A 14 × 18 living room: 252 square feet
Fourteen by eighteen is 252 sq ft, a living room that takes a sectional, or a primary suite bedroom with a real sitting area. A 10 × 14 ft rug leaves an even 2.0 ft of floor on all four sides, so the rug looks centered from every doorway. From corner to corner it is 22.8 ft, worth knowing if you are checking whether a TV can be seen from the far seat.
At this size, quantities stop being trivial. Flooring is 14 boxes, heavy enough that delivery is worth pricing. Carpet has to be seamed because the room is wider than a 12 ft roll: about 37.3 sq yd off a 12 ft roll before the fitter plans the cuts. The walls total 512 sq ft at 8 ft, 461 to paint, and two coats need 2.63 gallons: 2 gallons + 3 quarts.
