For the kid who can name the planets before they can tie their shoes, a space-themed room is pretty hard to beat. Planets, rockets, moons and stars can turn an ordinary bedroom into somewhere that feels ready for an adventure, without requiring you to redesign the entire room.
The best space-themed kids’ rooms also leave a little room for imagination. Instead of trying to recreate the solar system perfectly, think about the walls as your child’s own little universe. Planets can orbit the bed, a rocket can blast off beside a bookshelf, or stars can travel all the way up the wall and onto the ceiling.
A great space-themed bedroom combines one or two larger celestial elements with smaller stars, moons or rockets, then leaves enough open wall space for the design to breathe. You can go bold and dramatic or keep the palette soft enough for a nursery.
If you’re ready to start exploring, browse our Kids’ Space Wall Decals Collection for planets, spaceships, moons, stars and other celestial wall designs.
1. Start With the Planets
Planets are one of the easiest starting points for a space-themed bedroom because they immediately establish the theme without requiring every other item in the room to match.
Our Blue Planets Wall Decals have a watercolor-inspired look with different planetary shapes and details. Rather than arranging them in a perfectly straight line, spread them across the wall at different heights to create the feeling that they’re floating through the room.
For a more neutral take on outer space, the newer Planet Wall Decals use a neutral palette with watercolor-inspired planets, moons and celestial textures. The full set contains 15 unique planetary designs, ranging from smaller 5-inch pieces to larger designs over 20 inches.
You don’t need to fill every inch of the wall. A few larger planets with plenty of space around them can make the room feel more expansive, while a denser arrangement creates more of an immersive galaxy effect.
2. Add Rockets for a Room That Feels Like an Adventure
If planets set the scene, rockets bring in the story.
Spaceship Wall Decals are especially fun in a bedroom or playroom because you can arrange the individual pieces to create movement across the wall. Instead of placing everything at the same height, imagine where the rockets are headed. Angle one upward beside the bed, scatter stars around it and place a moon or planet farther along its path. The Spaceship design remains part of Urbanwalls' current Kids' Space collection.
This is where wall decals have a big advantage over a fixed repeating pattern. Your child’s room doesn’t have to look exactly like anyone else’s. You decide where the adventure begins and where the rockets are going.
And yes, a rocket blasting toward the ceiling is considerably more exciting than a blank wall.
3. Use One Oversized Moon as the Focal Point
Not every space room needs dozens of elements. Sometimes one oversized celestial design can do most of the work.
A large moon creates a natural focal point behind a bed, crib, reading chair or dresser. From there, you can add smaller stars or planets around it, or leave plenty of open wall space and let the moon stand on its own.
Our Blue Moon Wall Decal is still part of the current Kids’ Space collection, so the beautiful oversized moon from the original version of this post can stay.
This approach is particularly useful if you want a space theme that doesn’t feel overly busy. Keep the furniture and bedding relatively simple, make the moon the star of the wall, and bring in smaller celestial details elsewhere in the room.
4. Fill the Sky With Stars
Stars are the supporting cast of a space-themed room, but they’re also what can pull the whole design together.
Use larger planets or a moon as your anchors, then scatter smaller stars into the empty spaces around them. Urbanwalls' current space collection includes several star options, including Twinkle Stars, Seeing Stars and Five Point Stars, as well as Constellation Wall Decals.
You can keep the stars concentrated around your larger space decals, scatter them across the entire wall, or let a few travel upward toward the ceiling. For an even more immersive look, continue some of the stars onto the ceiling so the room feels like it extends beyond the four walls.
The trick is not making the spacing too perfect. A little variation in the distance between stars usually creates a more natural, scattered-sky effect.
5. Create a Space Nursery That Can Grow With Them
A space-themed nursery doesn’t need to be dark navy with rockets covering every surface. If you want something softer, start with a lighter wall color and use celestial details as accents.
The Little Space Explorer Decal Pack is one option for creating a smaller-scale celestial scene. The current set includes a full moon, crescent moon, astronaut, spaceship, four planets and stars, with pieces ranging from about one inch to 6.5 inches.
Pairing a smaller decal set with warm white, natural wood, cream, soft blue or other muted tones can create a nursery that feels whimsical without becoming overly themed.
It also gives the room somewhere to go as your child gets older. The crib can become a bed and the baby accessories can disappear, while planets, stars and moons can still feel completely at home.
How to Arrange Space Wall Decals
Before you start sticking planets all over the wall, decide where you want the eye to go first. Usually, that means choosing one larger element or a group of larger decals as the focal point.
From there, add medium and smaller pieces around it. Vary the height and spacing rather than creating obvious rows, and remember that you don’t have to use every decal on one wall. A few pieces can continue onto an adjoining wall or another area of the room to make the theme feel more connected.
For a lighter look, spread the decals farther apart and allow more of the original wall to show. If your little astronaut wants to feel completely surrounded by space, bring the elements closer together and add more stars between the larger designs.
There is no single correct layout. The goal is to create movement and balance rather than perfect symmetry.
What Colors Work Best in a Space-Themed Bedroom?
Navy and blue are natural choices for a space room, but they’re definitely not the only ones.
For a classic look, combine blue with white, gray and natural wood. For something warmer, introduce tan, camel, rust or walnut. A softer nursery can use cream, pale blue and warm wood, while a more modern space room can lean into neutral planets against warm white or beige walls.
You can also let the wall decor establish the palette. Choose two or three colors from your planets or rockets and repeat them in bedding, a rug, storage baskets or one or two accessories. The room will feel coordinated without needing a matching space-themed version of everything.
How Do You Create a Space Room Without Making It Too Themed?
This is where restraint helps.
If the walls are doing something exciting, the bedding doesn’t also need rockets. The rug doesn’t need planets. The curtains don’t need stars. And the lamp probably doesn’t need to look like an astronaut.
Choose where you want the theme to live and let the rest of the room support it.
For example, create a full celestial wall with planets, rockets and stars, then use simple bedding, natural wood furniture and solid-color textiles. You’ll still immediately know it’s a space room, but it won’t feel like every item was purchased from the same themed collection.
It also makes the room much easier to update as your child grows.
Space-Themed Bedroom Ideas for Different Ages
For a nursery, keep the palette softer and the layout a little simpler. One moon, a smaller group of planets or a scattering of stars can create plenty of interest without overwhelming the room.
Toddlers and younger kids may love more of a story. Add rockets, astronauts and planets around a play area or bed and create a wall that feels like something is actually happening.
For older kids, consider moving away from the cuter elements and leaning into planets, constellations, moons and stars. A celestial room can feel surprisingly sophisticated when the palette and surrounding furniture grow up with it.
That flexibility is one of the reasons space is such a great theme for a child’s room. Their fascination with rockets may change, but the sky has a pretty long shelf life.
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 planets, a large moon or spaceships. Add smaller stars or celestial elements around it, then repeat a few of the colors from the wall decor in the bedding, rug or accessories. Keeping some of the room simple prevents the theme from becoming overwhelming.
What colors are good for a space-themed bedroom?
Blue, navy, white and gray are classic choices, but a space room can also use cream, beige, natural wood, rust, tan or other warm neutrals. The best palette depends on whether you want the room to feel bold, playful, soft or more sophisticated.
Where should you put planet wall decals?
Planet wall decals work well behind a bed or crib, above a dresser, around a reading nook or across a large feature wall. Arrange them at varying heights and leave some open space between designs so they appear to float rather than sit in a row.
Can you put star decals on the ceiling?
Extending some stars from the wall onto the ceiling can make a space-themed room feel more immersive. Always make sure the surface is appropriate for the decal material and follow the installation recommendations for your particular product.
Is a space theme good for a nursery?
Yes. A space nursery can be as soft or colorful as you want it to be. Moons, stars and planets work particularly well because they can transition beyond the baby stage, allowing you to update the furniture and accessories without necessarily changing the walls.
How can I make a space-themed room grow with my child?
Use the walls for the strongest part of the theme and keep larger furniture relatively versatile. Celestial elements such as planets, stars, moons and constellations can work for a wider range of ages than highly specific baby decor.
Are Urbanwalls space decals removable?
Urbanwalls' current space wall decals are designed to be removable from properly prepared painted walls, but they are intended for one-time use rather than being removed and reused elsewhere. The company also recommends allowing freshly painted walls to cure for 4 to 5 weeks before applying its current wall decals.
Build a Universe of Their Own
A space-themed room doesn’t have to be scientifically accurate, perfectly coordinated or filled from floor to ceiling with planets. It just needs to give your little astronaut somewhere for their imagination to take off.
Start with the part of space they love most. Maybe it’s a giant moon above the bed, planets floating across the nursery or rockets blasting toward the ceiling. Add stars and smaller details around it, then let the rest of the room stay simple enough for the design to shine.
Best of all, you’re the one creating the galaxy, so no two rooms need to look exactly alike.
