Recommendations snap your measurements to a standard rug size under the placement rules below. Furniture, not room size, decides the rug — when in doubt, size up.

Are all rugs standard sizes?
Mostly. About nine standard sizes cover the market — 3x5, 4x6, 5x8, 6x9, 8x10, 9x12, 10x14, 12x15 ft plus round 4–10 ft — and 5x8, 8x10 and 9x12 account for most of what is sold. That is why this planner recommends the nearest size you can actually buy.
- Brand sizes vary slightly. One maker's “8x10” might be 7'10"x9'10" and another's exactly 96"x120" — always check the listed dimensions.
- Custom is an option. Rugs can be cut to any size for more money and a longer lead time. Use the Exact need (custom) figure from the calculator for a made-to-order rug.
- Caught between two sizes? Size up. An undersized rug is the most common mistake.
How sizes are computed & sources
- We snap your entered room/furniture dimensions to the nearest standard rug size using published placement rules (wall border, table overhang, bed overhang).
- Numbers are interior-design guidelines, not exact science — the diagram shows the actual border/overhang so you can adjust. Measure your space and tape it out before buying.
- Standard sizes and bed dimensions are exact (e.g. 8x10 = 96x120 in = 244x305 cm; Queen 60x80 in, King 76x80 in).
- Decorative sizing only. No cleaning, installation, or product advice.
