A 16 × 18 great room: 288 square feet

Sixteen by eighteen gives 288 sq ft, nearly square, and big enough for a great room, a bonus room or a small studio apartment's main space. A single 12 × 15 ft rug leaves 2.0 ft at the sides and 1.5 ft at the ends. Many people use two smaller rugs to mark a seating group and a second area instead.

The perimeter is 68 ft, so plan on roughly that much baseboard less the doorways. At 8 ft the walls come to 544 sq ft; after a door and two windows 493 sq ft is left and two coats take 2.82 gallons. Rooms this size often have taller ceilings, and every extra foot of height adds 68 sq ft of wall. Flooring: 16 boxes, or 317 sq ft. Ceiling paint: 1.65 gallons for two coats.
