The extra two feet of length can become a work zone, a storage wall, or a calmer route around the bed. The useful answer depends on what you do every day.
Quick answer: A 10 × 12 ft room is about 3048 × 3658 mm. The three approved anchors below share the same envelope but change the strategy, so you can compare work usability against bed access and storage.
Geometry first. The RoomFeng 10 × 12 anchors are 3048 × 3658 mm. A Queen mattress is not the outside footprint of its frame; reserve additional depth for the frame, chair pull-out, and wardrobe doors.
The light-route plan protects an entry path, the wardrobe-wall plan concentrates storage, and the balanced plan includes a Taiwan 5-ft bed with desk and wardrobe.
Trade-off: A clearer central route may require one-sided bed access; a larger storage wall narrows the work approach.
Before you move anything
The records assume a rectangular room with the documented door and window scenarios. Confirm your actual wall positions before buying. Measure the outside of every bed frame, desk, wardrobe and chair operating zone. A mattress preset is only an anchor.
