Choosing a rug: size, material, placement

Better too large than too small

A rug should form a zone, not decorate a surface. For that, the furniture has to be in contact with it.

The minimum standard: the front legs of all seating stand on it. It looks more generous when the entire seating group fits on it with all its legs. What never works is a rug that is narrower than the sofa – then it looks like a coaster.

In the dining room a rule of its own applies: the rug must be large enough for the chairs to stand on it completely even when pushed back. As a guideline, that means around 75 cm (29.5 in) of overhang beyond the edge of the table, on all sides. If you go below this value, the back legs tip over the edge every time someone gets up.

It helps to mark out the planned size on the floor with masking tape or a string before buying. Areas almost always look smaller on the floor than the number on the folding rule suggests.

Round or rectangular

Rectangular rugs follow the room and calm it. Round rugs break it up and work where something round is already present – a round table, a bay window, a freestanding seating group.

In narrow rooms a round rug usually looks lost because it ignores the existing geometry. As a rule of thumb: the more clearly rectangular the floor plan, the more likely the rectangular form wins.

The material shapes everyday use

Wool is the most versatile of the common natural fibres: thanks to its natural grease content it absorbs stains more slowly, it is warm underfoot, flame-retardant, and recovers over time after pressure marks. New wool rugs shed noticeably in the first weeks; this settles down with regular vacuuming. Wool does not tolerate heat and harsh cleaners.

Plant fibres such as jute, sisal or coir are robust and usually cheaper. In pure abrasion resistance some of them are even superior to wool, which makes them interesting for hallways and heavily used paths. On the other hand, they are hard underfoot and sensitive to wetness: moisture leaves rings and can make the fibre buckle. For areas used barefoot, they are rarely the first choice.

Synthetic fibres such as polypropylene, polyester or polyamide are easy to care for, lightfast and insensitive to moisture, and usually considerably cheaper too. It is not true that they necessarily look flat – tufted synthetic rugs are often designed precisely with a high-low relief of cut and loop pile and therefore have a lot of texture. The difference lies elsewhere: wool ages more beautifully, feels different and buffers moisture; synthetic fibre stays unchanged for longer, is more forgiving and is more prone to static.

There is no single best fibre across the board. The more sensible question is what the rug has to withstand: children, animals and dining areas argue for easy-care fibres, a quiet living area for wool.

Woven, tufted or knotted

Besides the fibre, it is worth looking at the method of manufacture, because it explains large price differences between seemingly similar rugs.

Woven rugs are made from crossing warp and weft threads. They are flat, light and often reversible – a good choice where doors close just above the floor.

Tufted rugs are made by punching yarn into a backing fabric and fixing it at the back with a coating. This is the most common and most economical method; it allows dense pile and sculpted patterns. Here the quality of the backing coating often determines durability more than the fibre itself.

Hand-knotted rugs consist of knots tied individually around the warp threads. They are the most laborious and the most expensive, but with good care last for decades and can be repaired. Signs of genuine handwork are small irregularities in the pattern and a back on which the pattern shows clearly.

Pile: short almost always wins

Short-pile rugs are easier to clean, chairs can be rolled over them and they take on fewer permanent indentations. High pile is more pleasant underfoot, but in living areas with doors, chairs and everyday life it is usually the less practical route.

In the bedroom next to the bed this is reversed – there, softness counts for more than ease of care.

More important than the pile height alone is the density. A densely worked pile springs back; a loosely set one lies flat in walkways and stays that way. A simple test: if you brush the pile against the grain and see a lot of backing fabric, the rug is thinly tufted.

What is often forgotten

A non-slip underlay. It keeps the rug in place, protects the floor and extends the lifespan, because the fibres do not rub over the surface beneath with every step. On fitted carpet a different underlay is needed than on parquet or tiles.

And the door clearance. A thick rug in front of a door that closes just above the floor is a daily annoyance. Measure the gap between the bottom edge of the door leaf and the floor, before the pile height is decided.

Then there is light. Direct sun noticeably bleaches natural fibres. Occasionally turning the rug through 180 degrees distributes fading and wear marks more evenly.
