniture, solid-colour textiles and everyday storage can balance a more playful feature wall. The room will still clearly belong to a space-loving kid, but it won’t feel like everything came from one matching collection.

This approach also makes the bedroom easier to update as your child grows. Furniture and larger pieces can stay while the smaller details evolve with their interests.

Space-Themed Room Ideas for Different Ages

For a nursery, keep the layout a little simpler. A large moon, a small group of planets or stars scattered above the crib can create plenty of interest while maintaining a calmer feeling.

Toddlers and younger children may love a room with more of a story. Rockets can blast off toward planets, stars can travel around a reading nook, and different celestial elements can turn a play area into their own little universe.

For older children, try leaning more heavily into planets, moons, stars and constellations. A celestial room can grow surprisingly sophisticated as the furniture, bedding and colour palette mature.

That’s one of the reasons space works so well as a kids’ room theme. Their favourite part of the universe may change, but the theme itself has plenty of room to grow.

Frequently Asked Questions About Space-Themed Kids’ Rooms

How do you decorate a space-themed bedroom?

Start with one main wall and choose a focal point such as a moon, planets or rockets. Add smaller stars and celestial elements around the larger pieces, then repeat a few of the colours from the wall decor in the bedding, rug or accessories. Leaving some parts of the room simple will keep the space theme from becoming overwhelming.

What colours are best for a space-themed bedroom?

Navy, blue, white and grey are classic space-room colours, but you can also use cream, beige, natural wood, tan and other warm neutrals. For a nursery, softer colours can make the celestial theme feel calmer, while deeper colours can create a more dramatic room for an older child.

Where should I put planet wall decals?

Planet decals work well behind a bed or crib, above a dresser, around a reading nook or across a larger feature wall. Placing the planets at different heights and varying the distance between them creates the feeling that they’re floating through space.

Can I use star decals on the ceiling?

You can extend a few stars from the wall toward the ceiling to create a more immersive celestial effect, provided the surface is suitable for the decal material. Always follow the installation recommendations for the specific product.

Is a space theme good for a nursery?

Yes. Moons, planets and stars can create a playful nursery without feeling overly babyish. Choosing a softer colour palette and a simpler decal arrangement can help create a calm space that can transition into a toddler or big-kid room later.

How can I make a space-themed bedroom grow with my child?

Keep larger furniture relatively neutral and use the walls and smaller accessories to establish the theme. Celestial designs such as moons, planets, stars and constellations can work across several ages, making it easier to update the room without completely redecorating.

Are Urbanwalls space wall decals removable?

Urbanwalls wall decals are designed to be removable from properly prepared walls, but they’re intended for one-time application rather than being moved and reused. For best results, make sure your wall is clean and properly prepared before installation, and allow freshly painted walls to fully cure before applying decals.

Create a Universe of Their Own

You don’t need to recreate the entire solar system to give your little astronaut a room they’ll love. Start with the part of space that captures their imagination and build from there.

Maybe that’s a giant moon above the bed, planets floating across the nursery or rockets blasting toward the ceiling. Add stars and smaller celestial details where the room needs them, then keep enough simplicity elsewhere to let the walls shine.

The best part is that there’s no single correct way to build a galaxy. You get to arrange the planets, decide where the rockets are headed and create a room that feels completely their own.
