Enter your room dimensions, choose a rug style (rectangle, square, runner, circle, or oval), and specify your price per square foot to get back the recommended rug size, total rug area, and estimated cost. You can also set edge offsets to fine-tune how much bare floor is left around the rug — perfect for matching interior design guidelines.

Start by measuring your room's length and width, then subtract 18–24 inches (1.5–2 ft) from each side to leave a bare floor border. This border frames the rug and makes the space feel balanced. Our calculator does this math automatically once you enter your room dimensions and desired edge offset.
For a living room, choose a rug large enough so that at least the front legs of all major furniture pieces rest on it. A common guideline is to use a rug that is roughly 2 feet shorter than the shortest wall. Typical living room rugs range from 8×10 ft to 9×12 ft.
Common standard rug sizes include 2×3 ft (entry mats), 4×6 ft (small accent), 5×8 ft (medium rooms), 8×10 ft (living rooms), and 9×12 ft (large rooms). Runners typically come in widths of 2–3 ft and lengths of 6–14 ft. Round rugs range from 4 ft to 10 ft in diameter.
Kitchen runners typically measure 2 to 3 feet wide and 6 to 14 feet long. The most popular sizes are 2×6 ft, 2×8 ft, and 2.5×10 ft. Leave about 6 inches between the runner's edge and the kitchen cabinets or walls for a clean look.
Yes, layering an area rug over carpet is a popular design technique. Choose a flat-weave or low-pile rug to prevent bunching, and use a rug pad designed for carpet-to-rug use to keep it in place. Make sure the area rug is noticeably smaller than the carpeted area so the layering looks intentional.
A rug pad should be about 1 inch smaller than your rug on all sides — so subtract 2 inches from both the length and the width of your rug. For example, for an 8×10 ft rug, you'd need a 7'10"×9'10" rug pad. This keeps the pad hidden while still protecting the floor and anchoring the rug.
For a dining room, the rug should extend at least 24 inches beyond the edge of the table on all sides. This ensures chairs remain on the rug even when pulled out. For a 6-person rectangular table (36×72 in), an 8×10 ft rug is typically the minimum recommended size.
Not always. A rug that's too large can overwhelm a space and make it feel cramped, while one that's too small looks like a 'postage stamp' floating in the room. The key is leaving the right amount of bare floor border — generally 18 to 24 inches — so the rug visually frames the furniture grouping without overtaking the room.
