What for

For the questions that come up before every move and every furniture purchase

Wall 340 · sofa 260

Does a sofa that size really fit along this wall?

Put it there at true scale. You see at once whether it fits and what still has room next to it.

tight · 52 cm

How much room is left between the wardrobe and the bed?

The gap is shown in centimetres right beside it. Below 60 cm it turns red, because that is where it gets tight.

Passage 85 cm

Can I still get past the dining table with the chairs out?

Put the chairs on the plan too, pulled out a little. Then you see whether the passage remains.

Variant A · B · C

Does the room work as a child's bedroom?

Bed, wardrobe, desk: try several variants side by side without moving a single piece of furniture.

PAX 100 × 58

Does the new wardrobe still fit next to the bed?

Popular Ikea models come with their real outer dimensions. Everything else you type in, in centimetres.

Where does everything go in the new flat?

Record your furniture once and place it in the new floor plan. A tick shows what already has its spot.

How it works

Three steps and you know whether it fits

Upload your floor plan

You already have the plan: from the listing, from your landlord or as a photo. Drag it in, pick the file or paste it from the clipboard.

Measure one wall

Click the two ends of a distance whose length you know and type in the centimetres. That is all the setup there is: from now on the scale is right.

Place your furniture

Pick furniture from the library or type in your own dimensions, then move and rotate. The gap to the nearest piece is always shown beside it.

That is all there is to it. You already have the plan, and one wall is quickly measured.

Clarity instead of furniture Tetris

Shove, measure, shove it back again: you do that here on the plan instead of in your living room. And unlike other room planners, Stellprobe does not ask for a 3D model of your home. This is not about interior design but about one question: does it fit, and can you still get past?

Outer dimensions

A “160 × 200” bed is not 160 wide

For beds, furniture shops quote the mattress. On the plan, what counts is the frame. Plan with the catalogue figure and the passage next to the wardrobe comes out 16 cm too generous, and you only notice while assembling it.

Centimetres like these decide whether it fits. That is why Stellprobe comes with 47 popular Ikea models and their outer dimensions, each looked up on ikea.com and dated.

Together

Whoever moves in with you plans with you

Share the flat with your partner, your flatmate or your parents, and you both move things around on the same plan, from the sofa or on the go. If you work at the same time, no idea gets lost: whoever saves later keeps their version as a variant of its own.

Also

Simple does not mean imprecise

A corner sofa is not a rectangle

Corner sofas, corner kitchens and corner desks sit on the plan as a real L-shape, chaise on the left or on the right. So you do not give away space the piece does not even need.

Will it go through the door?

With the measuring tool you measure any distance on the plan in centimetres: door width, alcove, room for the pulled-out chair.

Several floors, several ideas

As many floor plans and variants per home as you like. You set the scale once per floor plan, and after that it is right for every idea.

Take it to the furniture shop

Your plan as an A4 PDF at a scale such as 1:50, ready to check with a ruler, with numbered furniture and a furniture list.

FAQ

Before you ask

What does Stellprobe cost?

Stellprobe is currently free. There are no ads and no analytics tools.

Which floor plans work?

Any image: a photo, a scan, or a screenshot from the listing or from a PDF. All that matters is that the plan is seen straight from above and that you know one distance on it.

My plan has no dimensions. Does it still work?

Yes. Measure one wall on site and use it as your reference. For a first estimate an interior door will do: it is usually 80 to 90 cm wide.

How accurate is the result?

As accurate as your plan and your reference distance. The longer the measured distance, the more accurate the scale. With the measuring tool you can check any other wall.

Do I need 3D software or an installation?

No. Stellprobe runs in the browser, on a laptop, on a tablet and, at a pinch, on a phone. You plan from above, just like on the floor plan.

Why do I have to wait for approval?

Stellprobe is a small project and we approve new accounts by hand, usually within a day. With an invitation link from someone who is already in, it is immediate.

Who can see my floor plan?

Only you and the people you share a project with. Our admin view shows us numbers only, such as how many projects an account has, not your plans. You can delete projects yourself at any time. Details are in the privacy policy.

Put it there first. On the plan.

A sofa that does not fit costs nerves, money and a Saturday. Trying it on the plan costs a few minutes.
