The most common rug mistake
The usual mistake is a rug that is too small: a little rectangle floating in the middle of the room makes the space look smaller and the furniture disconnected. Designers generally recommend going bigger than you think, so that the rug anchors the furniture group, while leaving a band of bare floor around it.
How the calculator works
Living room or bedroom: the ideal rug is the room minus a border on each side.
- Ideal length = room length − 2 × border
- Ideal width = room width − 2 × border
- Recommended size = the largest standard rug that fits within the ideal size
Dining room: the rug must hold the table and the chairs when they are pulled out.
- Ideal length = table length + 2 × chair allowance (about 24 in)
- Ideal width = table width + 2 × chair allowance
- Recommended size = the smallest standard rug that covers the ideal size
Example: living room
A 15 × 12 ft living room with an 18-inch border:
- Ideal rug: 15 − 3 = 12 ft by 12 − 3 = 9 ft
- Standard size: 9 × 12 ft, which fits exactly
Example: dining room
A 72 × 40 in table with 24 inches of chair room on each side needs at least 120 × 88 in, or 10 × 7.3 ft, so the smallest standard size that works is 8 × 10 ft, with just enough length. For a roomier feel, or if the chairs are large, go up to 9 × 12 ft.
Standard US rug sizes
| Size | Typical use |
|---|---|
| 5 × 8 ft | Small living room, under a coffee table, home office |
| 6 × 9 ft | Small seating area, twin or full bed |
| 8 × 10 ft | Most living rooms, queen bed, 4-seat dining table |
| 9 × 12 ft | Large living room, king bed, 6-seat dining table |
| 10 × 14 ft | Large rooms, 8-seat dining table |
| 12 × 15 ft | Great rooms, open-plan spaces |
Furniture placement
- All legs on: the most luxurious look, for large rooms.
- Front legs on: the most common choice, connecting sofa and chairs while letting the rug be smaller.
- Floating: only the coffee table on the rug; works in small rooms but can look sparse.
In open-plan spaces, use one rug per zone, living, dining or reading, rather than one big rug. A rug pad keeps the rug in place, protects the floor and adds comfort underfoot.
