Independent pre-purchase fit check / 01

The sofa fits the wall.
Can it reach it?

The purchase checkpoint / 01

Four questions before one expensive yes.

A product page tells you the furniture size. RoomFact compares it with the space it will occupy and the route it must survive, without asking you to build a 3D project first.

PlacementFull item width against the usable wall

Walking spaceOpen floor left in front of the item

OpeningClear width and height at the tightest frame

Delivery routeTurns, stairs, landings, and elevators still ahead

The working index

Start with the number you actually need.

Each calculator has one job, one short measurement list, and a result that names the assumption worth checking next.

01furniture

Sofa size calculator

See how much wall and walking space a sofa will leave in your room.

02fit

Doorway furniture fit checker

Check whether a rigid piece of furniture can pass through the clear doorway.

View all 22 planning tools

Copy the outside dimensions

Use the unboxed width, depth, and height from the product page.

Measure the real constraints

Check the usable wall, open floor, and tightest route point.

Read pass, check, or pause

See the exact bottleneck, then confirm it physically before checkout.

Working rule

Measure first. Spend second.

Every tool starts with a physical question, shows the working assumptions, and names the constraint that deserves another look.

A compact apartment where furniture placement and walking paths matter — Small rooms make every outside dimension count.

After the fit check

Test where it could go.

Use the private 2D planner when you need to compare positions, door swings, or several real furniture footprints. It is a scale-checking tool, not a photorealistic design studio.

Field notes

Where the calculator stops.

Practical guides cover the details a formula cannot see: awkward corners, furniture construction, delivery routes, material behavior, and real-room tradeoffs.
