15 Space Bedroom Ideas for an Out-of-This-World Kid's Room
A space-themed bedroom can turn an everyday room into somewhere that feels full of adventure. Planets, rockets, astronauts and distant stars give children plenty to imagine, but creating a beautiful space bedroom does not mean covering every surface with galaxies and glow-in-the-dark decorations.
The most successful space bedrooms balance imagination with the practical things a child's room still needs: comfortable furniture, useful storage, room to play and a design that will not immediately feel too young as their interests change.
Whether you are planning a complete room makeover or simply want to introduce a few cosmic details, these space bedroom ideas will help you create a room that feels playful, stylish and thoughtfully put together. Removable-style Space Wall Decals can also make it easier to introduce planets, rockets and astronauts without committing to a permanent themed wall.
1. Create a Space-Themed Feature Wall
If you want the space theme to make an immediate impression, start with one feature wall rather than trying to decorate the entire bedroom.
The wall behind the bed is often a natural choice. A collection of planets, stars, rockets or astronauts can create a focal point while allowing the remaining walls to stay relatively simple. This gives the room a clear theme without making it visually overwhelming.
For a younger child's room, colourful planets and friendly astronaut illustrations can create a playful atmosphere. For an older child, consider a more restrained combination of planets, stars and deeper colours.
Our Space Wall Decals collection can be used to build this kind of feature wall while keeping the surrounding furniture and décor comparatively neutral.
2. Build the Room Around a Cosmic Colour Palette
Dark navy may be the colour most commonly associated with space, but it does not have to dominate the entire bedroom.
Instead, use deeper shades selectively and balance them with softer colours. Navy, muted blue, charcoal or dusty purple can work beautifully alongside warm white, pale grey, natural timber and cream.
If the bedroom is small or receives limited natural light, keeping most of the walls light can help the room feel brighter. Introduce darker cosmic colours through bedding, cushions, artwork and smaller decorative details instead.
You can also take inspiration directly from the planets. Rusty orange, sandy beige, muted red and soft blue can introduce warmth into a scheme that might otherwise feel too cold.
3. Turn the Bed Area Into a Mini Solar System
The space directly around the bed offers another opportunity to create a strong theme without decorating the entire room.
Position planets and stars around the headboard or along the wall beside the bed to create the impression of a small solar system. A design such as a Watercolour Solar System Space Wall Decal can introduce the theme while retaining a softer, more decorative appearance.
Keep the bedding relatively simple if the wall itself contains plenty of detail. Plain navy, cream, grey or muted blue bedding allows the wall design to remain the main feature rather than competing with another busy pattern.
This approach works particularly well when you want the bedroom to feel imaginative during the day but still calm enough for bedtime.
4. Create an Astronaut Adventure Bedroom
For children fascinated by astronauts and space exploration, build the room around the idea of travelling through space rather than simply decorating it with stars.
An astronaut floating among planets can become the starting point for the entire design. A Solar System Astronaut Wall Decal, for example, can establish the theme while other elements remain understated.
Add small supporting details rather than filling the room with novelty décor. A few space books on an accessible shelf, a model rocket, a moon-shaped cushion or simple star details can reinforce the story without making the bedroom feel cluttered.
This is also a useful way to create a bedroom that encourages imagination. The room becomes more than somewhere decorated with planets; it can feel like the setting for the child's own space adventures.
5. Design a Space Bedroom That Feels Calm at Night
A children's bedroom still needs to work as a restful sleeping space, even when the theme is adventurous.
If the wall décor is colourful, balance it with simple furniture and softer textiles. Warm white walls, natural wood, cream rugs and understated bedding can prevent rockets, planets and stars from becoming visually overwhelming.
Lighting also makes a noticeable difference. Rather than relying entirely on a bright ceiling light, introduce a softer bedside or reading light for the evening. Any lighting used in a child's bedroom should be positioned and installed appropriately, with cables and electrical fittings kept safely managed.
The result can still feel unmistakably space-themed while becoming noticeably calmer when it is time to wind down.
6. Create a Rocket Launch Corner
Not every themed detail needs to sit around the bed. If there is an unused corner of the bedroom, turn it into a small imaginative play area.
A rocket and planet design, such as the Rocket Planet Meteor Space Theme Wall Decal, can visually separate the area from the sleeping zone. Add a small rug and age-appropriate toy storage nearby so the corner has a practical purpose as well as a decorative one.
This can be especially useful in bedrooms where children both sleep and play. Creating visual zones gives different parts of the room a purpose without requiring physical dividers or additional furniture.

7. Use Watercolour Space Décor for a Softer Look
Space bedrooms do not have to be dark, dramatic or heavily saturated. Watercolour-style planets can create a much gentler interpretation of the theme.
Look for muted blues, dusty pinks, soft greys, beige and subtle touches of orange. Combined with pale timber furniture and warm neutral textiles, these colours can make a space-themed room feel surprisingly calm and contemporary.
This approach is particularly useful if you like the idea of a themed bedroom but still want it to coordinate with the rest of your home's interior style.
Instead of adding numerous space accessories, allow the wall décor to communicate most of the theme. A few carefully chosen details will usually feel more considered than filling shelves and furniture with matching decorations.
8. Bring the Solar System Into a Small Bedroom
A small bedroom can still have a strong space theme, but careful editing becomes more important when floor and wall space are limited.
Choose one main decorative area and leave some visual breathing room around it. A Moon Stars and Planets Wall Decal can introduce the solar-system theme without requiring additional furniture or taking up valuable floor space.
Keep larger pieces of furniture relatively simple and prioritise storage that suits the available space. Where appropriate for the furniture and manufacturer's instructions, securing suitable storage furniture to the wall can also help create a safer and more organised children's room.
Light walls and a restrained colour palette can make the bedroom feel more open, while smaller areas of navy, blue or charcoal provide enough contrast to maintain the cosmic theme.
Many of the same principles used in our 15 Small Nursery Ideas for Tiny Spaces can be adapted to children's bedrooms too: use the available walls thoughtfully, avoid unnecessary clutter and let a few carefully chosen features make the biggest impact.
9. Create a Starry Reading Corner
A quiet reading corner can give the space theme another purpose beyond decoration. Instead of repeating the main feature wall, use a smaller area of stars, moons or planets to create a cosy corner that feels slightly separate from the rest of the bedroom.
Start with a comfortable floor cushion, child-sized chair or another age-appropriate seating option, then keep a small selection of books within easy reach. Space and astronomy books can reinforce the theme naturally without requiring additional decorative accessories.
A few stars positioned around the reading area can help define the corner while leaving enough blank wall space to keep it calm. If the bedroom already has a dramatic feature wall, this secondary area should usually be simpler.
The aim is to create somewhere that encourages quiet time while still feeling connected to the child's interest in space.
10. Combine Space Décor With Natural Wood
One of the easiest ways to stop a space bedroom from feeling overly themed is to introduce plenty of natural materials.
Light oak, pine and other warm timber finishes provide a softer contrast against navy, blue, grey and black. A simple wooden bed, shelving or storage unit can make colourful planets and rockets feel more integrated into the room rather than appearing like temporary themed decorations.
Natural textures can help too. Consider a woven basket, cotton bedding or a simple textured rug rather than trying to make every item fit the space theme.
This balance is particularly useful if you want the room to remain stylish as your child grows. The furniture forms a timeless foundation while the more playful wall décor can evolve separately.
11. Make Planets the Main Theme Instead of Rockets
Rockets and astronauts are not the only way to create a space bedroom. Building the design primarily around planets can result in a room that feels colourful, educational and slightly more timeless.
A design such as a Cartoon Universe Planet Wall Decal can establish the theme without requiring every other element in the bedroom to reference space.
Use the colours within the planets as inspiration for smaller accents around the room. A muted orange cushion, blue throw or warm beige rug can subtly connect the furniture and textiles to the wall design.
This approach creates cohesion without relying on perfectly matching accessories, and it gives the bedroom a more collected, individual appearance.
12. Create a Space Bedroom for an Older Child
A child's interest in space does not necessarily disappear as they get older, but the way the theme is presented can mature with them.
Instead of cartoon-style accessories throughout the room, focus on a more restrained palette and a few stronger visual details. Deep blue, charcoal, warm white and natural timber can create a more grown-up foundation, while planets or a solar-system design preserve the child's interest in astronomy.
Simple bedding, practical storage and a suitable desk area can make the room work for everyday life as well as reflect their personality.
If you are planning the wider room rather than only the space theme, our 15 Kid's Bedroom Ideas for Stylish and Functional Spaces includes additional ideas for balancing imaginative décor with practical bedroom design.
13. Add Space Personality Without Replacing the Furniture
A complete bedroom renovation is not necessary simply because your child has developed a new interest.
If the existing bed, drawers and storage still work well, keep them and change the elements around them. Wall décor, bedding, cushions and a few carefully chosen accessories can significantly change the atmosphere of the room without replacing its largest pieces.
This is where removable-style Space Wall Decals can be particularly useful. They allow the walls to carry much of the theme while the more expensive furniture remains versatile.
Keeping the foundation simple also makes future changes easier. If your child's interests eventually move from rockets to something completely different, the entire bedroom does not need to be redesigned.
14. Personalise the Room Around What Your Child Loves About Space
Not every child who loves space is interested in exactly the same things. One may be fascinated by astronauts, another by rockets, while another might spend hours learning about planets and the solar system.
Use that interest to decide which element should become the focus of the bedroom.
If rockets are the favourite, build the main decorative area around a launch or exploration theme. If planets are the attraction, let a solar-system wall become the centrepiece. For a child interested in astronauts, a single adventurous astronaut scene may be enough to give the whole bedroom its identity.
Designing around a genuine interest tends to create a room that feels more personal than simply purchasing a complete set of matching space-themed accessories.
15. Design the Space Bedroom So It Can Evolve
Children's interests and tastes change, so it helps to think beyond how the bedroom looks immediately after decorating it.
Keep the larger and more expensive elements relatively adaptable. A timeless bed, practical storage and simple shelving can continue working even if the decorative theme changes later.
Then allow the walls, textiles and smaller accessories to carry most of the space theme. This makes it much easier to simplify or update the room as your child grows.
For example, a younger child's colourful rocket bedroom could gradually become a more understated astronomy-inspired room simply by changing some of the playful accessories while retaining the same furniture.
A flexible approach allows the bedroom to celebrate what your child loves now without making every design decision dependent on one theme.
Common Space Bedroom Decorating Mistakes
Using Too Many Space-Themed Items
When the bedding, curtains, rug, lamps, furniture and walls all feature planets or rockets, the theme can quickly become overwhelming. Choose a few strong space elements and give them room to stand out.
Making the Entire Room Too Dark
Navy and charcoal can work beautifully in a space bedroom, but using dark colours across every wall may make a smaller room feel enclosed. Balance deeper tones with warm whites, lighter furniture or natural timber.
Forgetting About Everyday Function
A beautiful feature wall cannot compensate for a room that lacks useful storage or comfortable areas for sleeping, reading and playing. Plan the practical layout first and decorate around it.
Buying Furniture Only for the Theme
Novelty furniture can be difficult to incorporate once a child's interests change. Keeping larger furniture versatile and expressing the theme through easier-to-update elements can give the bedroom greater longevity.
Trying to Fill Every Empty Wall
Blank space is part of good room design. Leaving some walls or sections undecorated can make planets, astronauts and rockets more noticeable rather than less.
Frequently Asked Questions About Space Bedrooms
What colours work best for a space-themed bedroom?
Navy, dusty blue, charcoal and muted purple are natural choices, but they work particularly well when balanced with warm white, cream, beige and natural wood. Planet-inspired shades such as rust, ochre and muted red can also add warmth.
How can I create a space bedroom without painting the walls?
You can introduce the theme through wall decals, bedding, artwork and smaller accessories. Exploring Space Wall Decals can be a useful starting point if you want planets, rockets or astronauts to become the main visual feature without relying on a painted mural.
How do I make a small bedroom look space-themed?
Concentrate the theme on one wall or a smaller decorative area rather than filling the room with accessories. Keep larger surfaces relatively light, use practical storage and allow the wall décor to provide most of the visual impact.
Can a space bedroom work for an older child?
Yes. Use a more restrained colour palette, simpler textiles and less cartoon-like styling. Planets, astronomy-inspired details and solar-system imagery can preserve the space theme while giving the room a more mature appearance.
How can I stop a themed bedroom from looking too busy?
Choose one or two focal points and keep the surrounding furniture and textiles simpler. Repeating a small selection of colours throughout the room can also make different elements feel connected without everything needing to match.
Create a Space Bedroom They Can Make Their Own
A memorable space bedroom does not need to look like a complete spaceship. Often, the most effective rooms combine a few imaginative details with comfortable furniture, practical storage and enough simplicity to let the child's personality come through.
Whether they dream about astronauts, rockets, distant planets or exploring the solar system, start with the part of space that fascinates them most and build the room around it.
If the walls are where you want the adventure to begin, explore our Space Wall Decals collection for planets, astronauts, rockets and solar-system designs that can help transform an ordinary wall into part of their own little universe.
