A 12 m² room may hold all three pieces, but usable routes matter more than total free area.
Starting dimensions
We assume a rectangular bedroom of 3 × 4 m, or 12 m², with an 0.80 m door on the short wall. Furniture: a 1.40 × 1.90 m bed, a 1.60 × 0.60 m wardrobe and a 0.45 × 0.45 m side table. These are illustrative dimensions, not universal recommendations.
First layout
Place the bed against one long wall, the wardrobe on another available wall and the side table beside the bed. Then check three actions: entering the room, opening the wardrobe and reaching the bed without moving the table.
Free area is not the whole story
The geometric footprints are 2.66 + 0.96 + 0.2025 = 3.8225 m². Subtracting from 12 gives 8.1775 m² free on paper. But if that free area is fragmented into narrow passages, the layout may still feel cramped.
Recreate the test
Open EspacioExacto, set 300 × 400 cm, add the three objects and try different placements. Represent any recess or column before evaluating circulation.
Result: this exercise demonstrates a comparison method; it is not a unique optimal solution or an accessibility assessment.
