Check if your furniture fits a bedroom layout.
A bedroom works or fails on clearances, not on floor area. The bed is placed against one wall with its nightstands, and what is left over on each side is the walking route you use every day: 2 ft is comfortable, 1.5 ft is the practical minimum, and below that you turn sideways to pass. The same applies at the foot of the bed, where you need room to open a wardrobe door or a drawer. This calculator lays out the bed at a standard 6.6 ft length, gives each nightstand a 1.7 by 1.5 ft footprint and the wardrobe a 2 ft depth, subtracts the total from the room, and reports both the leftover area and the side clearance — the clearance is the number that decides whether the layout is livable.
Bedroom Layout
Furniture footprint = bed width x 6.6 + nightstands x 2.55 + wardrobe width x 2; side clearance = (room width - bed width - nightstand width) / 2
About 18 inches to pass sideways and 24 inches to walk normally or make the bed. Under 18 inches on both sides means the bed is too big for the room.
Only just. A 6.3 ft king plus two nightstands leaves roughly 1 ft each side, which fails the comfort test. Wall-mounted shelves instead of nightstands buy back most of that.
Less than people assume. A room can show plenty of leftover area and still be unusable if all of it sits in one corner — the per-side clearance is the figure that predicts how the room feels.
