The room has to keep working
It is frustrating to buy a beautiful table and then turn sideways every time you pass it. Start with the route from the door to your usual seat. That everyday movement deserves as much attention as the photograph of the room.
Footprint is only the beginning
A footprint is the space furniture takes up when viewed from above. Mark the proposed width and depth with removable paper. Then include a drawer or door opening, nearby plugs and the place your feet normally rest. The listed dimensions alone do not answer those questions.
Rehearse an ordinary evening
Leave the paper outline in place while using the room. Reach for a cup, move a chair and open nearby storage. If the outline gets in the way, adjust the position or size now. Check the assembled dimensions and the delivery route as separate measurements.
Keep what makes the room easier
Choose the smaller piece if it holds what you actually need and keeps the route comfortable. A shelf can help only when its contents are reachable. The IKEA room collection is a starting point for formats, not evidence that any pictured arrangement fits your home.
Sources & method
Reference: IKEA Interior Design service, “How to measure”, covering room dimensions, openings, fixed obstructions and door swings. It supports measuring the room around the furniture rather than relying on a room photograph.
Method: mark the candidate’s footprint and rehearse door, drawer and walking movements; check the delivery route separately. The paper-outline exercise is editorial guidance, not a measured installation or a guarantee that a particular item fits.

Measure the path into the room as well as the footprint
A floor plan misses doors, drawers and delivery obstacles.
Mark the item’s stated footprint on the floor with removable markers. Add the space needed for doors, drawers and someone sitting or standing beside it. Then measure the delivery route: doorway, corridor turn, lift or stair landing where relevant. Check whether the supplied dimensions refer to the assembled product or the package, and whether assembly inside the room is expected.
Compare the room in its normal occupied state.
For a hypothetical desk 60 cm deep, the usable space also includes the chair and the movement behind it. Rather than inventing a universal clearance, test your own chair and route through the room. Make sure the item does not block ventilation, access or required safety equipment. A compact product is useful only if the rest of the room still works around it.
