How do you choose the right rug size for a room?
Answer
Size up, not down: in a living room the rug should sit under at least the front legs of every seat in the group; under a bed it should extend 45–60 cm beyond each side; in a dining room chair legs must stay on the rug when pulled out. When in doubt, buy the larger size.
Rugs are the most common sizing failure in home design — almost everyone buys too small, and a small rug doesn't look like a modest choice; it looks like a mistake. Three rooms, three rules.
Living room: anchor the whole group. The rug should reach under the front legs of the sofa and every chair, unifying the seating circle into one zone. All-four-legs-on is the luxury version; front-legs-only is the standard; nothing-on is why the room reads choppy. A 160 × 230 cm rug suits a small seating group, but most living rooms want 200 × 300 cm — the size people hesitate at and rarely regret.
Bedroom: extend past the bed. The rug should stretch 45–60 cm beyond each side and the foot of the bed, so bare feet land on it every morning. A runner on each side is the workable compromise in tight rooms; a rug narrower than the nightstands is not a compromise, it's a doormat.
Dining room: respect the chair pull. Chairs stay on the rug even when pulled out for someone to sit — which means the rug extends at least 60 cm beyond the table on all sides. A rug that fails this test turns every dinner into a teetering event.
Two universals. First, tape the footprint on the floor before ordering: an outline of painter's tape beats any size chart. Second, leave a border of bare floor around the rug's edge — 30–45 cm of visible flooring keeps the rug reading as a layer, not wall-to-wall carpet.
