A 300 × 400 cm rug measures three metres by four metres and covers 12 square metres. That is a generous footprint, but the right fit depends on the furniture arrangement and circulation around it.
Measure a clear rectangle on the floor with a tape measure. Use removable markers that are safe for your floor finish to mark its corners. Check the shape in both orientations: a four-metre width may suit a broad sofa arrangement, while a four-metre length may work better along the room.
Write down the sofa width and depth, then include any chairs and side tables you want the rug to connect. Decide whether you want all furniture legs on the rug or just the front legs of the main seating. Both can work; what matters is that the arrangement feels deliberate and the furniture sits securely.
A 280 cm sofa centred along a 400 cm rug edge leaves 60 cm on either side before allowing for other furniture. Centred along the 300 cm edge, it leaves only 10 cm on each side. The same rug can therefore look very different when rotated.
Check walking routes, door swings, hearths and floor vents. Keep the rug clear of any appliance or fireplace safety zone. Make sure doors can move over the rug and underlay together.
In an open-plan room, a large rug can define the living area without needing to cover the entire floor. If the dining area is nearby, measure it separately: dining chairs need space on the rug when pulled out, not just when tucked under the table.
A one-off handmade rug may have slightly different proportions from a standard retail size. Check the listed dimensions rather than relying on “large” or “oversized”. Explore large rugs and extra large rugs. If the proportions still do not work, ask about a custom size for an eligible design.
