Placement-based estimate

Rug size formula

The result starts with the furniture group rather than a fixed product size. The editable extension represents the rug visible beyond the sofa, dining table and pulled-out chairs, or bed.

Rug dimension = furniture dimension + (extension × 2)

Choose by layout, not label

Dining layouts need enough rug beyond the table for chairs to move without catching an edge. Bedroom and living-room choices depend on which furniture legs should sit on the rug. Use painter's tape to test the calculated outline.
