Fit Check

See it in your room
before you buy it.

That rug you're staring at? That Marketplace couch? Upload your room and the item's photo — see them together in under a minute, with an honest Buy it or Skip it verdict on size, color and style.

Check it in your room before the box arrives, not after.

Your photos are used only for this check. They go to our AI partners to run it, we never store them, and nobody else sees them.

Add both photos to run the check

Each check runs a paid AI render, so Fit Check stays limited until buying is back · plans already bought keep working · fair-use limit of 10 checks a day on every plan

How Fit Check works

1

Your room

One straight-on photo of the room the item would live in.

2

The item

The product photo — any store, any listing, even secondhand.

3

The verdict

See the furniture in your room before you buy — Buy or Skip, with the reasons in plain words.

Fit Check questions

Will this couch fit in my room?

That's exactly the question Fit Check answers. Upload your room photo and the couch's listing photo (add the listed width if you have it), and you'll see the couch in your actual room plus a size check reasoned against your real furniture — before you order anything.

How does the Fit Check work?

You upload two photos: your room and the item you're considering (the product photo from any store or listing). RoomCalm places the item into your actual room photo at realistic size and lighting, and gives you an honest Buy or Skip verdict based on three checks: size, color and style.

Does it work with Facebook Marketplace or secondhand finds?

Yes — that's where it shines. Store AR tools only work on their own catalogs. Fit Check works from any photo, so a Marketplace couch, a thrift-store dresser or an Etsy find all work the same way.

Will it tell me not to buy something?

Yes, honestly. If the size, color or style doesn't work for your room, the verdict is Skip — with the reason in plain words, and a couple of alternatives that would work instead. A fit check that always says buy would be useless.

Is Fit Check free?

Fit Check comes with every paid plan, and your first purchase is covered by our 14-day money-back guarantee. On the $9 pack each check uses one credit; the $15 and $30 monthly plans include checks without using credits. Every plan has a fair-use limit of 10 checks a day. Your first full room redesign is still free on the home page — no sign-up needed.

What happens to my photos?

They're sent securely to our AI partners (OpenRouter and Google AI) to make the preview and the verdict — that's the only thing they're used for. We don't store them, we don't publish them, and we don't keep your results afterwards.

How accurate is it?

The preview is an AI edit of your real photo, made at realistic scale and lighting — it's a strong visual guide, not a millimeter measurement. Adding the item's listed size makes the check much sharper. For built-ins and exact clearances, we still recommend a tape measure; the verdict explains its reasoning so you can judge too.
