Enter your room dimensions and furniture layout to find the right rug size — border spacing, furniture overlap, and standard sizes.
Whether it fits depends on measurements most people get wrong.
Room dimensions minus 24–36" (border) = ideal rug size
Item: Common rug sizes: 5×7, 6×9, 8×10, 9×12, 10×14
Space: Small room (10×12): 6×9 or 8×10 rug. Large room (14×18): 9×12 or 10×14 rug
Actual clear openings are usually 1–2″ smaller than the labeled size.
Your exact dimensions probably aren't "standard." Small measurement errors cause big problems — 1 inch can be the difference between fitting and getting stuck.
Verdicts are calculated by comparing all 6 item orientations against the space dimensions using verified building code standards. See our methodology

For a typical 12 × 16 living room with a sofa and two chairs, an 8 × 10 or 9 × 12 rug works best. The rug should be large enough for at least the front legs of all seating pieces to rest on it.
An 8 × 10 rug placed horizontally under a queen bed extends about 22" on each side and 12" at the foot. A 9 × 12 rug provides more coverage for larger bedrooms.
The standard design guideline is 12–18 inches of bare floor between the rug edge and the wall on all sides. In small rooms, 8–12 inches is acceptable. Wall-to-wall rug coverage makes the rug look like carpet.
