What an 11 × 12 bedroom gives you
An 11 × 12 room measures 132 sq ft, a common secondary bedroom in newer houses where the builder squeezed one more foot out of the plan. A bed, two small nightstands and a dresser fit without the dresser crowding the door. An 8 × 10 ft rug leaves 1.5 ft down the sides and 1.0 ft at the ends, so most of the rug ends up under the bed.
Shopping list for the floor: 8 boxes of 20 sq ft plank (that is 145 sq ft including cuts), or 14.7 sq yd of carpet, which a 12 ft roll lays without a seam across the 11 ft width. Shopping list for the walls: 2 gallons covers 317 sq ft twice. Add 0.75 gallons if the ceiling is being done at the same time, and paint it first.
