Wardrobe listings give width, depth and height. They rarely say how much floor you need in front to actually open the thing.

Clearance by door type

DoorsClear space in frontWorth knowing
Two hinged (50 cm each)About 50 cmEach door swings out its own width
SlidingAlmost noneOnly half the wardrobe is open at a time
DrawersDrawer depth + standing roomA fully pulled drawer still needs someone behind it
Bi-foldAbout half a door's widthFolding panels stick out less than hinged ones

These are rough figures. The installation drawing that comes with the product usually has the real ones. If there are drawers, measure them separately; they often stick out further than the doors.

A case where the doors weren't the issue

Queen bed150×200Wardrobe100×60ShelfDOOR 80300300
CaseA 300 × 300 cm room. 153 cm of clear floor in front of the wardrobe.

In this room there's 153 cm in front of the wardrobe, enough for any door type. You just can't get there. The gap between the bed's corner and the shelf is 33 cm across, and that's the only way in.

Sliding the shelf all the way to the right wall only widened it to 58 cm. Taking the shelf out entirely finally opened a path to the wardrobe.

Even then the planner still says Not found, because of a 28 cm gap between the headboard and the side of the wardrobe at the far end of the room. Nobody needs to walk through there, so this is one of the cases where the route check is stricter than real life.

Turning the wardrobe 90° against the right wall makes its doors face the bed with 90 cm in front, which still leaves 40 cm with the doors open. That version is in the plan details box.

Check the ceiling before assembly

Tall wardrobes are often built lying down and then tipped upright, and the side panel's diagonal has to clear the ceiling on the way up. A wardrobe 200 cm tall and 60 cm deep has a diagonal of roughly 209 cm. Fine under a 230 cm ceiling; not necessarily fine if there's crown molding or a light fixture hanging down.
