How to Design a Room
Four steps from an empty room to a styled space you can see in 3D
1. Set your real room
Enter your room's dimensions, or snap a photo to capture it, so everything you try is sized to your actual space.
2. Add & arrange furniture
Drag in from 600+ to-scale furnishings, then move and rotate pieces to test how the room comes together.
3. Try styles & finishes
Swap colors, change flooring, and resize or recolor individual pieces until the look is yours.
4. See it in 3D
Switch to 3D and walk the room from any angle to know how it really looks before you buy a thing.
Design the room before you spend on it
Looking for interior design software usually means you care how a room will look and feel — not just its measurements. You want to try a sofa, a rug, a wall color, a whole layout, and actually see it before you buy. The problem is that pro design suites are expensive and built for designers, and mood boards never tell you whether things truly fit.
RoomSketch3D lets you design in your real room dimensions: arrange 600+ furnishings, recolor and resize them, set finishes, and see it all in 3D before you spend a cent. It looks good and it fits — because everything is to scale.
Who designs interiors with RoomSketch3D
Anyone who wants to see a room come together before committing to it.
Decorating a room
Refreshing a living room or bedroom? Test layouts, colors, and pieces in your real space before you commit.
Furniture shopping
Eyeing a new sofa or bed? Drop it in to scale and see if it fits, fills the space, and matches what you own.
Rearranging what you have
Not buying anything — just want a fresh layout? Move everything virtually before you move it for real.
Students & home stagers
Mock up rooms quickly, present concepts in 3D, and export clean images for clients or coursework.
See it in action: restyle your living room before buying a sofa
Shop with confidence — starting from the Cozy Living Room template.
- 1
Start from the template. Open the Cozy Living Room — a 14×16 ft room with a sofa, TV setup, and conversation area.
- 2
Match your space. Set the dimensions to your real living room so everything you try is sized correctly.
- 3
Try the new sofa. Swap in a sofa at the size you're considering and recolor it to test fabrics.
- 4
Style around it. Add a rug, set the flooring, and try a wall color to see the whole scheme together.
- 5
Check it lives well. Use the tape measure and Flow Check to confirm walkways and spacing feel right.
- 6
Decide and shop. View it in 3D, then export an image to take to the store — you already know it works.
Everything you need to style a room
The pieces, the finishes, and the 3D view that make a design decision easy.
600+ furnishings & décor
Style with to-scale furniture, lighting, rugs, mirrors, fireplaces, plants, and more — including configurable pieces.
Make every piece yours
Edit items individually — change a sofa's color, a table's size and shape, a lamp's finish — to match your scheme.
Color & flooring
Set wall colors and choose per-room flooring — hardwood tones, tile, and more — to build a complete look.
Realistic 3D walk-through
See your design in 3D from any angle and walk through it, so the finished feel is no surprise.
It fits, not just looks good
Everything is to scale, and Flow Check flags tight spacing — so your styled room is also comfortable to live in.
Share & take it shopping
Export images or share a link — take your plan to the store, or send it to a partner or client for sign-off.
Start your room design however you like
Begin from a photo of your room, a traced plan, a template, or by drawing the space yourself.
Snap a photo
Take a photo of your room and let the app turn it into an editable room design for you — no drawing required to begin.
Trace an image
Already have a room design or a rough sketch? Import the image and trace over it — corners snap into place as you go.
Draw any shape
Draw walls freehand — rectangular, L-shaped, angled, or fully custom and round room shapes are all fair game.
Start from a template
Begin with a ready-made template and adapt it into your own room design in minutes.
Scan it on iPhone
On iPhone, use AR Scan to capture a room's real dimensions just by walking around it.
Why design it before you buy
- See how furniture looks in your actual room before you buy
- Test colors, finishes, and layouts risk-free
- Confirm pieces fit and leave comfortable walkways
- Compare two looks side by side before deciding
- Take a clear plan to the store or share it for a second opinion
Interior design software vs. a designer vs. mood boards
Where designing it yourself in 3D fits — and where it doesn't.
Hiring a designer
Brings a trained eye and sourcing, but costs a premium — a lot to spend just to test a layout or a single new piece.
Best for: a full, expert makeover
Mood boards
Great for inspiration, but they never tell you whether a piece fits your room or how the layout actually works.
Best for: gathering ideas
RoomSketch3D
Design in your real room, to scale, and see it in 3D before you buy. Honest note: it's clear, useful 3D — not a designer's taste or cinematic photo-realism.
Best for: confident DIY decorating
