Rug Size Calculator
Buying a rug that is too small is one of the most common living-room mistakes. Enter your room dimensions and room type to see standard sizes that usually leave a sensible floor border.
Results are planning suggestions based on common retail sizes—not a guarantee for every furniture arrangement. Always confirm seating footprints and door clearances before you buy.
How it works
The tool compares your room’s short and long sides to common rug sizes, favoring options that leave roughly 12–24 inches of floor showing (slightly tighter targets in bedrooms). It ranks sizes that fit without crowding walkways.
Important limitations
Furniture scale, open-concept rooms, and custom shapes need judgment beyond this calculator. Dining rugs must also clear chair pull-out distance—measure your table.
What to do next
Measure the room with a tape, confirm sofa and table footprints, then read the rug size guide for placement rules. Use the room square footage calculator if you still need base floor area.
Frequently asked questions
- What size rug for a living room?
- Many living rooms work with 8×10 or 9×12 rugs so front legs of seating sit on the rug, with about 12–18 inches of floor border. Always measure your room and seating group.
- Should a rug go under the sofa?
- Often yes—at least the front legs. A rug that only sits in front of the sofa like a stamp usually looks undersized.
