Start with the furniture, not the floor. In a living room, the front legs of your sofa and chairs should sit on the rug; in a bedroom, the rug should extend beyond both sides of the bed so your feet land on it in the morning.
Useful reference points from our range: a 40 × 60 cm mat suits a doorway or beside a bath; 80 × 120 cm works under a coffee table or desk chair; 120 × 180 cm anchors a small seating area; 140 × 200 cm and 160 × 230 cm suit living rooms where the seating is grouped closely or the sofa's front legs sit on the rug; and 200 × 300 cm is the choice for open-plan spaces. Measure your space with painter's tape first — it is the fastest way to see the footprint before you order.
Work from your largest piece of furniture. With a three-seat sofa (roughly 200–220 cm wide), a 160 × 230 cm or 200 × 300 cm rug keeps the sofa's front legs comfortably on the rug with a border of floor still showing; smaller sizes suit reading chairs, desks and single seats. In standard rooms, leaving 20–40 cm of bare floor between the rug's edge and the walls keeps the layout balanced.
All of our Persian-style rugs are washable, which makes the larger sizes practical in dining areas and homes with pets. Browse the full range in Rugs & Bath Mats.
